Select all checkboxes in RecyclerView

How can I select all checkboxes in recyclerView?

I try to do it like this:

in Adapter:

   public void selectAll

You made a simple mistake here

  if (!isSelectedAll) holder.select_item.setChecked(false);
    else holder.select_item.setChecked(true);

change setSelected into setChecked thats it
