In this tutorial, I will show you how to bind array list into spinner in android apps using c sharp with Xamarin. Spinner is a widget similar to a drop-down list.
Follow these steps to display an array of string in a spinner.
- Create new Project
- Expand resource folder
- Click on layout folder
- Open layout Main.axml and paste below code
<?xml version=“1.0“ encoding=“utf-8“?>
<LinearLayout xmlns:android=“http://schemas.android.com/apk/res/android“
android:orientation=“vertical“
android:padding=“10dip“
android:layout_width=“fill_parent“
android:layout_height=“wrap_content“>
<TextView
android:layout_width=“fill_parent“
android:layout_height=“wrap_content“
android:layout_marginTop=“10dip“
android:text=“@string/spinner1“ />
<Spinner
android:layout_width=“match_parent“
android:layout_height=“61.0dp“
android:id=“@+id/spinner1“ />
</LinearLayout>
Open MainActivity.cs
In MainActivity create ItemSelected event .overriding ItemSelected allows us to handle item selection.
MainActivity.cs
public class MainActivity : Activity
{
private List<string>Mlist;
private Spinner spinner;
protected override voidOnCreate(Bundle bundle)
{
base.OnCreate(bundle);
// Set our view from the “main” layout resource
SetContentView (Resource.Layout.Main);
Mlist = new List<string>();
Mlist.Add(“Sunday”);
Mlist.Add(“Monday”);
Mlist.Add(“Tuesday”);
Mlist.Add(“Wednesday”);
Mlist.Add(“Thursday”);
Mlist.Add(“Friday”);
Mlist.Add(“Saturday”);
spinner = FindViewById<Spinner>(Resource.Id.spinner1);
ArrayAdapter adapter =new ArrayAdapter(this, Android.Resource.Layout.SimpleSpinnerItem,Mlist);
adapter.SetDropDownViewResource(Android.Resource.Layout.SimpleSpinnerDropDownItem);
spinner.Adapter = adapter;
spinner.ItemSelected += spinner_Click;
}
private voidspinner_Click(object sender, AdapterView.ItemSelectedEventArgs e)
{
Toast.MakeText(this, “Selected Day “ + spinner.GetItemAtPosition(e.Position), ToastLength.Short).Show();
}
}
}
