重要的事情说三遍
fillBefore是指动画结束时画面停留在第一帧，fillAfter是指动画结束是画面停留在最后一帧。最关键的问题是，这2个参数不能在</alpha>,</scale>,</translate>,</rotate>中设置，这是没有用的，必须在动画xml文件的</set>节点中设置。如果是代码必须在AnimationSet中设置。

/**
* Tween Animations的通用方法
1、setDuration(long durationMills)
设置动画持续时间（单位：毫秒）
2、setFillAfter(Boolean fillAfter)
如果fillAfter的值为true,则动画执行后，控件将停留在执行结束的状态
3、setFillBefore(Boolean fillBefore)
如果fillBefore的值为true，则动画执行后，控件将回到动画执行之前的状态
4、setStartOffSet(long startOffSet)
设置动画执行之前的等待时间
5、setRepeatCount(int repeatCount)
设置动画重复执行的次数
