Android Studio automatic scroll to bottom when ScrollView expands?

Question

Is it possible to make my ScrollView automaically scroll to the bottom if the height expands? For example, if a Checkbox is checked and some views are then added to the ScrollView, they will be "below the current focus" and it might appear as if they were not added.

Answer 1

For automatically scrolling to add the code:

final ScrollView scrollview = ((ScrollView) findViewById(R.id.scrollview));
scrollview.post(new Runnable() {
    @Override
    public void run() {
        scrollview.fullScroll(ScrollView.FOCUS_DOWN);
    }
});

Answer 2

Runnable runnable=new Runnable() {
        @Override
        public void run() {
            scrollView.fullScroll(ScrollView.FOCUS_DOWN);
        }
    };
    scrollView.post(runnable);

call this lines every time after adding your view to your layout. That will lead you to initialize Runnable object once.
