Step 7: We need dimensions for the card view margin.  Go to Solution Explorer-> Project Name->Resources->values. Right click to Add->New Item, open new dialog box. Select XML file and give the name for dimens.xml.

Step 8: Open Solution Explorer-> Project Name->Resources->values->colors.xml. Click to open Design View and the code, given below,

<?xml version="1.0" encoding="utf-8" ?> 
<resources> 
 <color name="ColorPrimary">#2196F3</color> 
 <color name="ColorPrimaryDark">#1976D2</color> 
</resources>

Step 9: Open Solution Explorer-> Project Name->Resources->values->styles.xml. Click to open Design View and the code, given below,

 <?xml version="1.0" encoding="utf-8" ?> 
 <resources> 
 <style name="Theme.DesignDemo" parent="Base.Theme.DesignDemo"> 
 
 </style> 
 <style name="Base.Theme.DesignDemo" parent="Theme.AppCompat.Light.NoActionBar"> 
 <item name="colorPrimary">@color/ColorPrimary</item> <item name="colorPrimaryDark">@color/ColorPrimaryDark</item>

 <style name="Widget.CardContent" parent="android:Widget"> 
 <item name="android:paddingLeft">16dp</item> <item name="android:paddingRight">16dp</item> <item name="android:paddingTop">24dp</item> <item name="android:paddingBottom">24dp</item> <item name="android:orientation">vertical</item> 
 </style> 
 </resources>

Step 10: Open Solution Explorer-> Project Name->Resources->values->dimens.xml. Click to open Design View and the code, given below,

 <resources> 
 <dimen name="drawer_width">240dp</dimen> 
 <dimen name="detail_backdrop_height">256dp</dimen> 
 <dimen name="card_margin">16dp</dimen> 
 <dimen name="fab_margin">16dp</dimen> 
 <dimen name="list_item_avatar_size">40dp</dimen> 
 </resources>

Step 11: Open Solution Explorer-> Project Name->Resources->layout ->Main.axml. Click to open Design View and the code, given below,

<?xml version=”1.0″ encoding=”utf-8″?>
<android.support.design.widget.CoordinatorLayout xmlns:android=”http://schemas.android.com/apk/res/android” xmlns:app=”http://schemas.android.com/apk/res-auto” android:id=”@+id/main_content” android:layout_width=”match_parent” android:layout_height=”match_parent” android:fitsSystemWindows=”true”>

<android.support.v4.widget.NestedScrollView android:layout_width=”match_parent” android:layout_height=”match_parent” app:layout_behavior=”@string/appbar_scrolling_view_behavior”>
<LinearLayout android:layout_width=”match_parent” android:layout_height=”match_parent” android:orientation=”vertical” android:paddingTop=”24dp”>
<android.support.v7.widget.CardView android:layout_width=”match_parent” android:layout_height=”wrap_content” android:layout_marginBottom=”@dimen/card_margin” android:layout_marginLeft=”@dimen/card_margin” android:layout_marginRight=”@dimen/card_margin”>
<LinearLayout style=”@style/Widget.CardContent” android:layout_width=”match_parent” android:layout_height=”wrap_content”>
<TextView android:layout_width=”match_parent” android:layout_height=”wrap_content” android:text=”NAME” android:textAppearance=”@style/TextAppearance.AppCompat.Title” />
<TextView android:layout_width=”match_parent” android:layout_height=”wrap_content” android:text=”Anbu M” /> </LinearLayout>
</android.support.v7.widget.CardView>
<android.support.v7.widget.CardView android:layout_width=”match_parent” android:layout_height=”wrap_content” android:layout_marginBottom=”@dimen/card_margin” android:layout_marginLeft=”@dimen/card_margin” android:layout_marginRight=”@dimen/card_margin”>
<LinearLayout style=”@style/Widget.CardContent” android:layout_width=”match_parent” android:layout_height=”wrap_content”>
<TextView android:layout_width=”match_parent” android:layout_height=”wrap_content” android:text=”PLACE” android:textAppearance=”@style/TextAppearance.AppCompat.Title” />
<TextView android:layout_width=”match_parent” android:layout_height=”wrap_content” android:text=”India” /> </LinearLayout>
</android.support.v7.widget.CardView>
<android.support.v7.widget.CardView android:layout_width=”match_parent” android:layout_height=”wrap_content” android:layout_marginBottom=”@dimen/card_margin” android:layout_marginLeft=”@dimen/card_margin” android:layout_marginRight=”@dimen/card_margin”>

</android.support.v7.widget.CardView>
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
</android.support.design.widget.CoordinatorLayout>

Step 12: After Design view creation, open Solution Explorer-> Project Name->MainActivity.cs and the steps, given below:

Step 13: Add Namespaces, given below,

using Android.Support.V7.App; 
using Android.Support.Design.Widget; 
using V7Toolbar = Android.Support.V7.Widget.Toolbar;

Step 14: Create ViewPager variable. Declare the viewpager within the OnCreate().before to change to the Activity to AppCompatActivity.

 

C# Code :

public class MainActivity: AppCompatActivity 
 { 
 protected override void OnCreate(Bundle bundle) 
 { 
 base.OnCreate(bundle); 
 // Set our view from the "main" layout resource 
 SetContentView(Resource.Layout.Main); 
 var toolbar = FindViewById < V7Toolbar > (Resource.Id.toolbar); 
 SetSupportActionBar(toolbar); 
 SupportActionBar.SetDisplayHomeAsUpEnabled(true); 
 var collapsingToolbar = FindViewById < CollapsingToolbarLayout > (Resource.Id.collapsing_toolbar); 
 collapsingToolbar.Title = "WHO I AM?"; 
 } 
 }

Step 15: Press F5 or build and run the Application.

Finally, we successfully created Xamarin Android CollapsingToolbarLayout, NestedScrollView, CardView, using XamarinAndroidSupportDesign.
