java - Issues with a tagging system using Autocomplete android -

i trying implement similar facebook's search system, if user starts typing in name brings autocomplete suggestions based on letters typed, , additional option search more results. each result object , not string, , have tried adding result search every time click on search or 1 of objects replace text occurs object oppose name , know method of autocomplete widget. there way go it?

here code:

private autocompletetextview sx;  sx = (autocompletetextview) findviewbyid(r.id.sx); if(sadapter == null) {     sadapter = new sadapter(postactivity.this, usersfound);     sx.setadapter(sadapter); }  sx.addtextchangedlistener(new textwatcher() {     @override     public void beforetextchanged(charsequence s, int start, int count, int after) {     }      @override     public void ontextchanged(charsequence s, int start, int before, int count) {         if (sx.gettext().tostring().length() <= 3 && sadapter != null) {             usersfound.clear();             sadapter.notifydatasetchanged();         }         if (sx.gettext().tostring().length() > 3) {             usersfound.clear();             sadapter.notifydatasetchanged();             log.d(constants.debug, "changing text " + s);                 sxname = s.tostring();              testcreate();             sadapter.notifydatasetchanged();         }     }      @override     public void aftertextchanged(editable s) {     } });  sx.setonitemclicklistener(new adapterview.onitemclicklistener() {     @override     public void onitemclick(adapterview<?> parent, view view, int position, long id) {          databaseuser newadd = usersfound.get(position);         if(position ==  searchserverindex) {             sx.settext(sxname);             usersfound.clear();             sadapter.notifydatasetchanged();             apigetpossiblecandidates();         } else {             sx.settext("");         }     } });  private void testcreate() {     databaseuser nuser1 = new databaseuser("userid", "pictureid", "jon");     databaseuser nuser2 = new databaseuser("userid", "pictureid", "jonny");     databaseuser nuser3 = new databaseuser("userid", "pictureid", "jong");     databaseuser nuser4 = new databaseuser("userid", "pictureid", "joan");     databaseuser searchserver = new databaseuser("searchid", "pictureid", "search " + sxname);      usersfound.add(nuser1);     usersfound.add(nuser2);     usersfound.add(nuser3);     usersfound.add(nuser4);     searchserverindex = usersfound.size();     usersfound.add(searchserver);      if(sadapter != null) {         sadapter.notifydatasetchanged();     } } 

this adapter:

public class sadapter extends arrayadapter<databaseuser> {  private context mcontext;     private list<databaseuser> userssearch;     private list<databaseuser> usersfiltered;      public sadapter(context context, list<databaseuser> usersadded) {         super(context, 0, usersadded);         mcontext = context;         userssearch = usersadded;     }      @override     public int getcount() {         return userssearch.size();     }     @override     public long getitemid(int position) {         return position;     }      @override     public view getview(int position, view convertview, viewgroup parent) {         view v = convertview;         if (v == null) {             layoutinflater inflater = (layoutinflater) mcontext                     .getsystemservice(context.layout_inflater_service);              v = inflater.inflate(r.layout.user_autosearch_item, null);         }          //helps recycling         final viewholder holder = new viewholder();          holder.usertxt = (textview) v.findviewbyid(r.id.usertxt);          v.settag(holder);              string name = userssearch.get(position).getname();             holder.usertxt.settext(name);           return v;     }      static class viewholder {         textview usertxt;     } } 

you can override getitem() method in adapater , return object of databaseuser of particular position searchlist..

@override public databaseuser getitem(int position) {      return userssearch.get(position);  } 

so onclick method can call method , give databaseuser object can retrive text. hope helps ..
