不能使用程序兼容性控制在Xamarin項目

Question

我一直想在我的Android應用程序使用程序兼容性組件，但由於某些原因的setContentView方法不斷拋出：

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

活動的繼承權類，並且是使用權主題（據我所知）（我已經嘗試使用「@android：風格/ Theme.AppCompat」以及）

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

這裏有（相關）項目引用和組件。

我這麼想嗎？有任何想法嗎？

編輯

這裏是我的佈局XML：

這裏是我的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.Vector.Drawable" version="23.4.0.1" targetFramework="monoandroid60" /> 
</packages> 

代碼拋出異常：

個

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(); 
} 

包 組件

Answer 1

的錯誤是：

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

是一個支持Android的設計庫，在你的情況，你缺少一個庫您打包文件夾基於您的項目的屏幕截圖。添加這個Android Support Design Library可以解決問題。安裝，關閉VS，清理重建並查看錯誤仍然存​​在。乾杯!
