Padding not working with screenratio?

[mikestu]

I have a layout with two sub LinearLayouts. The first is set to ScreenRatio of 0.4f, the second with 0.6f (40%/60% split). For the second one, I need it to have a right padding of 20, but the views inside of it always butt right up against the screen. I also tried putting right padding on the sub controls, but same thing. It seems like padding just doesn't work with this WidthUnits setting, but maybe I'm doing something wrong.
