RecyclerView ItemTouchHelper滑动操作在片段类中不起作用

public class MyFragment extends Fragment {

    private RecyclerView recyclerView;
    private MyAdapter adapter;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_my, container, false);

        recyclerView = view.findViewById(R.id.recyclerView);
        adapter = new MyAdapter();

        // 设置布局管理器
        recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));

        // 设置适配器
        recyclerView.setAdapter(adapter);

        // 创建ItemTouchHelper实例
        ItemTouchHelper itemTouchHelper = new ItemTouchHelper(new ItemTouchHelper.SimpleCallback(ItemTouchHelper.UP | ItemTouchHelper.DOWN, ItemTouchHelper.LEFT | ItemTouchHelper.RIGHT) {
            @Override
            public boolean onMove(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, RecyclerView.ViewHolder target) {
                // 处理拖拽排序逻辑
                return false;
            }

            @Override
            public void onSwiped(RecyclerView.ViewHolder viewHolder, int direction) {
                // 处理滑动删除逻辑
            }
        });

        // 将ItemTouchHelper附加到RecyclerView上
        itemTouchHelper.attachToRecyclerView(recyclerView);

        return view;
    }
}
