Question

嗨，当recyclerview首次创建OnbindViewHolder直到recyclerview中的最后一个项目被调用时，我滚动时遇到了一个奇怪的问题 OnbindViewHolder未调用我需要解决此问题，因为我需要使用分页，但是在使用它时，它从第一次调用了所有页面这是OnbindViewHolder函数

@Override
    public void onBindViewHolder(@NonNull EnglishNewsViewHolder holder, int position) {
        Log.d("bbb", holder.getAdapterPosition() + "");
        if ((((getItemCount()) - 1) - holder.getLayoutPosition() < 5) && !noMoreDate) {

            loadMoreDate();
        }

这就是我将项目添加到适配器

的方式

 public void add(NewsModel model, int i) {
        dataList.add(model);
        notifyItemInserted(i);
    }

这是立即创建视图而不滚动的日志。

Answer 1

最后，我发现我必须实现nestedScrollListener的解决方案，因为recyclerview的滚动行为在NestedScrollView内部

Android：滚动时不会调用OnbindViewHolder
