Thanks Dianne. I was looking for more guidance toward the best practices for handling this so not to deviate from the intentions of your team and consequently do something that would break in future releases or in situations that I didn't expect.
I implemented a quick and dirty fix that allows me to handle this on existing layout managers by overriding onMeasure. Code is posted over on stackoverflow: http://stackoverflow.com/questions/6298827/can-onmeasure-be-skipped-when-adding-a-view-to-a-viewgroup-solved.
