Xamarin Android綁定類FooInvoker沒有實現接口設置器

Question

我有一個Xamarin Android綁定錯誤，沒有任何意義！

生成的類存根：

[global::Android.Runtime.Register ("com/scichart/drawing/common/IRenderSurface", DoNotGenerateAcw=true)] 
internal class IRenderSurfaceInvoker : global::Java.Lang.Object, IRenderSurface 


[Register ("com/scichart/drawing/common/IRenderSurface", "", "Com.Scichart.Drawing.Common.IRenderSurfaceInvoker")] 
public partial interface IRenderSurface : global::Com.Scichart.Core.Framework.IInvalidatableElement, global::Com.Scichart.Core.Framework.IView { } 

// Metadata.xml XPath interface reference: path="/api/package[@name='com.scichart.core.framework']/interface[@name='IView']" 
[Register ("com/scichart/core/framework/IView", "", "Com.Scichart.Core.Framework.IViewInvoker")] 
public partial interface IView : global::Com.Scichart.Core.Framework.IContextProvider, global::Com.Scichart.Core.Framework.IHitTestable 
{ 

    int Visibility 
    { 
     // Metadata.xml XPath method reference: path="/api/package[@name='com.scichart.core.framework']/interface[@name='IView']/method[@name='getVisibility' and count(parameter)=0]" 
     [Register ("getVisibility", "()I", "GetGetVisibilityHandler:Com.Scichart.Core.Framework.IViewInvoker, SciChart.Android.Core")] get; 
     // Metadata.xml XPath method reference: path="/api/package[@name='com.scichart.core.framework']/interface[@name='IView']/method[@name='setVisibility' and count(parameter)=1 and parameter[1][@type='int']]" 
     [Register ("setVisibility", "(I)V", "GetSetVisibility_IHandler:Com.Scichart.Core.Framework.IViewInvoker, SciChart.Android.Core")] set; 
    } 
} 

發生了什麼事是IView.Visibility（已獲取，設置）與基類Android.View.Visibility衝突。我已經在附加文件夾中解決了衝突，但是有這個IRenderSurfaceInvoker類生成，而不是部分，並且沒有正確實現IView接口。

一般情況下我忽略metadata.xml中的屬性，並以部分類手動創建它，但這是不可能的，因爲IRenderSurfaceInvoker不是局部的。

無論如何什麼是FooInvoker ??！

任何想法？ :)

編輯：UPDATE

以下後，斯文邁克爾的Stube的回答，我有這部分解決方案：

<!-- In EnumMethods.xml --> 
<mapping jni-interface="com/scichart/core/framework/IView"> 
    <method jni-name="getVisibility" parameter="return" clr-enum-type="Android.Views.ViewStates" /> 
    <method jni-name="setVisibility" parameter="visibility" clr-enum-type="Android.Views.ViewStates" /> 
</mapping> 

但是這導致的iView界面生成如下：

global::Android.Views.ViewStates Visibility { 
     // Metadata.xml XPath method reference: path="/api/package[@name='com.scichart.core.framework']/interface[@name='IView']/method[@name='getVisibility' and count(parameter)=0]" 
     [Register ("getVisibility", "()I", "GetGetVisibilityHandler:Com.Scichart.Core.Framework.IViewInvoker, SciChart.Android.Core")] get; 
    } 

和警告輸出

<attr path="/api/package[@name='com.scichart.core.framework']/interface[@name='IView']‌​/method[@name='setVisibility']/parameter[@name='visibility']"/> matched no nodes 

換句話說，上面的EnumMethods.xml聲明刪除了setter，因爲它找不到匹配項。

我該如何調試？

我認爲你不必解決你的View vs IView問題。您應該覆蓋獲取方的返回值和設置器的參數Android.Views.ViewStates in EnumMethods.xml。這個可能解決你的問題，如果你一直這樣做。

<mapping jni-interface="com/scichart/core/framework/IView"> 
    <method jni-name="getVisibility" parameter="return" clr-enum-type="Android.Views.ViewStates" /> 
    <method jni-name="setVisibility" parameter="p0" clr-enum-type="Android.Views.ViewStates" /> 
</mapping>
