代码示例来源：origin: bumptech/glide

@Override
public int getSize() {
 // 4 bytes per pixel for ARGB_8888 Bitmaps is something of a reasonable approximation. If
 // there are no intrinsic bounds, we can fall back just to 1.
 return Math.max(1, drawable.getIntrinsicWidth() * drawable.getIntrinsicHeight() * 4);
}

public static Bitmap drawableToBitmap (Drawable drawable) {

    BitmapDrawable bitmapDrawable = (BitmapDrawable) drawable;
    if(bitmapDrawable.getBitmap() != null) {
      return bitmapDrawable.getBitmap();
    }
  }

  if(drawable.getIntrinsicWidth() <= 0 || drawable.getIntrinsicHeight() <= 0) {
    bitmap = Bitmap.createBitmap(1, 1, Bitmap.Config.ARGB_8888); // Single color bitmap will be created of 1x1 pixel
  } else {
    bitmap = Bitmap.createBitmap(drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight(), Bitmap.Config.ARGB_8888);
  }

  Canvas canvas = new Canvas(bitmap);
  drawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());
  drawable.draw(canvas);
  return bitmap;
}
