RecyclerView adapter taking wrong values

This usually happens when you have something like "if (field != null) holder.setField(field)", without an else. The holder is recycled, this means that it will have values there, so you need to clean or replace EVERY value, if it's null you should nullit, if it's not, you should write it, ALWAYS. It's late, but, as an answer for others.

for me setting setHasStableIds(false) solved the problem.
