title: What is android:layout_gravity="clip_vertical" exactly
body: <p>The property <code>android:layout_gravity="clip_vertical|horizontal"</code> does the following as mentioned in the <strong>SDK</strong> documentation:</p>
  
  <blockquote>
    <p>Additional option that can be set to
    have the top and/or bottom edges of
    the child clipped to its container's
    bounds. The clip will be based on the
    vertical gravity: a top gravity will
    clip the bottom edge, a bottom gravity
    will clip the top edge, and neither
    will clip both edges.</p>
  </blockquote>
  
  <p>But I can't see anything of this in my applications,</p>
  
  <p>so what is the purpose of this property exactly ?</p>
  
  <p>thanks</p>
