Android: OnbindViewHolder doesn't call when i scroll

Question

Hi i am facing a strange problem when the recyclerview create first time OnbindViewHolder called until last item in recyclerview then when i scroll OnbindViewHolder not Called i need to solve this problem because i need to use pagination but when use it it called all pages from the first time this is OnbindViewHolder function

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

            loadMoreDate();
        }

and this is how i add the items to the adapter

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

and this is the Log after creating view immediately without scrolling.

Answer 1

If you use RecyclerView in RecyclerView, see also recyclerView does not call the onBindViewHolder when scroll in the view.

You should bind ViewHolder in onViewAttachedToWindow instead of onBindViewHolder like this:

// Remove onBindViewHolder because it is often not called
//override fun onBindViewHolder(holder: SomeViewHolder, position: Int) {
//    super.onBindViewHolder(holder, position)
//}

override fun onViewAttachedToWindow(holder: SomeViewHolder) {
    super.onViewAttachedToWindow(holder)

    val position = holder.adapterPosition
    val item = items[position]
    // Refresh inner list or bind ViewHolder.
}
