RecyclerView适配器中的空监听程序

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private List<Data> dataList;
    private View emptyView;

    // 构造方法
    public MyAdapter(List<Data> dataList, View emptyView) {
        this.dataList = dataList;
        this.emptyView = emptyView;
    }

    // 判断数据是否为空
    public boolean isEmpty() {
        return dataList.isEmpty();
    }

    // 设置空监听程序
    public void setEmptyListener() {
        if (isEmpty()) {
            emptyView.setVisibility(View.VISIBLE);
        } else {
            emptyView.setVisibility(View.GONE);
        }
    }

    // 其他方法...

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

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

    // ViewHolder类...

}

// 初始化RecyclerView
RecyclerView recyclerView = findViewById(R.id.recyclerView);
View emptyView = findViewById(R.id.emptyView);

// 创建适配器
MyAdapter adapter = new MyAdapter(dataList, emptyView);

// 设置空监听程序
adapter.setEmptyListener();

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