seekbar

In a color picker, I have 3 SeekBars for Hue, Saturation, and Value. Calling setProgressDrawable on these SeekBars only works once -- at initialization from onCreate. When the user updates the Hue SeekBar, I want to call setProgressDrawable for the Saturation and Value SeekBars, to show the user their color choices for the new Hue.

But all calls to setProgressDrawable (after the initial ones from onCreate) cause the SeekBar to be blanked.

How can I update the background gradient of my SeekBars based upon user input?

Thanks! Chuck
