Receiving RadioButton value in RecyclerView

Good evening.

I would like your help on a problem I'm having, I'm developing an app for a college job, in case I'm going to have an activity that will have some sort of research, or quiz, whatever you want to call it.

The question, and the answers are stored in the firebase, I set everything up on a screen, where the user can select the options for each question. Then there is my question, what I want and the next, the user should select all the answers, and at the end click the button, which will redirect to another activity that will show the result.

This is the problem, I am using a recyclerview to do the list of questions and answers, all in a single activity, how do I store user responses, then send the result to another activity?
