Adding the View class

As I mentioned, we have added the ViewModel and the View, but we did not link them together. Now create a new folder called Views in the root folder of the MvvmCrossDemo.Droid project and add a class called FirstView.cs in the Views folder, as shown below:

using Android.App;
using Android.OS;
using MvvmCross.Platforms.Android.Presenters.Attributes;
using MvvmCross.Platforms.Android.Views;

namespace MvvmCrossDemo.Droid.Views
{
    [MvxActivityPresentation]
    [Activity(Label = "First View")]
    public class FirstView : MvxActivity
    {
        protected override void OnCreate(Bundle bundle)
        {
            base.OnCreate(bundle);
            SetContentView(Resource.Layout.FirstView);
        }
    }
}

Make sure the FirstView inherits from the MvxActivity class. Now MvvmCross will help us build the connection between the View and the ViewModel.

Test the Android project on the phone. We should see the application like this:
