1：在acti里调用代码
Animation shakeAnim = AnimationUtils.loadAnimation(mContext, R.anim.shake_y);
passWd.startAnimation(shakeAnim);
2：在anim目录下的shake_y.xml
<?xml version="1.0" encoding="utf-8"?> <translate xmlns:andro >
</translate>
3在anim下的cycle.xml文件:
cycles值用来控制摆动的幅度
<?xml version="1.0" encoding="utf-8"?>
<cycleInterpolator xmlns:andro />
