How to convert LayerDrawable to Bitmap?

Question

I'm using the Universal Image Loader for Android (here is the link)

I need to to load an Image from a URL and overlay it to another image. The library can not do it by default, so I'm try to change it. The problem is that now I need to convert a LayerDrawable to Bitmap. How can I do that?

Answer 1

Just draw it on a Canvas which is backed by a Bitmap.

int width = drawable.getIntrinsicWidth();
int height = drawable.getIntrinsicHeight();
Bitmap bitmap = Bitmap.createBitmap(width, height, Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap); 
drawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());
drawable.draw(canvas);
