How to put items in a Listview

The add method does not appear, I'm new so I have no idea what it can be

   protected override void OnCreate(Bundle bundle)
    {
        base.OnCreate(bundle);

        // Set our view from the "main" layout resource
        SetContentView(Resource.Layout.Main);

        ListView lista = FindViewById<ListView>(Resource.Id.listView1);
        lista.Add();

    }
