HorizontalListView for Xamarin Forms

• Carousel layout
• Column count
• Infinite loading with Paginator component
• Snapping on first or middle element
• Padding and item spacing
• Handles NotifyCollectionChangedAction Add, Remove and Reset actions
• View recycling
• RecyclerView on Android
• UICollectionView on iOS
• This implementation is in fact very close in terms of philosophy and implementation to what will provide the future Xamarin CollectionView.

Grid collection view (ListLayout = Grid)

• Column count (if equal to 1 then you have a classic ListView ;)
• Infinite loading with Paginator component
• Drag and Drop
• Padding and item spacing
• Handles NotifyCollectionChangedAction Add, Remove and Reset actions
• View recycling

TaskLoaderView displays an ActivityLoader while loading

• Handles error with custom messages and icons
• Handles empty states
• Don't show activity loader for refresh scenarios (if data is already shown)
• Handles retry with button
• Pure Xamarin Forms view: no renderers

It's available in 2 Nuget flavors:

• Sharpnado.Presentation.Forms (which include several others components like the increeeedible TaskLoaderView)
• Sharpnado.Forms.HorizontalListView (HorizontalListView only with only TapCommand and MaterialFrame)

IMPORTANT: On platform projects, call SharpnadoInitializer.Initialize() after Xamarin.Forms.Forms.Init() and before LoadApplication(new App()).

Those components are used and tested in the Silly! app: https://github.com/roubachof/Xamarin-Forms-Practices.
