Estoy trabajando en Android Quiz y quiero un temporizador en cada página de preguntas y respuestas. Tengo una página de menú en mi botón de prueba y juego para comenzar el juego. Y quiero que este temporizador se active cuando hago clic en el botón de reproducción. Para esto tengo que crear TextView en la pregunta XML que representa mi página de menú. Y la implementación en la clase QuestionActivity que representa mi primera página de preguntas. También estoy publicando la clase WelcomeActivity, aunque no juega ningún papel en esta pregunta.

Disposición del botón de reproducción

<Button 
            android:text="Play" 
            android:id="@+id/playBtn"
            android:layout_width="80dip" 
            android:layout_alignParentRight="true"
            android:layout_height="wrap_content"
            android:paddingTop="5dip" 
            android:paddingBottom="5dip"
            android:textColor="#ffffff"
            android:background="@drawable/start_button" />

Pregunta XML que representa a TextView para el temporizador

<TextView
    android:id="@+id/textView1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_above="@+id/question"
    android:layout_centerHorizontal="true"
    android:background="@drawable/timer_bttn" 
    android:onClick="onClick"/>

QuestionActivity donde implementé el código del temporizador

public class QuestionActivity extends Activity implements OnClickListener{

    private Question currentQ;
    private GamePlay currentGame;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.question);
        /**
         * Configure current game and get question
         */
        currentGame = ((CYKApplication)getApplication()).getCurrentGame();
        currentQ = currentGame.getNextQuestion();
        Button nextBtn1 = (Button) findViewById(R.id.answer1);
        nextBtn1.setOnClickListener(this);
        Button nextBtn2 = (Button) findViewById(R.id.answer2);
        nextBtn2.setOnClickListener(this);
        Button nextBtn3 = (Button) findViewById(R.id.answer3);
        nextBtn3.setOnClickListener(this);
        Button nextBtn4 = (Button) findViewById(R.id.answer4);
        nextBtn4.setOnClickListener(this);
        /**
         * Update the question and answer options..
         */
        setQuestions();

    }


    /**
     * Method to set the text for the question and answers from the current games
     * current question
     */
    private void setQuestions() {
        //set the question text from current question
        String question = Utility.capitalise(currentQ.getQuestion());
        TextView qText = (TextView) findViewById(R.id.question);
        qText.setText(question);

        //set the available options
        List<String> answers = currentQ.getQuestionOptions();
        TextView option1 = (TextView) findViewById(R.id.answer1);
        option1.setText(Utility.capitalise(answers.get(0)));

        TextView option2 = (TextView) findViewById(R.id.answer2);
        option2.setText(Utility.capitalise(answers.get(1)));

        TextView option3 = (TextView) findViewById(R.id.answer3);
        option3.setText(Utility.capitalise(answers.get(2)));

        TextView option4 = (TextView) findViewById(R.id.answer4);
        option4.setText(Utility.capitalise(answers.get(3)));

        int score = currentGame.getScore();
        String scr = String.valueOf(score);
        TextView score1=(TextView) findViewById(R.id.score);
        score1.setText(scr);
    }


    @Override
    public void onClick(View arg0) {
        //Log.d("Questions", "Moving to next question");
        if(!checkAnswer(arg0)) return;  

        /**
         * check if end of game
         */
        if (currentGame.isGameOver()) {
            //Log.d("Questions", "End of game! lets add up the scores..");
            //Log.d("Questions", "Questions Correct: " + currentGame.getRight());
        //Log.d("Questions", "Questions Wrong: " + currentGame.getWrong());
        Intent i = new Intent(this, EndgameActivity.class);
        startActivity(i);
        finish();
        }
        else {

        finish();
        }
    }

    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        switch (keyCode)
        {
        case KeyEvent.KEYCODE_BACK :
            return true;
        }

        return super.onKeyDown(keyCode, event);
    }


    /**
     * Check if a checkbox has been selected, and if it
     * has then check if its correct and update gamescore
     */
    private boolean checkAnswer(View v) {

        Button b=(Button) v;
        String answer = b.getText().toString();

        //Log.d("Questions", "Valid Checkbox selection made - check if correct");
        if (currentQ.getAnswer().equalsIgnoreCase(answer))
        {
        //Log.d("Questions", "Correct Answer!");
        currentGame.incrementScore();
        }
        else {
        //Log.d("Questions", "Incorrect Answer!");
        currentGame.decrementScore();
        }

        return true;
    }

    public void setTimer() {
        long finishTime = 5;
        CountDownTimer counterTimer = new CountDownTimer(finishTime * 1000, 1000) {
            public void onFinish() {
                //code to execute when time finished
            }

            public void onTick(long millisUntilFinished) {
                int seconds = (int) (millisUntilFinished / 1000);
                int minutes = seconds / 60;
                seconds = seconds % 60;

                if (seconds < 10) {
                    txtTimer.setText("" + minutes + ":0" + seconds);

                }
            }
        };

    }
