body: <p>How do I add scrollbars to a view in Android?</p>
  
  <p>I tried by adding <code>android:scrollbars:"vertical"</code> to the <code>LinearLayout</code> in my layout XML file  but it is not working. </p>
  
  <p>I thought scrollbars were drawn by default in Android but it does not seem that way. It seems we have to draw it ourselves - how do I do this?</p>
