title: ViewFlipper not flipping with child listview
body: <p>ViewFlipper is not working when swiping. If i put some other view instead of list view, flipping works fine. Is there any other code i should add for a listview? And scroll view inside view flipper also not working for me :(
  This is my xml code </p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;ViewFlipper xmlns:android="http://schemas.android.com/apk/res/android"
      android:id="@+id/vf"
      android:layout_width="fill_parent"
      android:layout_height="fill_parent"&gt;
  
      &lt;LinearLayout 
          android:layout_width="fill_parent"
          android:layout_height="match_parent"
          android:orientation="vertical"&gt;
  
          &lt;ListView
              android:id="@+id/list1"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent"/&gt;
      &lt;/LinearLayout&gt;
      &lt;LinearLayout 
          android:layout_width="fill_parent"
          android:layout_height="match_parent"
          android:orientation="vertical"&gt;
          &lt;ListView
              android:id="@+id/list2"
              android:layout_width="fill_parent"
              android:layout_height="fill_parent"/&gt;
      &lt;/LinearLayout&gt;
