原因分析：
Android的每一個(gè)Activity都有個(gè)WindowManager窗體管理器继低，同樣文兑，構(gòu)建在某個(gè)Activity之上的對(duì)話框、PopupWindow也有相應(yīng)的WindowManager窗體管理器竖席。因?yàn)閷?duì)話框旬蟋、PopupWindown不能脫離Activity而單獨(dú)存在著油昂，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異常了倾贰，因?yàn)檫@個(gè)Dialog(或PopupWindow)的WindowManager已經(jīng)沒有誰(shuí)可以附屬了冕碟，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前匆浙，要確保附屬在上面的Dialog或PopupWindow已經(jīng)關(guān)閉(dismiss)了安寺。
