xml of listview of listfragment

<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:ads="http://schemas.android.com/apk/res-auto"     android:orientation="vertical"     android:layout_width="match_parent"     android:layout_height="match_parent">       <listview android:id="@id/android:list"         android:layout_width="fill_parent"         android:layout_height="fill_parent"         android:layout_weight="1.0"         android:layout_margintop="50dp"/>    </linearlayout> 

this listfragment class:

public class favouritesactionbar extends listfragment {       private static final string background_color = "color";     private static final string index = "index";      private string title;     private int page;     private adview madview;     private adrequest adrequest;     private databasewrapper database;       public static favourites newinstance(int color, string title) {          favourites fragment = new favourites();          bundle bundle = new bundle();         bundle.putint(background_color, color);         bundle.putstring("sometitle", title);         fragment.setarguments(bundle);         fragment.setretaininstance(true);          return fragment;      }      @override     public void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         page = getarguments().getint("someint", 0);         title = getarguments().getstring("sometitle");         database = new databasewrapper(getcontext());      }      @override     public void onactivitycreated(bundle savedinstancestate) {         super.onactivitycreated(savedinstancestate);       }      @override     public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) {          viewgroup rootview = null;         final string[] name;         final string[] url;          database.getalldata();          name = new string[database.getalldata().size()];         url = new string[database.getalldata().size()];          list<map<string, string>> list = new arraylist<map<string, string>>();         map<string, string> map;          (int = 0; < database.getalldata().size(); i++) {             name[i] = database.getalldata().get(i).getname();             url[i] = database.getalldata().get(i).geturl();              rootview = (viewgroup) inflater.inflate(r.layout.fragment_listview, container, false);              map = new hashmap<string, string>();             map.put("name", name[i]);             map.put("url", url[i]);             list.add(map);              simpleadapter adapter = new simpleadapter(getactivity(), list, r.layout.favourites, new string[] { "name", "url" }, new int[] { r.id.newspapernamefavourite, r.id.passurl });             setlistadapter(adapter);             setretaininstance(true);         }          return rootview;     }      @override     public void onlistitemclick(listview l, view view, int position, long id){         textview tv2=(textview)view.findviewbyid(r.id.passurl);          intent myintent = new intent(getactivity(), webview.class);         myintent.putextra("_url", tv2.gettext().tostring());         startactivity(myintent);     }  } 

try this:

1: create new activity. 2: paste in new activity in oncreate:

 fragment fr = new favouritesactionbar();         fragmentmanager fm = getfragmentmanager();         fragmenttransaction fragmenttransaction = fm.begintransaction();         fragmenttransaction.replace(r.id.fragment_place, fr);         fragmenttransaction.commit(); 

3:in xml of new activity:

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     android:orientation="vertical"     android:layout_width="match_parent"     android:layout_height="match_parent">       <fragment     android:name="com.yourpackage.favouritesactionbar"     android:id="@+id/fragment_place"     android:layout_width="match_parent"     android:layout_height="match_parent"/>  </linearlayout> 

4: in mainactivity in onoptionsitemselected:

intent intent = new intent(this, yournewactivitycreateinpoint1.class);             startactivity(intent);
