Popuwindow点击外部控件切换popuwindow——解决点击外部事件不响应问题。

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。如图当你需要写一个通用控件，而不希望收到父布局限制的时候，你可能就要用到popuwindow，但是popuwindow有个问题，就是你在点击如图的三个tab的时候，你会发现，永远都是上一个popuwindow先消失，然后你要再点一下，新的popuwindow才会出现。

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。
