android - Loadmore ListView Or RecyclerView -


i'm doing loadmore listview. when scrolled last item, event done loadmore. runs fine except 1 problem, complete data loadmore additional adapter can still recognize new adapter made scratch when see listview reloads rather appended listview earlier. class:

public class storylistmenu extends activity{      private string url;     listview listviewstory;     private storylistmenuadapter adapter;     private list<storymenu> liststory;     private progressbar progressbar;     private view progressloadmore;     private boolean loadmorestatus;     private boolean enableloadmore;     private int page;     private int currentitem;      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.layout_story_list_menu);          page = 0;         loadmorestatus = true;         enableloadmore = true;         currentitem = 0;          progressbar = (progressbar) findviewbyid(r.id.progress_story_list_menu);         progressbar.setvisibility(view.visible);         progressloadmore = ((layoutinflater) this.getsystemservice(context.layout_inflater_service)).inflate(r.layout.progress_row, null, false);          url = getintent().getstringextra("url");           listviewstory = (listview) findviewbyid(r.id.listview_story_list_menu);         listviewstory.setdivider(null);         liststory = new arraylist<storymenu>();          listviewstory.setonscrolllistener(new onscrolllistener() {             @override             public void onscrollstatechanged(abslistview view, int scrollstate) {}             @override             public void onscroll(abslistview view, int firstvisibleitem,                     int visibleitemcount, int totalitemcount) {                 if(loadmorestatus && totalitemcount > 0 && firstvisibleitem + visibleitemcount == totalitemcount) {                     loadmorestatus = false;                     page += appconfig.pagesize;                     currentitem = firstvisibleitem;                     listviewstory.addfooterview(progressloadmore);                     new getstorylist().execute();                 }             }         });           new getstorylist().execute();     }      private class getstorylist extends asynctask<void, void, void> {          @override         protected void onpreexecute() {             super.onpreexecute();         }          @override         protected void doinbackground(void... params) {              ....                  liststory.add(...);   // data added here             ....             return null;         }          @override         protected void onpostexecute(void result) {             super.onpostexecute(result);              adapter = new storylistmenuadapter(liststory, getapplicationcontext());             listviewstory.setadapter(adapter);             progressbar.setvisibility(view.gone);              if(listviewstory.getfooterviewscount() > 0) {                 listviewstory.removefooterview(progressloadmore);                 if(enableloadmore)                     listviewstory.setselection(currentitem + 1);                 else                     listviewstory.setselection(currentitem);             }              loadmorestatus = true;         }      } } 

i encountered similar problems recyclerview. looked not find way how add data listview adapter users not notice refresh of listview adapter. have ideas me?

**update: add item in liststory notifydatasetchanged(). worked fine in listview not work in recyclerview. in `recyclerview' have method update data in recycleradapter:

public void additem(int position, storymenu item) {    liststory.add(position, item);    notifyiteminserted(position);   } 

and call additem method after more data.

you have check if adapter == null , them create new one, if not null can execute adapter.add(items) , notifydatasetchanged() refresh listview, reyclerview.
