I have avery simple program which uses MediaPLayer. I am new to java and xml and for the life of me can’t figue out why the resume button I created won’t respond to a click event. It does sit on top of a larger imageButton, which should not repsond in this state, but I think the top level button should regardless, no?

I managed to solve my own problem using the following approach:
I replaced all the xml animation with java TranslateAnimation.
I created two separate xml layouts, one for the position of the buttons prior to animation, the other for after. In both layouts, I reference the same buttons, ids, etc…
I created a setAnimationListener each time I begin an animation and then in the onAnimationEnd method, I apply the other xml layout. “setContentView(R.layout.layout2);” Also, immediately after setting the contentView, I had to re-instantiate the buttons, in order to get the click to work.
Now, once the button stops moving, it’s actual location is updated to the final location of it’s appearance, vis-a-vis the animation.
