Restart fragment inside activity

问题

I have a litle doubt.

I have an activity that have 3 fragment inside. I need to restart the state of one of these fragments. Restart only one.

Old, but may be useful to someone else. To refresh the fragment, you need to detach the fragment and reattach it

Fragment frg = null;
frg = getFragmentManager().findFragmentByTag("Your_Fragment_TAG");
final FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.detach(frg);
ft.attach(frg);
ft.commit();

Your_Fragment_TAG is the name you gave your fragment when you created it
