title: Custom scrollbar for listview
body: <p>I have a task to create a custom scrollbar for list view and to my knowledge the way you can customize your scrollbar is very limited on android. Is it possible to achieve exact same result like this:
  <img src="https://i.stack.imgur.com/3uOBG.png" alt="enter image description here"></p>
  
  <p>If so, can you point me to a good example, or at least tell me what should I look into?</p>
  
  <p>[EDIT] Also when scrolling, I would like to be able to use the thumb icon.</p>
