Xamarin表单：是否可以在Material中使用CoordinatorLayout和AppBarLayout？

Question

我正在尝试实施以下内容：http://blog.grafixartist.com/quick-return-pattern-with-android-design-support-library/

当我创建一个新的Forms项目时，我得到以下Toolbar.axml

<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="?attr/colorPrimary"
    android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    android:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

MainActivity.cs

using System;

using Android.App;
using Android.Content.PM;
using Android.Runtime;
using Android.Views;
using Android.Widget;
using Android.OS;

namespace ListViewT.Droid
{
    [Activity(Label = "ListViewT", Icon = "@drawable/icon", Theme = "@style/MainTheme", MainLauncher = true, ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation)]
    public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsAppCompatActivity
    {
        protected override void OnCreate(Bundle bundle)
        {
            TabLayoutResource = Resource.Layout.Tabbar;
            ToolbarResource = Resource.Layout.Toolbar;

            base.OnCreate(bundle);

            global::Xamarin.Forms.Forms.Init(this, bundle);
            LoadApplication(new App());
        }
    }
}

查看FormsAppCompatActivity，这些布局似乎没有任何内容：

public class FormsAppCompatActivity : AppCompatActivity, IDeviceInfoProvider, IStartActivityForResult
    {
        protected FormsAppCompatActivity();

        public static int TabLayoutResource { get; set; }
        public static int ToolbarResource { get; set; }

        public static event BackButtonPressedEventHandler BackPressed;
        public event EventHandler ConfigurationChanged;

        public override void OnBackPressed();
        public override void OnConfigurationChanged(Configuration newConfig);
        public override bool OnOptionsItemSelected(IMenuItem item);
        public void SetStatusBarColor(global::Android.Graphics.Color color);
        protected void LoadApplication(Application application);
        protected override void OnActivityResult(int requestCode, Result resultCode, Intent data);
        protected override void OnCreate(Bundle savedInstanceState);
        protected override void OnDestroy();
        protected override void OnNewIntent(Intent intent);
        protected override void OnPause();
        protected override void OnRestart();
        protected override void OnResume();
        protected override void OnStart();
        protected override void OnStop();

        public delegate bool BackButtonPressedEventHandler(object sender, EventArgs e);
    }

是否可以利用CoordinatorLayout和AppBarLayout？
