android - Return to a fragment stateless -


i have 3 fragments a, b(with search) , c. want fragment b on key pressed c, not retained state/with nothing in search bar precisely.

here did:

public class fragcount extends fragment{  //expandablelistadapter listadapter; // searchableadapter listadapter; expandablelistview explistview; list<string> listdataheader; hashmap<string, list<string>> listdatachild; private int groupid = -1; public static edittext searchtext;  @override public view oncreateview(layoutinflater inflater,viewgroup container, bundle args) {       view view = inflater.inflate(r.layout.country_main, container, false);     setretaininstance(true);      // listview     explistview = (expandablelistview) view.findviewbyid(r.id.lvexp);      // preparing list data     preparelistdata();      listadapter = new searchableadapter(getactivity(), listdataheader, listdatachild);      // setting list adapter     explistview.setadapter(listadapter);      explistview.setonchildclicklistener(new expandablelistview.onchildclicklistener() {          public boolean onchildclick(expandablelistview parent, view v,                                     int groupposition, int childposition, long id) {             final string selected = (string) listadapter.getchild(                     groupposition, childposition);              values.language = selected;              getactivity().getwindow().setsoftinputmode(                     windowmanager.layoutparams.soft_input_state_always_hidden);             explistview.collapsegroup(-1);             bundle args = new bundle();             args.putstring("menu", selected);             args.putint("serial",childposition);             fragment c = new infoshow();             c.setarguments(args);              explistview.collapsegroup(groupid);

calling fragment c

            fragmentmanager fragmentmanager = getfragmentmanager();              fragmentmanager.begintransaction().replace(r.id.content_frame,c).addtobackstack(null).commit();               return true;         }     });      searchtext = (edittext) view.findviewbyid(r.id.inputsearch);      searchtext.addtextchangedlistener(new textwatcher() {          @override         public void beforetextchanged(charsequence charsequence, int i, int i2, int i3) {          }          @override         public void ontextchanged(charsequence charsequence, int i, int i2, int i3) {          }          @override         public void aftertextchanged(editable editable) {             fragcount.this.listadapter.getfilter().filter(editable.tostring());             listadapter.notifydatasetchanged();             explistview.invalidateviews();             explistview.collapsegroup(groupid);         }     });     ((actionbaractivity) getactivity()).getsupportactionbar().settitle("select country");      explistview.setongroupexpandlistener(new expandablelistview.ongroupexpandlistener() {         int previousgroup = -1;          @override         public void ongroupexpand(int groupposition) {             if(groupposition != previousgroup)               explistview.collapsegroup(previousgroup);             previousgroup = groupposition;             groupid = previousgroup;         }     });      return  view; }
