I am using pint it button in my application but it is in rectangle shape. How can i change in round button with custom background. How can i set background of pint it button.
<com.pinterest.pinit.PinItButton
android:id="#+id/pin_bt"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="5dp" />
you can use rounded corner imageview code for xml
<in.appera.sachin.ImageViewRounded
android:id="#+id/ivProfile"
android:layout_width="100dp"
android:layout_height="100dp"
android:layout_marginTop="30dp"
/>

I want to fetch the profile image from google play games which is working with this method:
public void loadPlayerImage() {
ImageView playerImage=(ImageView) findViewById(R.id.playerImage);
Player me = Games.Players.getCurrentPlayer(mGoogleApiClient);
ImageManager mgr = ImageManager.create(this);
mgr.loadImage(playerImage, me.getIconImageUri());
}
But when I try to make it circled with this library it does not show the image:
https://github.com/hdodenhof/CircleImageView
How can I circle the profile image?
You can use this code as a helper within an ImageHelper class and extend it to pass in the amount of feathering you need for a given image.
public static Bitmap getRoundedCornerBitmap(Bitmap bitmap) {
Bitmap output = Bitmap.createBitmap(bitmap.getWidth(),
bitmap.getHeight(), 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());
final RectF rectF = new RectF(rect);
final float roundPx = 12;
paint.setAntiAlias(true);
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(color);
canvas.drawRoundRect(rectF, roundPx, roundPx, paint);
paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
canvas.drawBitmap(bitmap, rect, rect, paint);
return output;
}

How to make an ImageView with rounded corners?
How to create a circular ImageView in Android?
When a FloatingActionButton is anchored to a CollapsingToolbarLayout, it disappears when you scroll up, reappears when you scroll down after a certain point. I was wondering if you can do that with any type of view. In my app, I'm trying to anchor an ImageView to the CollapsingToolbarLayout but it won't disappear like the FloatingActionButton. Here's the XML code.
<android.support.design.widget.AppBarLayout
android:id="#+id/bar"
android:layout_width="match_parent"
android:layout_height="252dp"
android:fitsSystemWindows="true">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:contentScrim="?attr/colorPrimary"
app:expandedTitleMarginBottom="32dp"
app:expandedTitleMarginEnd="64dp"
app:expandedTitleMarginStart="48dp"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<ImageView
android:id="#+id/header"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/random"
android:fitsSystemWindows="true"
android:scaleType="centerCrop"
app:layout_collapseMode="parallax" />
<android.support.v7.widget.Toolbar
android:id="#+id/anim_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin"

android:id="#+id/scrollableview"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
<com.example.sudarshan.testapp.MLRoundedImageView

</android.support.design.widget.CoordinatorLayout>
The ImageView gets anchored but it does not disappear and reappear like the FAB does.
This behaviour of disappearing and appearing of View is only associated with FAB(FloatingActionButton).
You should have a look on the source code of class FloatingActionButton.
Here is the method in Behavior class , inner class of FloatingActionButtonwhich is responsible for the behaviour.
#Override
public boolean onDependentViewChanged(CoordinatorLayout parent, FloatingActionButton child,
View dependency) {
if (dependency instanceof Snackbar.SnackbarLayout) {
updateFabTranslationForSnackbar(parent, child, dependency);
} else if (dependency instanceof AppBarLayout) {
// If we're depending on an AppBarLayout we will show/hide it automatically
// if the FAB is anchored to the AppBarLayout
updateFabVisibility(parent, (AppBarLayout) dependency, child);
}
return false;
}
Edit
You can extend the class FloatingActionButton to achieve what I think you need.
I have extended as follows-
/**
* Sked Series, All rights Reserved
* Created by Sanjeet on 06-Jan-16.
*/
public class FloatingActionImageView extends FloatingActionButton {
public FloatingActionImageView(Context context) {
super(context);
}
public FloatingActionImageView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public FloatingActionImageView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
public static Bitmap getCroppedBitmap(Bitmap bmp, int radius) {
Bitmap sBmp;
if (bmp.getWidth() != radius || bmp.getHeight() != radius) {
float smallest = Math.min(bmp.getWidth(), bmp.getHeight());
float factor = smallest / radius;
sBmp = Bitmap.createScaledBitmap(bmp, (int) (bmp.getWidth() / factor), (int) (bmp.getHeight() / factor), false);
} else {
sBmp = bmp;
}
Bitmap output = Bitmap.createBitmap(radius, radius,
Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(output);
final Paint paint = new Paint();
final Rect rect = new Rect(0, 0, radius + 5, radius + 5);
paint.setAntiAlias(true);
paint.setFilterBitmap(true);
paint.setDither(true);
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(Color.parseColor("#BAB399"));
canvas.drawCircle(radius / 2,
radius / 2, radius / 2, paint);
paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
canvas.drawBitmap(sBmp, rect, rect, paint);
return output;
}
#Override
protected void onDraw(#NonNull Canvas canvas) {
Drawable drawable = getDrawable();
if (drawable == null) {
return;
}
if (getWidth() == 0 || getHeight() == 0) {
return;
}
Bitmap b = ((BitmapDrawable) drawable).getBitmap();
Bitmap bitmap = null;
if (b != null) {
bitmap = b.copy(Bitmap.Config.ARGB_8888, true);
} else {
BitmapDrawable bitmapDrawable = null;
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) {
bitmapDrawable = ((BitmapDrawable) getResources().getDrawable(com.sked.dd.R.drawable.ic_menu_gallery, null));
} else {
bitmapDrawable = ((BitmapDrawable) getResources().getDrawable(com.sked.dd.R.drawable.ic_menu_gallery));
}
if (bitmapDrawable != null) {
bitmap = bitmapDrawable.getBitmap();
}
}
int w = getWidth();
Bitmap roundBitmap = getCroppedBitmap(bitmap, w);
canvas.drawBitmap(roundBitmap, 0, 0, null);
}
}
And here is the output -

canvas.drawBitmap(bitmap, rect, rect, paint);

}
}
Then call it in xml
<yourPackageName.RoundedImage
android:id="#+id/singleCompLogo"
android:layout_width="70dp"
android:layout_height="70dp"
android:layout_margin="16dp"
android:clickable="true"

app:layout_anchor="#id/app_bar_layout"
app:civ_border_width="2dp"
app:layout_anchorGravity="bottom|left|start"
android:src="#mipmap/image" />
Replace yourPackageName with YOUR PACKAGE NAME
Add app:layout_scrollFlags="scroll|enterAlways" in your Toolbar xml
<android.support.v7.widget.Toolbar
android:id="#+id/anim_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" >

I want to display my images in listview where the imageview is rounded, i serached in the net and in stackoverflow i just found that they use bitmap or i dont like to use it because i'm getting my information from webservice. is there any method or exemple to display it in this way.
this is how i display my images rectangle border
mLoader.DisplayImage(mylink + ArrayListComment.get(position).getImage(), holder.imageView);
}
if(ArrayListComment.get(position).getImage().contains(".png") {
mLoader.DisplayImage(ArrayListComment.get(position).getImage(), holder.imageView);
}
For rounded ImageView use RoundedImageView.
For display image from url use Picasso.
Create a new rounded.xml under drawable
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item>
<shape android:shape="rectangle" >
<stroke
android:width="10dp"
android:color="#FFffffff" />
<solid android:color="#00000000" />
<padding
android:bottom="0dp"
android:left="0dp"
android:right="0dp"
android:top="0dp" />
</shape>
</item>
<item>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<stroke
android:width="10dp"
android:color="#FFffffff" />
<solid android:color="#00000000" />
<corners android:radius="30dp" />
</shape>
</item>
</layer-list>
and use it in your xml image view like this:
android:src="#drawable/rounded" and set the image background as you want it to be, it will be in a rounded shape
I hope this will help

}
You will have to customise your image loader.
EDIT:
If you dont want to create a copy of a bitmap, you can use a bitmap shader.
See this blog,
http://www.curious-creature.com/2012/12/11/android-recipe-1-image-with-rounded-corners/
See the RoundedImageView for implementation.

may it work for you
i have a rectangular image that i convert to a circle, then i set that image to the imageview. however i get a black square around the circular image. I need it to match the rest of the layout which is white.Can anyone explain why?
the layout below is part of a much larger layout that is used as the layout for the listview. I tried this code alone in a different app and it worked fine. The default color of the xml layout was white in that app so maybe it is still drawing the square but i just cant see it? The default color of the xml in my original app is black. could that be causing the problem?
here is part of the layout
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#fff"
android:orientation="horizontal" >
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"

How to make an ImageView with rounded corners?
(58 answers)
Closed 9 years ago.
How could I create a rounded ImageView in Android?
I have tried the following code, but it's not working fine.
Code:
Bitmap circleBitmap = Bitmap.createBitmap(bitmap.getWidth(), bitmap.getHeight(), Bitmap.Config.ARGB_8888);
BitmapShader shader = new BitmapShader (bitmap, TileMode.CLAMP, TileMode.CLAMP);
Paint paint = new Paint();
paint.setShader(shader);
Canvas c = new Canvas(circleBitmap);
c.drawCircle(bitmap.getWidth()/2, bitmap.getHeight()/2, bitmap.getWidth()/2, paint);
imageView.setImageBitmap(circleBitmap);
Image inside the circle:
How can I do this?
I too needed a rounded ImageView, I used the below code, you can modify it accordingly:
import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.Bitmap.Config;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.PorterDuff.Mode;
import android.graphics.PorterDuffXfermode;
import android.graphics.Rect;
import android.graphics.drawable.BitmapDrawable;
import android.graphics.drawable.Drawable;
import android.util.AttributeSet;
import android.widget.ImageView;
public class RoundedImageView extends ImageView {
public RoundedImageView(Context context) {
super(context);
}
public RoundedImageView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public RoundedImageView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
#Override
protected void onDraw(Canvas canvas) {
Drawable drawable = getDrawable();
if (drawable == null) {
return;
}
if (getWidth() == 0 || getHeight() == 0) {
return;
}
Bitmap b = ((BitmapDrawable) drawable).getBitmap();
Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);
int w = getWidth();
#SuppressWarnings("unused")
int h = getHeight();
Bitmap roundBitmap = getCroppedBitmap(bitmap, w);
canvas.drawBitmap(roundBitmap, 0, 0, null);
}
public static Bitmap getCroppedBitmap(Bitmap bmp, int radius) {
Bitmap sbmp;
if (bmp.getWidth() != radius || bmp.getHeight() != radius) {
float smallest = Math.min(bmp.getWidth(), bmp.getHeight());
float factor = smallest / radius;
sbmp = Bitmap.createScaledBitmap(bmp,
(int) (bmp.getWidth() / factor),
(int) (bmp.getHeight() / factor), false);
} else {
sbmp = bmp;
}
Bitmap output = Bitmap.createBitmap(radius, radius, Config.ARGB_8888);
Canvas canvas = new Canvas(output);
final String color = "#BAB399";
final Paint paint = new Paint();
final Rect rect = new Rect(0, 0, radius, radius);
paint.setAntiAlias(true);
paint.setFilterBitmap(true);
paint.setDither(true);
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(Color.parseColor(color));
canvas.drawCircle(radius / 2 + 0.7f, radius / 2 + 0.7f,
radius / 2 + 0.1f, paint);
paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
canvas.drawBitmap(sbmp, rect, rect, paint);
return output;
}
}
