Recyclerview notifyDataSetChanged两次停止分页

Question

我有一个片段，其中包含需要分页的recyclerview 因此一旦到达末尾，它将调用API来检索新数据并追加到列表中。

此外，我刚刚在视图中添加了swipeRefreshLayout，一旦用户滑动刷新，它将清除recyclerview并再次添加数据

现在的问题是，一旦调用要刷新的刷卡，适配器将无法检测到recyclerview的结束

下面的代码：

 newsSwipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
        @Override
        public void onRefresh() {
            generateNews(1);
        }
    });

    adapterNews.setLoadMore(new ToLoadMore() {
        @Override
        public void LoadMore() {
            if (next_offset != 0) {

                newsList.add(null);

                adapterNews.notifyItemInserted(newsList.size() - 1);

                newsApi.GetNews(Constant.ACCESSTOKEN, next_offset).enqueue(new Callback<NewsData>() {
                    @Override
                    public void onResponse(Call<NewsData> call, Response<NewsData> response) {
                        Log.d("PAGINATION", "PAGINATION");
                        newsList.remove(newsList.size() - 1);
                        adapterNews.notifyItemRemoved(newsList.size());

                        newsList.addAll(response.body().getNews());
                        next_offset = response.body().getNextOffset();

                        adapterNews.notifyDataSetChanged();
                        adapterNews.setLoaded();
                    }

                    @Override
                    public void onFailure(Call<NewsData> call, Throwable t) {

                    }
                });
            }
        }
    });

    generateNews(1);


    return v;
}

产生新闻的功能如下

private void generateNews(final int offset) {
    newsApi.GetNews(Constant.ACCESSTOKEN, offset).enqueue(new Callback<NewsData>() {
        @Override
        public void onResponse(Call<NewsData> call, Response<NewsData> response) {
            newsList.clear();
            newsList.addAll(response.body().getNews());
            next_offset = response.body().getNextOffset();

            if (newsSwipeRefreshLayout.isRefreshing()) {
                newsSwipeRefreshLayout.setRefreshing(false);
            }

            news_progressbar.setVisibility(View.GONE);
            news_progressText.setVisibility(View.GONE);
            newsRecyclerView.setVisibility(View.VISIBLE);

            adapterNews.notifyDataSetChanged();

        }

        @Override
        public void onFailure(Call<NewsData> call, Throwable t) {

            snackbar = Snackbar.make(getView(), "No Internet Connection", Snackbar.LENGTH_INDEFINITE).setAction("Close", new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    snackbar.dismiss();
                    generateNews(1);
                }
            });
            snackbar.show();

            if (newsSwipeRefreshLayout.isRefreshing()) {
                newsSwipeRefreshLayout.setRefreshing(false);
            }


        }
    });
}
