I wanted to first off introduce you to a widget called Viewpagerindicator by Jake Wharton if you haven't already come across it. It is a very popular viewpager extension.
You can download a demo from google play (this I recommend), search for "viewpager indicator"
To give you a back of the envelope solution, I would suggest you try creating at least 2 fragments and then page between them updating the text in on resume(). Do these fragment words need to be remembered? For instance if the user swipes back and forth are the same words meant to reappear?
