Невозможно использовать AppCompat управления в проекте Xamarin

Question

Я пытался использовать компоненты AppCompat в моей Android Application, но по какой-то метод причина SetContentView продолжает бросать:

Android.Views.InflateException: Binary XML file line #1: Binary XML file line #1: Error inflating class android.support.design.widget.TextInputLayout

активность наследуется правильный класс и используя правильную тему (AFAIK) (Я попытался с помощью «@android: стиль/Theme.AppCompat» а)

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

Ниже приведены ссылки на проекты и их компоненты.

Я что-то не хватает? Есть идеи?

EDIT

Вот мой макет XML:

вот мой 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.Vector.Drawable" version="23.4.0.1" targetFramework="monoandroid60" /> 
</packages> 

Код, который бросает исключение:

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(); 
}

Ошибка заключается в следующем:

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

ли Android Поддержка библиотека дизайн, на Вашем случае, Вы не хватает, что библиотеки на вашем Папка пакета на основе скриншотов вашего проекта. Добавление этого Android Support Design Library решит проблему. Установите, закройте VS, очистите восстановление и увидите, что ошибка все еще сохраняется. Ура!
