Without looking at your source code, it looks like you've passed an invalid color into your background property upon clicking the button. It looks like you have a class named ColorWheel. I would revisit that class and make sure you've formatted your colors properly, either as HEX values (#FFFFFF) or as android system colors (Color.BLACK).
