ClassNotFoundException Mvx.MvxListView

I'm trying use MvxListView with MvxAppCompatActivity, but I always get:

InflateException: Error inflating class Mvx.MvxListView ClassNotFoundException: Didn't find class "Mvx.MvxListView

Here is my axml:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res/com.viniciusmaia.missaocarona"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <include
        layout="@layout/Toolbar" />

    <Mvx.MvxListView
        android:id="@+id/teste"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        app:MvxBind="ItemsSource Usuarios;ItemClick UsuarioClickCommand"
        app:MvxItemTemplate="@layout/usuarioitem"/>
</LinearLayout>

Here is my Activity:

[Activity] 
public class UsuarioActivity : MvxAppCompatActivity<UsuarioViewModel>
{
    protected override void OnCreate(Bundle savedInstanceState)
    {
        base.OnCreate(savedInstanceState);

        SetContentView(Resource.Layout.UsuarioView);            

        var toolbar = FindViewById<Android.Support.V7.Widget.Toolbar>(Resource.Id.toolbar);

        toolbar.Title = UsuarioMensagens.TITULO_Usuario;

        //SetSupportActionBar(toolbar);

        Window.AddFlags(WindowManagerFlags.DrawsSystemBarBackgrounds);

        ViewModel.Carregamento = new Carregamento(this);
        ViewModel.PreenchePagina();
    }
}

I tried use Mvx.MvxListview and MvxListView like this post Binary XML file line #1: Error inflating class Mvx.MvxListView, but nothing works for me.

Can anyone help me?

Mvx.MvxListView mentioned in Alex's answer is a shortcut that is registered with the custom Inflater that does binding in MvvmCross. This means, if your Setup class does not tell where to look for Mvx, the shortcuts wont work.

In this case, I see you are using MvxAppCompatActivity, which comes from one of the Support packages. There is a separate Setup you inherit from there, which handles a lot of registration for you. It will also set up some tint aware views.

So in your Setup, you should inherit from MvxAppCompatSetup:

public class Setup : MvxAppCompatSetup
{
}

This should be enough to find Mvx.MvxListView. If it doesn't you can try adding more abbreviations by overriding ViewNamespaceAbbreviations in your Setup:

public class Setup : MvxAppCompatSetup
{
    ...

    protected override IDictionary<string, string> ViewNamespaceAbbreviations new Dictionary<string, string>
    {
        {"Mvx", "MvvmCross.Binding.Droid.Views"},
        {"MyViews", "My.Custom.Views"},
        // add more abbreviations here
    };
}

This will make MvvmCross look for views in MvvmCross.Binding.Droid.Views when you prefix them with Mvx in your axml files.

"Mvx" => "MvvmCross.Binding.Droid.Views" is a default one, and should work with any BindingInflater from both MvxAppCompatSetup, but also MvxAndroidSetup.

Try replacing this line on your LinearLayout

xmlns:app="http://schemas.android.com/apk/res/com.viniciusmaia.missaocarona"

with this:

xmlns:app="http://schemas.android.com/apk/res-auto"

Try writing Mvx.MvxListView in your axml file instead of MvxListView.

Also your xmlns:app="http://schemas.android.com/apk/res/com.viniciusmaia.missaocarona" should be actually xmlns:app="http://schemas.android.com/apk/res-auto".

One more thing to double check is to make sure your Setup class derives from MvxAndroidSetup
