ProgressBar under ActionBar, like the last GMail app update [closed]

Question

i would like advices to reproduce the last refresh we can find in the last gmail update under the bar action. Thank you for support.

I guess, i have to use onScroll handler on a ListView via

public void onScroll(AbsListView absListView, int firstVisible, int visibleCount, int totalCount)

and calculating a ratio to detect top overscroll ?

But how to reproduce the same refresh animation (Dotted line, Repeat on x-axis) ?

Here some screenshots.
