title: Why is my TabHost's FrameLayout's only child loaded with visibility = View.GONE?
body: <p>I'm using a TabHost to render some tabs. In the XML definition everything is set up ~normally, a RelativeLayout is the only child of the FrameLayout for the TabHost. </p>
  
  <p>Weirdly, that relative layout always loads up as View.GONE. Setting the RelativeLayout's visibiltiy in the XML file does not change this. Calling .setVisibility during onCreate to manually make that RelativeLayout visible works, but feels wrong. Switching between tabs also makes the RelativeLayout visible again. </p>
  
  <p>Am I missing something fundamental? Is it normal to hand-specify tabs as XML children of the FrameLayout?</p>
