当前回答

我在AlertDialog上错误地调用hide()而不是dismiss()触发了这个错误。

其他回答

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
    }

}

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();
 }

这就是我如何解决这个bottomSheetDialog.dismiss()在活动的finesh()之前的对话框

  startActivity(Intent(this, Activity::class.java))
        bottomSheetDialog.dismiss()
        finish()

解决方案是在退出Activity之前在view .java:183中创建的对话框上调用dismiss(),例如在onPause()中。所有的窗口和对话框应该在离开一个活动之前关闭。

我对此有另一个解决方案,想知道它是否对你有效:而不是在onDestroy中解散,这似乎是主要的解决方案,我正在扩展ProgressDialog…

public class MyProgressDialog extends ProgressDialog {

  private boolean isDismissed;

  public MyProgressDialog(Context context) {
    super(context);
  }

  @Override
  public void onDetachedFromWindow() {
    super.onDetachedFromWindow();
    dismiss();
  }

  @Override
  public void dismiss() {
    if (isDismissed) {
      return;
    }
    try {
      super.dismiss();
    } catch (IllegalArgumentException e) {
      // ignore
    }
    isDismissed = true;
  }

AFAIC更可取,因为您不必将进度对话框作为成员,只需触发(显示)并忘记即可
