You can make a Paint and setXfermode to XOR (PixelXorXfermode) and the draw a solid rect on the bitmap. It will invert every bit - so when you do it once more you are back to non-inverted. I am doing so in my keyboard (http://www.maxikeys.com) to invert pressed keys - the room between the keys have the color 50% grey, which will not change, when being inverted.
