Fill in Android SeekBar

Question

I am trying to make an hourglass android SeekBar. When I try to get it to completely fill in the SeekBar, it only fills in the center. How can I make the Vertical SeekBar's slider wider?

What it looks like currently:

What I want it to look like:

Please note that the INSIDE of the hourglass is transparent and the OUTSIDE is grey. I've been trying to find a way to have the image placed over the SeekBar so it will fill it in. The first image is what it looks like with the image as a background for the SeekBar.

For anyone wanting to do this, you can't. I ended up making 25 images for the progress bar's 25 states. These images were updated in an ImageView behind the progress bar. I made the ProgressBar transparent so it would not show up over the image. When the progress changed, I updated the image.
