回答1:

If your application is to stay responsive you need to do this in another thread. Or you could simply create a timer and schedule it.

Whatever thread you're in when you tell it to sleep - will impeccably do so...

Something like this:

Timer timer = new Timer();
TimerTask myTask = new TimerTask() {
    @Override
    public void run() {
        // whatever you need to do every 2 seconds
    }
};

timer.schedule(myTask, 2000, 2000);
