活动泄漏了最初添加的窗口

这个错误是什么，为什么会发生?

当前回答

有问题，当一个ProgressDialog仍然显示时，我完成了一个活动。

所以首先隐藏对话框，然后完成活动。

其他回答

你可以通过一个简单的/愚蠢的错误得到这个异常，通过(例如)在显示AlertDialog后不小心调用finish()，如果你错过了switch语句中的break call语句……

   @Override
   public void onClick(View v) {
    switch (v.getId()) {
        case R.id.new_button:
            openMyAlertDialog();
            break; <-- If you forget this the finish() method below 
                       will be called while the dialog is showing!
        case R.id.exit_button:
            finish();
            break;
        }
    }

finish()方法将关闭Activity，但AlertDialog仍然显示!

因此，当您专注地盯着代码，寻找糟糕的线程问题或复杂的编码等时，不要只见树不见林。有时它可能只是一些简单而愚蠢的事情，如缺少break语句。：）

我在我的视频播放器应用程序中获取了这些日志。这些消息是在视频播放器关闭时抛出的。有趣的是，我曾经以随机的方式在几次运行中获得这些日志。此外，我的应用程序不涉及任何progressdialog。最后，我用下面的实现解决了这个问题。

@Override
protected void onPause()
{
    Log.v("MediaVideo", "onPause");
    super.onPause();
    this.mVideoView.pause();
    this.mVideoView.setVisibility(View.GONE);
}

@Override
protected void onDestroy()
{
    Log.v("MediaVideo", "onDestroy");
    super.onDestroy();
}

@Override
protected void onResume()
{
    Log.v("MediaVideo", "onResume");
    super.onResume();
    this.mVideoView.resume();
}

覆盖OnPause调用mVideoView.pause()和设置可见性为GONE。通过这种方式，我可以解决“活动已泄漏窗口”日志错误问题。

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

如果你在doInBackground()函数中有一个错误，并且有这样的代码，就会出现这种情况。

最后尝试添加对话。首先检查并修复doInBackground()函数

protected void onPreExecute() {
     super.onPreExecute();
     pDialog = new ProgressDialog(CreateAccount.this);
     pDialog.setMessage("Creating Product..");
     pDialog.setIndeterminate(false);
     pDialog.setCancelable(true);
     pDialog.show();

 }

 protected String doInBackground(String...args) {
     ERROR CAN BE IS HERE
 }

 protected void onPostExecute(String file_url) {
     // dismiss the dialog once done
     pDialog.dismiss();

  if (mActivity != null && !mActivity.isFinishing() && mProgressDialog != null && mProgressDialog.isShowing()) {
        mProgressDialog.dismiss();
    }
