Introduction

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.

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

Step 3

Initialize ListView in MainActivity, as shown below.

public class MainActivity: Activity {
    string[] items;
    ListView mainList;
    protected override void OnCreate(Bundle bundle) {
        base.OnCreate(bundle);
        items = new string[] {
            "Xamarin",
            "Android",
            "IOS",
            "Windows",
            "Xamarin-Native",
            "Xamarin-Forms"
        };
        // Set our view from the "main" layout resource
        SetContentView(Resource.Layout.Main);
        mainList = (ListView) FindViewById < ListView > (Resource.Id.mainlistview);
        mainList.Adapter = new ArrayAdapter(this, Android.Resource.Layout.SimpleListItem1, items);
    }
}

Step 4

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

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

Step 5

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

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