具有RadioGroup的RecyclerView不会保存状态

Question

下面的代码是一个recyclerview适配器，如果对radiogroup有疑问，则适配器不会保存单选按钮状态并且滚动太慢， 有什么建议吗？ onClick函数由活动实现，以存储使用选择并计算一些业务。

public class PersonalityTestAdapter extends RecyclerView.Adapter<PersonalityTestAdapter.ViewHolder> {

    private List<Question> questions = new ArrayList<>();
    private List<Integer> choises = new ArrayList<>();
    private final PersonalityTestAdapter.OnItemClickListner listner;
    private Context context;


    public interface OnItemClickListner{
        void onItemClick(int id,int checkedId);

    }

    @NonNull
    @Override
    public PersonalityTestAdapter.ViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
        View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.personality_test_question_item,viewGroup,false);
        return new PersonalityTestAdapter.ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(@NonNull PersonalityTestAdapter.ViewHolder viewHolder, int i) {

        viewHolder.bind(i,listner);

    }

    @Override
    public int getItemCount() {
        if(questions == null){
            return 0;
        }else{
            return questions.size();
        }
    }

    public PersonalityTestAdapter(OnItemClickListner listener){
        this.listner = listener;

    }

    public void setData(List<Question> questions, List<Integer> choises){

        this.questions = questions;
        this.choises = choises;
        notifyDataSetChanged();
    }

    class ViewHolder extends RecyclerView.ViewHolder{


        @BindView(R.id.personality_test_question_id)
        TextView mQuestionId;

        @BindView(R.id.personality_test_question)
        TextView mQuestion;

        @BindView(R.id.personality_test_radio_group)
        RadioGroup mRadioGroup;

        public ViewHolder(View itemView){
            super(itemView);
            ButterKnife.bind(this,itemView);


        }
        public void bind(final int id, final OnItemClickListner listner){
            Question question = questions.get(id);
            if(question != null){
                mQuestionId.setText(String.valueOf(question.getId()));
                itemView.
                Log.d("id", String.valueOf(question.getId()));
                mQuestion.setText(question.getQuestion());
                Integer checkedId = choises.get(id);
                if(checkedId == -1){
                    mRadioGroup.clearCheck();
                }else{
                    mRadioGroup.check(checkedId);
                }
            }


            mRadioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
                @Override
                public void onCheckedChanged(RadioGroup group, int checkedId) {
                    listner.onItemClick(id,checkedId);
                    choises.add(id,checkedId);
                }
            });
            //itemView.setOnClickListener(new View.OnClickListener() {
               // @Override
                //public void onClick(View v) {
                   //listner.onItemClick(id);
                    //Log.d("firdt"," this was clicked"+id);
                //}
            //});
        }

    }
}
