title: TabHost in ScrollView, scroll to tab when selected
body: <p>I have a TabHost inside a HorizontalScrollView that can sometimes have more than 20 tabs. On every tab activity, I can press a "next" button that instructs the TabHost to move to the next tab. The problem is, I cannot get the Scrollview to scroll to a selected tab if it is off screen. </p>
  
  <p>Could someone tell me how this can be done?</p>
