How to use RoundedBitmapDrawable

You need to set the corner radius.

Resources res = getResources();
Bitmap src = BitmapFactory.decodeResource(res, iconResource);
RoundedBitmapDrawable dr =
    RoundedBitmapDrawableFactory.create(res, src);
dr.setCornerRadius(Math.max(src.getWidth(), src.getHeight()) / 2.0f);
imageView.setImageDrawable(dr);
