RecyclerView and get ItemId

Question

I am implementing a swipe to delete with a RecyclerView and an ItemTouchHelper. Within my onSwiped function, I call my service to delete the element with an API request, but for that I need the adapter to give me the id of the element. I overrided the getItemId() function of my Adapter

@Override
public long getItemId(int position) {
   return dataSet.get(position).getId();
}

However when I am using it in my onSwiped function

@Override
public void onSwiped(RecyclerView.ViewHolder viewHolder, int swipeDir) {
     AddBaseService addBaseService = AddBaseService.sharedInstance();
     long baseId = viewHolder.getItemId(viewHolder.getAdapterPosition());
     addBaseService.deleteBase(String.valueOf(baseId));

I got an error at the getAdapterPosition line saying

getItemId() in ViewHolder cannot be applied to (int)

although getAdapterPosition is supposed to return an int :/

EDIT:

Here are two links that might help you solve your issue :

• What is the intent of the methods getItem and getItemId in the Android class BaseAdapter?
• how to get ID of the items in recyclerview

OP used : adapter.getItemId(viewHolder.getAdapterPosition()); instead of viewHolder.getItemId() to solve his problem.
