Java 将xml字符串数组中的项添加到片段中的回收器视图中

我在尝试将城市数组添加到片段列表中的每个项目位置时遇到了一些问题。我已经为我的片段创建了虚拟列表模板，但是在网上找不到任何关于如何将数组中的值存储在Strings.xml文件中的内容，这些内容包含在recycler视图中。我想用数组中的城市名称替换虚拟项（例如1:Item1、2:Item2等）。请帮忙

xml文件：

<resources>

    <string-array name="Cities">
        <item>Vancouver</item>
        <item>Kamloops</item>
        <item>Edmonton</item>
        <item>Calgary</item>
        <item>Winnipeg</item>
        <item>Toronto</item>
        <item>Montreal</item>
    </string-array>
</resources>

    View view = inflater.inflate(R.layout.fragment_cities_list, container, false);

    if (view instanceof RecyclerView) {
        Context context = view.getContext();

        //Get cities array from resource
        String[] cities = context.getResources().getStringArray(R.array.Cities);
        List<DummyItem> mValues = new ArrayList<>();
        for(int i = 0; i < cities.length; i++) {
            mValues.add(new DummyItem(String.valueOf(i + 1), cities[i], ""));
        }

        RecyclerView recyclerView = (RecyclerView) view;
        if (mColumnCount <= 1) {
            recyclerView.setLayoutManager(new LinearLayoutManager(context));
        } else {
            recyclerView.setLayoutManager(new GridLayoutManager(context, mColumnCount));
        }

        //Pass the mValues to adapter
        recyclerView.setAdapter(new MycitiesRecyclerViewAdapter(mValues, mListener));

，这是什么意思？我对“fragment\u Cities\u list.xml”中的移动设备不熟悉文件，什么是父视图？你能共享你的xml文件吗？是的，一秒钟很抱歉，我必须在评论中发布它，它不允许我编辑我的帖子，因此，这将进入适配器文件？是的，我正在试图弄清楚，它不起作用，因为有另一个我不知道的文件称为虚拟内容，它正在把它弄乱文件现在打开了吗ss empty到DummyItem，如
