的Android Xamarin NavigationView處理事件錯誤

我工作NavigationView把簡單的菜單，從下面的教程： http://maximeesprit.com/en/xamarin-android-actionbar-en/的Android Xamarin NavigationView處理事件錯誤

但我有下列菜單項不發送事件

我的菜單如下問題像這樣：

而且我的main.xml代碼：

<?xml version="1.0" encoding="utf-8"?> 
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:fitsSystemWindows="true" 
    android:id="@+id/maintActivity_drawerlayout"> 
    <android.support.design.widget.NavigationView 
     android:layout_width="wrap_content" 
     android:layout_height="match_parent" 
     android:layout_gravity="start" 
     android:id="@+id/maintActivity_navigationView" 
     app:menu="@menu/left_menus" /> 
    <LinearLayout 
     android:layout_width="match_parent" 
     android:layout_height="240dp" 
     android:orientation="vertical" 
     android:gravity="bottom" 
     android:layout_marginLeft="16dp" 
     android:id="@+id/container_layout"> 

    <FrameLayout 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:id="@+id/frameLayout_viewForFragments" /> 
    </LinearLayout> 
</android.support.v4.widget.DrawerLayout>

而且我mainActivity.cs文件：

using Android.App; 
using Android.Widget; 
using Android.OS; 
using Android.Support.V7.App; 
using Android.Views; 
using Android.Support.V4.Widget; 
using Android.Support.Design.Widget; 
using Android.Support.V4.View; 
// install from NuGet android.support.design 
// And App Compat support 
namespace App4 
{ 
    [Activity(Label = "TopSideBar App", MainLauncher = true , Icon = "@drawable/ic_launcher")] 
    public class MainActivity : AppCompatActivity 
    { 
     DrawerLayout m_drawerLayout; 
     NavigationView m_navigationView; 
     protected override void OnCreate(Bundle savedInstanceState) 
     { 
      base.OnCreate(savedInstanceState); 

      // Set our view from the "main" layout resource 
      SetContentView(Resource.Layout.Main); 

      SupportActionBar.Title = Resources.GetString(Resource.String.app_name); ; 


      m_drawerLayout = FindViewById<DrawerLayout>(Resource.Id.maintActivity_drawerlayout); 
      m_navigationView = FindViewById<NavigationView>(Resource.Id.maintActivity_navigationView); 
      m_navigationView.NavigationItemSelected += M_navigationView_NavigationItemSelected; 
      //Display sandwich menu icon 
      SupportActionBar.SetDisplayHomeAsUpEnabled(true); 
      SupportActionBar.SetHomeAsUpIndicator(Resource.Drawable.ic_menu_black_24dp_1x); 
      ConfigureNavigationViewHeader(); 

     } 

     private void ConfigureNavigationViewHeader() 
     { 
      View viewHeader = LayoutInflater.Inflate(Resource.Layout.mainActivity_navigationView_header, null); 

      ImageView imageviewUserAvatar = viewHeader.FindViewById<ImageView>(Resource.Id.mainActivity_navigationView_header_imageview_userAvatar); 
      TextView textviewUserPseudo = viewHeader.FindViewById<TextView>(Resource.Id.mainActivity_navigationView_header_textview_UserPseudo); 
      TextView textviewUserDesc = viewHeader.FindViewById<TextView>(Resource.Id.mainActivity_navigationView_header_textview_UserDesc); 

      imageviewUserAvatar.SetImageResource(Resource.Drawable.profile_pic); 
      textviewUserPseudo.Text = "Housma Mardini"; 
      textviewUserDesc.Text = "Web Developer"; 

      m_navigationView.AddHeaderView(viewHeader); 
     } 

     private void M_navigationView_NavigationItemSelected(object sender, NavigationView.NavigationItemSelectedEventArgs e) 
     { 

      switch (e.MenuItem.ItemId) 
      { 
       case Resource.Id.leftmenu_profile: 
        Toast.MakeText(this, "profile", ToastLength.Short).Show(); 
        m_drawerLayout.CloseDrawer(GravityCompat.Start); 
        break; 

       case Resource.Id.leftmenu_shopping_list: 
        break; 

       case Resource.Id.leftmenu_favorites: 
        break; 

       case Resource.Id.leftmenu_params_option: 
        break; 

       case Resource.Id.leftmenu_params_about: 
        break; 
      } 


     } 

     public override bool OnCreateOptionsMenu(Android.Views.IMenu menu) 
     { 
      MenuInflater.Inflate(Resource.Menu.top_menus, menu); 
      return base.OnCreateOptionsMenu(menu); 
     } 

     public override bool OnOptionsItemSelected(IMenuItem item) 
     { 
      switch (item.ItemId) 
      { 
       case Resource.Id.share: 
        Toast.MakeText(this , "Share" ,ToastLength.Short).Show(); 
        break; 

       case Resource.Id.moreoption: 
        Toast.MakeText(this, "Settings", ToastLength.Short).Show(); 


       break; 

       //Handle sandwich menu icon click 
       case Android.Resource.Id.Home: 
        //If menu is open, close it. Else, open it. 
        if (m_drawerLayout.IsDrawerOpen(GravityCompat.Start)) 
         m_drawerLayout.CloseDrawers(); 
        else 
         m_drawerLayout.OpenDrawer(GravityCompat.Start); 
        break; 
      } 

      return base.OnOptionsItemSelected(item); 
     } 
    } 
}

但是，當我從我的main.xml文件中刪除的LinearLayout和FrameLayout裏標籤的每一件事情進行得很好
