title: Android pull to refresh with ScrollView control
body: <p>I am using a ScrollView to display a list of items that are inflated on runtime. Like a feed of updates for the user. 
  While thinking about the options i got to let the user update the view with new notifications I thought about the pull to refresh feature in the twitter app.</p>
  
  <p>Anyone got any idea how and if can it be implemented with a ScrollView ? </p>
  
  <p>Saw there are some implementations for that using ListView but I don't like the idea of changing all of my platform to gain this refresh effect.</p>
