I wanted image to have rounded corners. I implement this xml code and use this in my image view. but image overlap the shape. I am downloading the image through async task.<
You should use RoundedCornersTransformation
from this library and create a circular ImageView
.

DIAGONAL_FROM_TOP_LEFT, DIAGONAL_FROM_TOP_RIGHT
}
private int mRadius;
private int mDiameter;
private int mMargin;
private CornerType mCornerType;
public RoundedCornersTransformation(int radius, int margin) {
this(radius, margin, CornerType.ALL);
}

mRadius = radius;
mDiameter = radius * 2;
mMargin = margin;
mCornerType = cornerType;
}

return bitmap;

May be you have found your solution but recently i found new library which allows you to create any many shape you want to set to the Image VIew.
<com.makeramen.roundedimageview.RoundedImageView......... app:riv_corner_radius="Yourradiusdip"/>
Based on Nihal's answer ( https://stackoverflow.com/a/42234152/2832027 ), here is a pure XML version that gives a rectangle with rounded corners on API 24 and above. On below API 24, it will show no rounded corners.
Usage:
<ImageView
android:id="@+id/thumbnail"
android:layout_width="150dp"
android:layout_height="200dp"
android:foreground="@drawable/rounded_corner_mask"/>
rounded_corner_mask.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:gravity="bottom|right">
<vector xmlns:android="http://schemas.android.com/apk/res/android"
android:width="@dimen/rounding_radius"
android:height="@dimen/rounding_radius"
android:viewportWidth="10.0"
android:viewportHeight="10.0">

here is something I found from here: github
made a little improvising. Very simple and clean. No external files or methods:
public class RoundedImageView extends ImageView {
private float mCornerRadius = 10.0f;
public RoundedImageView(Context context) {
super(context);
}
public RoundedImageView(Context context, AttributeSet attributes) {
super(context, attributes);
}
@Override
protected void onDraw(Canvas canvas) {
// Round some corners betch!
Drawable myDrawable = getDrawable();
if (myDrawable!=null && myDrawable instanceof BitmapDrawable && mCornerRadius > 0) {
Paint paint = ((BitmapDrawable) myDrawable).getPaint();
final int color = 0xff000000;
Rect bitmapBounds = myDrawable.getBounds();
final RectF rectF = new RectF(bitmapBounds);
// Create an off-screen bitmap to the PorterDuff alpha blending to work right
int saveCount = canvas.saveLayer(rectF, null,
Canvas.MATRIX_SAVE_FLAG |
Canvas.CLIP_SAVE_FLAG |
Canvas.HAS_ALPHA_LAYER_SAVE_FLAG |
Canvas.FULL_COLOR_LAYER_SAVE_FLAG |
Canvas.CLIP_TO_LAYER_SAVE_FLAG);
// Resize the rounded rect we'll clip by this view's current bounds
// (super.onDraw() will do something similar with the drawable to draw)
getImageMatrix().mapRect(rectF);
paint.setAntiAlias(true);
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(color);
canvas.drawRoundRect(rectF, mCornerRadius, mCornerRadius, paint);
Xfermode oldMode = paint.getXfermode();
// This is the paint already associated with the BitmapDrawable that super draws
paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
super.onDraw(canvas);
paint.setXfermode(oldMode);
canvas.restoreToCount(saveCount);
} else {
super.onDraw(canvas);
}
}
}
Just wondering if anyone still needs it to be done.
For them: you can use RoundedBitmapDrawable
for your purpose.
Sample Code:
ImageView profilePic = (ImageView) findViewById(R.idimageView);
RoundedBitmapDrawable roundedBitmapDrawable = RoundedBitmapDrawableFactory.create(this.getResources(),bitmap);
roundedBitmapDrawable.setCircular(true);
profilePic.setImageDrawable(roundedBitmapDrawable);
where bitmap
is the image you want to load in imageView.
found the easy way.. round imageview with user define radius:
http://shortcutsandroid.blogspot.in/2015/02/round-image-view-in-android.html
just add imageView.setRadius();
//it will set radius for the round imageView.
