Here I am doing it using Handler but it only increments a number once. I want it to increment the number until I stop it using handler.removeCallbacksAndMessages(null);.

Can anyone please guide me how can I achieve this. I am just new to android.

   Handler handler;
handler = new Handler();
 handler.postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        count++;

                    }
                }, 1000);

Define a Thread a start it.

   Thread counterThread=new Thread(()->{
            try{
                while(true){
                counter++;
                Thread.sleep(1000);
                }
            }
            catch (Exception e){

            }
        });
    counterThread.start();

And when you want to stop this thread call counterThread.interrupt();

Android · GNOME · IBM AIX · iOS · Linux · Mac OS X · Office 365 · OpenBSD · Ubuntu · Unix · Windows 10 · Windows for(;;) { try { Thread.​sleep(1000); count ++; } catch (InterruptedException e) { you can also use Timer eg. Call the CounterController only from your test program. The controller will create an instance of CounterModel with the initial value and call increment until the end value is reached. The CounterModel will wait 1 second, increment its counter and then display its counter by calling CounterView. Use Thread.sleep(1000); to delay 1 second.

Head First Android Development: A Brain-Friendly Guide, The runTimer() method The next thing we need to do is create the runTimer() method. it increments the seconds variable and updates the text view every second.
