I\'ll keep the question as short and simple as humanly possible.
View activeView = mViewPager.getChildAt(mViewPager.getCurrentItem());

How many child views should the be?
Also a ViewPager doesn't have all childs loaded at the same time. Only the one it is showing and the next one. You can use mViewPager.setOffscreenPageLimit() to, for example 3 or 4, to 'preload' more items into the viewpager.
mViewPager.setOffscreenPageLimit()
