Xamarin Android popupwindow-充气时崩溃

我正在尝试创建一个弹出窗口，显示一个时钟，实际上我想要的是一个倒计时计时器，但一次只能显示一个！，问题是，当我调用该方法显示包含时钟的弹出窗口时，应用程序崩溃

正在从活动而不是片段调用该方法

代码如下：

public void clockPopup()
{

    LayoutInflater inflater =(LayoutInflater)this.GetSystemService(Context.LayoutInflaterService);

    View myPopup = inflater.Inflate (Resource.Layout.PopUpClockTimer, null);

    RunOnUiThread (() => {
        PopupWindow popup = new PopupWindow (myPopup);
    });

        }

堆栈跟踪如下所示：

下面是我试图膨胀的XML：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/customborder"
    android:orientation="vertical">
    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="1dp"
        android:orientation="vertical">
        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_margin="20dp"
            android:orientation="vertical">

        </LinearLayout>
    </LinearLayout>
</LinearLayout>

有人能看出我哪里出了问题吗

我似乎只需要像这样调用该方法：

RunOnUiThread (() => {
    clockPopup();
});

---

它现在没有崩溃。但不幸的是，它也没有显示弹出窗口。但这是另一篇文章。

你错过了：

popup.ShowAtLocation(...);

或

---

以实际显示弹出窗口。

您可以发布您试图膨胀的XML文件吗？那将有助于分配！嗨，克里斯，XML补充道，但碰巧我已经解决了这个问题。我需要通过runOnUiThread调用该方法。现在没有撞车。但是，现在发生了什么。。。。什么都不是。弹出窗口就是不显示。如果我只是使用SetContentView Resource.Layout.PopUpClockTimer；它显示得很好，但显然我不会以弹出窗口的形式打开它。这方面的任何帮助都会很好。否则我将打开一个新线程。非常感谢。

popup.ShowAsDropDown(...);
