TextView dynamically fills the last line of text

Question

I'm not sure this is just the "last line", but we have an application with a TextView with a width of fill_parent, a height of wrap_content. The text is placed there dynamically from Java code. The last line of text simply does not appear, although there is a lot of space in the layout. It is inside a rather deep hierarchy of views, so my hunch is a measure of logic, in which everything went bad, but it's rather complicated. We need to guess how many lines will be in the text and set "android: lines" accordingly to make it work.

Has anyone seen this? In code, see Id 'contentTextView' at the bottom. If I choose android: lines, the last line of text will disappear.
