/**
 * Based on https://gist.github.com/mikelehen/3596a30bd69384624c11#file-generate-pushid-js
 *
 * Fancy ID generator that creates 20-character string identifiers with the following properties:
 *
 * 1. They're based on timestamp so that they sort *after* any existing ids.
 * 2. They contain 72-bits of random data after the timestamp so that IDs won't collide with other clients' IDs.
 * 3. They sort *lexicographically* (so the timestamp is converted to characters that will sort properly).
 * 4. They're monotonically increasing.  Even if you generate more than one in the same timestamp, the
 *    latter ones will sort after the former ones.  We do this by using the previous random bits

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

The RecyclerView has to use a GridLayoutManager.

This is a porting of the class SimpleSectionedListAdapter provided by Google

If you are looking for a sectioned list RecyclerView.Adapter you can take a look here
