Setpadding background with the words of a very vague on the stretch I do not stretch ah ah I want to set its margin
And xml can be directly layout_marginLeft activity in such settings Why not? ?

With RadioGroup.LayoutParams (int w, int h) to set the width and height of the RadioButton. The width of your own definition, highly set WRAP_CONTENT.
