actually it is 3. view pager always load 3 pages or to be exact 3 fragments into memory. this insures user doesn't encounter a frame drop. but there is a catch:
we have two kind of view pager adapter: FragmentPagerAdapter and FragmentStatePagerAdapter .
if you have fragments with heavily content i suggest FragmentStatePagerAdapter because it doesn't load all 3 fragments together. it loads the first one and the save only the states of the other two. its better in case you want to manage memory for heavily content Fragments
