直接从项目里面拷贝出来的，出错代码为show一个ProgressDialog。还有一种情况就是ProgressDialog还在显示的时候，finish activity也会出现。

原因分析：
Android的每一个Activity都有个WindowManager窗体管理器，同样，构建在某个Activity之上的对话框、PopupWindow也有相应的WindowManager窗体管理器。因为对话框、PopupWindown不能脱离Activity而单独存在着，所以当某个Dialog或者某个PopupWindow正在显示的时候我们去finish()了承载该Dialog(或PopupWindow)的Activity时，就会抛Window Leaked异常了，因为这个Dialog(或PopupWindow)的WindowManager已经没有谁可以附属了，所以它的窗体管理器已经泄漏了。

解决办法：
关闭(finish)某个Activity前，要确保附属在上面的Dialog或PopupWindow已经关闭(dismiss)了。
