building on comment, problem not providing arguments method call:

displayeventinvitationlist(layoutinflater inflater,viewgroup container); 

if extending fragment create class, 1 option store layoutinflater , viewgroup arguments oncreateview. save these class variables , use them in onoptionsitemselected.

//class variables layoutinflater inflater; viewgroup container; //... @override public view oncreateview (layoutinflater inflater, viewgroup container, bundle savedinstancestate) {     this.inflater = inflater;     this.container = container; }  //and in onoptionsitemselected... displayeventinvitationlist(inflater, container); 

failing that, need find way access appropriate layoutinflater , viewgroup object use arguments. layoutinflater relatively straight forward (i.e. layoutinflater li = layoutinflater.from(context);) , need access correct viewgroup layouts , widgets render.

also, way structured method call implies not understand java basics when comes method calls/declarations, essential understand android. so, recommend take time familiarise them.
