Android - ImageView crop (mask) image as par background shape

Here is sample code to crop image as par background shape. You'll need two drawable, one for background and one for masking.

	
ImageView mImageView = (ImageView) findViewById(R.id.myImageView);
Bitmap original = BitmapFactory.decodeResource(getResources(),
R.drawable.random_drawable);
Bitmap mask = BitmapFactory.decodeResource(getResources(),
R.drawable.mask_drawable);
original = Bitmap.createScaledBitmap(original, mask.getWidth(),
mask.getHeight(), true);
	
Bitmap result = Bitmap.createBitmap(mask.getWidth(), mask.getHeight(),
Config.ARGB_8888);
Canvas mCanvas = new Canvas(result);
Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG);
paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.DST_IN));
mCanvas.drawBitmap(original, 0, 0, null);
mCanvas.drawBitmap(mask, 0, 0, paint);
paint.setXfermode(null);
mImageView.setImageBitmap(result);
mImageView.setScaleType(ScaleType.FIT_XY);
mImageView.setBackgroundResource(R.drawable.background_drawable);
