当前回答

试试下面的代码:

public class Sample extends Activity(){
@Override
 public void onCreate(Bundle instance){

}
 @Override
    public void onStop() {
        super.onStop();
      progressdialog.dismiss(); // try this
    }

}

其他回答

我也曾面临过这个问题,但我意识到这并不是因为我的对话框,而是因为ActionMode。所以如果你试图在ActionMode打开时完成活动,就会导致这个问题。在你的活动的onPause完成动作模式。

 private ActionMode actionMode;

 @Override
 public void onActionModeStarted(ActionMode mode) {
    super.onActionModeStarted(mode);
    actionMode = mode;
 }

 @Override
 protected void onPause() {
    super.onPause();
    if (actionMode != null) actionMode.finish();
 }

不仅尝试显示警报,而且当您完成一个特定的活动实例并尝试启动新的活动/服务或尝试停止它时,还可以调用它。

例子:

OldActivity instance;

    oncreate() {
       instance=this;
    }
    instance.finish();
    instance.startActivity(new Intent(ACTION_MAIN).setClass(instance, NewActivity.class));

只需确保您的活动不会由于代码中某处引发的异常而意外关闭。通常在异步任务中,当activity在doinBackground方法中面临强制关闭时,asynctask返回到onPostexecute方法。

我也有同样的问题。错误不在对话框中,而是在编辑文本中。我试图改变一个异步任务内的编辑文本的值。我唯一能解决的问题就是创造一个新的可运行对象。

runOnUiThread(new Runnable(){
      @Override
      public void run() {
       ...        
      }
    });  

这个问题的答案都是正确的,但让我有点困惑,不知道为什么。在玩了大约2个小时后,我发现了这个错误的原因:

你已经知道,从阅读其他答案,有X已泄漏窗口DecorView@d9e6131[]错误意味着一个对话框打开时,你的应用程序关闭。但是为什么呢?

它可能是,当你的对话框打开时,你的应用程序因为其他原因崩溃了

这导致你的应用程序关闭,因为你的代码中的一些错误,这导致对话框保持打开的同时,你的应用程序关闭,由于其他错误。

所以,仔细检查你的逻辑。解决第一个错误,然后第二个错误会自己解决

一个错误导致另一个错误,又导致另一个错误,就像DOMINOS!
