How to properly DEselect an item on RecyclerView?

I followed this answer:
https://stackoverflow.com/a/30046476/8793443
and got it to work: only one item is selected at a time (which is what I want).
However, when the same item is clicked for a second time, it remains selected. How can I deselect it so that it goes back to it's original color background?
Any help is appreciated.
Thanks!

Have you tried using isSelected()?

Yes. Unfortunately, I haven't figured out how to make it work given the way it's done on the example from my link. That is,notifyItemChanged(selectedPos)is used twice (once with the previous position and then with the current position). However, when the same item is selected,onBindViewHolderonly gets called once. How do you suggest usingisSelected()?

The OnClick event must be this instead:
@Override
public void onClick(View view) {
if (selectedPos == getAdapterPosition()) {
selectedPos = RecyclerView.NO_POSITION;
notifyDataSetChanged();
return;
}
selectedPos = getAdapterPosition();
notifyDataSetChanged();
}
It works like a charm! Thanks to Quick learner's answer for inspiration.
