当前回答

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。

其他回答

我最近也遇到了同样的问题。

这个问题背后的原因是在对话框被解散之前活动被关闭了。上述情况的发生有多种原因。上面的帖子中提到的也是正确的。

我陷入了一种情况，因为在线程中，我调用了一个抛出异常的函数。因此，窗口被关闭，因此出现异常。

确保打电话 this.dialog.show。(活动)

也许你在activity中使用了findViewById而不是dialog。findViewById，然后在空实例上设置OnClickListener，这可能会导致原始错误。

比之前的答案晚得多，在2022年人们使用Kotlin时，当Kotlin协程试图从错误的(非main)协程上下文修改弹出窗口时，我们也得到了错误。

产生错误:

CoroutineScope(Dispatchers.IO).launch{
    someCodeThatNeedsOtherContext()
    someViewBinding.someAttribute = someValue // We get the error here
}

不产生错误:

CoroutineScope(Dispatchers.IO).launch{
    someCodeThatNeedsOtherContext()
    CoroutineScope(Dispatchers.Main).launch{
        someViewBinding.someAttribute = someValue // No error here
    }
}

唯一的答案是

  @Override
    public void onBackPressed() {

        exit_popup();
       // super.onBackPressed(); remove this line

    }
