                            } else if (isTimerRunning) {
                                 /*timer running alert dilaog*/

                            } else {
                                /*geyser off method*/
                                long millisInfuture=15000;
                                long countDownInterval=1000;
                                new CountDownTimer(millisInfuture,countDownInterval){
                                    public void onTick(long millisUntilFinished){
                                        Toast.makeText(context,"Seconds Remaining:"+millisUntilFinished/1000,Toast.LENGTH_LONG).show();
                                    public void onFinish(){
                                        Toast.makeText(context,"Time Over",Toast.LENGTH_LONG).show();


                    isProgrammatically = false;


  • You can proceed to use a TimerTask! Set the timer for 15 seconds and in execution toggle the checkbox and reset the timer again for 15 seconds.

        Timer timer = new Timer();
        final TimerTask task = new TimerTask() {
               public void run() {
                   myCheckBox.setChecked(!myCheckBox.isChecked()); //Toggle
        timer.scheduleAtFixedRate(task, 15*1000, 15*1000); //Schedule from delay 15 seconds
