Here is an example of how to create radiogroup, radiobutton and how to use in Java code. Hope it will give you complete picture

public void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    RadioGroup rgrpMapType = (RadioGroup) findViewById(R.id.maptype);
    int selectedTypeId = rgrpMapType.getCheckedRadioButtonId();
    RadioButton rbMapType = (RadioButton) findViewById(selectedTypeId);
    if(rbMapType != null) // This will be null if none of the radio buttons are selected
           rgrpMapType.clearCheck();

Prefrences are defined at the activity level. I'll have my bounty please.

Call getActivity() to get the callers activity then use that to get the prefrences. If you want structure send results back via interface. Implement the interface and use the interface to find the activity. Eclipse creates stubs for you.

Here is the complete class that just changes a prefrence save's it and immediately sends the result back to the calling class. It uses getActivity() so the two classes share the same prefrences. It calls back through an interface.

It's from my app com.gosylvester.bestrides

Put the settings in a diaglog fragment activated from button in the actionbar have an interface so you can update the map in background.

See this live in my app

Button in action bar.

<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:yourapp="http://schemas.android.com/apk/res-auto" >

<item
    android:id="@+id/action_settings"
    android:icon="@drawable/action_settings"
    android:orderInCategory="100"
    android:title="@string/action_settings"
    android:showAsAction="always"
    yourapp:showAsAction="always"/>

Process the button click

@Override
public boolean onOptionsItemSelected(MenuItem item) {

    int x = item.getItemId();
    switch (x) {
    case R.id.action_settings:
        showSettingsDialog();
         return true;

do something useful show the fragment.

private void showSettingsDialog() {
    FragmentManager fm = getSupportFragmentManager();
    MapSettings editSettingsDialog = new MapSettings();
    editSettingsDialog.show(fm, "fragment_edit_name");
}

The complete mapsettings class.

public class MapSettings extends DialogFragment implements
    OnCheckedChangeListener {

    public static final String MAP_TYPE = "com.gosylvester.bestrides.settings.maptype";
BestRidesSettingsDialogListener activity;
SharedPreferences sharedpref;

public interface BestRidesSettingsDialogListener {
    void onMapSettingsChange(int mapType);
}

@Override
public void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
}

    @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
         Bundle savedInstanceState) {

    // the activity may be null if this is called without implementing the
     // BestRidesSettingsDialogListener (The settings object saves the
    // setting so the
    // call back may not be needed.

     activity = (BestRidesSettingsDialogListener) getActivity();

     getDialog().setTitle(R.string.app_name);
    View view = inflater.inflate(R.layout.activity_map_settings, container);
    RadioGroup rg = (RadioGroup) view.findViewById(R.id.radioGroup1);
    // initialize to the shared preferences value
    rg.clearCheck();

 ... homemade glue to get the initial setting.      
GoPreferences.getInt(getActivity(),MAP_TYPE,GoogleMap.MAP_TYPE_NORMAL);

    RadioButton rb = null;

     switch (x) {
    case GoogleMap.MAP_TYPE_HYBRID:
         rb = (RadioButton) view.findViewById(R.id.RDOHybrid);
        rb.setChecked(true);
        break;
    case GoogleMap.MAP_TYPE_NORMAL:
        rb = (RadioButton) view.findViewById(R.id.RDORoad);

    case GoogleMap.MAP_TYPE_SATELLITE:
        rb = (RadioButton) view.findViewById(R.id.RDOSatelite);
        rb.setChecked(true);
        break;
    case GoogleMap.MAP_TYPE_TERRAIN:
        rb = (RadioButton) view.findViewById(R.id.RDOTerrain);
        rb.setChecked(true);
        break;
    }
    // set the listener after setting up
    rg.setOnCheckedChangeListener(this);
    return view;
}   

@Override
public void onCheckedChanged(RadioGroup rg, int checkId) {
    // TODO Auto-generated method stub
    int mapType = 0;
    switch (checkId) {
    case R.id.RDORoad:
        mapType = GoogleMap.MAP_TYPE_NORMAL;
        break;
    case R.id.RDOHybrid:
        mapType = GoogleMap.MAP_TYPE_HYBRID;
        break;
    case R.id.RDOSatelite:
        mapType = GoogleMap.MAP_TYPE_SATELLITE;
        break;
    case R.id.RDOTerrain:
        mapType = GoogleMap.MAP_TYPE_TERRAIN;
        break;
    }
    // run the activity onchange
    // if the activity is null there is no listener to take action on the
    // settings
    if (activity != null) {
        activity.onMapSettingsChange(mapType);
    }

    // save the settings


}

impliment the interface on your map activity so the map can be changed from the dialog fragment.

public class KmlReader extends ActionBarActivity implements
    BestRidesSettingsDialogListener, SnapshotReadyCallback,
    OnMapLoadedCallback {



@Override
public void onMapSettingsChange(int mapType) {
    // TODO Auto-generated method stub
    if (mMap != null) {
        mMap.setMapType(mapType);
    }
}

I suggest creating a new class called QuestionAndAnswer. The class should hold the question and the correct answer, it could also hold any customized wrong answers and the user's choice. The exact implementation is entirely up to you.

In your Activity have an Array of this QuestionAndAnswer class to cycle through the list asking the questions and tally up the points when done.

(I could be more specific if you include the relevant code of what you have tried.)

Addition

This is what I would start with:
(From your code I'm guessing the distractorList contains the false answers that you want to display.)

public class QuestionAndAnswer {
    public List<String> allAnswers; // distractors plus real answer
    public String answer;
    public String question;
    public String selectedAnswer;
    public int selectedId = -1;

    public QuestionAndAnswer(String question, String answer, List<String> distractors) {
        this.question = question;
        this.answer = answer;
        allAnswers = new ArrayList<String> (distractors);

        // Add real answer to false answers and shuffle them around 
        allAnswers.add(answer);
        Collections.shuffle(allAnswers);
    }

    public boolean isCorrect() {
        return answer.equals(selectedAnswer);
    }
}

For the Activity I changed your four answer TextViews into a RadioGroup, this way the user can intuitively select an answer. I also assume that there will be prev and next buttons, they will adjust int currentQuestion and call fillInQuestion().

public class Example extends Activity {
    RadioGroup answerRadioGroup;
    int currentQuestion = 0;
    TextView questionTextView;
    List<QuestionAndAnswer> quiz = new ArrayList<QuestionAndAnswer>();

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        questionTextView = (TextView) findViewById(R.id.question);
        answerRadioGroup = (RadioGroup) findViewById(R.id.answers);

        // Setup a listener to save chosen answer
        answerRadioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(RadioGroup group, int checkedId) {
                if(checkedId > -1) {
                    QuestionAndAnswer qna = quiz.get(currentQuestion);
                    qna.selectedAnswer = ((RadioButton) group.findViewById(checkedId)).getText().toString();
                    qna.selectedId = checkedId;
                }
            }
        });

        String[] question = { //questions here// };  
        String[] answer = { //answers here// };  
        String[] distractor = { //distractors here// };  
        ArrayList<String> distractorList = Arrays.asList(distractor);  

        /* I assumed that there are 3 distractors per question and that they are organized in distractorList like so:
         *   "q1 distractor 1", "q1 distractor 2", "q1 distractor 3", 
         *   "q2 distractor 1", "q2 distractor 2", "q2 distractor 3",
         *   etc
         *   
         * If the question is: "The color of the sky", you'd see distractors:
         *   "red", "green", "violet"
         */   
        int length = question.length;
        for(int i = 0; i < length; i++)
            quiz.add(new QuestionAndAnswer(question[i], answer[i], distractorList.subList(i * 3, (i + 1) * 3)));
        Collections.shuffle(quiz);

        fillInQuestion();
    }

    public void fillInQuestion() {
        QuestionAndAnswer qna = quiz.get(currentQuestion);
        questionTextView.setText(qna.question);

        // Set all of the answers in the RadioButtons 
        int count = answerRadioGroup.getChildCount();
        for(int i = 0; i < count; i++)
            ((RadioButton) answerRadioGroup.getChildAt(i)).setText(qna.allAnswers.get(i));

        // Restore selected answer if exists otherwise clear previous question's choice
        if(qna.selectedId > -1)
            answerRadioGroup.check(qna.selectedId);
        else 
            answerRadioGroup.clearCheck();
    }
}

You may have noticed that QuestionAndAnswer has an isCorrect() method, when it is time to grade the quiz you can count the correct answers like this:

int correct = 0;
for(QuestionAndAnswer question : quiz)
    if(question.isCorrect())
        correct++;

This is my general idea. The code is a complete thought, so it will compile. Of course, you'll want to add a "next" Button to see the different questions. But this is enough for you to see one way to randomize your questions and answers while keeping them organized.
