android - Fragment Communication - selecting tabs and running methods in other tabs (Fragments) -


i have implemented tabbed action bar using android fragments (not support package). have button on 1 of tabs when pressed calls method in parent activity using interface.

the method in parent activity function change selected tab (fragment) , call method in tab.

i have interface allows 1 of fragments call method in parent activity

@override public void onchangetabbuttonselected(string billingid) {     int position = 1;  // selects 2nd tab     getactionbar().setselectednavigationitem(position);         ((fragmenttabsearchclients) searchclientstab).getclients(billingid);  }

this works fine , tab changed , method called appears fragment lifecycle has not been initiated correctly has method called getclients uses `getview()' returns null.

in parent class there way initialise tab before calling method on tab?
