ListFragment - 如何添加一个菜单？

问题描述

我有一个ListFragment，我不得不添加一个菜单。这是我的code：
listuser_menu：

I have a ListFragment and I have to add a menu. This is my code: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ListFragment：

My 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menu..why？如何Register选项菜单中选择？谢谢！

But i can't see my menu..why? How register option menu selected? Thanks!

推荐答案

添加菜单片段是可能的，请使用以下code在你的片段：

Adding menus to fragment is possible, use the following code in your Fragment:

@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将让您的片段显示一个菜单。

Using setHasOptionsMenu will allow your fragment to show a menu.
