how incorporate adapter volley?

first, think need fix url, add adapter arraylist

second, second parameter arrayadapter needs layout contains id of android:id/text1 if aren't going provide additional arguments (it's fine didn't know that, buried in documentation). being said, there's built-in layout single textview 

    //get listview      listview listview = (listview) findviewbyid(r.id.mobile_list);     // make adapter , set     final arrayadapter<string> adapter = new arrayadapter<string>(this, android.r.layout.simple_list_item_1);     listview.setadapter(adapter);      // volley things      final jsonobjectrequest obj= new jsonobjectrequest(request.method.get, jsonurl, new response.listener<jsonobject>() {         @override         public void onresponse(jsonobject response) {             try {                 // parse response                  response = response.getjsonobject("data");                  // add things adapter                  adapter.add(response.tostring());
