Seekbar slider 'positioner' or 'pad'

[rfresh]

As shown in the image, how can I enlarge the seekbar slider object that you move left and right with your finger? I've sized up the seekbar itself but the 'slider' object remains small. Can this be enlarged too?

Thanks...

I've run into this also. I don't think you can change it. On my device running 2.2 it is small as shown in your image. The same code on ICS or 2.3.4 it is much larger. Seems it is part of the OS system.
