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
Example:
| //Do something 2 seconds after view loads | |
| - (void)viewDidLoad | |
| { | |
| [super viewDidLoad]; | |
| [NSTimer scheduledTimerWithTimeInterval:2.0 | |
| target:self | |
| selector:@selector(theAction) | |
| userInfo:nil |
| [ | |

| {name: 'American Samoa', code: 'AS'}, | |
