如何使包含卷帘刷新布局的视图可滚动？

// 布局文件（activity_main.xml）
<androidx.swiperefreshlayout.widget.SwipeRefreshLayout
    android:id="@+id/swipeRefreshLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/recyclerView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scrollbars="vertical" />

</androidx.swiperefreshlayout.widget.SwipeRefreshLayout>

// 代码（MainActivity.java）
public class MainActivity extends AppCompatActivity implements SwipeRefreshLayout.OnRefreshListener {
    private SwipeRefreshLayout swipeRefreshLayout;
    private RecyclerView recyclerView;
    private MyAdapter adapter;

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

        swipeRefreshLayout = findViewById(R.id.swipeRefreshLayout);
        recyclerView = findViewById(R.id.recyclerView);

        swipeRefreshLayout.setOnRefreshListener(this);

        // 设置RecyclerView的布局管理器和适配器
        recyclerView.setLayoutManager(new LinearLayoutManager(this));
        adapter = new MyAdapter();
        recyclerView.setAdapter(adapter);
    }

    @Override
    public void onRefresh() {
        // 执行刷新数据的操作
        // ...

        // 更新RecyclerView的内容
        adapter.notifyDataSetChanged();

        // 停止刷新动画
        swipeRefreshLayout.setRefreshing(false);
    }
}
