android – RecyclerView滚动侦听器的方法onscolled自动调用而不滚动

在实施分页时.我遇到了这个问题.不滚动onscrolled方法不断调用.
请检查下面的代码.

作为参考,我使用的是Endless Scrolling with AdapterViews and RecyclerView

还有一个演示示例this.

我正在从API请求数据.所以我实施了凌空.安装完成后,发生了奇怪的事情OnScrolled方法连续调用而不滚动.
以下是我的代码.

    HomeFragment.java

    view = inflater.inflate(R.layout.fragment_home,container,false);

    tvNoDataFound = (TextView) view.findViewById(R.id.tv_no_data_found);
    recyclerView = (RecyclerView)view.findViewById(R.id.listView);

    linearLayoutManager = new LinearLayoutManager(getActivity());

    recyclerView.setNestedScrollingEnabled(false);

    recyclerView.setLayoutManager(linearLayoutManager);


    context = view.getContext();

    // Lookup the swipe container view
    swipeProjects = (SwipeRefreshLayout)view.findViewById(R.id.swipeProjects);

    // Setup refresh listener which triggers new data loading
    swipeProjects.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
        @Override
        public void onRefresh() {
            // Your code to refresh the list here.
            // Make sure you call swipeContainer.setRefreshing(false)
            // once the network request has completed successfully.
            getProjects(0,0);
        }
    });
    // Configure the refreshing colors
    swipeProjects.setColorSchemeResources(android.R.color.holo_blue_bright,android.R.color.holo_green_light,android.R.color.holo_orange_light,android.R.color.holo_red_light);

    List


从服务器获得响应后,我使用下面的函数来设置适配器.

public List

在上面的代码中,我的第一个API调用偏移0.我不知道是什么问题.是因为凌空异步请求吗？


最佳答案
是的,它会被调用.用这个克服一种方法

private boolean isLastItemDisplaying(RecyclerView recyclerView) {
    if (recyclerView.getAdapter().getItemCount() != 0) {
        int lastVisibleItemPosition = ((LinearLayoutManager) recyclerView.getLayoutManager()).findLastCompletelyVisibleItemPosition();
        if (lastVisibleItemPosition != RecyclerView.NO_POSITION && lastVisibleItemPosition == recyclerView.getAdapter().getItemCount() - 1)
            return true;
    }
    return false;
}

现在用onScolled方法检查该方法.

 boolean a = isLastItemDisplaying(recycler_product);
 if(a)
     {
        List
