I have resolved my question. I replace the current fragment with itself, but before I have saved a reference of current fragment and then i close life cycle of current fragment invoking onDestroy(). I recall it with "newFragment" variable.
switch (item.getItemId()) {
case R.id.menu_refresh:
//THIS IS THE CODE TO REFRESH THE FRAGMENT.
FragmentManager manager = getActivity().getSupportFragmentManager();
FragmentTransaction ft = manager.beginTransaction();
Fragment newFragment = this;
this.onDestroy();
ft.remove(this);
ft.replace(container.getId(),newFragment);
//container is the ViewGroup of current fragment
ft.addToBackStack(null);
ft.commit();
return true;
}
