Strictly speaking, you are correct, of course. But since the OP said '"layout_width"', not 'layout_width', I assumed he was really thinking about the actual numeric value the width takes, rather than the XML attribute "layout_width". But I did not preserve this distinction in my own writing, so I wrote the wrong thing. Not to mention it was a dubious assumption to begin with, though it did make sense out of his asking for it to be set programmatically, while in his sample XML he was already setting it explicitly.
Of course the real XML attribute "layout_width" is set by the user and used by the layout manager. But this raises a natural question, one I am sure has occurred to many others learning Android: what were they thinking when they named this parameter "layout_width"? Doesn't the very name naturally suggest a numeric value measuring the width, rather than rule for deriving that value from elsewhere?
