Support Library for Chronometer in Android

Question

If there any support Library function that could make the setCountDown function of the chronometer support by APIs lower than 24?

Answer 1

According to Android Documentation , its not possible with below API level 24. Chronometer widget only use count up. If you need to do so go with CountDownTimer.

For Example:

final int oneSecond = 1000; // in milliSeconds i.e. 1 second
final int tenSeconds = 100000; // 100 seconds
CountDownTimer cTimer =  new CountDownTimer(100000, oneSecond) {

     public void onTick(long millisUntilFinished) {

             int totalTime = 60000; // in milliseconds i.e. 60 seconds
             String v = String.format("%02d", millisUntilFinished/totalTime);
             int va = (int)( (millisUntilFinished%totalTime)/oneSecond);
             textView.setText("remaining seconds: " +v+":"+String.format("%02d",va));
     }

     public void onFinish() {
         textView.setText("done!");
     }
  };
  cTimer.start();
