public void setOffscreenPageLimit(int limit)
This is offered as an optimization. If you know in advance the number of pages you will need to support or have lazy-loading mechanisms in place on your pages, tweaking this setting can have benefits in perceived smoothness of paging animations and interaction. If you have a small number of pages (3-4) that you can keep active all at once, less time will be spent in layout for newly created view subtrees as the user pages back and forth.
You should keep this limit low, especially if your pages have complex layouts. This setting defaults to 1.

A fake drag can be useful if you want to synchronize the motion of the ViewPager
with the touch scrolling of another view, while still letting the ViewPager
control the snapping motion and fling behavior. (e.g. parallax-scrolling tabs.)
Call fakeDragBy(float)
to simulate the actual drag motion. Call
endFakeDrag()
to complete the fake drag and fling as necessary.
During a fake drag the ViewPager will ignore all touch events. If a real drag is already in progress, this method will return false.
