Quite possibly.

Just call addView() with the child View. Note that I have never tried
populating a ScrollView from Java (most people use XML).

Write your own ViewGroup.

Or, don't use widgets at all, and draw on the Canvas, the way 2D games do.

Bear in mind that there is a massive range of screen resolutions
(based on size/density), which is why AbsoluteLayout is deprecated, as
it does not lend itself to creating UIs that work well on everything
from a 3" phone to a 10" tablet to a 42" TV.
