Android问题集锦之二十Activityhasleakedwindowthatwasoriginall

今天调试程序时log中突然打印这样的错误&＃xff0c;但是程序并没有crash&＃xff0c;为了不放过一个错误&＃xff0c;我决定调查一下。

当时是离开一个activity&＃xff0c;然后提示是否退出此界面&＃xff0c;接下来就打印此错误&＃xff1a;

显然&＃xff0c;我用Dialog确认是否退出&＃xff0c;但是activity销毁后并没有处理Dialog的退出。

解决办法&＃xff1a;

知道了问题所在就容易解决问题了。只需要在activity销毁时关闭Dialog就好。

 &＃64;Override protected void onDestroy() {  if(mDialog !&＃61; null) {   mDialog.dismiss();  }  super.onDestroy(); }
