如何在Recylcerview中刷新项目位置进行过滤？

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> implements Filterable {
    private List<String> mData;
    private List<String> mFilteredData;
    private MyFilter mFilter;

    public MyAdapter(List<String> data) {
        mData = data;
        mFilteredData = data;
        mFilter = new MyFilter();
    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        // 创建ViewHolder
    }

    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        // 绑定数据到ViewHolder
    }

    @Override
    public int getItemCount() {
        return mFilteredData.size();
    }

    @Override
    public Filter getFilter() {
        return mFilter;
    }

    public static class ViewHolder extends RecyclerView.ViewHolder {
        // ViewHolder的定义
    }

    private class MyFilter extends Filter {
        @Override
        protected FilterResults performFiltering(CharSequence constraint) {
            FilterResults results = new FilterResults();
            List<String> filteredList = new ArrayList<>();

            // 根据过滤条件对数据源进行过滤
            for (String item : mData) {
                if (item.contains(constraint)) {
                    filteredList.add(item);
                }
            }

            results.values = filteredList;
            results.count = filteredList.size();
            return results;
        }

        @Override
        protected void publishResults(CharSequence constraint, FilterResults results) {
            mFilteredData = (List<String>) results.values;
            notifyDataSetChanged();
        }
    }
}

public class MainActivity extends AppCompatActivity {
    private RecyclerView mRecyclerView;
    private MyAdapter mAdapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mRecyclerView = findViewById(R.id.recyclerView);
        // 初始化RecyclerView的布局管理器、适配器等

        List<String> data = new ArrayList<>();
        // 添加数据到data

        mAdapter = new MyAdapter(data);
        mRecyclerView.setAdapter(mAdapter);
    }

    private void filterData(String keyword) {
        mAdapter.getFilter().filter(keyword);
    }
}
