MarkerClick有效，但InfoWindowClick无法打开ViewModel

Question

以下MarkerClick实现工作，非常好。我可以通过ShowViewModel打开其他视图

View.cs

mMap.MarkerClick += MMap_MarkerClick;

private void MMap_MarkerClick(object sender, GoogleMap.MarkerClickEventArgs e)
{
   ViewModel.MapInfoSelected(e.Marker.Title);
}

ViewModel.cs

public void MapInfoSelected(string name)
{
    ShowViewModel<StudentViewModel>(new { studentName = name});
}

---

InfoWindowClick不会触发打开其他View。

View.cs

mMap.InfoWindowClick += MMap_InfoWindowClick;

private void MMap_InfoWindowClick(object sender, GoogleMap.InfoWindowClickEventArgs e)
{
  ViewModel.MapInfoSelected(e.Marker.Title);
}

ViewModel.cs

public void MapInfoSelected(string name)
{
 // it hits here, but does not hit `StudentViewModel` Init() method, the app is frozen and do nothing
    ShowViewModel<StudentViewModel>(new { studentName = name});
}

我甚至尝试了SetOnInfoWindowClickListener如下，它也没有打开视图。

 mMap.SetOnInfoWindowClickListener(this);

 public void OnInfoWindowClick(Marker marker)
 {
     ViewModel.MapInfoSelected(marker.Title);
 }

更新：

它甚至击中了OnPause()方法，但如果我使用StudentViewModel事件，它仍然不会调用InfoWindowClick Init（）方法

 public override void OnPause()
 {
   base.OnPause();
   mMap.InfoWindowClick -= MMap_InfoWindowClick;
 }

在onCreate，把mViewModel.getLiveData().observe(this, new Observer<List<YOUR STUFF>>(){和.observe放在init()方法，这对我有用
