Android CountDown Timer in Quiz Application

I have made a quiz application which include 5 questions. I have made a ResultActivity page which displays result of the quiz. I have added a countDown timer of 20 sec for each question. When the Countdown timer finishes it moves to the next question automatically. When the questions are finished it should move to the ResultActivity page to display result.

I have only one issue... Afetr reaching my last Question..if i does not select any answer and timer is finished the applicaton is not moving to my ResultActivity page..The timer is getting started again and again on the same question until i select any option

Here is my code:

QuizActivity.java

package com.example.triviality;
import java.util.LinkedHashMap;
import java.util.List;
import android.os.Bundle;
import android.os.CountDownTimer;

This is because Your return false statement will never be reached if the user has made no choice:

    if (rda.isChecked() || rdb.isChecked() || rdc.isChecked()){}

in this if else statement You will return false later. But if none is selected, You automatically will return true because the code block inside this statement above will not be rached. And then in Your timer You say:

    if (getNextQuestion(false)) {
            // Start The timer again
            countDownTimer.start();
        }

getNextQuestion is allways true if the user makes no choice, so the timer starts again and again.
