the main thing changed in class use extends fragment extends listfragment believe creating error although not sure how?

package com.tipa.uips;  import com.tipa.uips.r; import android.os.bundle; import android.support.v4.app.listfragment; import android.view.layoutinflater; import android.view.view; import android.view.viewgroup; import android.content.context; import android.widget.arrayadapter; import android.widget.imageview; import android.widget.listview; import android.widget.textview; import android.widget.toast;  public class friendslist extends listfragment {       public class mylistadapter extends arrayadapter<string> {        context mycontext;        public mylistadapter(context context, int textviewresourceid,         string[] objects) {        super(context, textviewresourceid, objects);        mycontext = context;       }        @override       public view getview(int position, view convertview, viewgroup parent) {        //return super.getview(position, convertview, parent);         layoutinflater inflater =           (layoutinflater)mycontext.getsystemservice(context.layout_inflater_service);        view row=inflater.inflate(r.layout.row, parent, false);        textview label=(textview)row.findviewbyid(r.id.carrottop);        label.settext(month[position]);        imageview icon=(imageview)row.findviewbyid(r.id.dp);         //customize icon here        icon.setimageresource(r.drawable.dp);         return row;       }       }       string[] month ={        "^smithy",         "^kreso",         "^chen",         "^dave"      };       @override      public void oncreate(bundle savedinstancestate) {       super.oncreate(savedinstancestate);        /*       listadapter mylistadapter = new arrayadapter<string>(         getactivity(),         android.r.layout.simple_list_item_1,         month);       setlistadapter(mylistadapter);       */       mylistadapter mylistadapter =          new mylistadapter(getactivity(), r.layout.row, month);       setlistadapter(mylistadapter);      }       @override      public view oncreateview(layoutinflater inflater, viewgroup container,        bundle savedinstancestate) {       return inflater.inflate(r.layout.friends_list, container, false);      }       @override      public void onlistitemclick(listview l, view v, int position, long id) {       toast.maketext(         getactivity(),          getlistview().getitematposition(position).tostring(),          toast.length_long).show();      }      } 

this here adapter allow fragments return values of each class believing not allowing it.

package com.tipa.uips;  import com.tipa.uips.newsfeed; import com.tipa.uips.chat; import com.tipa.uips.friendslist; import android.support.v4.app.fragment; import android.support.v4.app.fragmentmanager; import android.support.v4.app.fragmentpageradapter;  public class tabspageradapter extends fragmentpageradapter {      public tabspageradapter(fragmentmanager fm) {         super(fm);     }      @override     public fragment getitem(int index) {          switch (index) {         case 0:             // top rated fragment activity             return new newsfeed();         case 1:             // games fragment activity             return new chat();         case 2:             // movies fragment activity             return new friendslist();         }          return null;     }      @override     public int getcount() {         // item count - equal number of tabs         return 3;     }  } 

cheers

friends_list.xml

<?xml version="1.0" encoding="utf-8"?> <linearlayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:orientation="vertical" >     <listview         android:id="@+id/list"         android:layout_width="match_parent"         android:layout_height="wrap_content" >     </listview>  </linearlayout> 

you need have listview id below in friends_list.xml

<listview android:id="@android:id/list" 

whatever applies listactivity applies listfragment. more info @

quoting docs

listactivity has default layout consists of single, full-screen list in center of screen. however, if desire, can customize screen layout setting own view layout setcontentview() in oncreate(). this, own view must contain listview object id "@android:id/list" (or list if it's in code)

so if inflate layout in listfragment need have listview id @android:id/list in fragments layout.

edit:

notice android:id="@+id/list" vs android:id="@android:id/list". suggested android:id="@android:id/list"
