Aktivität ist richtige Klasse vererben und wird mit Recht Theme (AFAIK) (ich habe versucht mit "@android: Stil/Theme.AppCompat" auch)

[Activity(Label = "AttendIT Mobile", MainLauncher = true, Icon = "@drawable/icon", Theme = "@style/Theme.AppCompat")] 
public class LoginActivity : AppCompatActivity 

Hier sind (relevante) Projektreferenzen und Komponenten.

Fehle ich etwas? Irgendwelche Ideen?

EDIT

Hier ist mein Layout xml:

hier ist mein packages.config

<?xml version="1.0" encoding="utf-8"?> 
<packages> 
    <package id="Refractored.FloatingActionButton" version="1.3.0" targetFramework="monoandroid60" /> 
    <package id="Xamarin.Android.Support.Animated.Vector.Drawable" version="23.4.0.1" targetFramework="monoandroid60" /> 
    <package id="Xamarin.Android.Support.v4" version="23.4.0.1" targetFramework="monoandroid60" /> 
    <package id="Xamarin.Android.Support.v7.AppCompat" version="23.4.0.1" targetFramework="monoandroid60" /> 
    <package id="Xamarin.Android.Support.v7.RecyclerView" version="22.0.0.0" targetFramework="monoandroid60" /> 
    <package id="Xamarin.Android.Support.Vector.Drawable" version="23.4.0.1" targetFramework="monoandroid60" /> 
</packages> 

Code, der Ausnahme wirft:

private void Initialize() 
{ 

    SetContentView(Resource.Layout.Login); //this method throws exception 



    Button button = FindViewById<Button>(Resource.Id.LoginButton); 
    button.Click += LoginButtonOnClick; 

    TextView textView = FindViewById<TextView>(Resource.Id.Settings); 
    textView.Click += SettingsOnClick; 

    _loginLoader = new ProgressDialog(this); 
    _loginLoader.SetCancelable(false); 
    _loginLoader.SetMessage(Resources.GetString(Resource.String.LoginLoaderMessage)); 

    TimeSpan timeout = new TimeSpan(0, 0, 30); 
    BasicHttpBinding binding = new BasicHttpBinding 
    { 
     Name = "basicHttpBinding", 
     MaxBufferSize = 2147483647, 
     MaxReceivedMessageSize = 2147483647, 
     SendTimeout = timeout, 
     OpenTimeout = timeout, 
     ReceiveTimeout = timeout 
    };  
    _client = new AttendITWCFServiceClient(binding, new EndpointAddress("http://192.168.1.104:55416/AttendITWCFService.svc")); 
    _client.TryLoginCompleted += ClientOnTryLoginCompleted; 
} 

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

Pakete Komponenten

Answer 1

Der Fehler ist, dass:

java.lang.ClassNotFoundException: Didn't find class "android.support.design.widget.TextInputLayout" 

Ist ein Android Support-Design-Bibliothek, auf Ihrem Fall, Sie sind auf Ihrer dass Bibliothek fehlt Paketordner basierend auf den Screenshots Ihres Projekts. Hinzufügen dieses Android Support Design Library würde das Problem lösen. Installieren Sie, schließen Sie VS, säubern Sie die Neuerstellung, und sehen Sie, dass der Fehler weiterhin besteht. Prost!
