Question

我试图在Android上的Google Maps InfoWindow中使用MvvmCross绑定。我有一个内置MapFragment的MvxFragment。我为InfoWindow创建了一个自定义xml布局，并尝试使用MvxFrameControl来显示它，如下所示：

public class InfoWindow : Java.Lang.Object, GoogleMap.IInfoWindowAdapter
{
    private readonly BaseStateFragment _window;
    private readonly Dictionary<string, Restaurant> _restaurants;

    public InfoWindow(BaseStateFragment window, Dictionary<string, Restaurant> restaurants)
    {
        _window = window;
        _restaurants = restaurants;
    }
    public View GetInfoContents(Marker p0)
    {
        var layoutContainer = new MvxFrameControl(Resource.Layout.fragment_home_map_info, _window.Context, null)
        {
            LayoutParameters = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.WrapContent, ViewGroup.LayoutParams.WrapContent),
            DataContext = _restaurants[p0.Id] //ViewModel
        };

        return layoutContainer;
    }

    public View GetInfoWindow(Marker p0)
    {
        return null;
    }

当我点击标记时，会调用方法GetInfoContents，但没有任何事情发生（事件绑定没问题，我让它无法绑定）。

有什么想法吗？

As Requested，布局文件：

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">
    <include
        android:id="@+id/restaurant_item"
        android:layout_width="310dp"
        android:layout_height="190dp"
        layout="@layout/item_list_restaurant" />
    <Button
        android:id="@+id/bt_open_restaurant"
        android:layout_width="310dp"
        android:layout_height="wrap_content"
        android:text="@string/label_go_restaurant_page"
        android:textColor="@color/colorFacebook"
        android:background="@color/lightBlue"
        android:paddingStart="8dp"
        android:paddingEnd="8dp"
        android:layout_gravity="bottom"
        android:layout_marginTop="8dp"
        android:textAllCaps="true"
        android:layout_marginBottom="4dp" />
</FrameLayout>
