Is your question how to format a text to date/time or how to execute a UI operation every second? — Budius, Mar 06 '17 at 11:26

You can achieve from

int timeinminutes=1;

timer = new CountDownTimer(timeinminutes*21000, 1000) 
{

    TextView jeutimer = (TextView) findViewById(R.id.jeu_timer);

     public void onTick(long millisUntilFinished) 
     {
         long scnds=0;
         scnds=(millisUntilFinished/1000);
         jeutimer.setText( "" + scnds);        // Add your date here..
     }


     public void onFinish() 
     {

     }

}.start();

Now you will be able to restart it whenever you want with:

timer.start();

And stop it with:

timer.cancel();

Edited You can also use this ..

txtView.setText(parseDate("06/03/2017 01:20:00","dd/MM/yyyy hh:mm:ss","dd/MM/yyyy hh:mm:ss"));

public static String parseDate(String Date, String CurrentPattern, String OutputPattern) {

    SimpleDateFormat sdf = new SimpleDateFormat(CurrentPattern, Locale.getDefault());

    try {
        Date startDate = increaseDate(sdf.parse(Date));
        sdf.applyPattern(OutputPattern);
        return sdf.format(startDate);
    } catch (Exception e) {
        return "";
    }
}

public static Date increaseDate(Date origDate) {

    final Calendar calendar = Calendar.getInstance();

    calendar.setTime(origDate);
    calendar.add(Calendar.SECONDS, +1);
    Date newDate = calendar.getTime();
    return newDate;
}

i want to start from the date displayed in the text view, i have this date returned by a web service — Amalo, Mar 06 '17 at 11:34
