Unable to get exact circle shape when using card view

Unable to get exact circle shape when using card view - android

I'm using card view for floating action button in android material design. I'm using following code for get the circle
<android.support.v7.widget.CardView
android:id="#+id/fab"
android:layout_width="38dp"
android:layout_height="38dp"
android:layout_marginBottom="10dp"
android:layout_marginRight="10dp"
card_view:background="#color/blue"
card_view:cardCornerRadius="19dp"
card_view:cardPreventCornerOverlap = "false"
card_view:cardElevation="6dp" >
</android.support.v7.widget.CardView>
I have set corner radius as half of width. but still I can't get the circle shape.

To achieve a circular shape using Card view you can set the shape property, android:shape="ring". app:cardCornerRadius should be set to half the width or height of the child view
<android.support.v7.widget.CardView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:innerRadius="0dp"
android:shape="ring"
app:cardCornerRadius="75dp">
<ImageView
android:layout_width="150dp"
android:layout_height="150dp"
android:layout_gravity="center"
android:background="#drawable/image" />
</android.support.v7.widget.CardView>

I have solved the problem. Now android providing design library for material design, which has the FloatingActionButton. No need of customizing card view for floating action button.
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="#dimen/fab_margin" />
Add design library in gradle dependencies
compile 'com.android.support:design:23.1.1'
For more detail refer this link

To get a perfect circle shape using a card view, corner radius should be 1/2 of width or height (taking into consideration that it is a square). also, I have noticed that you are using card_view params, don't.
<android.support.v7.widget.CardView
android:layout_width="38dp"
android:layout_height="38dp"
app:cardCornerRadius="19dp"
app:cardElevation="6dp"
android:layout_marginBottom="10dp"
android:layout_marginRight="10dp"
android:id="#+id/fab"
android:background="#color/blue"
>

use
shape = "ring"
use same layout_height and layout_weight
and
app:cardCornerRadius= half of layout_height or layout_weight
example
<android.support.v7.widget.CardView
android:id="#+id/cardview"
android:layout_width="110dp"
android:layout_height="110dp"
android:shape="ring"
app:cardCornerRadius="55dp">
</android.support.v7.widget.CardView>

<androidx.cardview.widget.CardView
android:layout_width="60dp"
android:layout_marginStart="150dp"
app:cardCornerRadius="360dp"
android:layout_height="60dp">

I came up with simple Solution of Using a Drawable and it looks amazing!
Get Drawable here
https://drive.google.com/drive/folders/0B4Vo_ku-aIKzUFFnUjYxYVRLaGc?resourcekey=0-RiH8lUO0i1kwnZsqquqjnQ&usp=sharing

I tried your code and found out that the Cards were less round with respect to the increase in the card elevation value.Try setting it to zero and this at least makes it look better.
card_view:cardElevation="0dp";
But a probably better option would be to use the FloatingActionButton for the round button
<android.support.design.widget.FloatingActionButton
android:src="#drawable/your_drawble_name"
app:fabSize="normal"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />

add this line to the CardView which sets the cardCornerRadius to the Circle diameter.
app:cardCornerRadius="360dp"

Yes, I have achieved it by reducing half of the CardCornerRadius to its View's Height.

card_layout.xml
<android.support.v7.widget.CardView
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:id="#+id/card_view"
android:layout_gravity="center"
android:layout_width="250dp"
android:layout_height="200dp">
<ImageView
android:id="#+id/card_thumbnail_image"
android:layout_height="match_parent"
android:layout_width="match_parent"
style="#style/card_thumbnail_image"/>
</android.support.v7.widget.CardView>
MainActivity.java
ImageView imageView = (ImageView) findViewById(R.id.card_thumbnail_image);
Bitmap mBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.rose);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP){
//Default
imageView.setBackgroundResource(R.drawable.rose);
} else {
//RoundCorners
RoundCornersDrawable round = new RoundCornersDrawable(mBitmap,
getResources().getDimension(R.dimen.cardview_default_radius), 0); //or your custom radius
CardView cardView = (CardView) findViewById(R.id.card_view);
cardView.setPreventCornerOverlap(false); //it is very important
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN)
imageView.setBackground(round);
else
imageView.setBackgroundDrawable(round);
}
RoundCornersDrawable.java
public class RoundCornersDrawable extends Drawable {
private final float mCornerRadius;
private final RectF mRect = new RectF();
//private final RectF mRectBottomR = new RectF();
//private final RectF mRectBottomL = new RectF();
private final BitmapShader mBitmapShader;
private final Paint mPaint;
private final int mMargin;
public RoundCornersDrawable(Bitmap bitmap, float cornerRadius, int margin) {
mCornerRadius = cornerRadius;
mBitmapShader = new BitmapShader(bitmap,
Shader.TileMode.CLAMP, Shader.TileMode.CLAMP);
mPaint = new Paint();
mPaint.setAntiAlias(true);
mPaint.setShader(mBitmapShader);
mMargin = margin;
}
#Override
protected void onBoundsChange(Rect bounds) {
super.onBoundsChange(bounds);
mRect.set(mMargin, mMargin, bounds.width() - mMargin, bounds.height() - mMargin);
//mRectBottomR.set( (bounds.width() -mMargin) / 2, (bounds.height() -mMargin)/ 2,bounds.width() - mMargin, bounds.height() - mMargin);
// mRectBottomL.set( 0, (bounds.height() -mMargin) / 2, (bounds.width() -mMargin)/ 2, bounds.height() - mMargin);
}
#Override
public void draw(Canvas canvas) {
canvas.drawRoundRect(mRect, mCornerRadius, mCornerRadius, mPaint);
//canvas.drawRect(mRectBottomR, mPaint); //only bottom-right corner not rounded
//canvas.drawRect(mRectBottomL, mPaint); //only bottom-left corner not rounded
}
#Override
public int getOpacity() {
return PixelFormat.TRANSLUCENT;
}
#Override
public void setAlpha(int alpha) {
mPaint.setAlpha(alpha);
}
#Override
public void setColorFilter(ColorFilter cf) {
mPaint.setColorFilter(cf);
}
}

first import the drawbleToolBox library in your project.
with this library, you can create drawable dynamically.
for make your cardview circle your radius must be half of its height/widht.
int radius = cardView.getHeight()/2;
Drawable drawable = new DrawableBuilder()
.rectangle()
.solidColor(0xffffffff)
.topRightRadius(radius) // in pixels
.bottomRightRadius(radius)
//otherplaces
.build();
holder.cardView.setBackground(drawable);
if you are using cardview in your recycleview, getting the cardview widths doesn't work
becuse it doesn't create yet. so you should do as below
holder.cardView.getViewTreeObserver().addOnPreDrawListener(new ViewTreeObserver.OnPreDrawListener()
{
#Override
public boolean onPreDraw()
{
//codes here.
}
}

Using CardView to obtain circular background with shadow can be quiet troublesome intead use layer-list in drawable to get the desired output.
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="oval">
<!--shadow color you want-->
<solid android:color="#C3C1C1"/>
</shape>
</item>
<item
android:left="0dp"
android:right="0dp"
android:top="0dp"
android:bottom="2dp">
<shape android:shape="oval">
<solid android:color="#color/white"/>
</shape>
</item>
</layer-list>

Anchor an ImageView to corner of another ImageView

How to anchor an ImageView to bottom right corner of another ImageView like the ones in the above picture (1-man and 2-pencil)
I am using retrofit to load my sources as oval into ImageViews
I do this :
Glide.with(context)
.asBitmap()
.load(model)
.fitCenter()
.apply(RequestOptions.circleCropTransform())
.into(object : BitmapImageViewTarget(this) {
override fun setResource(resource: Bitmap?) {
setImageDrawable(
resource?.run {
RoundedBitmapDrawableFactory.create(
resources,
if (borderSize > 0) {
createBitmapWithBorder(borderSize, borderColor)
} else {
this
}
).apply {
isCircular = true
}
}
)
}
})

Base concept
To build such layout you can use for example ConstraintLayout or RelativeLayout.
Using RelativeLayout you can build such structure:
<RelativeLayout
android:layout_width="200dp"
android:layout_height="200dp">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginEnd="20dp"
android:layout_marginBottom="20dp"
android:background="#00f" />
<ImageView
android:layout_width="70dp"
android:layout_height="70dp"
android:layout_alignParentEnd="true"
android:layout_alignParentBottom="true"
android:background="#f0f" />
</RelativeLayout>
Which should look like there:
Small circle
For smaller circle (grey one) you can use only one ImageView. Just set light background - as background and pen icon - as src.
1) For ImageView background you have to create new drawable with two shapes. First ont is for white border around, second it's just light gray background.
You can set padding second shape (here, in example, there is 5dp)
<?xml version="1.0" encoding="utf-8"?><?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="oval">
<solid android:color="#FFFFFF" />
</shape>
</item>
<item
android:bottom="5dp"
android:left="5dp"
android:right="5dp"
android:top="5dp">
<shape android:shape="oval">
<solid android:color="#CACACA" />
</shape>
</item>
</layer-list>
2) As icon you can use drawable (e.g. vector) or just image and set it as src
After this point it should look like there:
3) Set padding in ImageView to scale your (pen) icon correctly:
<ImageView
android:layout_width="70dp"
android:layout_height="70dp"
android:layout_alignParentEnd="true"
android:layout_alignParentBottom="true"
android:background="#drawable/small_circle_background"
android:padding="16dp"
android:src="#drawable/small_circle_icon" />
Big circle
Best approach is to use some library like Picasso or Glide.
For Glide, you can use CircleTransform() to crop received image in to circle. When loading image you can just use transform() method:
Glide.with(this)
.load(URL)
.transform(new CircleTransform(context))
.into(imageView);
When CircleTransform is:
import android.graphics.Bitmap;
import android.graphics.BitmapShader;
import android.graphics.Canvas;
import android.graphics.Paint;
import androidx.annotation.NonNull;
import com.bumptech.glide.load.engine.bitmap_recycle.BitmapPool;
import com.bumptech.glide.load.resource.bitmap.BitmapTransformation;
import org.jetbrains.annotations.NotNull;
import java.security.MessageDigest;
public class CircleTransform extends BitmapTransformation {
#Override protected Bitmap transform(#NotNull BitmapPool pool, #NotNull Bitmap toTransform, int outWidth, int outHeight) {
return circleCrop(pool, toTransform);
}
private static Bitmap circleCrop(BitmapPool pool, Bitmap source) {
if (source == null) return null;
int size = Math.min(source.getWidth(), source.getHeight());
int x = (source.getWidth() - size) / 2;
int y = (source.getHeight() - size) / 2;
Bitmap squared = Bitmap.createBitmap(source, x, y, size, size);
Bitmap result = pool.get(size, size, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(result);
Paint paint = new Paint();
paint.setShader(new BitmapShader(squared, BitmapShader.TileMode.CLAMP, BitmapShader.TileMode.CLAMP));
paint.setAntiAlias(true);
float r = size / 2f;
canvas.drawCircle(r, r, r, paint);
return result;
}
#Override
public void updateDiskCacheKey(#NonNull MessageDigest messageDigest) {
}
}
Final result

You can achieve what you want like this:
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:layout_width="100dp"
android:layout_height="100dp"
android:src="#drawable/first_image"/>
<ImageView
android:layout_width="40dp"
android:layout_height="40dp"
android:src="#drawable/second"
android:layout_gravity="bottom|right"/>
</FrameLayout>

Rounded corner google map android? [duplicate]

I want to give the map a nice looking rounded corners as the two boxes below it have.
I can't do it with the map fragment it self because there is not a background property to a
fragment.
setting the map inside a layout and setting it background to a rounded shape didn't help me
as well and this is the result:
I could merge the map but this would make it smaller and i would like to avoid it.
EDIT:
#Ryan this is the new result #2:
I guess this is not bad, no even close to the corners on the other boxes,
but still not bad with a little more work a could get somewhere close i just dont have a normal image editor.
but one thing that still bothers me now is the separation between the "Location" Textview and the map it's self. could i painted the patch in other way so that there was now distance? this is how i did it:
Well I have finally figured this out:
this is what i used for the patch:
Thanks.

I know it's an old post, but you can try using Cards like so:
<android.support.v7.widget.CardView
android:layout_width="300dp"
android:layout_height="350dp"
android:layout_gravity="center_horizontal|center_vertical"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:layout_marginTop="20dp"
app:cardCornerRadius="12dp"
app:cardElevation="12dp">
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</android.support.v7.widget.CardView>

I haven't tried this, but I'd put a view with rounded corners and a transparent middle on top of the mapView / mapFragment.
That is, put the mapFragment and the rounded corner view in a FrameLayout with both filling the FrameLayout, then make the middle of the rounded corner view transparent.
For further clarification, you could do it in a layout as follows:-
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<fragment
xmlns:map="http://schemas.android.com/apk/res-auto"
android:id="#+id/mapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.MapFragment" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/rounded_background"
android:orientation="vertical" >
</LinearLayout>
</FrameLayout>
The rounded_background is a 9-patch with rounded corners and a transparent middle. E.g.
Hope that helps,
Ryan

The easiest way is to wrap the map fragment inside a FrameLayout along with an ImageView. The Imageview would display a rounded rectangle on top of the map fragment. In its simplest form you will see the map fragment inside the rounded rectangle with its corners sticking out of the rounded rectangle because the map view itself is not rounded. To overcome this visual oddity simply apply a layout_margin value on map fragment. The value should be equal to the rectangle's border width.
<FrameLayout
android:id="#+id/map_container"
android:layout_width="wrap_content"
android:layout_height="340dp" >
<fragment
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="3dp"
android:name="com.google.android.gms.maps.SupportMapFragment"/>
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/map_bg_box" />
</FrameLayout>
The rectangle drawable is defined as an xml shape as below
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke android:width="3dp"
android:color="#ff000000" />
<corners android:bottomRightRadius="7dp" android:bottomLeftRadius="7dp"
android:topLeftRadius="7dp" android:topRightRadius="7dp"/>
</shape>
Notice the stroke width of the rectangle is 3dp that is exactly the same value we applied to the layout_margin property of the map fragment. The result is a nicely round cornered map fragment as shown in the screenshot below

Wrap the map fragment in this layout:
package com.example.yourpackage;
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Paint;

mPathCorners.reset();
mPathCorners.addRoundRect(rect, mCornerRadius, mCornerRadius, Path.Direction.CW);
mPathCorners.close();
// circle path
halfWidth = w / 2f;

mPathCornersBorder.reset();
mPathCornersBorder.addRoundRect(rectBorder, mCornerRadius - mBorderHalf, mCornerRadius -
mBorderHalf, Path.Direction.CW);
mPathCornersBorder.close();
}
}
In layout will be like this:
<com.example.yourpackage.RoundedLayout
android:id="#+id/maplayout"
android:layout_width="match_parent"
android:layout_height="200dp"
android:layout_margin="20dp">
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="200dp"
tools:context="com.example.yourpackage.MapsMarkerActivity"/>
</com.example.yourpackage.RoundedLayout>
In code can be like this for a round shape with border:
RoundedLayout rl = (RoundedLayout) findViewById(R.id.maplayout);
rl.setShapeCircle(true);
rl.showBorder(true);
rl.setBorderWidth(2);
This layout can be used to shape any view.
It's incredible how google is incapable of making competent (usable) complete demos for it's android API.

For other people looking into this, I just tackled this using GoogleMap.snapshot and manipulating the bitmap result with this stack over flow answer:
How to make an ImageView with rounded corners?
Mind you this is only valid if you are going to have a static map that is not going to be interacted with.
Make sure you take the snap shot after the map is loaded.
I updated the image view helper code to draw with path to support rounding only some corners. ie. If you want to round only 2 of the corners.
You just need the path round rect function that takes a float[]
I show a progress bar until I get a callback from GoogleMap loaded listener than I take the snapshot.
If you take your snapshot too early you will get can't create bitmap with 0 width and height error.
Hope this helps someone looking for rounded corners or other weird shape in static map snapshot.

If you are only trying to target API 21 (Lollipop) and higher
This is the easiest way possible.
parentView.setClipToOutline(true);

Following #Nouman_Hanif post I ended up with a solution that looks quite good.

How to fit image in circular border and rectangular border [duplicate]

I'd Like to make any image from my ImageView to be circular with a border.
I searched but couldn't find any useful information (anything that I tried didn't work).
How can I achieve this through XML:
Create an ImageView with certain src and make it circular with a border?

This is the simplest way that I designed. Try this.
dependencies
implementation 'androidx.appcompat:appcompat:1.3.0-beta01'
implementation 'androidx.cardview:cardview:1.0.0'

If you are working on android versions above lollipop

android:scaleType="centerCrop"/>
</android.support.v7.widget.CardView>
Adding Border to round ImageView - LATEST VERSION
Wrap it with another CardView slightly bigger than the inner one and set its background color to add a border to your round image. You can increase the size of the outer CardView to increase the thickness of the border.
<androidx.cardview.widget.CardView
android:layout_width="155dp"
android:layout_height="155dp"
app:cardCornerRadius="250dp"
app:cardBackgroundColor="#color/white">
<androidx.cardview.widget.CardView
android:layout_width="150dp"
android:layout_height="150dp"
app:cardCornerRadius="250dp"
android:layout_gravity="center">
<ImageView
android:layout_width="150dp"
android:layout_height="150dp"
android:src="#drawable/default_user"
android:scaleType="centerCrop"/>
</androidx.cardview.widget.CardView>
</androidx.cardview.widget.CardView>

You can make a simple circle with white border and transparent content with shape.
// res/drawable/circle.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:innerRadius="0dp"
android:shape="ring"
android:thicknessRatio="1.9"
android:useLevel="false" >
<solid android:color="#android:color/transparent" />
<stroke
android:width="10dp"
android:color="#android:color/white" />
</shape>
Then make a layerlist drawable and put it as background to your imageview.
// res/drawable/img.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="#drawable/circle"/>
<item android:drawable="#drawable/ic_launcher"/>
</layer-list>
and put it as background to your imageview.
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/img"/>
You'll have something like that.

With the Material Components Library Just use the ShapeableImageView.
Somethig like:
<com.google.android.material.imageview.ShapeableImageView
app:shapeAppearanceOverlay="#style/roundedImageViewRounded"
app:strokeColor="#color/....."
app:strokeWidth="1dp"
...
/>
with:
<style name="roundedImageViewRounded">
<item name="cornerFamily">rounded</item>
<item name="cornerSize">50%</item>
</style>
Note: it requires at least the version 1.2.0.
With jetpack compose you can apply the clip Modifier using a CircleShape:
Image(
painter = painterResource(R.drawable.xxxx),
contentDescription = "xxxx",
contentScale = ContentScale.Crop,
modifier = Modifier
.size(100.dp)
.clip(CircleShape)
.border(2.dp, Color.Blue, CircleShape)
)

I hope this will help you.

With the help of glide library and RoundedBitmapDrawableFactory class it's easy to achieve. You may need to create circular placeholder image.
Glide V4:
Glide.with(context).load(url).apply(RequestOptions.circleCropTransform()).into(imageView);
Glide V3:
Glide.with(context)
.load(imgUrl)
.asBitmap()
.placeholder(R.drawable.placeholder)
.error(R.drawable.placeholder)
.into(new BitmapImageViewTarget(imgProfilePicture) {
#Override
protected void setResource(Bitmap resource) {
RoundedBitmapDrawable drawable = RoundedBitmapDrawableFactory.create(context.getResources(),
Bitmap.createScaledBitmap(resource, 50, 50, false));
drawable.setCircular(true);
imgProfilePicture.setImageDrawable(drawable);
}
});
For Picasso RoundedTransformation, this is a really great solution that gives an additional option of rounding image at either top or bottom edge.

The above methods don't seem to work if you're using the src attribute. What I did is to put two image views inside a frame layout one above another like this:
<FrameLayout android:id="#+id/frame"
android:layout_width="40dp"
android:layout_height="40dp">
<ImageView android:id="#+id/pic"
android:layout_width="40dp"
android:layout_height="40dp"
android:src="#drawable/my_picture" />
<ImageView android:id="#+id/circle_crop"
android:layout_width="40dp"
android:layout_height="40dp"
android:src="#drawable/circle_crop" />
</FrameLayout>
Simply put a circular_crop.png in your drawable folder which is in the shape of your image dimensions (a square in my case) with a white background and a transparent circle in the center. You can use this image if you have want a square imageview.
Just download the picture above.

The following is one of the simplest ways to do it, use the following code:
Dependencies
dependencies {
...
compile 'de.hdodenhof:circleimageview:2.1.0' // use this or use the latest compile version. In case u get bug.
}
XML Code
<de.hdodenhof.circleimageview.CircleImageView
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/profile_image"
android:layout_width="96dp" // here u can adjust the width
android:layout_height="96dp" // here u can adjust the height
android:src="#drawable/profile" // here u can change the image
app:civ_border_width="2dp" // here u can adjust the border of the circle.
app:civ_border_color="#FF000000"/> // here u can adjust the border color

you don't need any third-party library.
you can use the ShapeableImageView in the material.
implementation 'com.google.android.material:material:1.2.0'
style.xml
<style name="ShapeAppearanceOverlay.App.CornerSize">
<item name="cornerSize">50%</item>
</style>
in layout
<com.google.android.material.imageview.ShapeableImageView
android:layout_width="100dp"
android:layout_height="100dp"
app:srcCompat="#drawable/ic_profile"
app:shapeAppearanceOverlay="#style/ShapeAppearanceOverlay.App.CornerSize"
/>
you can see this
https://developer.android.com/reference/com/google/android/material/imageview/ShapeableImageView
or this
https://medium.com/android-beginners/shapeableimageview-material-components-for-android-cac6edac2c0d

You can simply use AndroidX ImageFilterView.
<androidx.constraintlayout.utils.widget.ImageFilterView
android:layout_width="48dp"
android:layout_height="48dp"
android:layout_marginStart="#dimen/margin_medium"
android:layout_marginBottom="#dimen/margin_medium"
android:background="#color/white"
android:padding="#dimen/margin_small"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:roundPercent="1"
app:srcCompat="#drawable/ic_gallery" />

You can simply use CardView without any external Library
<androidx.cardview.widget.CardView
android:id="#+id/roundCardView"
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_centerHorizontal="true"
android:elevation="0dp"
app:cardCornerRadius="20dp">
<ImageView
android:layout_width="40dp"
android:layout_height="40dp"
android:src="#drawable/profile" />
</androidx.cardview.widget.CardView>

This will do the trick:
rectangle.xml
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#android:color/transparent" />
<padding android:bottom="-14dp" android:left="-14dp" android:right="-14dp" android:top="-14dp" />
</shape>
circle.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:innerRadius="0dp"
android:shape="oval"
android:useLevel="false" >
<solid android:color="#android:color/transparent" />
<stroke
android:width="15dp"
android:color="#color/verification_contact_background" />
</shape>
profile_image.xml ( The layerlist )
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="#drawable/rectangle" />
<item android:drawable="#drawable/circle"/>
</layer-list>
Your layout
<ImageView
android:id="#+id/profile_image"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/default_org"
android:src="#drawable/profile_image"/>

Posting this answer for future reference. You can use ShapeableImageView available in com.google.android.material:material.
<com.google.android.material.imageview.ShapeableImageView
android:id="#+id/img_launcher_icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_margin="5dp"
android:adjustViewBounds="true"
android:background="#android:color/transparent"
android:elevation="5dp"
android:maxWidth="50dp"
android:maxHeight="50dp"
android:scaleType="fitXY"
android:src="#mipmap/ic_launcher"
app:shapeAppearance="?attr/actionButtonStyle"
app:shapeAppearanceOverlay="#style/imageViewRounded"
app:strokeColor="#android:color/white" />
Add imageViewRounded style in your styles.xml
<style name="imageViewRounded">
<item name="cornerFamily">rounded</item>
<item name="cornerSize">51%</item>
</style>
You can add material design dependency if not added.
implementation 'com.google.android.material:material:1.4.0'
Design looks like

Best Solution courtesy https://www.youtube.com/watch?v=0MHoNU7ytaw
the width and height of the card view determine the size of the images it contains set up is as follows:
Add Dependency to Gradle(Module)
Add the xml code to activity.xml or fragment.xml file
implementation 'androidx.cardview:cardview:1.0.0'
<androidx.cardview.widget.CardView
android:layout_width="300dp"
android:layout_height="270dp"
android:layout_gravity="center"
app:cardCornerRadius="150dp"
app:cardBackgroundColor="#color/trans"
>
<ImageView
android:id="#+id/resultImage"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/congrats"
android:layout_gravity="center">
</ImageView>
</androidx.cardview.widget.CardView>```

Update 2021: Using Glide v4 CircleCrop see https://bumptech.github.io/glide/doc/generatedapi.html
implementation 'com.github.bumptech.glide:glide:4.11.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.11.0'
XML
<ImageView
android:id="#+id/vinyl"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:ignore="ContentDescription" />
In Code
Glide.with(this)
.load("https://images.pexels.com/photos/3828241/pexels-photo-3828241.jpeg")
.transform(CircleCrop())
.into(rootView.findViewById<ImageView>(R.id.vinyl))

I use shape = "oval" instead of the "ring" below. It has worked for me. To keep the image within bounds, I use <padding> and set <adjustViewBounds> to true in my <ImageView>. I have tried with images of size between 50 x 50 px upto 200x200 px .

#Jyotman Singh, answer is very good (for solid backgrounds), so I would like to enhance it by sharing vector drawable that can be re-colored for your needs, also it is convenient since vector one-piece shape is well scalable.
This is the rectangle-circle shape (#drawable/shape_round_profile_pic):
<?xml version="1.0" encoding="utf-8"?>
<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:viewportWidth="284"
android:viewportHeight="284"
android:width="284dp"
android:height="284dp">
<path
android:pathData="M0 142L0 0l142 0 142 0 0 142 0 142 -142 0 -142 0zm165 137.34231c26.06742 -4.1212 52.67405 -17.543 72.66855 -36.65787 11.82805 -11.30768 20.55487 -22.85153 27.7633 -36.72531C290.23789 158.21592 285.62874 101.14121 253.48951 58.078079 217.58149 9.9651706 154.68849 -10.125717 98.348685 8.5190299 48.695824 24.95084 12.527764 67.047123 3.437787 118.98655 1.4806194 130.16966 1.511302 152.96723 3.4990422 164.5 12.168375 214.79902 47.646316 256.70775 96 273.76783c21.72002 7.66322 44.26673 9.48476 69 5.57448z"
android:fillColor="#ffffff" /> // you can change frame color
</vector>
Usage is the same:
<FrameLayout
android:layout_width="70dp"
android:layout_height="70dp">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/YOUR_PICTURE" />
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/shape_round_profile_pic"/>
</FrameLayout>

Just use these lines of code and you are done :
<de.hdodenhof.circleimageview.CircleImageView
xmlns:app="http://schemas.android.com/apk/res-auto"
android:clickable="true"
app:civ_border_width="3dp"
app:civ_border_color="#FFFFFFFF"
android:id="#+id/profile"
android:layout_width="200dp"
android:layout_height="200dp"
android:layout_below="#+id/header_cover_image"
android:layout_centerHorizontal="true"
android:layout_marginTop="-130dp"
android:elevation="5dp"
android:padding="20dp"
android:scaleType="centerCrop"
android:src="#drawable/profilemain" />
Don't forget to import :
import de.hdodenhof.circleimageview.CircleImageView;
Add this library in build.gradle :
compile 'de.hdodenhof:circleimageview:2.1.0'

If you use Material Design in your app then use this
<com.google.android.material.card.MaterialCardView
android:layout_width="75dp"
android:layout_height="75dp"
app:cardCornerRadius="50dp"
app:strokeWidth="1dp"
app:strokeColor="#color/black">
<ImageView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/circular_image"
android:scaleType="fitCenter"
android:src="#drawable/your_img" />
</com.google.android.material.card.MaterialCardView>

I did it like that, I used my background color in my vector image
ic_bg_picture.xml
<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:width="100dp"
android:height="100dp"
android:viewportWidth="100"
android:viewportHeight="100">
<path
android:pathData="M100.6,95.5c0,-0.4 -0.1,-0.7 0,-1.1c-0.2,-0.7 -0.2,-1.4 -0.1,-2.1c0,-0.1 0,-0.2 0,-0.3c-0.1,-0.6 -0.1,-1.2 0,-1.8c-1,-1.3 -0.3,-2.9 -0.3,-4.3c-0.1,-28.7 -0.1,-57.3 -0.1,-86C68,-0.1 35.9,-0.1 3.8,-0.2C0.7,-0.2 0,0.5 0,3.6c0.1,32.1 0.1,64.2 0.1,96.2c31,0 62,-0.1 92.9,0.1c3.6,0 6.3,-0.2 7.5,-3.2C100.5,96.4 100.5,95.9 100.6,95.5zM46.3,95.2C26.4,94 2,74.4 3.8,46.8C5.1,27.2 24.4,2.7 52.6,4.6c20.2,1.4 43,21.3 41.5,45.1C96.1,72.4 73,96.8 46.3,95.2z"
android:fillColor="#6200EE"/>
</vector>
in my case I created a vector and changed the android:fillColor="#6200EE"
by the color of my background
<ImageView
android:id="#+id/iv_profile_image"
android:layout_width="100dp"
android:layout_height="100dp"
android:contentDescription="#string/app_name"
app:srcCompat="#color/colorPrimaryDark" />
<ImageView
android:id="#+id/container_profile_image"
android:layout_width="100dp"
android:layout_height="100dp"
android:contentDescription="#string/app_name"
app:srcCompat="#drawable/ic_bg_picture"/>

Another method without using any library is using ImageFilterView and setting round percentage to the view will make the circle round
app:roundPercent="1"
<androidx.constraintlayout.utils.widget.ImageFilterView
android:id="#+id/ivProfile"
android:layout_width="150dp"
android:layout_height="150dp"
android:src="#drawable/custom_button_1"
app:roundPercent="1"
android:scaleType="fitXY"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintBottom_toTopOf="#+id/etName"/>

Try this.

Actually, you can use what Google provides via the support library RoundedBitmapDrawableFactory class (here and here), instead of using a third party library :
Gradle:
implementation 'androidx.appcompat:appcompat:1.0.0-beta01'
MainActivity.kt
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val originalDrawable = ContextCompat.getDrawable(this, R.drawable.avatar_1)!!
val bitmap = convertDrawableToBitmap(originalDrawable)
val drawable = RoundedBitmapDrawableFactory.create(resources, bitmap)
drawable.setAntiAlias(true)
drawable.cornerRadius = Math.max(bitmap.width, bitmap.height) / 2.0f
avatarImageView.setImageDrawable(drawable)
}
companion object {
#JvmStatic
fun convertDrawableToBitmap(drawable: Drawable): Bitmap {
if (drawable is BitmapDrawable)
return drawable.bitmap
// We ask for the bounds if they have been set as they would be most
// correct, then we check we are > 0
val bounds = drawable.bounds
val width = if (!bounds.isEmpty) bounds.width() else drawable.intrinsicWidth
val height = if (!bounds.isEmpty) bounds.height() else drawable.intrinsicHeight
// Now we check we are > 0
val bitmap = Bitmap.createBitmap(if (width <= 0) 1 else width, if (height <= 0) 1 else height,
Bitmap.Config.ARGB_8888)
val canvas = Canvas(bitmap)
drawable.setBounds(0, 0, canvas.width, canvas.height)
drawable.draw(canvas)
return bitmap
}
}
}

The result:
And, suppose you want to add a border on top of it, you can use this for example:
stroke_drawable.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval">
<stroke
android:width="4dp" android:color="#android:color/black"/>
</shape>
And add android:foreground="#drawable/stroke_drawable" to the ImageView in the layout XML file, and you get this :
I'm not sure how to add shadow (that will work on older Android versions), though. Using FloatingActionButton (from the "com.google.android.material:material" dependency), I failed to make the bitmap fill the FAB itself. Using it instead could be even better if it worked.
EDIT: if you wish to add shadow of elevation (available from API 21), you can change a bit what I wrote:
Inside the layout XML file:
<androidx.appcompat.widget.AppCompatImageView android:padding="4dp"
android:id="#+id/avatarImageView" android:layout_width="100dp" android:layout_height="100dp" android:elevation="8dp"
android:layout_gravity="center" android:background="#drawable/stroke_drawable" tools:srcCompat="#drawable/avatar_1"/>
CircularShadowViewOutlineProvider.kt
#TargetApi(Build.VERSION_CODES.LOLLIPOP)
class CircularShadowViewOutlineProvider : ViewOutlineProvider() {
override fun getOutline(view: View, outline: Outline) {
val size = Math.max(view.width, view.height)
outline.setRoundRect(0, 0, size, size, size / 2f)
}
}
In code:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
avatarImageView.outlineProvider = CircularShadowViewOutlineProvider()
Result:

I have a simple solution.
Create a new Image asset by right clicking your package name and selecting New->Image asset.
Enter name (any name) and path (location of image in your system).
Then click Next and Finish.
If you enter name of image as 'img', a round image with the name 'img_round' is created automatically in mipmap folder.
Then, do this :
<ImageView
android:layout_width="100dp"
android:layout_height="100dp"
android:src="#mipmap/img_round"/>
Your preview may still show a rectangular image. But if you run the app on your device, it will be round.

Create a CustomImageview then simply override its onDraw() method follows:
#Override
protected void onDraw(Canvas canvas) {
float radius = this.getHeight()/2;
Path path = new Path();
RectF rect = new RectF(0, 0, this.getWidth(), this.getHeight());
path.addRoundRect(rect, radius, radius, Path.Direction.CW);
canvas.clipPath(path);
super.onDraw(canvas);
}
In case you want the code for the custom widget as well:-
CircularImageView.java
import android.content.Context;
import android.content.res.TypedArray;
import android.graphics.Canvas;
import android.graphics.Path;
import android.graphics.RectF;
import android.graphics.drawable.Drawable;
import android.util.AttributeSet;
import android.widget.ImageView;
import androidx.annotation.Nullable;
public class CircularImageView extends ImageView {
private Drawable image;
public CircularImageView(Context context) {
super(context);
init(null, 0);
}
public CircularImageView(Context context, #Nullable AttributeSet attrs) {
super(context, attrs);
init(attrs, 0);
}
public CircularImageView(Context context, #Nullable AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
init(attrs, defStyleAttr);
}
#Override
protected void onDraw(Canvas canvas) {
float radius = this.getHeight()/2;
Path path = new Path();
RectF rect = new RectF(0, 0, this.getWidth(), this.getHeight());
path.addRoundRect(rect, radius, radius, Path.Direction.CW);
canvas.clipPath(path);
super.onDraw(canvas);
}
private void init(AttributeSet attrs, int defStyle) {
TypedArray a = Utils.CONTEXT.getTheme().obtainStyledAttributes(attrs, R.styleable.CircularImageView, 0, 0);
try {
image = a.getDrawable(R.styleable.CircularImageView_src);
} finally {
a.recycle();
}
this.setImageDrawable(image);
}
}
Also, add the following code to your res/attrs.xml to create the required attribute:-
<declare-styleable name="CircularImageView">
<attr name="src" format="reference" />
</declare-styleable>

if you want to set edit icon on to circle imageview than put this below code.
<FrameLayout
android:layout_width="#dimen/_100sdp"
android:layout_height="#dimen/_100sdp"
android:layout_gravity="center"
android:layout_marginTop="10dp">
<de.hdodenhof.circleimageview.CircleImageView
android:id="#+id/profilePic"
android:layout_width="#dimen/_100sdp"
android:layout_height="#dimen/_100sdp"
android:layout_gravity="bottom|center_horizontal"
android:src="#drawable/ic_upload" />
<de.hdodenhof.circleimageview.CircleImageView
android:id="#+id/iv_camera"
android:layout_width="#dimen/_30sdp"
android:layout_height="#dimen/_30sdp"
android:layout_gravity="top|right"
android:src="#drawable/edit"/>
</FrameLayout>

if you'd rather cut the image to display in circular, here you go
public static Bitmap getCircularBitmap(Bitmap bitmap) {
Bitmap output;
if (bitmap.getWidth() > bitmap.getHeight()) {
output = Bitmap.createBitmap(bitmap.getHeight(), bitmap.getHeight(), Bitmap.Config.ARGB_8888);
} else {
output = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getWidth(), Bitmap.Config.ARGB_8888);
}
Canvas canvas = new Canvas(output);
final int color = 0xff424242;
final Paint paint = new Paint();
final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());
float r = 0;
if (bitmap.getWidth() > bitmap.getHeight()) {
r = bitmap.getHeight() / 2;
} else {
r = bitmap.getWidth() / 2;
}
paint.setAntiAlias(true);
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(color);
canvas.drawCircle(r, r, r, paint);
paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
canvas.drawBitmap(bitmap, rect, rect, paint);
return output;
}

Another idea is to use clipToOutline property of an ImageView.
Here is an example layout:
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Simple view to draw borders for an image,
borders will be rounded because of the oval-shaped background. -->
<View
android:id="#+id/v_border"
android:layout_width="50dp"
android:layout_height="50dp"
android:background="#drawable/shape_border"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<!-- Image itself: fits the border view,
a margin serves as a border width;
the key point here - is a background shape which will clip the view to its forms. -->
<ImageView
android:id="#+id/iv_image"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_margin="4dp"
android:background="#drawable/shape_oval"
android:src="#mipmap/ic_launcher"
app:layout_constraintBottom_toBottomOf="#+id/v_border"
app:layout_constraintEnd_toEndOf="#+id/v_border"
app:layout_constraintStart_toStartOf="#+id/v_border"
app:layout_constraintTop_toTopOf="#+id/v_border" />
</androidx.constraintlayout.widget.ConstraintLayout>
And here are our shape_border drawable:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval">
<solid android:color="#FF00FF" />
</shape>
And shape_oval drawable:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval" />
The only thing you should do in the code - is to enable clipToOutline property:
binding.ivImage.clipToOutline = true
And of course you can avoid even this line of the code with some BindingAdapter.

This is a relatively old question, but you can just make a circle border in the drawable folder (let's assume the xml file will be called circle_border)
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="#android:color/transparent" />
<!-- If you want a padding -->
<padding android:top="4dp" android:left="4dp" android:right="4dp" android:bottom="4dp" />
<!-- If you want the circle border to have a color -->
<strong android:width="1dp" android:color="#FFFFFF" />
</shape>
Then you can use it as the background of the ImageView
<ImageView
android:background="#drawable/circle_border"
<!-- other attributes here -->
/>

just use this simple code:
First add dependency :
implementation 'de.hdodenhof:circleimageview:2.2.0'
then add in xml layout the following code:-
<de.hdodenhof.circleimageview.CircleImageView xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/Imgshaligram"
android:layout_width="96dp"
android:layout_height="96dp"
android:src="#drawable/shaligram"
app:civ_border_color="#d1b1b1"
android:foregroundGravity="center"/>

ImageView in circular through XML

I'd Like to make any image from my ImageView to be circular with a border.
I searched but couldn't find any useful information (anything that I tried didn't work).
How can I achieve this through XML:
Create an ImageView with certain src and make it circular with a border?

This is the simplest way that I designed. Try this.
dependencies
implementation 'androidx.appcompat:appcompat:1.3.0-beta01'
implementation 'androidx.cardview:cardview:1.0.0'
<android.support.v7.widget.CardView
android:layout_width="80dp"
android:layout_height="80dp"
android:elevation="12dp"
android:id="#+id/view2"
app:cardCornerRadius="40dp"
android:layout_centerHorizontal="true"
android:innerRadius="0dp"
android:shape="ring"
android:thicknessRatio="1.9">
<ImageView
android:layout_height="80dp"
android:layout_width="match_parent"
android:id="#+id/imageView1"
android:src="#drawable/YOUR_IMAGE"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true">
</ImageView>
</android.support.v7.widget.CardView>
If you are working on android versions above lollipop
<android.support.v7.widget.CardView
android:layout_width="80dp"
android:layout_height="80dp"
android:elevation="12dp"
android:id="#+id/view2"
app:cardCornerRadius="40dp"
android:layout_centerHorizontal="true">
<ImageView
android:layout_height="80dp"
android:layout_width="match_parent"
android:id="#+id/imageView1"
android:src="#drawable/YOUR_IMAGE"
android:scaleType="centerCrop"/>
</android.support.v7.widget.CardView>
Adding Border to round ImageView - LATEST VERSION
Wrap it with another CardView slightly bigger than the inner one and set its background color to add a border to your round image. You can increase the size of the outer CardView to increase the thickness of the border.
<androidx.cardview.widget.CardView
android:layout_width="155dp"
android:layout_height="155dp"
app:cardCornerRadius="250dp"
app:cardBackgroundColor="#color/white">
<androidx.cardview.widget.CardView
android:layout_width="150dp"
android:layout_height="150dp"
app:cardCornerRadius="250dp"
android:layout_gravity="center">
<ImageView
android:layout_width="150dp"
android:layout_height="150dp"
android:src="#drawable/default_user"
android:scaleType="centerCrop"/>
</androidx.cardview.widget.CardView>
</androidx.cardview.widget.CardView>

You can make a simple circle with white border and transparent content with shape.
// res/drawable/circle.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:innerRadius="0dp"
android:shape="ring"
android:thicknessRatio="1.9"
android:useLevel="false" >
<solid android:color="#android:color/transparent" />
<stroke
android:width="10dp"
android:color="#android:color/white" />
</shape>
Then make a layerlist drawable and put it as background to your imageview.
// res/drawable/img.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="#drawable/circle"/>
<item android:drawable="#drawable/ic_launcher"/>
</layer-list>
and put it as background to your imageview.
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/img"/>
You'll have something like that.

With the Material Components Library Just use the ShapeableImageView.
Somethig like:
<com.google.android.material.imageview.ShapeableImageView
app:shapeAppearanceOverlay="#style/roundedImageViewRounded"
app:strokeColor="#color/....."
app:strokeWidth="1dp"
...
/>
with:
<style name="roundedImageViewRounded">
<item name="cornerFamily">rounded</item>
<item name="cornerSize">50%</item>
</style>
Note: it requires at least the version 1.2.0.
With jetpack compose you can apply the clip Modifier using a CircleShape:
Image(
painter = painterResource(R.drawable.xxxx),
contentDescription = "xxxx",
contentScale = ContentScale.Crop,
modifier = Modifier
.size(100.dp)
.clip(CircleShape)
.border(2.dp, Color.Blue, CircleShape)
)

I hope this will help you.

With the help of glide library and RoundedBitmapDrawableFactory class it's easy to achieve. You may need to create circular placeholder image.
Glide V4:
Glide.with(context).load(url).apply(RequestOptions.circleCropTransform()).into(imageView);
Glide V3:
Glide.with(context)
.load(imgUrl)
.asBitmap()
.placeholder(R.drawable.placeholder)
.error(R.drawable.placeholder)
.into(new BitmapImageViewTarget(imgProfilePicture) {
#Override
protected void setResource(Bitmap resource) {
RoundedBitmapDrawable drawable = RoundedBitmapDrawableFactory.create(context.getResources(),
Bitmap.createScaledBitmap(resource, 50, 50, false));
drawable.setCircular(true);
imgProfilePicture.setImageDrawable(drawable);
}
});
For Picasso RoundedTransformation, this is a really great solution that gives an additional option of rounding image at either top or bottom edge.

The above methods don't seem to work if you're using the src attribute. What I did is to put two image views inside a frame layout one above another like this:
<FrameLayout android:id="#+id/frame"
android:layout_width="40dp"
android:layout_height="40dp">
<ImageView android:id="#+id/pic"
android:layout_width="40dp"
android:layout_height="40dp"
android:src="#drawable/my_picture" />
<ImageView android:id="#+id/circle_crop"
android:layout_width="40dp"
android:layout_height="40dp"
android:src="#drawable/circle_crop" />
</FrameLayout>
Simply put a circular_crop.png in your drawable folder which is in the shape of your image dimensions (a square in my case) with a white background and a transparent circle in the center. You can use this image if you have want a square imageview.
Just download the picture above.

The following is one of the simplest ways to do it, use the following code:
Dependencies
dependencies {
...
compile 'de.hdodenhof:circleimageview:2.1.0' // use this or use the latest compile version. In case u get bug.
}
XML Code
<de.hdodenhof.circleimageview.CircleImageView
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/profile_image"
android:layout_width="96dp" // here u can adjust the width
android:layout_height="96dp" // here u can adjust the height
android:src="#drawable/profile" // here u can change the image
app:civ_border_width="2dp" // here u can adjust the border of the circle.
app:civ_border_color="#FF000000"/> // here u can adjust the border color

you don't need any third-party library.
you can use the ShapeableImageView in the material.

or this

You can simply use AndroidX ImageFilterView.
<androidx.constraintlayout.utils.widget.ImageFilterView
android:layout_width="48dp"
android:layout_height="48dp"
android:layout_marginStart="#dimen/margin_medium"
android:layout_marginBottom="#dimen/margin_medium"
android:background="#color/white"
android:padding="#dimen/margin_small"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:roundPercent="1"
app:srcCompat="#drawable/ic_gallery" />

You can simply use CardView without any external Library
<androidx.cardview.widget.CardView
android:id="#+id/roundCardView"
android:layout_width="40dp"
android:layout_height="40dp"
android:layout_centerHorizontal="true"
android:elevation="0dp"
app:cardCornerRadius="20dp">
<ImageView
android:layout_width="40dp"
android:layout_height="40dp"
android:src="#drawable/profile" />
</androidx.cardview.widget.CardView>

This will do the trick:
rectangle.xml
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#android:color/transparent" />
<padding android:bottom="-14dp" android:left="-14dp" android:right="-14dp" android:top="-14dp" />
</shape>
circle.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:innerRadius="0dp"
android:shape="oval"
android:useLevel="false" >
<solid android:color="#android:color/transparent" />
<stroke
android:width="15dp"
android:color="#color/verification_contact_background" />
</shape>
profile_image.xml ( The layerlist )
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="#drawable/rectangle" />
<item android:drawable="#drawable/circle"/>
</layer-list>
Your layout
<ImageView
android:id="#+id/profile_image"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/default_org"
android:src="#drawable/profile_image"/>

Posting this answer for future reference. You can use ShapeableImageView available in com.google.android.material:material.
<com.google.android.material.imageview.ShapeableImageView
android:id="#+id/img_launcher_icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_margin="5dp"
android:adjustViewBounds="true"
android:background="#android:color/transparent"
android:elevation="5dp"
android:maxWidth="50dp"
android:maxHeight="50dp"
android:scaleType="fitXY"
android:src="#mipmap/ic_launcher"
app:shapeAppearance="?attr/actionButtonStyle"
app:shapeAppearanceOverlay="#style/imageViewRounded"
app:strokeColor="#android:color/white" />
Add imageViewRounded style in your styles.xml
<style name="imageViewRounded">
<item name="cornerFamily">rounded</item>
<item name="cornerSize">51%</item>
</style>
You can add material design dependency if not added.
implementation 'com.google.android.material:material:1.4.0'
Design looks like

Best Solution courtesy https://www.youtube.com/watch?v=0MHoNU7ytaw
the width and height of the card view determine the size of the images it contains set up is as follows:
Add Dependency to Gradle(Module)
Add the xml code to activity.xml or fragment.xml file
implementation 'androidx.cardview:cardview:1.0.0'
<androidx.cardview.widget.CardView
android:layout_width="300dp"
android:layout_height="270dp"
android:layout_gravity="center"
app:cardCornerRadius="150dp"
app:cardBackgroundColor="#color/trans"
>
<ImageView
android:id="#+id/resultImage"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/congrats"
android:layout_gravity="center">
</ImageView>
</androidx.cardview.widget.CardView>```

Update 2021: Using Glide v4 CircleCrop see https://bumptech.github.io/glide/doc/generatedapi.html
implementation 'com.github.bumptech.glide:glide:4.11.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.11.0'
XML
<ImageView
android:id="#+id/vinyl"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:ignore="ContentDescription" />
In Code
Glide.with(this)
.load("https://images.pexels.com/photos/3828241/pexels-photo-3828241.jpeg")
.transform(CircleCrop())
.into(rootView.findViewById<ImageView>(R.id.vinyl))

I use shape = "oval" instead of the "ring" below. It has worked for me. To keep the image within bounds, I use <padding> and set <adjustViewBounds> to true in my <ImageView>. I have tried with images of size between 50 x 50 px upto 200x200 px .

#Jyotman Singh, answer is very good (for solid backgrounds), so I would like to enhance it by sharing vector drawable that can be re-colored for your needs, also it is convenient since vector one-piece shape is well scalable.
This is the rectangle-circle shape (#drawable/shape_round_profile_pic):
<?xml version="1.0" encoding="utf-8"?>
<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:viewportWidth="284"
android:viewportHeight="284"
android:width="284dp"
android:height="284dp">
<path
android:pathData="M0 142L0 0l142 0 142 0 0 142 0 142 -142 0 -142 0zm165 137.34231c26.06742 -4.1212 52.67405 -17.543 72.66855 -36.65787 11.82805 -11.30768 20.55487 -22.85153 27.7633 -36.72531C290.23789 158.21592 285.62874 101.14121 253.48951 58.078079 217.58149 9.9651706 154.68849 -10.125717 98.348685 8.5190299 48.695824 24.95084 12.527764 67.047123 3.437787 118.98655 1.4806194 130.16966 1.511302 152.96723 3.4990422 164.5 12.168375 214.79902 47.646316 256.70775 96 273.76783c21.72002 7.66322 44.26673 9.48476 69 5.57448z"
android:fillColor="#ffffff" /> // you can change frame color
</vector>
Usage is the same:
<FrameLayout
android:layout_width="70dp"
android:layout_height="70dp">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/YOUR_PICTURE" />
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/shape_round_profile_pic"/>
</FrameLayout>

Just use these lines of code and you are done :
<de.hdodenhof.circleimageview.CircleImageView
xmlns:app="http://schemas.android.com/apk/res-auto"
android:clickable="true"
app:civ_border_width="3dp"
app:civ_border_color="#FFFFFFFF"
android:id="#+id/profile"
android:layout_width="200dp"
android:layout_height="200dp"
android:layout_below="#+id/header_cover_image"
android:layout_centerHorizontal="true"
android:layout_marginTop="-130dp"
android:elevation="5dp"
android:padding="20dp"
android:scaleType="centerCrop"
android:src="#drawable/profilemain" />
Don't forget to import :
import de.hdodenhof.circleimageview.CircleImageView;
Add this library in build.gradle :
compile 'de.hdodenhof:circleimageview:2.1.0'

If you use Material Design in your app then use this
<com.google.android.material.card.MaterialCardView
android:layout_width="75dp"
android:layout_height="75dp"
app:cardCornerRadius="50dp"
app:strokeWidth="1dp"
app:strokeColor="#color/black">
<ImageView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/circular_image"
android:scaleType="fitCenter"
android:src="#drawable/your_img" />
</com.google.android.material.card.MaterialCardView>

I did it like that, I used my background color in my vector image
ic_bg_picture.xml
<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:width="100dp"
android:height="100dp"
android:viewportWidth="100"
android:viewportHeight="100">
<path
android:pathData="M100.6,95.5c0,-0.4 -0.1,-0.7 0,-1.1c-0.2,-0.7 -0.2,-1.4 -0.1,-2.1c0,-0.1 0,-0.2 0,-0.3c-0.1,-0.6 -0.1,-1.2 0,-1.8c-1,-1.3 -0.3,-2.9 -0.3,-4.3c-0.1,-28.7 -0.1,-57.3 -0.1,-86C68,-0.1 35.9,-0.1 3.8,-0.2C0.7,-0.2 0,0.5 0,3.6c0.1,32.1 0.1,64.2 0.1,96.2c31,0 62,-0.1 92.9,0.1c3.6,0 6.3,-0.2 7.5,-3.2C100.5,96.4 100.5,95.9 100.6,95.5zM46.3,95.2C26.4,94 2,74.4 3.8,46.8C5.1,27.2 24.4,2.7 52.6,4.6c20.2,1.4 43,21.3 41.5,45.1C96.1,72.4 73,96.8 46.3,95.2z"
android:fillColor="#6200EE"/>
</vector>
in my case I created a vector and changed the android:fillColor="#6200EE"
by the color of my background
<ImageView
android:id="#+id/iv_profile_image"
android:layout_width="100dp"
android:layout_height="100dp"
android:contentDescription="#string/app_name"
app:srcCompat="#color/colorPrimaryDark" />
<ImageView
android:id="#+id/container_profile_image"
android:layout_width="100dp"
android:layout_height="100dp"
android:contentDescription="#string/app_name"
app:srcCompat="#drawable/ic_bg_picture"/>

Another method without using any library is using ImageFilterView and setting round percentage to the view will make the circle round
app:roundPercent="1"
<androidx.constraintlayout.utils.widget.ImageFilterView
android:id="#+id/ivProfile"
android:layout_width="150dp"
android:layout_height="150dp"
android:src="#drawable/custom_button_1"
app:roundPercent="1"
android:scaleType="fitXY"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintBottom_toTopOf="#+id/etName"/>

Try this.
public class RoundedImageView extends android.support.v7.widget.AppCompatImageView {

int circleCenter = viewWidth / 2;
canvas.drawCircle(circleCenter + borderWidth, circleCenter + borderWidth, circleCenter + borderWidth - 4.0f, paintBorder);
canvas.drawCircle(circleCenter + borderWidth, circleCenter + borderWidth, circleCenter - 4.0f, paint);
}

and use this ImageView in layout like:

android:id="#+id/iv_profileImage"
android:layout_width="70dp"
android:layout_height="70dp"
android:layout_centerHorizontal="true"

This Class is Custom Circular Imageview with shadow, Stroke,saturation and using this Custom Circular ImageView you can make your image in Circular Shape with Radius. Guys for Circular Shadow ImageView No need Github this class is enough.
Adding CircularImageView to your layout

Actually, you can use what Google provides via the support library RoundedBitmapDrawableFactory class (here and here), instead of using a third party library :
Gradle:
implementation 'androidx.appcompat:appcompat:1.0.0-beta01'
MainActivity.kt
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val originalDrawable = ContextCompat.getDrawable(this, R.drawable.avatar_1)!!
val bitmap = convertDrawableToBitmap(originalDrawable)
val drawable = RoundedBitmapDrawableFactory.create(resources, bitmap)
drawable.setAntiAlias(true)
drawable.cornerRadius = Math.max(bitmap.width, bitmap.height) / 2.0f
avatarImageView.setImageDrawable(drawable)
}
companion object {
#JvmStatic
fun convertDrawableToBitmap(drawable: Drawable): Bitmap {
if (drawable is BitmapDrawable)
return drawable.bitmap
// We ask for the bounds if they have been set as they would be most
// correct, then we check we are > 0
val bounds = drawable.bounds
val width = if (!bounds.isEmpty) bounds.width() else drawable.intrinsicWidth
val height = if (!bounds.isEmpty) bounds.height() else drawable.intrinsicHeight
// Now we check we are > 0
val bitmap = Bitmap.createBitmap(if (width <= 0) 1 else width, if (height <= 0) 1 else height,
Bitmap.Config.ARGB_8888)
val canvas = Canvas(bitmap)
drawable.setBounds(0, 0, canvas.width, canvas.height)
drawable.draw(canvas)
return bitmap
}
}
}

The result:
And, suppose you want to add a border on top of it, you can use this for example:
stroke_drawable.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval">
<stroke
android:width="4dp" android:color="#android:color/black"/>
</shape>
And add android:foreground="#drawable/stroke_drawable" to the ImageView in the layout XML file, and you get this :
I'm not sure how to add shadow (that will work on older Android versions), though. Using FloatingActionButton (from the "com.google.android.material:material" dependency), I failed to make the bitmap fill the FAB itself. Using it instead could be even better if it worked.
EDIT: if you wish to add shadow of elevation (available from API 21), you can change a bit what I wrote:
Inside the layout XML file:
<androidx.appcompat.widget.AppCompatImageView android:padding="4dp"
android:id="#+id/avatarImageView" android:layout_width="100dp" android:layout_height="100dp" android:elevation="8dp"
android:layout_gravity="center" android:background="#drawable/stroke_drawable" tools:srcCompat="#drawable/avatar_1"/>
CircularShadowViewOutlineProvider.kt
#TargetApi(Build.VERSION_CODES.LOLLIPOP)
class CircularShadowViewOutlineProvider : ViewOutlineProvider() {
override fun getOutline(view: View, outline: Outline) {
val size = Math.max(view.width, view.height)
outline.setRoundRect(0, 0, size, size, size / 2f)
}
}
In code:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
avatarImageView.outlineProvider = CircularShadowViewOutlineProvider()
Result:

I have a simple solution.
Create a new Image asset by right clicking your package name and selecting New->Image asset.
Enter name (any name) and path (location of image in your system).
Then click Next and Finish.
If you enter name of image as 'img', a round image with the name 'img_round' is created automatically in mipmap folder.
Then, do this :
<ImageView
android:layout_width="100dp"
android:layout_height="100dp"
android:src="#mipmap/img_round"/>
Your preview may still show a rectangular image. But if you run the app on your device, it will be round.

Create a CustomImageview then simply override its onDraw() method follows:
#Override
protected void onDraw(Canvas canvas) {
float radius = this.getHeight()/2;
Path path = new Path();
RectF rect = new RectF(0, 0, this.getWidth(), this.getHeight());
path.addRoundRect(rect, radius, radius, Path.Direction.CW);
canvas.clipPath(path);
super.onDraw(canvas);
}
In case you want the code for the custom widget as well:-
CircularImageView.java
import android.content.Context;
import android.content.res.TypedArray;
import android.graphics.Canvas;
import android.graphics.Path;
import android.graphics.RectF;
import android.graphics.drawable.Drawable;
import android.util.AttributeSet;
import android.widget.ImageView;
import androidx.annotation.Nullable;
public class CircularImageView extends ImageView {
private Drawable image;
public CircularImageView(Context context) {
super(context);
init(null, 0);
}
public CircularImageView(Context context, #Nullable AttributeSet attrs) {
super(context, attrs);
init(attrs, 0);
}
public CircularImageView(Context context, #Nullable AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
init(attrs, defStyleAttr);
}
#Override
protected void onDraw(Canvas canvas) {
float radius = this.getHeight()/2;
Path path = new Path();
RectF rect = new RectF(0, 0, this.getWidth(), this.getHeight());
path.addRoundRect(rect, radius, radius, Path.Direction.CW);
canvas.clipPath(path);
super.onDraw(canvas);
}
private void init(AttributeSet attrs, int defStyle) {
TypedArray a = Utils.CONTEXT.getTheme().obtainStyledAttributes(attrs, R.styleable.CircularImageView, 0, 0);
try {
image = a.getDrawable(R.styleable.CircularImageView_src);
} finally {
a.recycle();
}
this.setImageDrawable(image);
}
}
Also, add the following code to your res/attrs.xml to create the required attribute:-
<declare-styleable name="CircularImageView">
<attr name="src" format="reference" />
</declare-styleable>

if you want to set edit icon on to circle imageview than put this below code.
<FrameLayout
android:layout_width="#dimen/_100sdp"
android:layout_height="#dimen/_100sdp"
android:layout_gravity="center"
android:layout_marginTop="10dp">
<de.hdodenhof.circleimageview.CircleImageView
android:id="#+id/profilePic"
android:layout_width="#dimen/_100sdp"
android:layout_height="#dimen/_100sdp"
android:layout_gravity="bottom|center_horizontal"
android:src="#drawable/ic_upload" />
<de.hdodenhof.circleimageview.CircleImageView
android:id="#+id/iv_camera"
android:layout_width="#dimen/_30sdp"
android:layout_height="#dimen/_30sdp"
android:layout_gravity="top|right"
android:src="#drawable/edit"/>
</FrameLayout>

if you'd rather cut the image to display in circular, here you go
public static Bitmap getCircularBitmap(Bitmap bitmap) {
Bitmap output;
if (bitmap.getWidth() > bitmap.getHeight()) {
output = Bitmap.createBitmap(bitmap.getHeight(), bitmap.getHeight(), Bitmap.Config.ARGB_8888);
} else {
output = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getWidth(), Bitmap.Config.ARGB_8888);
}
Canvas canvas = new Canvas(output);
final int color = 0xff424242;
final Paint paint = new Paint();
final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());
float r = 0;
if (bitmap.getWidth() > bitmap.getHeight()) {
r = bitmap.getHeight() / 2;
} else {
r = bitmap.getWidth() / 2;
}
paint.setAntiAlias(true);
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(color);
canvas.drawCircle(r, r, r, paint);
paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
canvas.drawBitmap(bitmap, rect, rect, paint);
return output;
}

Another idea is to use clipToOutline property of an ImageView.
Here is an example layout:
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Simple view to draw borders for an image,
borders will be rounded because of the oval-shaped background. -->
<View
android:id="#+id/v_border"
android:layout_width="50dp"
android:layout_height="50dp"
android:background="#drawable/shape_border"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<!-- Image itself: fits the border view,
a margin serves as a border width;
the key point here - is a background shape which will clip the view to its forms. -->
<ImageView
android:id="#+id/iv_image"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_margin="4dp"
android:background="#drawable/shape_oval"
android:src="#mipmap/ic_launcher"
app:layout_constraintBottom_toBottomOf="#+id/v_border"
app:layout_constraintEnd_toEndOf="#+id/v_border"
app:layout_constraintStart_toStartOf="#+id/v_border"
app:layout_constraintTop_toTopOf="#+id/v_border" />
</androidx.constraintlayout.widget.ConstraintLayout>
And here are our shape_border drawable:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval">
<solid android:color="#FF00FF" />
</shape>
And shape_oval drawable:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval" />
The only thing you should do in the code - is to enable clipToOutline property:
binding.ivImage.clipToOutline = true
And of course you can avoid even this line of the code with some BindingAdapter.

This is a relatively old question, but you can just make a circle border in the drawable folder (let's assume the xml file will be called circle_border)
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid android:color="#android:color/transparent" />
<!-- If you want a padding -->
<padding android:top="4dp" android:left="4dp" android:right="4dp" android:bottom="4dp" />
<!-- If you want the circle border to have a color -->
<strong android:width="1dp" android:color="#FFFFFF" />
</shape>
Then you can use it as the background of the ImageView
<ImageView
android:background="#drawable/circle_border"
<!-- other attributes here -->
/>

just use this simple code:
First add dependency :
implementation 'de.hdodenhof:circleimageview:2.2.0'
then add in xml layout the following code:-
<de.hdodenhof.circleimageview.CircleImageView xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/Imgshaligram"
android:layout_width="96dp"
android:layout_height="96dp"
android:src="#drawable/shaligram"
app:civ_border_color="#d1b1b1"
android:foregroundGravity="center"/>

Is there a way to implement rounded corners to a Mapfragment?

I want to give the map a nice looking rounded corners as the two boxes below it have.
I can't do it with the map fragment it self because there is not a background property to a
fragment.
setting the map inside a layout and setting it background to a rounded shape didn't help me
as well and this is the result:
I could merge the map but this would make it smaller and i would like to avoid it.
EDIT:
#Ryan this is the new result #2:
I guess this is not bad, no even close to the corners on the other boxes,
but still not bad with a little more work a could get somewhere close i just dont have a normal image editor.
but one thing that still bothers me now is the separation between the "Location" Textview and the map it's self. could i painted the patch in other way so that there was now distance? this is how i did it:
Well I have finally figured this out:
this is what i used for the patch:
Thanks.

I know it's an old post, but you can try using Cards like so:
<android.support.v7.widget.CardView
android:layout_width="300dp"
android:layout_height="350dp"
android:layout_gravity="center_horizontal|center_vertical"
android:layout_marginLeft="10dp"
android:layout_marginRight="10dp"
android:layout_marginTop="20dp"
app:cardCornerRadius="12dp"
app:cardElevation="12dp">
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</android.support.v7.widget.CardView>

I haven't tried this, but I'd put a view with rounded corners and a transparent middle on top of the mapView / mapFragment.
That is, put the mapFragment and the rounded corner view in a FrameLayout with both filling the FrameLayout, then make the middle of the rounded corner view transparent.
For further clarification, you could do it in a layout as follows:-
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<fragment
xmlns:map="http://schemas.android.com/apk/res-auto"
android:id="#+id/mapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.MapFragment" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/rounded_background"
android:orientation="vertical" >
</LinearLayout>
</FrameLayout>
The rounded_background is a 9-patch with rounded corners and a transparent middle. E.g.
Hope that helps,
Ryan

The easiest way is to wrap the map fragment inside a FrameLayout along with an ImageView. The Imageview would display a rounded rectangle on top of the map fragment. In its simplest form you will see the map fragment inside the rounded rectangle with its corners sticking out of the rounded rectangle because the map view itself is not rounded. To overcome this visual oddity simply apply a layout_margin value on map fragment. The value should be equal to the rectangle's border width.
<FrameLayout
android:id="#+id/map_container"
android:layout_width="wrap_content"
android:layout_height="340dp" >
<fragment
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="3dp"
android:name="com.google.android.gms.maps.SupportMapFragment"/>
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/map_bg_box" />
</FrameLayout>
The rectangle drawable is defined as an xml shape as below
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke android:width="3dp"
android:color="#ff000000" />
<corners android:bottomRightRadius="7dp" android:bottomLeftRadius="7dp"
android:topLeftRadius="7dp" android:topRightRadius="7dp"/>
</shape>
Notice the stroke width of the rectangle is 3dp that is exactly the same value we applied to the layout_margin property of the map fragment. The result is a nicely round cornered map fragment as shown in the screenshot below

Wrap the map fragment in this layout:

mPathCornersBorder.reset();
mPathCornersBorder.addRoundRect(rectBorder, mCornerRadius - mBorderHalf, mCornerRadius -
mBorderHalf, Path.Direction.CW);
mPathCornersBorder.close();
}
}
In layout will be like this:
<com.example.yourpackage.RoundedLayout
android:id="#+id/maplayout"
android:layout_width="match_parent"
android:layout_height="200dp"
android:layout_margin="20dp">
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="200dp"
tools:context="com.example.yourpackage.MapsMarkerActivity"/>
</com.example.yourpackage.RoundedLayout>
In code can be like this for a round shape with border:
RoundedLayout rl = (RoundedLayout) findViewById(R.id.maplayout);
rl.setShapeCircle(true);
rl.showBorder(true);
rl.setBorderWidth(2);
This layout can be used to shape any view.
It's incredible how google is incapable of making competent (usable) complete demos for it's android API.

For other people looking into this, I just tackled this using GoogleMap.snapshot and manipulating the bitmap result with this stack over flow answer:
How to make an ImageView with rounded corners?
Mind you this is only valid if you are going to have a static map that is not going to be interacted with.
Make sure you take the snap shot after the map is loaded.
I updated the image view helper code to draw with path to support rounding only some corners. ie. If you want to round only 2 of the corners.
You just need the path round rect function that takes a float[]
I show a progress bar until I get a callback from GoogleMap loaded listener than I take the snapshot.
If you take your snapshot too early you will get can't create bitmap with 0 width and height error.
Hope this helps someone looking for rounded corners or other weird shape in static map snapshot.

If you are only trying to target API 21 (Lollipop) and higher
This is the easiest way possible.
parentView.setClipToOutline(true);

Unable to get exact circle shape when using card view - android

<androidx.cardview.widget.CardView android:layout_width="60dp" android:layout_marginStart="150dp" app:cardCornerRadius="360dp" android:layout_height="60dp">

I came up with simple Solution of Using a Drawable and it looks amazing! Get Drawable here https://drive.google.com/drive/folders/0B4Vo_ku-aIKzUFFnUjYxYVRLaGc?resourcekey=0-RiH8lUO0i1kwnZsqquqjnQ&usp=sharing

add this line to the CardView which sets the cardCornerRadius to the Circle diameter. app:cardCornerRadius="360dp"

Yes, I have achieved it by reducing half of the CardCornerRadius to its View's Height.
