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

| * 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 |
