BindingContext Unknown解决错误MVVMCross

Question

我有一个观点

public class TestView : MvxActionBarActivity
{
    protected override void OnCreate(Bundle bundle)
        {
            base.OnCreate(bundle);

            // Create your application here
            SetContentView(Resource.Layout.TestView);

            var responsesList = this.FindViewById<MvxListView>(Resource.Id.listView);
            var responsesAdapter = new TestViewAdapter(this, (IMvxAndroidBindingContext) BindingContext );
            responsesList.Adapter = responsesAdapter;



            var set = this.CreateBindingSet<TestView, TestViewModel>();
            set.Bind(responsesAdapter).For(s => s.Responses).To(vm => vm.Responses);
            set.Bind(responsesList).For(x => x.ItemsSource).To(vm => vm.Responses);
            set.Bind(responsesList).For(x => x.ItemClick).To(vm => vm.ShowDetailEntry);


            set.Apply();
        }
}

由于某种原因，上面的代码说明绑定上下文的未知解决错误。我无法弄清楚为什么Xamaring MVVM Cross上有大量缺乏教程。我错过了什么：

var responsesAdapter = new TestViewAdapter(this, (IMvxAndroidBindingContext) BindingContext );

'curried' function 适配器代码：

public class TestViewAdapter : MvxAdapter
{
        public TestAdapter(Context context, IMvxAndroidBindingContext bindingContext)
            : base(context, bindingContext)
          {
          }

          public List<TestResponse> Responses { get; set; }

          protected override View GetBindableView(View convertView, object source, int templateId)
             {
                if (Session.CurrentArea == 2)
                {
                    templateId = Resource.Layout.quickview_row;
                }
                return base.GetBindableView(convertView, source, templateId);
             }
}
