android - RecyclerView 在底部加载更多进度条

Question

我尝试实现 addOnScrollListener() 但这个东西每次都从头开始获取数据并加载回收器 View 。我想在当前位置之后加载数据。这是我的示例代码

 @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_load, null);

        progressBar = (ProgressBar) view.findViewById(R.id.progressBar);
        progressBar.setVisibility(View.VISIBLE);

        myClickHandler();

        business_rv = (RecyclerView) view.findViewById(R.id.business_rv);
        business = new LinearLayoutManager(getActivity(), LinearLayoutManager.VERTICAL,false);
        business_rv.setHasFixedSize(true);
        business_rv.setLayoutManager(business);
        if (business_rv.getLayoutManager() instanceof LinearLayoutManager) {
            business = (LinearLayoutManager) business_rv.getLayoutManager();
            business_rv.addOnScrollListener(new RecyclerView.OnScrollListener() {
                @Override
                public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
                    super.onScrolled(recyclerView, dx, dy);
                    UpdateRecyclerView(url);
                }
            });
        }

        return view;
    }

你需要的是无尽的回收 View ，它会在滚动时加载数据。在这里，我附上了该实现的链接。
