android - why my adapter can't refresh it's view -


below adapter code , logs (log tag "jieke"), problem times can't display whole items in list, display 8 items meanwhile list size 10! see in log: getcount returns 10, getview called 10 times, still seen 8 views, why?

public class numberadapter extends baseadapter{     private layoutinflater minflater;     private arraylist<numbermodel> mphonenumberlist;      public numberadapter(context context, arraylist<numbermodel> phonenumberlist){         minflater = layoutinflater.from(context);         mphonenumberlist = phonenumberlist;     }      @override     public int getcount() {         if (mphonenumberlist != null) {             logutils.d("jieke", "count="+mphonenumberlist.size() );             return mphonenumberlist.size();         }         return 0;     }      @override     public object getitem(int position) {         if (position > -1 && mphonenumberlist != null && position < mphonenumberlist.size()) {             return mphonenumberlist.get(position);         }         return null;     }      public void setphonenumberlist(arraylist<numbermodel> phonenumberlist){         mphonenumberlist = phonenumberlist;     }      @override     public long getitemid(int position) {         return position;     }      @override     public view getview(int position, view convertview, viewgroup parent) {         logutils.d("jieke", "get view on position= " +position );         itemviewtag viewtag;         if (convertview == null)  {               convertview = minflater.inflate(r.layout.grid_item_custom_number, null);             viewtag = new itemviewtag((imageview) convertview.findviewbyid(r.id.item_image)                 ,(imageview) convertview.findviewbyid(r.id.item_phone)                 , (textview) convertview.findviewbyid(r.id.item_text));               convertview.settag(viewtag);           } else {               viewtag = (itemviewtag) convertview.gettag();           }         return convertview;       }      class itemviewtag {          protected imageview micon;           protected imageview mphone;         protected textview mname;         public itemviewtag(imageview icon, imageview phone, textview name){               this.mname = name;               this.micon = icon;               this.mphone = phone;       }   }

}

actually, need refresh gridview after mphonenumberlist changed (after mphonenumberlist.add() or mphonenumberlist.remove()) found using numberadapter.notifydatasetchanged() not work, every time create new adapter , reset gridview using gridview.setadapter(newnumberadapter), works , problem happened.

problem solved, after gridview.setadapter(newnumberadapter) add gridview.invalidateviews() works me!

i believe using asynctask.intialise arraylist arraylist<numbermodel> mphonenumberlist(which sending argument in constructor of adapter) in doinbackground(string... params) of asynctask like: mphonenumberlist=new arraylist<numbermodel> instead of creating instance in oncreate().

try solution.i believe adapter refreshed.

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
