android - Values are not Populating in Listview -

-

this question has answer here:

i trying develop android application can display values multiple tables.

i have used base adapter display values since need display queried values in list. when try display values in list view blank.

i not sure have done wrong.

i using below method query data database display required values.

  public cursor getassetinstore()     {          sqlitedatabase db_database = getreadabledatabase();          cursor c  = db_database.rawquery("select asset_name,warrenty,assetimage,asset_status `assets`,`aseetissued` assets.assetid = aseetissued.assetissuedid , asset_status =?" ,                 new string [] {"in storage"}, null);         return c;      }

the below methods used populate values onto list view.

private void populateassetlistview()     {          cursor c = db_database.getassetinstore();         assetlistview.setadapter(new assetlistadapter(this, c));       }       public class assetlistadapter  extends baseadapter     {          private context mcontext;         cursor cursor;          public assetlistadapter(context context, cursor c) {             super();              mcontext = context;             cursor =c ;          }           @override         public int getcount() {             return 0;         }          @override         public object getitem(int position) {             return null;         }          @override         public long getitemid(int position) {             return 0;         }          @override         public view getview(int position, view view, viewgroup parent) {              layoutinflater inflater = (layoutinflater) mcontext.getsystemservice(context.layout_inflater_service);            //the layout assigned custome created created in case customeassetview cales displayed per list             view = inflater.inflate(r.layout.assetsinstore_placeholder, null);              cursor.movetoposition(position);              textview assetsstatus = (textview) view.findviewbyid(r.id.assetssatutsstore_view);             int status = cursor.getint(cursor.getcolumnindex("asset_status"));             assetsstatus .settext(string.valueof(status));              textview assetsname = (textview) view.findviewbyid(r.id.assetstore_name_view);             string assetname = cursor.getstring(cursor.getcolumnindex("asset_name"));             assetsname.settext(assetname);              textview warrenty = (textview) view.findviewbyid(r.id.assetstore_warrenty_view);             string custdesignation = cursor.getstring(cursor.getcolumnindex("warrenty"));             warrenty .settext(custdesignation);               imageview assetimage = (imageview) view.findviewbyid(r.id.list_image);              byte[] bb = cursor.getblob(cursor.getcolumnindex("assetimage"));             assetimage.setimagebitmap(bitmapconver.getphoto(bb));              return view;         }     }

try use cursor adapter in place of base adapter. moreover, beware position you're passing cursor may not think.

javascript - Create websocket without connecting -

-
is there way create websocket without connecting right away? far think var ws = new websocket("ws://ws.my.url.com"); creates , connects right away. i'd create socket, define callbacks, , connect once user clicks connect button. thanks no. creating websocket means you've created connection server (or started process of connecting). there no such thing creating websocket isn't connecting yet. you create object store configuration parameters , tell object connect when wanted to, though i'm not sure why that's better creating actual websocket when connect made. or create function setup work , call function later when user clicks connect button.
