I am trying to create messaging kind of screen using recyclerView which will start from bottom and will loadMore data when user reached top end of chat. But I am facing this weird issue.
My recyclerView scrolls to top on calling notifyDataSetChanged. Due to this onLoadMore gets called multiple times.
Here is my code:
LinearLayoutManager llm = new LinearLayoutManager(context);
llm.setOrientation(LinearLayoutManager.VERTICAL);
llm.setStackFromEnd(true);
recyclerView.setLayoutManager(llm);
** In Adapter
@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
if (messages.size() > 8 && position == 0 && null != mLoadMoreCallbacks) {
mLoadMoreCallbacks.onLoadMore();
}
** In Activity
@Override
public void onLoadMore() {
// Get data from database and add into arrayList
chatMessagesAdapter.notifyDataSetChanged();
}
It's just that recyclerView scrolls to top. If scrolling to top stops, this issue will be resolved. Please help me to figure out the cause of this issue. Thanks in advance.
