Spend one hour trying find how to access my list fragment as there was no explicit fragment ID

1. Get current select view page

ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
int id = viewPager.getCurrentItem();

2. Get Fragment by tag

Fragment frag = getFragmentManager().findFragmentByTag(“android:switcher:”+R.id.pager+”:”+id);

Then you can access your fragment reference.
