如何在RecyclerView中向下滚动时逐个加载JSON响应数组项？

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private List<DataModel> dataList = new ArrayList<>();
    private int currentPage = 0;
    private boolean isLoading = false;

    // ...

    @Override
    public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
        // 绑定数据到ViewHolder
        DataModel data = dataList.get(position);
        holder.bindData(data);

        // 当滚动到列表底部时，加载下一页数据
        if (position == dataList.size() - 1 && !isLoading) {
            loadNextPage();
        }
    }

    private void loadNextPage() {
        isLoading = true;
        currentPage++;

        // 发送HTTP请求获取JSON响应
        // 这里使用OkHttp作为示例
        OkHttpClient client = new OkHttpClient();
        Request request = new Request.Builder()
                .url("http://example.com/api/data?page=" + currentPage)
                .build();

        client.newCall(request).enqueue(new Callback() {
            @Override
            public void onResponse(Call call, Response response) throws IOException {
                if (response.isSuccessful()) {
                    String json = response.body().string();

                    // 解析JSON响应，将每个数组项转换为数据模型对象
                    List<DataModel> newDataList = parseJson(json);

                    // 将新数据添加到列表中
                    dataList.addAll(newDataList);

                    // 刷新RecyclerView的显示
                    notifyDataSetChanged();
                }
                isLoading = false;
            }

            @Override
            public void onFailure(Call call, IOException e) {
                isLoading = false;
                e.printStackTrace();
            }
        });
    }

    // ...
}
