body: <p>hello I have a view with a title at top and a listView with pulltorefresh functionality.</p>
  
  <p>I would like to show the line separator before the first item in the listView:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="fill_parent"
     android:layout_height="fill_parent"
     android:background="@drawable/background_azul"
     android:orientation="vertical" &gt;
  
  &lt;RelativeLayout 
      android:orientation="horizontal"
      android:layout_width="fill_parent"
      android:layout_height="50dip"
      android:background="@color/usualBike"
  &gt;
  
      &lt;TextView
          android:id="@+id/noticesLabel"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_alignParentTop="true"
          android:layout_centerHorizontal="true"
          android:gravity="center"
          android:text="@string/tituloNoticias"
          android:textColor="@color/white"
          android:textSize="30dip"
          android:textStyle="bold" /&gt;
  
  
  &lt;/RelativeLayout&gt;
  
  &lt;View
      android:id="@+id/View01"
      android:layout_width="fill_parent"
      android:layout_height="2dp"
      android:background="#3b5998"/&gt;
  
  &lt;com.mypackage.myapp.PullToRefresh
      android:id="@+id/listNews"
      android:layout_width="fill_parent"
      android:layout_height="fill_parent" 
      android:cacheColorHint="#00000000"
      android:layout_marginLeft="8dip"
      android:layout_marginRight="8dip"
      android:divider="#3b5998"
      android:dividerHeight="2dip"/&gt;           
  
  &lt;/LinearLayout&gt; 
  </code></pre>
