Usage

From source file:com.android.clear.reminder.ItemAnimator.java

@Override
public boolean animateAdd(final ViewHolder holder) {
    endAnimation(holder);//from w ww  .ja va 2  s. c  o  m

    final float prevAlpha = holder.itemView.getAlpha();
    holder.itemView.setAlpha(0f);

    final Animator addAnimator = ObjectAnimator.ofFloat(holder.itemView, View.ALPHA, 1f)
            .setDuration(getAddDuration());
    addAnimator.addListener(new AnimatorListenerAdapter() {
        @Override
        public void onAnimationStart(Animator animator) {
