java - Android : Issue deleting last item from RecyclerView -


i using recyclerview in following manner show list of places items updated in sqlite db .

the items deleted fine , updated swipe them . when swipe delete last item , comes in view . when close app , reopen app , item deleted though .

but when item swiped delete , in instance of app running , item not deleted view after swiping multiple times .

@override public void onswiped(recyclerview.viewholder viewholder, int swipedir) {      int swipedposition = viewholder.getadapterposition();      placelistadapter adapter = (placelistadapter) mrecyclerview.getadapter();       int pos = viewholder.getadapterposition();      // build appropriate uri string row id appended      string stringid = places.get(pos).getid();       log.d("testhro", stringid);       uri uri = placecontract.placeentry.content_uri;      uri = uri.buildupon().appendpath(stringid).build();       log.d("testhhd", uri.tostring());      // completed (2) delete single row of data using contentresolver      getcontentresolver().delete(uri, null, null);      madapter.notifydatasetchanged();      refreshplacesdata();  }

refreshplacesdata()

 private void refreshplacesdata() {         uri uri = placecontract.placeentry.content_uri;         cursor data = getcontentresolver().query(                 uri,                 null,                 null,                 null,                 null);          if (data == null || data.getcount() == 0) return;          log.d("countis", string.valueof(data.getcount()));          list<string> guids = new arraylist<string>();         while (data.movetonext()) {             guids.add(data.getstring(data.getcolumnindex(placecontract.placeentry.column_place_id)));         }         pendingresult<placebuffer> placeresult = places.geodataapi.getplacebyid(mclient,                 guids.toarray(new string[guids.size()]));         placeresult.setresultcallback(new resultcallback<placebuffer>() {             @override             public void onresult(@nonnull placebuffer places) {                 madapter.swapplaces(places);                 mainactivity.this.places = places;                 mgeofencing.updategeofenceslist(places);                 if (misenabled) mgeofencing.registerallgeofences();             }         });     }

am missing something? thanks.

edit : tried updating adapter instead of madapter , still no change

edit 2

public void swapplaces(placebuffer newplaces) {         mplaces = newplaces;         if (mplaces != null) {             // force recyclerview refresh             this.notifydatasetchanged();          }     }

note : verified loggers :

d/countiszero: true (inside refreshplacesdata())

you should refresh view after changing dataset.

   mainactivity.this.places = places; // data set changed    placelistadapter adapter = (placelistadapter) mrecyclerview.getadapter();    adapter.notifydatasetchanged();

or should change order of 

   madapter.notifydatasetchanged(); // notify later    refreshplacesdata(); // refresh first

firstly change dataset , notify adapter.
