我正在使用从Parse.com数据库加载数据的endless Recyclerview。我面临的问题是它显示了两个加载图像,如下面的屏幕所示。我想在时间显示一个项目然后在滚动时显示图标,然后加载下一个项目。

EndlessScroll的代码是 -

public abstract class EndlessScroll extends RecyclerView.OnScrollListener {
    public static String TAG = EndlessScroll.class.getSimpleName();

    private int previousTotal = 0; // The total number of items in the dataset after the last load
    private boolean loading = true; // True if we are still waiting for the last set of data to load.
    private int visibleThreshold = 2; // The minimum amount of items to have below your current scroll position before loading more.
    int firstVisibleItem, visibleItemCount, totalItemCount;

    Context context;    
    private int current_page = 1;    
    private LinearLayoutManager mLinearLayoutManager;

    public EndlessScroll(LinearLayoutManager linearLayoutManager, Context context) {
        this.mLinearLayoutManager = linearLayoutManager;
        this.context = context;
    }

    @Override
    public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
        super.onScrolled(recyclerView, dx, dy);  

        visibleItemCount = recyclerView.getChildCount();
        totalItemCount = mLinearLayoutManager.getItemCount();
        firstVisibleItem = mLinearLayoutManager.findFirstVisibleItemPosition();

        if (loading) {     
            if (totalItemCount > previousTotal) {
                loading = false;
                previousTotal = totalItemCount;
            }
        }
        if (!loading && (totalItemCount - visibleItemCount)
                <= (firstVisibleItem + visibleThreshold)) {    

            // End has been reached    
            // Do something
            current_page++;
            onLoadMore(current_page);    
            loading = true;
        }
    }    
    public abstract void onLoadMore(int current_page);
}

我已经开始在Android工作了。

我不确定为什么加载行为有问题。

非常感谢您的帮助/建议/任何指针。
