运行时错误与片段活动

我试图重新创建FragmentPagerSupport示例，但我不断收到错误，我不知道它的要求。运行时错误与片段活动

它这样做

@Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
      Bundle savedInstanceState) { 
     View v = inflater.inflate(R.layout.fragment_pager_list, container, false); 
     View tv = v.findViewById(R.id.text); 
     ((TextView)tv).setText("Fragment #" + mNum); 
     return v; 
    }

然后抛出运行时错误

这是我fragment_pager_list

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
android:id="@+id/layout"> 

<TextView 
    android:id="@+id/text" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_alignParentTop="true" 
    android:layout_centerHorizontal="true" 
    android:layout_marginTop="60dp" 
    android:text="Large Text" 
    android:textAppearance="?android:attr/textAppearanceLarge" /> 



<ListView 
    android:id="@+id/list" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:layout_below="@+id/text" 
    android:layout_centerHorizontal="true" > 

</ListView> 

</RelativeLayout>

，这是我的主要

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
android:orientation="vertical" > 

<android.support.v4.view.ViewPager 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:id="@+id/pager"/> 
</LinearLayout>
