Tranfer project from Xamarin.Android to Xamarin.Froms

Hello.

I have the project on Xamarin.Android.
In MainActivity.cs:

protected override void OnCreate(Bundle bundle)
        {
            base.OnCreate(bundle);
            SetContentView(Resource.Layout.Main);

            LinearLayout mainLayout = FindViewById<LinearLayout>(Resource.Id.MyLinearLayout);
        Android.Widget.RelativeLayout rl = new Android.Widget.RelativeLayout(this);
                        ...
            mainLayout.AddView (rl);
                }

Can I add on MainPage only Android.Widget.RelativeLayout in Xamarin.Forms?
