title: android child view ignore parent padding
body: <p>I have many layouts that have different ViewGroup roots (LinearLayouts, RelativeLayouts, etc). These views all work as I expect, but now I am trying to add a top navigation bar. The problem is that the roots can have different paddings, and if I simply include my layout within each of these layouts, the navigation bar is limited in width by the parent's padding. I'd like this navigation bar to ignore the root's left/right/top padding and be completely full width at the very top of the layout. Is there anything I can do within the navigation bar's layout to achieve this, or am I doomed to have to modify all of the existing layouts to accommodate this?</p>
