 Handler handler = new Handler();
    Runnable runnable = new Runnable() {
        @Override
        public void run() {
            FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
            if (activefragment == null)

            {
                fragmentTransaction.remove(activefragment);
            } else

            {
                fragmentTransaction.replace(R.id.fragmentContainer, activefragment, activefragment.getTag());
                fragmentTransaction.disallowAddToBackStack();
            }
            fragmentTransaction.commit();

        }
    };
    handler.postDelayed(runnable, timeout);

Here's a simple way to do it in Kotlin.

private lateinit var timer: Timer
private val noDelay = 0L
private val everyFiveSeconds = 5000L

override fun onResume() {
    super.onResume()

    val timerTask = object : TimerTask() {
        override fun run() {
            runOnUiThread { /* your code here */ }
        }
    }

    timer = Timer()
    timer.schedule(timerTask, noDelay, everyFiveSeconds)
}

override fun onPause() {
    super.onPause()

    timer.cancel()
    timer.purge()
}

You could use a handler, given example would call yourfunction() every second

// Init
private Handler handler = new Handler();
private Runnable runnable = new Runnable() {
    @Override
    public void run() {
        yourfunction();
        handler.postDelayed(this, 1000);
    }
};

//Start
handler.postDelayed(runnable, 1000);

Try to do like this ! just replace your code in startTimer method. It should work..

private Timer timer;
    private TimerTask timerTask;
    private Handler handler = new Handler();

    //To stop timer
   private void stopTimer(){
        if(timer != null){
            timer.cancel();
            timer.purge();
        }
    }

    //To start timer
    private void startTimer(){
        timer = new Timer();
        timerTask = new TimerTask() {
            public void run() {
                handler.post(new Runnable() {
                    public void run(){
                        //your code is here
                    }
                });
            }
        };
        timer.schedule(timerTask, 5000, 5000);
    }
