Getting the current Fragment instance in the viewpager

Question

Below is my code which has 3 Fragment classes each embedded with each of the 3 tabs on ViewPager. I have a menu option. As shown in the onOpt

Answer 1

To get current fragment - get position in ViewPager at public void onPageSelected(final int position), and then

public PlaceholderFragment getFragmentByPosition(Integer pos){
    for(Fragment f:getChildFragmentManager().getFragments()){
        if(f.getId()==R.viewpager && f.getArguments().getInt("SECTNUM") - 1 == pos) {
            return (PlaceholderFragment) f;
        }
    }
    return null;
}

SECTNUM - position argument assigned in public static PlaceholderFragment newInstance(int sectionNumber); of Fragment

getChildFragmentManager() or getFragmentManager() - depends on how created SectionsPagerAdapter
