Subheaders are list tiles that delineate sections of a list or grid list.
Tile height: 48dp
Subheader font: Roboto Medium 14sp
Subheader color can either be the secondary grey text value (54% black) or the primary color of the app.
In long lists of complex information, consider using colored subheaders to delineate content. Android settings contain an example of how color can be used on subheaders.
A subheader should be left-aligned with an avatar/icon in a list, unless there is a promoted action in that space.
If there is a floating action button left-aligned with the avatar/icon in a list, align the subheader with the text content.
