Question

我在Xamarin.Android解决方案中创建了以下片段：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using Android.Content;
using Android.OS;
using Android.Runtime;
using Android.Util;
using Android.Views;
using Android.Widget;
using MvvmCross.Binding.Droid.Views;
using MvvmCross.Binding.Droid.BindingContext;

using ActiveNomad.Droid.Models;
using ActiveNomad.Droid.Settings;
using Android.Support.V4.App;
using MvvmCross.Droid.ViewModels;

namespace ActiveNomad.Droid.Views
{
[Register("activenomad.droid.views.adpagefragment")]
public class AdPageFragment : Fragment
{
    ImageView sponsorImageView;
    VideoView videoView;

    protected override void OnCreate (Bundle bundle)
    {
        base.OnCreate (bundle);

    }

    protected override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
        base.OnCreateView (inflater, container, savedInstanceState);
        ActiveNomadSettings settings = SettingsManager.Instance.GetSettings ();

        sponsorImageView.FindViewById<ImageView> (Resource.Id.sponsorlogo);
        Android.Net.Uri imgUri = Android.Net.Uri.Parse (settings.SponsorImagePath);
        sponsorImageView.SetImageURI (imgUri);

        videoView.FindViewById<VideoView> (Resource.Id.AdVideo);
        Android.Net.Uri vidUri = Android.Net.Uri.Parse (settings.AdPageVideoPath);
        videoView.SetVideoURI (vidUri);
        videoView.Start ();

        return inflater.Inflate (Resource.Layout.AdPageView, container, true);

    }


  }
}

我的活动如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

using Android.App;
using Android.Content;
using Android.OS;
using Android.Runtime;
using Android.Views;
using Android.Widget;
using Android.Support.V4.App;
using ActiveNomad.Droid.Views;

namespace ActiveNomad
{
[Activity (Label = "AdPageActivity")]           
public class AdPageActivity : FragmentActivity
{
    protected override void OnCreate (Bundle bundle)
    {
        base.OnCreate (bundle);

        var ad = new AdPageFragment{Arguments = new Bundle()};
        var fragmentTransaction = SupportFragmentManager.BeginTransaction ();
        fragmentTransaction.Add (Android.Resource.Id.Content, ad);
        fragmentTransaction.Commit ();
    }
 }
}

我更改了片段，使OnCreateView现在成为公共覆盖。但是，抛出了一个新错误：

  Error:  error: class adpagefragment is public, should be declared in   
  a file named adpagefragment.java

Xamarin Studio打开java文件但不确定这是否是系统生成的，以及是否应该修改它。该问题应如何解决？

将OnCreateView方法从protected更改为public。 public上的Fragment，如错误消息中所述，您无法将访问修饰符更改为protected。

public override View OnCreateView(LayoutInflater inflater, ViewGroup container,
       Bundle savedInstanceState)
