如何实现searchview来过滤资源字符串值（整数）中的arraylist？

Question

我如何用源自值字符串的arraylist创建一个listview过滤器，这可能吗？ 。我按照本教程进行操作，仅发现在数组列表模型中直接从字符串而不是整数（资源字符串）编写的源代码

问题在于，在过滤器中实现toLowerCase与整数不匹配。

请帮助我，对不起我的英语不好

这是我的代码

public class SearchBox extends Fragment {
public static List<DaftarList> daftarLists;
ListView listView;
ImageView imageView;
SearchView searchView;
TextView textView;


@Override
public View onCreateView(final LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    final View rootview = inflater.inflate(R.layout.navigasi_searchbox, container, false);
    findViewsById(rootview);
    setProducts();
    ListViewAdapter listViewAdapter = new ListViewAdapter(getActivity(), R.layout.daftarlistview, daftarLists);
    listView.setAdapter(listViewAdapter);
    imageView = (ImageView) rootview.findViewById(R.id.gambar);
    textView = rootview.findViewById(R.id.tv_search);
    searchView = rootview.findViewById(R.id.searchView);

    listView.setVisibility(View.GONE);

    searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String query) {
            return false;
        }

        @Override
        public boolean onQueryTextChange(String newText) {
            ListViewAdapter listViewAdapter = new ListViewAdapter(getActivity(), R.layout.daftarlistview, daftarLists);
            listView.setAdapter(listViewAdapter);


            if (TextUtils.isEmpty(newText)) {
                listViewAdapter.getFilter().filter("");
                //     listView.clearTextFilter();
                listView.setVisibility(View.GONE);
                listView.setVisibility(View.INVISIBLE);
                textView.setVisibility(View.VISIBLE);

                return true;

            } else {
                listViewAdapter.getFilter().filter(newText);
                listView.setVisibility(View.VISIBLE);
                textView.setVisibility(View.INVISIBLE);

            }
            return true;
        }

    });


    return rootview;
