I'm not sure offhand why this crashes, but it could be any number of
reasons... If you could post the logcat output, that would be very helpful.
Also, I was wondering what you were trying to accomplish with this? If you
are trying to change the image when a touch event occurs and then have it
change back when the touch event is done, you may want to consider using a
selector drawable instead...
It allows you to specify a single drawable that will change based on the
state of the object... i.e. onFocus, onPressed, etc....
I just barely figured out how to do that and there wasn't a whole lot of
documentation available. If that is what you are trying to do I will post
again with how to do that...
Thanks,
Justin
