Last active April 6, 2021 03:26
Observer pattern for notifying Fragments of a ViewPager to update their views. This will update the current Fragment, as well as the off screen Fragments that are retained.
public class FragmentObserver extends Observable {
@Override
public void notifyObservers() {
setChanged(); // Set the changed flag to true, otherwise observers won't be notified.
super.notifyObservers();
}
}
