When we use the viewPager, a good way to access the fragment instance in activity is instantiateItem(viewpager,index). //index- index of fragment of which you want instance.

for example I am accessing the fragment instance of 1 index-

Fragment fragment = (Fragment) viewPageradapter.instantiateItem(viewPager, 1);

if (fragment != null && fragment instanceof MyFragment) {      
 ((MyFragment) fragment).callYourFunction();

}
