我以编程方式生成UI并在OnCreateView中进行绑定，并且在视图呈现在屏幕上之前会有明显的延迟。
我想知道是否可以延迟绑定，以便首先呈现控件并遵循绑定。请告知合适的功能。
原始代码：
public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
try
{
var fragmentView = base.OnCreateView(inflater, container, savedInstanceState);
var linearLayout = fragmentView.FindViewById<LinearLayout>(Resource.Id.linearLayout1);
BindingContext = new MvxAndroidBindingContext(Activity, new MvxSimpleLayoutInflater(inflater), ViewModel);
using (new MvxBindingContextStackRegistration<IMvxAndroidBindingContext>(
((IMvxAndroidBindingContext)BindingContext)))
{
var set = this.CreateBindingSet<ArticleFragment, ArticleFragmentViewModel>();
// Name field (one of many fields...
set.Bind(InflateEditableText(inflater, linearLayout, "Name"))
.For(v => v.Text)
.To(vm => vm.Item.Name)
.WithConversion("TrimmableString");
InflateAndBindValidationText(inflater, linearLayout, set, "Validator.Messages['Name']");
//
// Other fields follow... same pricinple as Name field
//
set.Apply();
}
return fragmentView;
}
catch (Exception ex)
{
System.Diagnostics.Debug.WriteLine(ex.Message);
throw;
}
}
我还重构了代码以完成任务中的所有绑定，但是我得到了与某些“集合已更改”相关的间歇性错误（无法记住确切的错误）。我们的想法是通过ui线程完成布局，并在单独的线程上完成绑定，并在set.Apply（）之前完成task.Wait（）。它有效，但间歇性失败。
编辑：添加了跟踪。
