In this article, we are going to learn how to create a simple ListView with item click in the Xamarin Android app.

Solution

Here are the steps required to create ListView in Xamarin Android app.

Step 1

Create/open your Android solution in Visual Studio or Xamarin Studio.

Step 2

Update your main.axml file inside your Resoursce/Layout folder, as shown below.

  1. <?xml version="1.0" encoding="utf-8"?>
  2. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent">
  3. <ListView android:id="@+id/mainlistview" android:layout_height="match_parent" android:layout_width="match_parent"> </ListView>
  4. </LinearLayout>

Step 3

Initialize ListView in MainActivity, as shown below.

  1. public class MainActivity: Activity {
  2. string[] items;
  3. ListView mainList;
  4. protected override void OnCreate(Bundle bundle) {
  5. base.OnCreate(bundle);
  6. items = new string[] {
  7. "Xamarin",
  8. "Android",
  9. "IOS",
  10. "Windows",
  11. "Xamarin-Native",
  12. "Xamarin-Forms"
  13. };
  14. // Set our view from the "main" layout resource
  15. SetContentView(Resource.Layout.Main);
  16. mainList = (ListView) FindViewById < ListView > (Resource.Id.mainlistview);
  17. mainList.Adapter = new ArrayAdapter(this, Android.Resource.Layout.SimpleListItem1, items);
  18. }
  19. }

Step 4

Initialize a ListView ItemClick event for handling the item click of ListView.

  1. mainList.ItemClick += (s, e) => {
  2. var t = items[e.Position];
  3. Android.Widget.Toast.MakeText(this, t, Android.Widget.ToastLength.Long).Show();
  4. };
Step 5

Now, run the application and you will see the output as given below.

Step 6

After clicking on ListView, the item toast message will display with title details.
