Why doesn't R.color.white work where Color.WHITE does?
===

I'm trying to set the background of a very simple layout:

      LinearLayout ll = (LinearLayout) findViewById(R.id.simple_layout);

This works:

      ll.setBackgroundColor(Color.WHITE);

But this doesn't:

      ll.setBackgroundColor(R.color.white);

And yes, I verified that `R.color.white` is defined in a colors.xml file under `/res/values`.

What am I missing?
