Question

我一直在尝试在我的Android应用程序中使用AppCompat组件，但由于某种原因，SetContentView方法不断抛出：

Android.Views.InflateException：二进制XML文件行＃1：二进制XML 文件行＃1：错误膨胀类 android.support.design.widget.TextInputLayout

异常的堆栈跟踪：

活动是继承正确的类，并使用正确的主题（AFAIK）（我已尝试使用＆＃34; @android：style / Theme.AppCompat＆＃34;以及）

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

以下是（相关的）项目参考和组件。

我错过了什么吗？有什么想法吗？

修改

这是我的布局xml：

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="fill_parent"

    android:paddingRight="24dp">

        android:layout_marginBottom="24dp"
        android:layout_gravity="center_horizontal" />
    <android.support.design.widget.TextInputLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="8dp"
        android:layout_marginBottom="8dp">
        <EditText
            android:id="@+id/UsernameEdit"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:inputType="textEmailAddress"
            android:hint="Email" />

        android:layout_marginBottom="8dp">

            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:inputType="textPassword"
            android:hint="Password" />
    </android.support.design.widget.TextInputLayout>
    <android.support.v7.widget.AppCompatButton

        android:layout_marginTop="24dp"
        android:layout_marginBottom="24dp"
        android:padding="12dp"
        android:text="Login"/>
    <TextView
        android:id="@+id/Settings"

        android:text="No account yet? Create one"
        android:gravity="center"
        android:textSize="16dip" />
 </LinearLayout>

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

抛出异常的代码：

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();
}

包组件

Answer 1

错误是：

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

Android支持设计库，根据您的情况，您在打包文件夹上缺少基于项目屏幕截图的库。添加此Android Support Design Library可以解决问题。安装，关闭VS，清理重建并查看错误仍然存在。干杯！

无法在Xamarin项目
