title: Android's viewDidLoad and viewDidAppear equivalent
body: <p>Does Android have an equivalent to Cocoa's viewDidLoad and viewDidAppear functions? </p>
  
  <p>If not, then how would I go about performing an action when a View appears? My app is a tabbed application, in which one of the tabs is a list of forum topics. I would like the topic list to be refreshed every time the view appears. Is such a thing possible in Android?</p>
