How to change ExpandableListView options through settings?

Question

Java

How to change the parameters (color, type, font size) of ExpandableListView through settings (preference.xml) ? If possible, an example or a link to a similar question.
PS Not just make a custom ExpandableListView (it's clear how), but change the list using the settings.

I see it like this: in the adapter, when you create an element's view, you look at the settings values ​​and update all views inside the created view.
