在android中搜索过滤器

Question

我有一个代码可以在android中的字典应用程序的listview中显示搜索菜单​​的结果，代码可以显示与我在搜索中输入的查询相同的结果。我需要显示包含查询的所有单词，而不仅仅是同一个单词。这是我的代码：

public class ItemListBaseAdapter extends BaseAdapter implements Filterable {
private Context contex;
private static List<Word> original_items = new ArrayList<>();
private static List<Word> filtered_items = new ArrayList<>();

private ItemFilter mFilter = new ItemFilter();
private LayoutInflater l_Inflater;

public ItemListBaseAdapter(Context context, List<Word> results) {
    this.contex=context;
    original_items = results;
    filtered_items = results;
    l_Inflater = LayoutInflater.from(context);
}

public Filter getFilter() {
    return mFilter;
}

public int getCount() {
    return filtered_items.size();
}

public Object getItem(int position) {
    return filtered_items.get(position);
}

public long getItemId(int position) {
    return position;
}

public View getView(int position, View convertView, ViewGroup parent) {
    ViewHolder holder;
    if (convertView == null) {
        convertView = l_Inflater.inflate(R.layout.list_item, null);
        holder = new ViewHolder();
        holder.txt_word = (TextView) convertView.findViewById(R.id.textView1);
        holder.txt_result= (TextView) convertView.findViewById(R.id.textView2);
        convertView.setTag(holder);
    } else {
        holder = (ViewHolder) convertView.getTag();
    }

    holder.txt_word.setText(filtered_items.get(position).getWord());
    holder.txt_result.setText(filtered_items.get(position).getResult());
    return convertView;
}

static class ViewHolder {
    TextView txt_word;
    TextView txt_result;
}


private class ItemFilter extends Filter {
    @Override
    protected FilterResults performFiltering(CharSequence constraint) {
        String query = constraint.toString().toLowerCase();

        FilterResults results = new FilterResults();
        final List<Word> list = original_items;
        final List<Word> result_list = new ArrayList<>(list.size());

        for (int i = 0; i < list.size(); i++) {
            String str_word = list.get(i).getWord();
            String str_res = list.get(i).getResult();

            if (str_word.toLowerCase().contains(query) || str_res.toLowerCase().contains(query)) {
                result_list.add(list.get(i));
            }
        }

        results.values = result_list;
        results.count = result_list.size();

        return results;
    }

    @SuppressWarnings("unchecked")
    @Override
    protected void publishResults(CharSequence constraint, FilterResults results) {
        filtered_items = (List<Word>) results.values;
        notifyDataSetChanged();
    }

}

}
