ObjectAnimator.ofFloat不生效

使用Android系统的属性动画时，发现ObjectAnimator.ofFloat设置后没有响应，换成nineoldandroid，一切正常。

在stackoverflow上搜索一下，发现是手机的开发者选项里面的动画时长缩放被关闭了，修改为1倍缩放即可

On the Galaxy S4, under Developer Options, there is the option Animator duration scale. For some wild reason, this is off by default. After switching this to 1x, my animations on the S4 started to work perfectly. This may be what is causing your problem.
