问题 Based on what I learned here, I was able to add some "fences" around groupings of related widgets: But, as you can see, the second/lower box is crowding the first radio button text. Which element do I need to modify to add some space?

ConstraintLayout, RadioGroup and two columns of RadioButton

Turns out having a ConstraintLayout as a Root layout, Containing the RadioGroup, doesn't seem to change anything. But maybe I'm wrong. How would you guys achieve having two rows
