PathMenu 中 将ViewGroup 的子类setVisibility无效。

不知道什么原因，在处理那个pathview的时候，将viewsetVisibility(View.GONE)一直无效，具体原因还未找出，但找到了一个解决方案，先记录一下。

下面是我的布局文件。

PathAnimation中的传入的ViewGroup 是hide_fly_relative。我试过其他的，PathMenu，其实他也没处理好这个问题。有时间得去看看源码。找找原因。

额，前几天找到原因了，其实是因为设置了Animation的setFillAfter（true)。所以在动画结束的时候，那个被施加动画的View 还在继续被动画占用。如果想要取消占用，自然考虑取消动画咯。view.clearAnimation()。结构，就ok了咯
