Get the ID and text of the RadioButton and manipulate the Data

Good morning, someone could help me with this question, how would I get the text and position of the radioButton put in an Arraylist and in my MainActivity that manages this RecyclerView to access this data.

Follow my Adapter

public class ExpandableRecyclerAdapter extends RecyclerView.Adapter<ExpandableRecyclerAdapter.ViewHolder> {
    private List<Repo> repos;

    private static final int TYPE_HEADER = 0;
    private static final int TYPE_ITEM = 1;

    public ExpandableRecyclerAdapter(List<Repo> repos) {
        this.repos = repos;
        for (int i = 0; i < repos.size(); i++) {
            expandState.append(i, false);
        }
    }

    @NonNull
    @Override
    public ExpandableRecyclerAdapter.ViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
        this.context = viewGroup.getContext();
        if (i == TYPE_HEADER) {
            View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.header_layout, viewGroup, false);
            return new HeaderVh(view);
        } else if (i == TYPE_ITEM) {

        }
        throw new RuntimeException("No macth for" + i + ".");
