android notifyItemRangeInserted disable autoscroll

Question

I'm using RecyclerView as the base for my data list. i've implemented custom RecyclerView.Adapter which is based on ArraList. on fetching data from the internet the code that i'm running is:

public void addItems(List<Item> items){

    final int size = data.size();
    data.addAll(items);
    notifyItemRangeInserted(size, items.size());
}

Problem is that for after running this code i'm getting an autoscroll to the bottom of the list (last element is now visible)

Is there a way to disable this? couldn't find any similar questions.

relevant information: my adapter have 2 viewHolders - for position 0 it has a view (with viewType 0) and for the rest of list it has view with viewType 1

Thanks for your help!

Problem is in your positionStart. Should be:

public void addItems(List<QuestItem> items){    
    final int positionStart = data.size() + 1;
    data.addAll(items);
    notifyItemRangeInserted(positionStart, items.size());
}
