ListView

A ListView is a type of AdapterView that displays a vertical list of scroll-able views and each view is placed one below the other.

setAdaptor() method conjoins an adapter with the list.

Android ListView is a ViewGroup that is used to display the list of items in multiple rows and contains an adapter that automatically inserts the items into the list.

The main purpose of the adapter is to fetch data from an array or database and insert each item that placed into the list for the desired result.

So, it is the main source to pull data from strings.xml file which contains all the required strings in Java or XML files.
