Code of countdown timer-

counterTimer = new CountDownTimer(15000, 1000) {
        public void onFinish() {                
                if(currentGame.getRound()==20)
                {
                nextBtn1.setEnabled(false);
                nextBtn2.setEnabled(false);
                nextBtn3.setEnabled(false);
                nextBtn4.setEnabled(false);
                nextBtn5.setEnabled(false);
                final Handler handle = new Handler();
                Toast.makeText(QuestionActivity.this, "Time's Up", Toast.LENGTH_SHORT).show();
                Runnable delay = new Runnable() {
                    public void run() {
                        System.exit(0);
                    }
                };
                handle.postDelayed(delay,3000);
                }

                else if(currentGame.getRound()==0)
                {
                currentGame.decrementScore();
                final Handler handle = new Handler();
                Runnable delay = new Runnable() {
                    public void run() {
                        processScreen();
                    }
                };
                handle.postDelayed(delay,3000);
                }

                else if(currentGame.getRound()<=19)
                {
                        nextBtn1.setEnabled(false);
                        nextBtn2.setEnabled(false);
                        nextBtn3.setEnabled(false);
                        nextBtn4.setEnabled(false);
                        nextBtn5.setEnabled(false);
                        currentGame.decrementScore();
                        final Handler handle = new Handler();
                        Toast.makeText(QuestionActivity.this, "Time's Up", Toast.LENGTH_SHORT).show();
                        Runnable delay = new Runnable() {
                            public void run() {
                                processScreen();
                            }
                        };
                        handle.postDelayed(delay,3000);
                 }
            }

            public void onTick(long millisUntilFinished) {
                TextView time = (TextView) findViewById(R.id.timers);
                time.setText( ""+millisUntilFinished/1000);
                                }
        };
        counterTimer.start();
    }

Code for Dialog Box-

if(arg0.getId()==R.id.quit)
        {       
            Button yes, no;
            final Dialog dialog = new Dialog(this, R.style.FullHeightDialog); 
            dialog.setContentView(R.layout.dialog1); 
            dialog.setCancelable(true);
            counterTimer.cancel(); 
            //to set the message
            TextView message =(TextView) dialog.findViewById(R.id.tvmessagedialogtext);
            message.setText("Are you sure you want to Exit?");
            yes = (Button) dialog.findViewById(R.id.bmessageDialogYes);
            yes.setOnClickListener(new OnClickListener() {
            public void onClick(View v) 
            {
             finish();
             startActivity(new Intent(QuestionActivity.this, SplashActivity.class));             
                    }
            });

             no = (Button) dialog.findViewById(R.id.bmessageDialogNo);
             no.setOnClickListener(new OnClickListener() {
             public void onClick(View v)  
             {
             dialog.dismiss();
             nextBtn1.setEnabled(true);
             nextBtn2.setEnabled(true);
             nextBtn3.setEnabled(true);
             nextBtn4.setEnabled(true);
             }
             });
             dialog.show();
    }

Dialog Box Code-

    MyCounter timer;

    @Override

Just count the seconds yourself on each tick and use them later to create a new timer.

try like that

private final long interval = 1000;
long millisLeft = 90000;

public class MalibuCountDownTimer extends CountDownTimer {

        public MalibuCountDownTimer(long startTime, long interval) {
            super(startTime, interval);
        }

        @Override
        public void onFinish() {
            Toast.makeText(context, "Time's up!", Toast.LENGTH_LONG).show();
        }

        @Override
        public void onTick(long millisUntilFinished) {
            millisLeft = millisUntilFinished;
            System.out.println("The milies left is" + millisLeft);  
        }
    }

    @Override
    public void onResume() {
        super.onResume();

            countDownTimer = new MalibuCountDownTimer(millisLeft, interval);
            countDownTimer.start();
    }

    public void onPause() {
        super.onPause();
        countDownTimer.cancel();
    }
