How to dynamically add MvxFrameControl in MvvmCross Android - mvvmcross

Question

I need to dynamically create MvxFrameControll, inflate it with content and add to another Layout (FrameLayout / LinearLayout).
My code is
HomeScreen.axml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:local="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<krista.fm.iMonitoring.Android.Native.TopBar
android:layout_width="match_parent"
android:layout_height="50dp"
local:MvxBind="DataContext TopBar"
local:MvxTemplate="#layout/topbar"
android:id="#+id/TopBar" />
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/SubjectBodyContainer" />
</LinearLayout>
public class SubjectBody : MvxFrameControl
{
public SubjectBody (Context context, IAttributeSet attrs) : base (context, attrs)
{
}
public SubjectBody (int templateId, Context context, IAttributeSet attrs) : base (context, attrs)
{
}
protected override void OnContentSet ()
{
base.OnContentSet ();
}
}
HomeScreenView
[Activity (Label = "HomeScreen")]
public class HomeScreenView : MvxActivity
{
public override void OnAttachedToWindow()
{
base.OnAttachedToWindow();
}
protected override void OnCreate (Bundle bundle)
{
base.OnCreate (bundle);
SetContentView (Resource.Layout.HomeScreen);
AddSubjectBody();
}
protected override void OnStart()
{
base.OnStart();
}
protected virtual void AddSubjectBody()
{
var container = FindViewById<FrameLayout>(Resource.Id.SubjectBodyContainer);
var subjectBody = new SubjectBody(Resource.Layout.SubjectBody, this, null);
subjectBody.DataContext = new SubjectBodyViewModel();
container.AddView(subjectBody, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MatchParent, ViewGroup.LayoutParams.MatchParent));
}
}
Why this code doesn't add content on screen and how it rewrite rightly? When I use SubjectBody adding inside axml with templateId it works correctly. But what if i need adding this dynamically?
protected virtual void AddSubjectBody()
{
var container = FindViewById<FrameLayout>(Resource.Id.SubjectBodyContainer);
var subjectBody = new SubjectBody(Resource.Layout.SubjectBody, this, null);
subjectBody.DataContext = new SubjectBodyViewModel();
container.AddView(subjectBody, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MatchParent, ViewGroup.LayoutParams.MatchParent));
}

Are you sure your code is running on the UI thread? I'm using pretty a similar code in one app and the view gets added into the parent. What I suggest you to try is:
this.RunOnUiThread(() => container.AddView(this.subjectBody));
