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:

nlohmann

def remove_empty_elements(d):
    """recursively remove empty lists, empty dicts, or None elements from a dictionary"""

    def empty(x):
        return x is None or x == {} or x == []

    if not isinstance(d, (dict, list)):
        return d
    elif isinstance(d, list):
        return [v for v in (remove_empty_elements(v) for v in d) if not empty(v)]
