如何在RecyclerView为空的情况下使SwipeRefreshLayout工作

<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" />

</androidx.swiperefreshlayout.widget.SwipeRefreshLayout>

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

swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
    @Override
    public void onRefresh() {
        // 执行下拉刷新操作
        // 这里可以发送网络请求或者加载新数据
        // 刷新完成后记得调用 swipeRefreshLayout.setRefreshing(false) 结束刷新状态
    }
});

// 在合适的地方判断RecyclerView是否为空
if (adapter.getItemCount() == 0) {
    // RecyclerView为空时的处理逻辑
    // 可以显示空布局或者提示信息
    // 例如：emptyView.setVisibility(View.VISIBLE);
} else {
    // RecyclerView不为空时的处理逻辑
    // 例如：emptyView.setVisibility(View.GONE);
}
