Question

I would like to start repeating two lines of code every 5 seconds when I press the button START and end it, when I press the button STOP. I was trynig with a TimerTask and H

Answer 1

You can use RxJava2/RxAndroid2 and create an Observable that emits a message every second (or whatever you want), example with pseudo code:

Disposable timer = Observable.interval(1000L, TimeUnit.MILLISECONDS)
            .timeInterval()
            .subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe(new Consumer>() {
                @Override
                public void accept(@NonNull Timed longTimed) throws Exception {               
                    //your code here.
                    Log.d(TAG, new DateTime());
                }
            });

When you want to stop it, you can simply call:

timer.dispose();

I find this code much more readable than the other options.
