public void addListener(AnimatorListener listener) 

Source Link

Document

Adds a listener to the set of listeners that are sent events through the life of an animation, such as start, repeat, and end.

Usage

From source file:Main.java

public static void startScaleAnime(final View view, float newScale, Animator.AnimatorListener listener) {
    ValueAnimator anime = ValueAnimator.ofFloat(view.getScaleX(), newScale);
    anime.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
        @Override/*from w  w  w  . ja  v a 2s .  c om*/
        public void onAnimationUpdate(ValueAnimator animation) {
            float s = Float.parseFloat(animation.getAnimatedValue().toString());
            view.setScaleX(s);
            view.setScaleY(s);
        }
    });
    if (listener != null) {
        anime.addListener(listener);
    }
    anime.setDuration(mAnimeDuration);
    anime.start();
}
