How to enable a "textView" scrollbar scroll with a thumb?

Question

I have a textview that is wrapped around a ScrollView to display a large dump of text. So far, i've played around with enabling the scrollbar with android:scrollbars="vertical, and turning it permanently visible with android:fadeScrollbars="false".

Is there a way to achieve simple thumb scrolling function on a textview? Something similar to this:

Turns out TextView is not an ideal way. I eventually implemented a ListView to make it work as described above.
