John,
You can do this with LinearLayout and layout_weight attribute that it
supports:
<LinearLayout layout_height=fill_parent orientation=vertical>
<View
layout_height="0dp"
layout_weight="20"/>
<TextView
layout_height="0dp"
layout_weight="80"/>
</LinearLayout>
The top view acts as a spacer, taking up 20% of the screen height, and
the TextView starts below that.

Yes, but you'll have to do it at runtime as there is not a way to do
proportional layout as you describe in xml. To prevent a visible
transition from the xml size to the correct size, you'll probably want
to extend LinearLayout and override its onLayout(). You'll want to
layout your child textview within that and you'll want to use
getHeight() to get the height of the LinearLayout at runtime. I'd
suggest looking through the code of ListView or RelativeLayout to see
how children are measured and layout.
The other option would be to do this after everything is inflated. You
can override onFinishInflate of the LinearLayout and then adjust the
height of the TextView from there. You'll need to invalidate the
TextView after adjusting it's height.

Is there a way to position text within a linear layout such that the
position of the text is proportional to the height, rather than a
fixed distance. For example, I would like the text to be displayed
down from the top a distance equal to 20% of the height of the view.
Thanks.
