问题描述：
popuwindow的原理这里就不赘述了。使用过的人都会发现一个问题。如图
很多人想过通过释放touch事件把点击事件交给父布局处理。但是问题是，popuwindow在new的时候你就会发现，貌似不是从父布局来的，那么事件就无法交给父布局。
找了一些资料，都没有现成的接口或者事件处理能够很好的解决这个问题，很多人说可以换成dialog，我去，这真但想多了，用dialog问题会跟多。
所以还是自己想办法解决。
解决方案：
pupuwindow展示的时候，监听touchevent的坐标。然后判断该坐标是否在tab可点击范围以内，然后强行出发tab点击。
原理我就不再赘述了，代码贴的很明白，也没有特别复杂的逻辑。关键看下checkPointInCtrlBtn这个函数。
