The android.view.animation.Animation class (returned by AnimationUtils.loadAnimation has a nested interface called AnimationListener which you can use to determine when an animation has completed. Specifically, you'd be interested in implementing the onAnimationEnd method of the listener interface.

Obviously, you'd also have to call setAnimationListener on the Animation instance returned by loadAnimation.
