Android: Smooth background colour repeating with boarder

i did the smooth background colour repeating for TextView like below
final Handler mHandler2 = new Handler();
final Runnable mUpdateResults2 = new Runnable() {
public void run() {
ObjectAnimator colorFade = ObjectAnimator.ofObject(tvGoLive, "backgroundColor", new ArgbEvaluator(), Color.parseColor("#FFFFFF"), Color.parseColor("#000000"));
colorFade.setDuration(1000);
colorFade.start();
}
};
final Runnable mUpdateResults3 = new Runnable() {
public void run() {
ObjectAnimator colorFade = ObjectAnimator.ofObject(tvGoLive, "backgroundColor", new ArgbEvaluator(), Color.parseColor("#000000"), Color.parseColor("#FFFFFF"));
colorFade.setDuration(1000);
colorFade.start();
}
};
int delay2 = 1000;
int period2 = 1000;
Timer timer2 = new Timer();
timer2.scheduleAtFixedRate(new TimerTask() {
int rotation = 1;
public void run() {
if(rotation == 1){
mHandler2.post(mUpdateResults2);
rotation = 2;
}else if (rotation == 2) {
mHandler2.post(mUpdateResults3);
rotation = 1;
}
}
}, delay2, period2);
Now i need to set the boarder for this TextView programmatically. For this requirement i tried some codes in SO and Google, but i didn't get the boarder for text view. So, any one give me the code for setting boarder with smooth background colour repeating

Finally i got the solution
1. Drawable xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape android:shape="rectangle" >
<solid android:color="#0000FF" />
</shape>
</item>
</layer-list>
If you need boarder, then add <corners android:radius="5dp" /> inside shape of drawable xml
2. Layout
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="3dp"
android:background="#drawable/btn_radious" >
<TextView
android:id="#+id/club_detail_go_live_tv"
android:layout_width="wrap_content"
android:layout_height="30dp"
android:layout_centerInParent="true"
android:background="#FFFFFF"
android:drawableLeft="#drawable/icon_go_live_small"
android:ellipsize="end"
android:gravity="center"
android:maxLength="30"
android:padding="5dp"
android:text="#string/app_name"
android:textColor="#000000" />
</RelativeLayout>
3. Code
Code as above question

Button Layout with Profile Picture Alignment

I want to create buttons that look like in the picture. Inside the circle (which is transparent in the png) I want to place the profile picture of players. There should also be text on the blue bar.
I've got it working but it just seems way too complicated. I think it is easier to understand what I have done without giving code but if you need it I can add it. Here is the layout:
RelativeLayout
LinearLayout (horizontal orientation)
Empty view with weight 0.7
Profile Picture with weight 0.2
Empty view with weight 0.1
the overlay picture that I posted below
LinearLayout (horizontal orientation)
RelativeLayout with weight 0.7 (space where all the text can go)
empty view with weigh 0.3
By the way: to the right of the circle, the png isn't transparent but white!
This works well but there must be a better way! All these empty views just to align the picture to the right position is kind of ugly. And the fact that the overlay picture must go inbetween the profile picture and the text makes it even uglier.
I'd prefer to do it without a png as overlay but with simple shapes (so that it looks good on every screen) but I wouldn't know how to do that. Would you recommend that? And if yes, how could that be done?
Or do you have an idea how to improve the xml layout or how to do it otherwise.
Thanks very much

You can do it without any image:
Layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="60dp"
android:weightSum="1.0">
<TextView
android:layout_weight="0.7"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:text="New Text"
android:id="#+id/textView"
android:background="#0073ff"/>
<ImageView
android:layout_weight="0.2"
android:layout_width="0dp"
android:layout_height="match_parent"
android:background="#drawable/half_round_drawable"
android:src="#drawable/profile"/>
</LinearLayout>
</LinearLayout>
half_round_drawable:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape android:shape="oval">
<corners android:radius="16dp" />
<solid android:color="#0073ff" />
</shape>
</item>
<item
android:bottom="0dp"
android:right="32dp"> <!-- radius *2 -->
<shape>
<solid android:color="#0073ff" />
</shape>
</item>
</layer-list>
To make the profile-image round you should use something like this:
How to create a circular ImageView in Android?

You can use a simple LinearLayout if you confine the background image to the profile area at the right side. You can define the content area in the image itself if you use a nine-patch drawable, as follows:
Extract the profile portion from your background image file.
Create a nine patch drawable from it, defining all the area as stretchable (left and top border lines), and the empty circle as the content area (right and bottom lines).
Since you should ideally have the image at the foreground layer to ensure that the photo isn't drawn outside of the circle, you can use a FrameLayout with a foreground drawable to contain your profile photo's ImageView. There would also need to be another dummy child view to work around a bug in FrameLayout that causes a single child with match_parent dimensions to be layout incorrectly.
This is how the layout should look like at the end:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:id="#+id/text"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:background="#00f" />
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:foreground="#drawable/profile_bg">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent" />
<ImageView
android:id="#+id/photo"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</FrameLayout>
</LinearLayout>

How to show notification count on ActionBar Menu items using Appcompat v21

Actually I am developing an application in android and I want to show the total no. of unread emails on the Action Bar Menu Item (like flipkart and all other applications already have) using latest Appcompat V21. I tried a code which I have found here but its not working with AppCompat V21.
Please help me if you can!
Posting the same code here:

A 64x64 pixel image with 10 pixel wide paddings from all sides. You are supposed to have 8 pixel wide paddings, but I find most default items being slightly smaller than that. Of course, you'll want to use different sizes for different densities.

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
Screenshot:

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

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

and use this ImageView in layout like:

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"/>

How to display an ImageView progressively down from top to bottom

is there a way to display an ImageView progressively from top to down,
like this:
Sorry for the crappy animation.

I'm not very familiar with android animations, but one(a little hackish) way is to wrap the image in a ClipDrawable and animate its level value. For example:
<ImageView
android:id="#+id/imageView1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/clip_source" />
Where clip_source is a drawable:
<?xml version="1.0" encoding="utf-8"?>
<clip xmlns:android="http://schemas.android.com/apk/res/android"
android:clipOrientation="vertical"
android:drawable="#drawable/your_own_drawable"
android:gravity="bottom" />
Then in code you would have:
// a field in your class
private int mLevel = 0;
ImageView img = (ImageView) findViewById(R.id.imageView1);
mImageDrawable = (ClipDrawable) img.getDrawable();
mImageDrawable.setLevel(0);
mHandler.post(animateImage);
The animateImage is a Runnable object:
private Runnable animateImage = new Runnable() {
#Override
public void run() {
doTheAnimation();
}
};
and the doTheAnimation method:
private void doTheAnimation() {
mLevel += 1000;
mImageDrawable.setLevel(mLevel);
if (mLevel <= 10000) {
mHandler.postDelayed(animateImage, 50);
} else {
mHandler.removeCallbacks(animateImage);
}
}
