How to set timer in android?

Question

Can someone give a simple example of updating a textfield every second or so?

I want to make a flying ball and need to calculate/update the ball coordinates every se

I think you can do it in Rx way like:

 timerSubscribe = Observable.interval(1, TimeUnit.SECONDS)
            .subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe(new Action1() {
                @Override
                public void call(Long aLong) {
                      //TODO do your stuff
                }
            });

And cancel this like:

timerSubscribe.unsubscribe();
