Why do you feel it doesn't work?

Ummmm...you're going to need something between those layers. Probably a
ScrollView holds a LinearLayout which holds TextViews.

Yes, you need LayoutParams. More importantly, you need a LinearLayout or
something -- a ScrollView only has one child. So, add your TextViews to
the LinearLayout via addView() with a LinearLayout.LayoutParams object.
However, if you are going to have more than a few dozen comments, you
really really really want to roll back to the ListView approach, as your
proposed UI will take up a fair bit of memory and a fair bit of CPU time
to create. The advantage of ListView is that it can show thousands of
comments using only a handful of TextViews -- your approach would
require thousands of TextViews.
