android - Android 上下文菜单创建中的 getMenuInflater() 方法未定义问题

Question

我正在尝试在 fragment 中创建上下文菜单项。但是我遇到了 getMenuInflater() 方法的问题。它是未定义的。我已经导入了所有必要的包。谁能指出我在这里做错了什么？

这是我的代码:

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.ContextMenu;
import android.view.ContextMenu.ContextMenuInfo;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.MenuInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import android.view.MenuItem;

public class FeaturedFragment extends Fragment {
    public FeaturedFragment() {
    }
    public static final String ARG_SECTION_NUMBER = "section_number";

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.featured_fragment,container,false);
        registerForContextMenu(view);
        return view;
    }

    @Override
    public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo)
    {
        super.onCreateContextMenu(menu, v, menuInfo);
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.toggleview_menu, menu);
    }
}

这是我的 menu.xml

  <menu xmlns:android="http://schemas.android.com/apk/res/android" >    
      <item android:id="@+id/toggle_view"
         android:title="Change to ListView"
         android:icon="@drawable/collections_view_as_grid"
         android:showAsAction="always" />
      <item android:id="@+id/grid_view"
         android:title="Grid View"
         android:orderInCategory="99"
         android:showAsAction="never" />
      <item android:id="@+id/list_view"
         android:title="List View"
         android:orderInCategory="99"
         android:showAsAction="never" />
  </menu>

变化:

MenuInflater inflater = getMenuInflater();

到这里:

MenuInflater inflater = getActivity().getMenuInflater();
