ObjectAnimator

使用方式：

如果是自定义控件，需要添加setter / getter 方法

使用ObjectAnimator.ofxxx() 创建ObjectAnimator对象

start() 方法执行动画

通用的插值器：

LinearInterpolator:线性插值器：匀速

AccelerateDecelerateInterpolator:先加速后减速

AccelerateInterpolator:持续加速

DecelerateInterpolator:持续减速

AnticipateInterpolator:先回拉一下在进行正常的动画轨迹

OvershootInterpolator:有回弹效果的运动轨迹

AnticipateOvershootInterpolator:开始前回拉，超过回弹

BounceInterpolator:弹跳效果的运动轨迹

CycleInterpolator:余弦曲线

PathInterpolator:自定义动画完成度

FastOutLinearInInterpolator:加速运动

        // FastOutSlowInInterpolator:先加速再减速

        // LinearOutSlowInInterpolator:持续减速
