@Override public void onBindViewHolder(@NonNull final ViewHolder holder, final int position) { ModelGetAddress adapterAddress = modelGetAddressList.get(position);

    convertAddressID = String.valueOf(adapterAddress.getId());
}

public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
    private RadioButton radioButton;

    public ViewHolder(@NonNull View itemView) {
        super(itemView);

        radioButton = itemView.findViewById(R.id.radioButton);
        itemView.setOnClickListener(this);


    }

    @Override
    public void onClick(View view) {
        int position=getAdapterPosition();
        Toast.makeText(conext, ""+modelGetAddressList.get(position).getId(), Toast.LENGTH_SHORT).show();

    }
}
