I think you want to refresh the fragment contents upon db update
If so, detach the fragment and reattach it
// Reload current fragment
Fragment frg = null;
frg = getSupportFragmentManager().findFragmentByTag("Your_Fragment_TAG");
final FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.detach(frg);
ft.attach(frg);
ft.commit();
Your_Fragment_TAG is the name you gave your fragment when you created it
This code is for support library.
If you're not supporting older devices, just use getFragmentManager instead of getSupportFragmentManager
[EDIT]
This method requires the Fragment to have a tag.
In case you don't have it, then @Hammer's method is what you need.
