Question

I am trying to get my animation to spin until the user clicks on the view. I have set the animation to spin once and I want it to keep going on some kind of loop instead of using .clearAnimation so that the animation doesnt just stop half way through a cycle when clicked. The code I have come up with so obviously won’t work but I can think of how to do it!

while(keepSpinning){

    turntable = (ImageView)findViewById(R.id.deck1);     

    RotateAnimation r ; // = new RotateAnimation(ROTATE_FROM, ROTATE_TO);
    r = new RotateAnimation(ROTATE_FROM, ROTATE_TO, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
    r.setDuration(5000);
    r.setRepeatCount(0); 

    turntable.startAnimation(r);
    turntable.setOnTouchListener(new View.OnTouchListener() {

        @Override
        public boolean onTouch(View arg0, MotionEvent arg1) {
            keepSpinning = false;
            return true;
        }
    });
}

Instead of the while(keepSpinning) loop, register an AnimationListener with the RotateAnimation. The RotateAnimation will invoke onAnimationRepeat() on your listener for each loop of the animation, and you can cancel the animation there.
