C# Android.Views.InflateException:使用自定义按钮选择器对类Android.widget.Button进行充气时出错

我在另一个项目中遇到了一些问题，所以我创建了一个新的项目，看看我是否也遇到了同样的错误

我在main.axml中创建了一个按钮，我正在尝试使用somestyle.xml对其进行样式设置

somestyle.xml:

 <?xml version="1.0" encoding="utf-8" ?>
 <selector xmlns:android="http://schemas.android.com/apk/res/android">

  <!-- What to do when the button is NOT pressed -->
  <item android:state_pressed="false">

    <layer-list>
      <item android:right="5dp" android:top="5dp">

        <!-- Shape the button -->
        <corners android:radius="20dp"/>
        <solid android:color="#d13838"/>

      </item>


      <item android:bottom="2dp" android:left="2dp">
        <shape>
          <gradient android:angle="270" android:endColor="#d13838" android:startColor="#d13838"/>
          <stroke android:width="1dp" android:color="#d13838"/>
          <corners android:radius="4dp"/>
          <padding android:bottom="0dp" android:left="10dp" android:right="10dp" android="10dp"/>
        </shape>
      </item>
    </layer-list>

  </item>

</selector>

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <Button
        android:id="@+id/btn"
        android:text="Btn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:background="@drawable/somestyle" />
</LinearLayout>

using Android.App;
using Android.Widget;
using Android.OS;

namespace TestNamespaceBug
{
    [Activity(Label = "TestNamespaceBug", MainLauncher = true, Icon = "@drawable/icon")]
    public class MainActivity : Activity
    {
        protected override void OnCreate(Bundle bundle)
        {
            base.OnCreate(bundle);

            // Set our view from the "main" layout resource
            SetContentView (Resource.Layout.Main);
        }
    }

我不知道是什么导致了所有的警告和异常。非常感谢您对如何解决此问题提出的任何建议。

我确实认为您的“塑造按钮”项目遗漏了一个

无法相信它是如此愚蠢的事情，谢谢！你知道这些警告是怎么回事吗？我从来没有用过Xamarin，所以不，我没有：）
