Answer 1

one has to instance the FragmentPagerAdapter first, then .getCount() will return a value -

while .getCount() - 1 should be set as the default off-screen limit:

TabsPagerAdapter adapter = new TabsPagerAdapter(getSupportFragmentManager());

/* the ViewPager requires a minimum of 1 as OffscreenPageLimit */
int limit = (adapter.getCount() > 1 ? adapter.getCount() - 1 : 1);

ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
viewPager.setAdapter(adapter);
viewPager.setOffscreenPageLimit(limit);
