It's possible to put a TextView inside of a RadioGroup. But, is it good practice?

Question

What I\'m trying to accomplish: When the user clicks a specific RadioButton, a TextView should appear immediately below the selected RadioButton.

Answer 1

Is putting the TextView inside of the RadioGroup valid (or, good practice)?

RadioGroup is just a LinearLayout that happens to also handle RadioButton exclusion rules (i.e., "there can only be one...checked, that is"). I see no particular problems in having a TextView inside a RadioGroup.
