无法使用ListView为ArrayAdapter中的单选按钮设置ID

Question

[示例项目download link]

我正在使用一个教程测验应用程序。我有一些问题，每个问题都有三个答案，即单选组中的3个单选按钮。问题是，当我对单选按钮使用setId时，我得到了替换的答案，所以问题1得到了问题5的答案，依此类推，这一切都错了。当我没有为单选按钮设置setId时，我会为每个问题正确放置答案，但是现在的问题是，当我提交问题的答案时，它也会引起另一个问题，因为单选按钮在收听提交按钮时没有id可以捕捉点击。

我尝试再次设置setId，但相同的问题是替换问题之间的答案。如何为每个单选按钮指定不同的ID？我尝试制作randon编号，但是向下滚动时，第一个隐藏的问题重复了该编号。

public class QuestionsAdapter extends ArrayAdapter<Questions> {

public QuestionsAdapter(Activity context, ArrayList<Questions> questions) {
    super(context, 0, questions);
}

private int t;
Random ran = new Random();
// Assumes max and min are non-negative.

@NonNull
@Override
public View getView(int position, View convertView, ViewGroup parent) {

    View listItemView = convertView;
    if (listItemView == null) {
        listItemView = LayoutInflater.from(getContext()).inflate(R.layout.list_item, parent, false);
    }
        //styling odd and even items
        if (position % 2 == 1) {
            listItemView.setBackgroundColor(getContext().getResources().getColor(R.color.odd));
        } else {
            listItemView.setBackgroundColor(getContext().getResources().getColor(R.color.even));
        }

        //used ViewHolder to prevent triggering position null issue
        final ViewHolder viewHolder = new ViewHolder();

        try {
            final Questions currentQuestion = getItem(position);

            String question = currentQuestion.getQuestionTitle();
            String option_1 = currentQuestion.getQuestionAnswer1();
            String option_2 = currentQuestion.getQuestionAnswer2();
            String option_3 = currentQuestion.getQuestionAnswer3();
            int q_id = currentQuestion.getQID();

            viewHolder.questionTextView = (TextView) listItemView.findViewById(R.id.q_text);
            viewHolder.questionTextView.setText(question);

            viewHolder.radioGroup = (RadioGroup) listItemView.findViewById(R.id.q_answers);

            viewHolder.firstAnswer = (RadioButton) listItemView.findViewById(R.id.q_option1);
            viewHolder.firstAnswer.setText(option_1);

            viewHolder.secondAnswer = (RadioButton) listItemView.findViewById(R.id.q_option2);
            viewHolder.secondAnswer.setText(option_2);

            viewHolder.thirdAnswer = (RadioButton) listItemView.findViewById(R.id.q_option3);
            viewHolder.thirdAnswer.setText(option_3);

            final TextView resultTextView = (TextView) listItemView.findViewById(R.id.result_text);

            final Button viewAnswer = (Button) listItemView.findViewById(R.id.view_answer_btn);
            viewAnswer.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    if(viewHolder.radioGroup.getCheckedRadioButtonId()!=-1){

                        //getting checked radio button and save it's text in a string
                        int selectedAnswerId = viewHolder.radioGroup.getCheckedRadioButtonId();
                        View radioButton = viewHolder.radioGroup.findViewById(selectedAnswerId);
                        int radioId = viewHolder.radioGroup.indexOfChild(radioButton);
                        RadioButton btn = (RadioButton) viewHolder.radioGroup.getChildAt(radioId);
                        String selection = (String) btn.getText();

                        //displaying the empty result TextView
                        resultTextView.setVisibility(View.VISIBLE);

                        //if answer is correct (selection equals the answer in the array
                        if( selection == currentQuestion.getCorrect() ){

                            //increasing score by 1
                            MainActivity.score += 1;

                            //displaying the score
                            MainActivity.scoreTextView.setText(getContext().getResources().getString(R.string.score_is) +
                                    MainActivity.score + "/" + MainActivity.arraySize);
