title: TabHost setCurrentTab only calls oncreate method for Activity in Tab once
body: <p>I'm following the example here:</p>
  
  <p><a href="http://developer.android.com/resources/tutorials/views/hello-tabwidget.html" rel="noreferrer">http://developer.android.com/resources/tutorials/views/hello-tabwidget.html</a></p>
  
  <p>Everything works fine.  The first time I click on each tab, the <code>oncreate</code> method for Activity bound to that particular tab is called.  However, subsequent selections of the tab's do not call this oncreate method.  </p>
  
  <p>I need to be able to execute oncreate (or another method) on the Activity that is bound to each Tab, when that tab is selected.  I know I can use a <code>setOnTabChangedListener</code>, but I am unsure how to get access to the Activity that is bound to the tab, so that I can call the oncreate (or another) method.</p>
