How to add an array of objects to sharedPreferences?

Question

Java

I have an array that consists of films - instances of the FilmItem class :

private ArrayList<FilmItem> filmItems = new ArrayList<>();

How to save it through sharedPreferences and then read it?

Answer 1

No way.
You can write your own implementation of converting your list to a string and back.
But SharedPreferences is not designed to store large amounts of data, use a database.

Answer 2

serialization to json (so as not to write the converter yourself), store as a string
