 * valueAnimator,objectAnimator,AnimatorSet 一般都用objectanimation
 * translationX Y 平移
 * rotation 旋转
 * scale 翻转
 * scaleX + scaleY 缩放
 * alpha
 * <p/>
 * <p/>
 * 实现组合动画功能主要需要借助AnimatorSet这个类，这个类提供了一个play()方法，
 * 如果我们向这个方法中传入一个Animator对象(ValueAnimator或ObjectAnimator)将会返回一个AnimatorSet.Builder的实例，AnimatorSet.Builder中包括以下四个方法：
 * after(Animator anim)   将现有动画插入到传入的动画之后执行
 * after(long delay)   将现有动画延迟指定毫秒后执行
 * before(Animator anim)   将现有动画插入到传入的动画之前执行
 * with(Animator anim)   将现有动画和传入的动画同时执行

     * 基本用法
     * <p/>
     * /如果是多个动画按上面这样播放会给每个objectAnimator分别每个动画都有加不是整体
     * animSet.setInterpolator();设置补间器默认是AccelerateDecelerateInterpolator。先加速再减速
     * new AccelerateInterpolator(2f)2f加速倍数/
     * new BounceInterpolator()模拟物理规律有回弹
     * DecelerateInterpolator(2f)2f减速倍数
     * OvershootInterpolator(1f)表示向前甩一定值后再回到原来位置
     * AnticipateOvershootInterpolator(1f)：表示开始的时候向后然后向前甩一定值后返回最后的值
     * CycleInterpolator：表示动画循环播放特定的次数，速率改变沿着正弦曲线。
     * LinearInterpolator：表示以常量速率改变。
