title: ViewPager detect when user is trying to swipe out of bounds
body: <p>I am using the ViewPager consisting of 6 pages to display some data. I want to be able to call a method when the user is at position 0 and tries to swipe to the right (backwards), or at position 5 and tries to swipe to the left (forward), even though no more pages exist for these directions. Is there any way I can listen for these scenarios?</p>
