原因分析：
Android的每一個(gè)Activity都有個(gè)WindowManager窗體管理器，同樣，構(gòu)建在某個(gè)Activity之上的對(duì)話框、PopupWindow也有相應(yīng)的WindowManager窗體管理器。因?yàn)閷?duì)話框、PopupWindown不能脫離Activity而單獨(dú)存在著，所以當(dāng)某個(gè)Dialog或者某個(gè)PopupWindow正在顯示的時(shí)候我們?nèi)inish()了承載該Dialog(或PopupWindow)的Activity時(shí)，就會(huì)拋Window Leaked異常了，因?yàn)檫@個(gè)Dialog(或PopupWindow)的WindowManager已經(jīng)沒(méi)有誰(shuí)可以附屬了，所以它的窗體管理器已經(jīng)泄漏了。

解決辦法：
關(guān)閉(finish)某個(gè)Activity前，要確保附屬在上面的Dialog或PopupWindow已經(jīng)關(guān)閉(dismiss)了。
