try this code

YourFragment dFrag = (YourFragment) getSupportFragmentManager()
            .findFragmentById(R.id.detailfragment);

if (dFrag != null && dFrag.isInLayout()) {
    // do something
} else {
    // do something
}

Not sure if this would be an answer, but i'd recommend you to use FragmentTransaction like this:

FragmentManager fm = getFragmentManager();
FragmentTransaction ft = fm.beginTransaction();

if(yourOldFragment.isAdded()) {
    ft.replace(R.id.your_container, yourNewFragment);
    ft.commit();
}

You can also have a look this link : Fragment duplication on Fragment Transaction
