如何从具有CheckBox的嵌套Recycler View中获取数据？

如何解决如何从具有CheckBox的嵌套Recycler View中获取数据？

实际上，此屏幕显示一组问题，任务是读取用户输入或选择的答案。 所以我的问题是，如何从ChooseAdapter到QuestionAdapter获取值，然后从QuestionAdapter到我的Activity获取所有值。 我的英语有点弱，对此感到抱歉。 并预先感谢。

主适配器： QuestionAdapter.java

public class QuestionsAdapter extends RecyclerView.Adapter<QuestionsAdapter.RecyclerViewHolder> {

private ArrayList<Question> mRecyclerViewItems;

private static final int MENU_ITEM_VIEW_TYPE = 0;
private static final String TAG = QuestionsAdapter.class.getSimpleName();
private static Context mContext;

private NetworkManager nm;


private boolean visibility = false;

private ChoiceAdapter adapter;

private ArrayList<QuestionsAnswer> questionsAnswers = new ArrayList<>();
ArrayList<ChoiceAnswer> choiceAnswers;

public QuestionsAdapter(Context context,ArrayList<Question> recyclerViewItems) {
    this.mContext = context;
    this.mRecyclerViewItems = recyclerViewItems;

}


@Override
public RecyclerViewHolder onCreateViewHolder(ViewGroup parent,int viewType) {

    //this view contains recycler view under recycler view
    View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_question,parent,false);
    RecyclerViewHolder recyclerViewHolder = new RecyclerViewHolder(v);
    return recyclerViewHolder;

}

@Override
public void onBindViewHolder(RecyclerViewHolder holder,int position) {
    int viewType = getItemViewType(position);

    switch (viewType) {
        case MENU_ITEM_VIEW_TYPE:
        default:
            final RecyclerViewHolder recyclerViewHolder = (RecyclerViewHolder) holder;
            Question data = (Question) mRecyclerViewItems.get(position);


            try {

                recyclerViewHolder.txtQuestion.setText(data.getQuestion());
                recyclerViewHolder.txtQuestionType.setText(data.getQuestionType());

                if (data.getQuestionType().equals("MULT")) {
                    recyclerViewHolder.mRecyclerChoice.setVisibility(View.VISIBLE);
                    recyclerViewHolder.edtQuestion.setVisibility(View.GONE);

                    if (data.getChoices().size() > 0) {

                        adapter = new ChoiceAdapter(mContext,data.getChoices(),position);
                        recyclerViewHolder.mRecyclerChoice.setAdapter(adapter);
                    }


                } else {
                    recyclerViewHolder.mRecyclerChoice.setVisibility(View.GONE);
                    recyclerViewHolder.edtQuestion.setVisibility(View.VISIBLE);
                }

                recyclerViewHolder.btnOk.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {

                        if (data.getQuestionType().equals("MULT")) {

                            Log.v(TAG,"array Data : " + adapter.getChoiceAnswer());
                        } else {
                            Log.v(TAG,"array Data : " + recyclerViewHolder.edtQuestion.getText().toString());
                        }


                    }
                });

            } catch (NullPointerException e) {
                e.printStackTrace();
            }


    }
}


@Override
public int getItemCount() {
    return mRecyclerViewItems.size();
}


class RecyclerViewHolder extends RecyclerView.ViewHolder {

    TextView txtQuestion,txtQuestionType;
    EditText edtQuestion;
    RecyclerView mRecyclerChoice;
    Button btnOk;

    private LinearLayoutManager linearLayoutManager;

    public RecyclerViewHolder(View view) {
        super(view);

        txtQuestion = view.findViewById(R.id.txt_question);
        edtQuestion = view.findViewById(R.id.edt_question);
        mRecyclerChoice = view.findViewById(R.id.recycler_choice);
        btnOk = view.findViewById(R.id.btn_ok);
        txtQuestionType = view.findViewById(R.id.txt_question_type);



        initRecyclerView();

        btnOk.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                if (txtQuestionType.getText().toString().equals("MULT")) {

                    Log.v(TAG,"array Data : " + adapter.getChoiceAnswer());
                } else {
                    Log.v(TAG,"array Data : " + edtQuestion.getText().toString());
                }
            }
        });


    }


    private void initRecyclerView() {

        //setting properties of recyclerView
        mRecyclerChoice.setHasFixedSize(true);
        mRecyclerChoice.setHasFixedSize(true);
        linearLayoutManager = new LinearLayoutManager(mContext);
        mRecyclerChoice.setLayoutManager(linearLayoutManager);
    }


}

public static void validation() {
    Toast.makeText(mContext,"testing",Toast.LENGTH_SHORT).show();
}}

对于CheckBox列表：ChooseAdapter.java

public class ChoiceAdapter extends RecyclerView.Adapter<ChoiceAdapter.RecyclerViewHolder> {

private ArrayList<Choice> mRecyclerViewItems;

private static final int MENU_ITEM_VIEW_TYPE = 0;
private static final String TAG = ChoiceAdapter.class.getSimpleName();
private Context mContext;

private NetworkManager nm;

// private OnItemClickListener mOnItemClickListener;

private boolean visibility = false;

private static ArrayList<ChoiceAnswer> choiceAnswerArrayList;
private ChoiceAnswer choiceAnswer;
String arrayData;

public ChoiceAdapter(Context context,ArrayList<Choice> recyclerViewItems,int position) {
    this.mContext = context;
    this.mRecyclerViewItems = recyclerViewItems;

    // choiceAnswer.key = 0;
    choiceAnswerArrayList = new ArrayList<>();


    //initializing choiceAnswer
    choiceAnswer = new ChoiceAnswer();
    choiceAnswer.values = new ArrayList<>();
}


@Override
public RecyclerViewHolder onCreateViewHolder(ViewGroup parent,int viewType) {

    //this view contains recycler view under recycler view
    View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_radio_button,int position) {
    int viewType = getItemViewType(position);

    switch (viewType) {
        case MENU_ITEM_VIEW_TYPE:
        default:
            final RecyclerViewHolder recyclerViewHolder = (RecyclerViewHolder) holder;
            Choice data = (Choice) mRecyclerViewItems.get(position);


            try {

                recyclerViewHolder.checkChoice.setText(data.getChoiceName());

                recyclerViewHolder.checkChoice.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
                    @Override
                    public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {

                        arrayData = "";
                        for (int i = 0; i < mRecyclerViewItems.size(); i++) {
                            if (isChecked) {
                                if (!choiceAnswer.values.contains(data.getChoiceID())) {
                                    choiceAnswer.values.add(i,data.getChoiceID());
                                }
                            } else {
                                choiceAnswer.values.remove(data.getChoiceID());
                                // arrayData = choiceAnswer.values.toString().replace("[","").replace("]","").trim();
                            }

                            try {

                                arrayData = arrayData + "," + choiceAnswer.values.get(i);
                            }catch (IndexOutOfBoundsException e){
                                e.printStackTrace();
                            }
                        }
                    }
                });

            } catch (NullPointerException e) {
                e.printStackTrace();
            }


    }
}

public String getChoiceAnswer() {
    return arrayData;
}

@Override
public int getItemCount() {
    return mRecyclerViewItems.size();
}


class RecyclerViewHolder extends RecyclerView.ViewHolder {

    CheckBox checkChoice;


    public RecyclerViewHolder(View view) {
        super(view);

        checkChoice = view.findViewById(R.id.check_choice);


    }
