title: Android tabHost is invisable? Why won't it show with this XML?
body: <p>In my XML editor on Eclipse I see the tabhost, and it looks exactly how I want it, but when I run it I don't see the tabHost at all, how can I make sure it's visable?    </p>
  
  <p>This is my XML. Again, the editor shows it, but when I run it it doesn't, the activity which inflates it doesn't do much yet, just change the two textfields. Any ideas?</p>
