    Your scrollbar will scale to the width/height of the resource that you specify for android:scrollbarTrackHorizontal and android:scrollbarTrackVertical.

    This seems to be the only way to do it that I can figure out right now, and I’m not going to monkey around with it anymore 😉

    So if you want an 8px wide horizontal track, and a 12px high vertical track. Create a PNG that is 8px wide for the horizontal track. Create a PNG that is 12px high for the horizontal track. Your nine patches for the android:scrollbarThumbHorizontal and android:scrollbarThumbHorizontal will automatically scale inside of these images.

    <item name="android:scrollbarTrackHorizontal">@drawable/png_12px_high</item>
<item name="android:scrollbarTrackVertical">@drawable/png_8px_wide</item>
