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

你必须在AsyncTask的onPreExecute方法中创建Progressdialog对象，你应该在onPostExecute方法中解散它。

在我的例子中，原因是我忘记在Android manifest文件中包含权限。

我是怎么知道的?好吧，就像@Bobby在接受的答案下面的评论中所说的那样，只要进一步向上滚动到日志，就会看到真正抛出异常的第一个原因或事件。显然，消息“活动已经泄漏了最初添加的窗口”只是一个异常，无论第一个异常是什么。

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();
 }

根据我的问题是，你正在尝试调用一个对话框后，一个活动正在完成，所以根据我，你可以做的是给一些延迟使用处理程序，你的问题将得到解决，例如:

 Handler handler=new Handler();
     handler.postDelayed(new Runnable() {
                @Override
                public void run() {
                     dialog.show();
                     //or
                     dialog.dismiss();

                }
            },100);

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
