android.view.WindowLeaked的解决方案

无意中发现windowleaked，错误详细信息如下：

11-28 16:39:10.867: E/WindowManager(14064): android.view.WindowLeaked: Activity com.sbdz.agriculture.activity.ProductActivity has leaked window android.widget.TextView{45ebeb60 I.ED.... ......I. 0,0-210,348} that was originally added here

翻阅资料，发现产生原因：

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Dialog、PopupWindow也有相应的WindowManager窗体管理器。Dialog、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，会抛Window Leaked异常了。

具体解决办法：退出Dialog、PopupWindow之前，先调用dismiss();
