Expandable Image header with string items

Question

Layout example

I want to achieve something like that shown in the picture without using any external libraries. I have an ArrayList with objects and each of the objects has a String for the image url and an ArrayList for the string data.

For example, an ArrayList Object:

ArrayList<MyObject> object = new ArrayList<>();

is given as a parameter to the recyclerview adapter.

object=[String urlImage,ArrayList<String> data].

How can I achieve this with viewtypes? What is the condition of position or something like that?
