Count animation up to down when using CountDownTimer class

Question

I want my countdown text animate up to down when counting like GIF file attached bellow. currently it animate like normal fade. I use CountDownTimer class to count and a TextView for timer. Here is code below:

//somecode
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    CountText=(TextView)findViewById(R.id.countText);
    CounterClass timer = new CounterClass(15000,1000);
    timer.start();
}

CounterClass.java

 public class CounterClass extends CountDownTimer {

     public CounterClass(long millisInFuture, long countDownInterval) {
         super(millisInFuture, countDownInterval);
     }

     @Override
     public void onTick(long millisUntilFinished) {
         millis = millisUntilFinished;
         String hms = String.format("%02d:%02d",
                    TimeUnit.MILLISECONDS.toMinutes(millis) - TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(millis)),
                    TimeUnit.MILLISECONDS.toSeconds(millis) - TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis)));
         System.out.println(hms);

         CountText.setText(hms);
      }

      @Override
      public void onFinish() {

      }

   }

Is there any way i can achieve this? Been trying to get past 2 days. I know there is solution by creating 4 different text and animate but i cant use it because of some reason. so Any help would be appreciated. Thanks!
