ObjectAnimator 动画后恢复初始状态

位移后 恢复状态：mMiddleAvatar.setTranslationX(0);

改变透明度之后恢复：mMiddleAvatar.setAlpha(1.0f);

旋转后恢复：mMiddleAvatar.setRotation(0);

缩放后恢复：

mMiddleAvatar.setScaleX(1.0f);
    mMiddleAvatar.setScaleY(1.0f);

取消 AnimatorSet 动画：

if (mLastAnimatorSet != null) {
        mLastAnimatorSet.cancel();
    }
    这种取消会走 onAnimationEnd 回调

所以自定义一个 AnimatorListenerAdapter

public abstract class CancelAnimatorListenerAdapter extends AnimatorListenerAdapter {
        private boolean mCanceled = false;
    
        @Override
        public void onAnimationCancel(Animator animation) {
            super.onAnimationCancel(animation);
            mCanceled = true;
        }
    
        public boolean isCanceled() {
            return mCanceled;
        }
    }

使用：

ObjectAnimator rightAvatarScaleXAnimator = ObjectAnimator.ofFloat(mRightAvatar, "scaleX", 1.03f, 1.0f);
    ObjectAnimator rightAvatarScaleYAnimator = ObjectAnimator.ofFloat(mRightAvatar, "scaleY", 1.03f, 1.0f);
    mLastAnimatorSet = new AnimatorSet();
    mLastAnimatorSet.play(rightAvatarScaleXAnimator).with(rightAvatarScaleYAnimator);
    mLastAnimatorSet.setDuration(100);
    mLastAnimatorSet.start();
    mLastAnimatorSet.addListener(new CancelAnimatorListenerAdapter() {
        @Override
        public void onAnimationEnd(Animator animation) {
            super.onAnimationEnd(animation);
            if (isCanceled()) {return;}
            if (mMiddleAvatar == null) { return; }
            mRightAvatar.setTranslationX(0);
            mRightAvatar.setAlpha(0.0f);
            mRightAvatar.setScaleX(1.0f);
            mRightAvatar.setScaleY(1.0f);
            mMiddleAvatar.setAlpha(1.0f);
            startMatchTipsAnimation();
        }
    });
