title: How to align LinearLayout at the center of its parent?
body: <p>I've looked through numerous similar questions here at SO, but nothing helps.
  I have a hierarchy of different nested layouts, all have <code>android:layout_width="fill_parent"</code>, and the inner-most layout has <code>android:layout_width="wrap_content</code> - I need to align it at the center (horizontally). How do I do that?</p>
  
  <p><strong>Update:</strong>: I've found the cause of the problem - if I put the inner LinearLayout into RelativeLayout with <code>android:layout_width="fill_parent"</code>, it still wraps it's content. The TableRow, however, is really filling the screen.</p>
