ListFragment - 如何添加菜单？

Question

我有一个ListFragment,我必须添加一个菜单.这是我的代码:listuser_menu:

<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
    android:id="@+id/any_option"
    android:title="In Context Menu" />
</menu>

我的ListFragment:

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    View mFooterView;
    // We need to use a different list item layout for devices older than Honeycomb
    int layout = Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB ?
    android.R.layout.simple_list_item_activated_1:android.R.layout.simple_list_item_1;
    if(getListAdapter()==null){
        // init adapter
        adapter=new UserArrayAdapter(getActivity(),
                MOBILE_OS);
    }
    else{
            adapter.notifyDataSetChanged(); 
        } 

    // set adapter
    registerForContextMenu(getListView());
    setListAdapter(adapter);

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

但我看不到我的菜单..为什么？如何选择注册选项菜单？谢谢!

Answer 1

可以在片段中添加菜单,在片段中使用以下代码:

@Override
public void onActivityCreated(Bundle savedInstanceState) {
setHasOptionsMenu(true);

}

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
inflater.inflate(R.menu.listuser_menu, menu);
}

使用setHasOptionsMenu将允许您的片段显示菜单.
