android - XML layout has a ListView - But still getting ListView id not found exception -

i see lot of questions being asked in stackoverflow on same topic, could not understand deep problem of exception.

below xml layout. have listview.

<?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" android:background="#ffffff">      <listview         android:id="@+id/list"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:background="#656565"         android:paddingleft="@dimen/list_padding"         android:paddingright="@dimen/list_padding"          android:dividerheight="20.0sp"         android:divider="#656565"/>  </linearlayout> 

below fragment class.

public class fragmentclass extends sherlocklistfragment implements asynclistner{      @override     public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) {                 return inflater.inflate(r.layout.documents, container, false);     }      @override     public void onactivitycreated(bundle savedinstancestate){      }        @override       public void onloadcomplete(list<documentresponse> data) {                      documentsadapter adapter = new documentsadapter(getsherlockactivity(),                     r.id.list, data);           setlistadapter(adapter);       }  } 

once onloadcomplete call finished, trying create listview. error. "your content must have listview id attribute android.r.id.list"

change android:id="@+id/list" android:id="@android:id/list"

with using requested android.r.id.list id.

don't forget update code, too

documentsadapter adapter = new documentsadapter(getsherlockactivity(), android.r.id.list, data);
