getMenuInflater( ) method undefined issue in Android Context Menu creation
提问by intrepidkarthi
I am trying to create a context menu item inside a fragment. But I am facing issue with the getMenuInflater() method. It is undefined. I have imported all the necessary packages. Can anyone point out what I am doing wrong here?
我正在尝试在片段中创建一个上下文菜单项。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？

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);
}

Change:
改变：
MenuInflater inflater = getMenuInflater();
To this:
对此：
MenuInflater inflater = getActivity().getMenuInflater();
