问题 I'm using a very helpful example here to show a RecyclerView and a GridLayoutManager to show a grid with a header. It looks pretty good, but my graphic designer wants the header item to take up the full width of the RecyclerView. Right now there is padding. When I set up the GridLayoutManager I add in padding (which I still want for the other grid items): [it's using Xamarin C#] var numColumns = myListView.MeasuredWidth / tileSizeMax; myGridView.SetPadding(tilePadding, tilePadding,
