List of questions, each question with a list of answers

In fact use a scrollable view within another scrollable view behind problems.
Maybe that's why Android provides the ExpandableListView component that more is not what a ListView whose items are lists. So one solution to your problem would be to use one.

Define two classes, one to represent the question and another to represent the answer:

Question.java
Responsible for saving the question text, the answers, the correct answer and the selected answer.

public class Question {

    private final String questionText;
    private ArrayList<Answer> answers;
    private int selectedAnswer = -1;
    private int correctAnswer = -1;

    public Question(String text) {
        this.questionText = text;
        answers = new ArrayList<>();
    }

    public boolean isCorrectlyAnswered(){
        return correctAnswer == getSelectedAnswer();
    }

    public int getSelectedAnswer() {
        return selectedAnswer;
    }

    public void setSelectedAnswer(int selectedAnswer) {
        this.selectedAnswer = selectedAnswer;
    }


    public void setCorrectAnswer(int correctAnswer) {
        if(answers.size() <= correctAnswer){
            throw new IllegalArgumentException();
        }
        this.correctAnswer = correctAnswer;
    }

    public void addAnswer(String text){
        answers.add(new Answer(text));
    }

    public String getText(){
        return questionText;
    }

    public ArrayList<Answer> getAnswers(){
        return answers;
    }
}

Answer.java
Responsible for saving the text of the response.

public class Answer {

    private final String answerText;

    public Answer(String text){
        this.answerText = text;
    }

    public String getText() {
        return answerText;
    }

}  

The way to handle an ExpandableListView is similar to that of a ListView . The difference is that in addition to an Adpater and a view for items ( group ) it is necessary to define a view for the sub-items ( children ).

question_row.xml View for the questions, represents each of the ExpandableListView groups. Contains the question text and a sign to indicate if the question was answered correctly.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.v7.widget.CardView
        xmlns:card_view="http://schemas.android.com/apk/res-auto"
        android:id="@+id/card_view"
        android:layout_gravity="center"
        android:layout_width="match_parent"
        android:layout_height="75dp"
        card_view:cardCornerRadius="4dp">

        <TextView
            android:id="@+id/questionText"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:text="questionText"/>
        <CheckBox
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/correctMark"
            android:layout_gravity="right"
            android:clickable="false"
            android:focusable="false"
            android:checked="true"
            android:visibility="gone"/>
    </android.support.v7.widget.CardView>

</LinearLayout>

answer_row.xml View for responses, represents each of the sub items within each ExpandableListView group. Contains a RadioButton with the response text.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingLeft="16dp">

    <RadioButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="New RadioButton"
        android:id="@+id/answerText"
        android:clickable="false"
        android:focusable="false"/>
</LinearLayout>

ExpandListAdapter.java
Responsible for bridging the data and the ExpandableListView

public class ExpandListAdapter extends BaseExpandableListAdapter {

    private final LayoutInflater inflater;;
    private ArrayList<Question> questions;

    public ExpandListAdapter(Context context, ArrayList<Question> questions){
        inflater = LayoutInflater.from(context);
        this.questions = questions;
    }

    @Override
    public int getGroupCount() {
        return questions.size();
    }

    @Override
    public int getChildrenCount(int groupPosition) {
        ArrayList<Answer> answers = questions.get(groupPosition).getAnswers();
        if(answers == null){
            return 0;
        }
        return questions.get(groupPosition).getAnswers().size();
    }

    @Override
    public Object getGroup(int groupPosition) {
        return questions.get(groupPosition);
    }

    @Override
    public Object getChild(int groupPosition, int childPosition) {
        return questions.get(groupPosition).getAnswers().get(childPosition);
    }

    @Override
    public long getGroupId(int groupPosition) {
        return groupPosition;
    }

    @Override
    public long getChildId(int groupPosition, int childPosition) {
        return childPosition;
    }

    @Override
    public boolean hasStableIds() {
        return false;
    }

    @Override
    public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) {

        View row = convertView;
        ViewHolder holder;

        if (row == null)
        {
            row = inflater.inflate(R.layout.question_row, parent, false);
            holder = new ViewHolder();
            holder.addView(row.findViewById(R.id.questionText))
                  .addView(row.findViewById(R.id.correctMark));
            row.setTag(holder);
        }else{
            holder = (ViewHolder) row.getTag();
        }

        TextView questionText = (TextView) holder.getView(R.id.questionText);
        CheckBox correctMark = (CheckBox) holder.getView(R.id.correctMark);
        Question question = questions.get(groupPosition);

        if(question.isCorrectlyAnswered()) {
            correctMark.setVisibility(View.VISIBLE);
        }else {
            correctMark.setVisibility(View.GONE);
        }

        questionText.setText(question.getText());
        return row;

    }

    @Override
    public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {

        View row = convertView;
        ViewHolder holder;

        if (row == null)
        {
            row = inflater.inflate(R.layout.answer_row, parent, false);
            holder = new ViewHolder();
            holder.addView(row.findViewById(R.id.answerText));
            row.setTag(holder);
        }else{
            holder = (ViewHolder) row.getTag();
        }

        RadioButton answerText = (RadioButton) holder.getView(R.id.answerText);

        if(questions.get(groupPosition).getSelectedAnswer() == childPosition){
            answerText.setChecked(true);
        }else{
            answerText.setChecked(false);
        }
        answerText.setText(questions.get(groupPosition).getAnswers().get(childPosition).getText());

        return row;
    }

    @Override
    public boolean isChildSelectable(int groupPosition, int childPosition) {
        return true;
    }

    static class ViewHolder
    {
        private HashMap<Integer, View> storedViews = new HashMap<Integer, View>();

        public ViewHolder addView(View view)
        {
            int id = view.getId();
            storedViews.put(id, view);
            return this;
        }

        public View getView(int id)
        {
            return storedViews.get(id);
        }
    }
}

Only Activity is missing to display the list of questions and answers.

Just adapt to your liking.

I've done something similar these days, hopefully I can help you. In my problem I add a number of textView's dynamically, this amount varies according to a size of an ArrayList. You can adapt to your problem. Follow the code

        for (int i = 0; i < u.getLanguage().size(); i++) {
            language.addView(createTextView(addLanguage.getContext(), u.getLanguage().get(i), i,new LanguagesFragment()));
        }

createTextView method:

 private TextView createTextView(Context context, String text, int tag, final android.support.v4.app.Fragment f) {
    Bundle b = new Bundle();
    b.putInt("Position",tag);
    f.setArguments(b);
    TextView t = new TextView(context);
    t.setText(text);
    t.setTag(tag);
    t.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            getActivity().getSupportFragmentManager().beginTransaction().replace(R.id.carreira_detail_container,f).addToBackStack(null).commit();
        }
    });
    return t;
}

Explaining: The main part that will work for you is the context that I am calling in the createTextView method, this context is used to reference where the textView I am creating will be added, in the example we have it will be added below addLanguage . Follow the xml:

 <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical"
            android:layout_marginLeft="30dp"
            android:id="@+id/containerEducation">
        <Button
            android:id="@+id/addEducation"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@android:color/white"
            android:text="@string/addEducation"
            android:textAllCaps="false"
            /></LinearLayout>

Note that in nonlinear layout I set the offset as vertical so only one element will appear per line in my case this element is the textView. The result is the list of languages that were added below the add language button, follow image:

Place a Linear Layout inside the cardView or any layout that suits your needs. Do not use a Recycler View inside the CardView because the card_questions are inside a recycler view ja.

Take care not to put two components that have Scroll one inside the other.
