Android Custom Scrollbar Icon
<p>I would like to know the exact steps to set the icon that appears when rapidly scrolling on a list view.  This appears as a silver icon with three lines through it.  Not certain what the name of this is. I think it might be called the thumb.  Please post a detailed response that shows the exact steps to replace this with my own image.  Also where might I find in the sdk the little silver icon so I can size mine correctly or indicate the dimensions of it.</p>
