I have a bitmap, which is drawn in my Sprite class, this bitmap is more than one picture in one, so I can animate it.
When I inflate the GameLayout next to my XML, this sprite is drawn. Every time the run() method of my GameActivity is called (with special circumstances) this picture updates itself 4 times, so the animation is through.
This is all running perfectly, but my Problem is, that if I press the button (no matter if the curcumstances are fulfilled), the bitmap jumps to the next picture, so, the bitmap updates itself, without me calling it with view.invalidate().
Do you have any idea how I could stop this?
