Let’s start,

Step 1: Open Visual Studio->New Project->Templates->Visual C#->Android->Blank App. Give the Project Name and Project Location.

Step 2 : Go to Solution Explorer-> Project Name-> Components, right click to Get More Components and the new dialog box opens. This dialog box is required to search the Support V4, add the Android Support Library V4 Packages.

Step 3: To open Solution Explorer, go to -> Project Name->Resources->layout ->Main.axml, click to open Design View and the code, given below,

<android.support.v4.widget.SwipeRefreshLayout 
android:id="@+id/swipeRefreshLayout" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:layout_above="@+id/btnaddnewmech" 
android:layout_alignParentTop="true"> 
<ListView 
android:minWidth="25px" 
android:minHeight="25px" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:id="@+id/listView1" /> 
</android.support.v4.widget.SwipeRefreshLayout>

Step 4: After Design view creation, open Solution Explorer-> Project Name->MainActivity.cs, add the namespaces, given below,

C# Code :

 using Android.Support.V4.Widget; 
 using Android.Graphics; 
 using System.Collections.Generic; 
 using System.ComponentModel; 
 using Java.Lang;

Step 5: To create the new variables for RefreshLayout and ListView, one can use the code, given below,

private SwipeRefreshLayout refreshLayout; 
private ListView listitem;

Step 6: Go to Oncreate() to declare the list view id and Listview<string>Variable.

Step 7: Next step is to create one List String Item and then add the list view adapter.

C# Code :

listitem = FindViewById < ListView > (Resource.Id.listView1); 
List < string > items = new List < string > (); 
items.Add("C#"); 
items.Add("ASP.NET"); 
items.Add("JAVA"); 
items.Add("MVC"); 
items.Add("Swift"); 
items.Add("JQuery"); 
items.Add("ASP"); 
items.Add("JSP"); 
items.Add("C"); 
items.Add("PHP"); 
items.Add("Ruby"); 
ArrayAdapter < string > liststring = new ArrayAdapter < string > (this, Android.Resource.Layout.SimpleExpandableListItem1, items); 
listitem.Adapter = liststring;

Step 8 : After Listview declaration, assign Refresh Layout variables and colors. Here, create one more method for Refresh event. This event is declared after Oncreate().

C# Code :

 refreshLayout = FindViewById < SwipeRefreshLayout > (Resource.Id.swipeRefreshLayout); 
 refreshLayout.SetColorSchemeColors(Color.Red, Color.Green, Color.Blue, Color.Yellow); 
 refreshLayout.Refresh += RefreshLayout_Refresh;

Step 9 : Declare RefreshLayout_refresh method. This method is working in the background process of the layout. Once the work completes, it will terminate the work.

C# Code :

 private void RefreshLayout_Refresh(object sender, EventArgs e) 
 { 
 //Data Refresh Place 
 BackgroundWorker work = new BackgroundWorker(); 
 work.DoWork += Work_DoWork; 
 work.RunWorkerCompleted += Work_RunWorkerCompleted; 
 work.RunWorkerAsync(); 
 } 
 private void Work_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) { 
 refreshLayout.Refreshing = false; 
 } 
 private void Work_DoWork(object sender, DoWorkEventArgs e) { 
 Thread.Sleep(1000); 
 }

Step 10: Press F5 or build and run the Application.

Finally, we successfully created Xamarin Android SwipeRefreshLayout with ListView items.
