Get fragment object in activity while using viewPagerviewpager

Recently, I was trying to know How to swipe through fragments using a ViewPager. I have to set text on a TextView which is in Fragement from the activity. I found that one can get the Fragment object from ViewPager using :

getSupportFragmentManager().findFragmentByTag("android:switcher:" + R.id.pager + ":0");

When I tried to do this in onCreate() method of activity, it always returns null. I assume that is because Fragment is not started yet. Then in which method I should try to access the fragment object so that I can send arguments to the fragment methods?

If you have a ViewPager and you want to access to a fragment which is inside a ViewPager, you can use this code:

Fragment currentFragment = (Fragment) viewPager.getAdapter().instantiateItem(viewPager, viewPager.getCurrentItem()); //gets current fragment
//now you have to cast it to your fragment, let's say it's name is SenapatiFragment

((SenapatiFragment)currentFragment).someMethod(...); // you have now access to public fields and methods that are inside your fragment
