android kotlin категории подкатегорий

Question

Я работал над проектом, который включает в себя категории и подкатегории. Проблема, которая у меня возникла, состоит в том, что, как только я нажимаю на категорию из списка, я получаю список подкатегорий, но я не могу найти способ получить указанный c идентификатор подкатегории. Каждый раз, когда я нажимаю на подкатегорию, в logcat я получаю O. Могу ли я попросить вас помочь мне с этим.
