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

这里有一个解决方案，当你想要解散AlertDialog，但不想在活动中保留对它的引用。

解决方案要求您拥有androidx。项目中的生命周期依赖关系(我相信在评论的时候，这是一个常见的需求)

这让你可以将对话框的解散委托给外部对象(观察者)，你不需要再关心它了，因为当活动终止时它会自动取消订阅。(这里是证明:https://github.com/googlecodelabs/android-lifecycles/issues/5)。

因此，观察者保持对对话的引用，而活动保持对观察者的引用。当“onPause”发生时-观察者解散对话框，当“onDestroy”发生时-活动删除观察者，所以没有泄漏发生(好吧，至少我不会在logcat中看到错误)

// observer
class DialogDismissLifecycleObserver( private var dialog: AlertDialog? ) : LifecycleObserver {
    @OnLifecycleEvent(Lifecycle.Event.ON_PAUSE)
    fun onPause() {
        dialog?.dismiss()
        dialog = null
    }
}
// activity code
private fun showDialog() {
        if( isDestroyed || isFinishing ) return
        val dialog = AlertDialog
            .Builder(this, R.style.DialogTheme)
            // dialog setup skipped
            .create()
        lifecycle.addObserver( DialogDismissLifecycleObserver( dialog ) )
        dialog.show()
}

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

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() {
       ...        
      }
    });

确保打电话 this.dialog.show。(活动)

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。
