-
Image
this confuses me lot. i had 2 fragments, , use fragmenttransaction.replace() swap 2 fragments. state of input controls radiogroup , checkbox preserved when switch other fragments , switch again. . i set break point on oncreateview() of fragment, , every swap seems trigger method , new views created each time. savedinstancebundle null well. since new views created, how state of old views? public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) { view v = inflater.inflate(r.layout.fragment_fieldsetup_marking, container, false); // ... return v; } this effect fine app, want know how implemented. where states stored? where android sdk code restore (i can not find in class fragmenttransection).
