Доброго времени суток. Есть адаптер, внутри него кончено же есть onBindViewHolder, там есть условие, при котором должна запускаться одна функцию, которая вообще по идеи находится в MainActivity)
Буду признателен за помощь, так как новичок в Java и не понимаю толком как подобное реализовать.
Вот и адаптер:

Простой
