Android XML layout set attributes of children?

Question

This is a quick, probably yes/no question, but I'm trying to pretty up my xml and I'm wondering if there is a way to have a parent layout override the children's layout_width property? that way I can omit layout_width from every child node, for fewer lines of code?

Is the parent your own custom class? If so, the answer is "yes", as TableRow does this. — CommonsWare

@CommonsWare That's interesting, I thought it was a 'fixed' thing that every xml element should have layout_width & layout_height. Is TableRow an exception to this case, or are they other such views as well? — Chrisvin Jem

@ChrisvinJem: TableLayout and TableRow are the only ones that I know of that set a default layout_width and layout_height for its children. It wasn't a widespread technique, and as a result I don't know the details of how those classes are doing what they are doing. But, the source is available, and so a sufficiently motivated person could figure out the mechanism. — CommonsWare
