title: Android ListView/Gallery layout animation
body: <p>I'm working with gallery widget.
  I've attached layout animation that fades in element in gallery.
  It works well.</p>
  
  <p>But when I change content of gallery, and refresh adapter with notifyDataSetChanged();
  New elements show up, but there is no layout animation for them.</p>
  
  <p>How to implement that effect?
  I frequently update gallery content, and I need that effect every time.</p>
  
  <p>Here is a code:</p>
  
  <pre><code> &lt;com.rtrk.gui.mainmenu.gallery.A4TVGallery
      android:id="@+id/mainMenuGallery"
      android:layout_width="fill_parent"
      android:layout_height="wrap_content"
      android:layout_gravity="center"
      android:gravity="center"
      android:layoutAnimation="@anim/a4tv_gallery_controller"
      android:persistentDrawingCache="animation" /&gt;
  
  
  // Notify new data
  mainMenuAdapter.notifyDataSetChanged();
  
  // Set default selection
  
  mainMenuGallery.setSelection(defaultSelectedIndex);
  </code></pre>
  
  <p>TNX!</p>
