A sample project for displaying a scrollbar with NativeScript-Grid-View
An android view RecyclerView, which is nicely wrapped by a great plugin NativeScript-Grid-View, cannot show a scrollbar programatically in a native way.(for details, see https://stackoverflow.com/a/27298868/5272836)
It is, however, actucally be possible to display a scroll bar with the Label view.
This repository provides the way to do this for reference.
