You can use this class to realize a simple sectioned RecyclerView.Adapter without changing your code.

The RecyclerView should use a LinearLayoutManager. You can use this code also with the TwoWayView with the ListLayoutManager (https://github.com/lucasr/twoway-view)

This is a porting of the class SimpleSectionedListAdapter provided by Google

A soft-fullscreen prompt for iOS7+

Background

iOS 7.0 and iOS 8 (Beta) do not have support for minimal-ui viewport keyword, nor do they response to window.slideTo(0,1) or support Fullscreen API, which means there is no easy way to tell Mobile Safari to hide address bar/menu without user interaction.

This is a problem for Web App that mimics Native App design, where html/body are commonly set to height: 100%, so browser viewport = available screen estate. There are currently no solution besides adding apple-mobile-web-app-capable meta and ask users to manually Save to Homescreen.

Frustrated by this limit, we present a soft-fullscreen prompt design, which, coupled with proper CSS hack, can achieve soft-fullscreen with relatively small effort from users.
