I need to have a custom view in Xamarin.Forms. I need the header to have button in the middle of it, not a toolbar button on the side. The page also needs to change between content pages. Currently I am trying to get the CarouselPage to work since it has the ability to load content pages whereas the CarouselView does not. Also, I cannot use the latest version of Xamarin.Forms (2.5.x) because I must support Android 6 (Marshmallow), so I'm stuck with 22.214.171.1242. I have looked at many custom alternatives, but they all require Android 7 or higher which will not work, also, sometimes they say they'll support a lower version of Android, but something they reference requires a higher version.
Any thoughts on how to accomplish this task?
