Update TextView every second in Android [duplicate]

Answer 1

I've added some logics to stop the Timer. If you have any qyestion, ask freely

private int m = 0;
private int milliseconds = 1000;

public void loopMethod(int m){
  timer=(TextView) findViewById(R.id.timerText);
  Timer t = new Timer();

  //schedule a timer
  t.scheduleAtFixedRate(new TimerTask() {
    @Override
    public void run() {      
      runOnUiThread(new Runnable() {              
        @Override
        public void run() {
          timer.setText(String.valueOf(m));//avoid using composite string in the setText
          System.out.println(String.valueOf(m));

          //remove from the total the amount of millisecond passed
          m=m-milliseconds;
          if(m <= milliseconds) { //or <= what you want
            //stop the timer repeatitions
            t.cancel();
          }
        }
      });
    }
  //"0" is the amount of time to wait for the timer to start
  //"milliseconds" is the duration
  },0,milliseconds);
}

For a correct analysis you should add more infos in your question. the problem of not-updating textview might be caused by the setText("" + int) because it's always better to avoid the setText with an int. I edited it with String.valueOf, but if it's not working you should add the xml and the onCreate

Hope this helped
