title: How to do 'fastScrollEnabled' like ListView in ScrollView?
body: <p>I need fast scroll thumb <strong>in ScrollView</strong> (which we can scroll by dragging the thumb, like in fastScrollEnabled ListView). Problem detail: The list are rows composed with different TypeFace and alignment.</p>
  
  <p>Row 1:<br>
  TextView1 (TypeFace:A &amp; LeftAligned)<br>
  TextView2 (TypeFace:B &amp; RightAligned)<br> </p>
  
  <p>Row 2:<br>
  TextView3 (TypeFace:A &amp; LeftAligned)<br>
  TextView4 (TypeFace:B &amp; RightAligned)<br>
  .<br>
  .<br>
  .</p>
  
  <p>Second requirement: I need to be alerted when the view scrolled, including new scroll position - which is implemented by overriding <code>onScrollChanged</code> method of the ScrollView.</p>
  
  <p>So I use ScrollView cause I though its impossible to implement using ListView.</p>
  
  <p>Suggestion?</p>
