    It is not clear how to make subcategories - Alex Sh.

    Spinner is not designed for such functionality and with its help it is not worth trying to do. This can be done using ExpandableListView - pavlofff

    So ask "how to make subcategories in a spinner", and not "how to make a spinner." - Enikeyschik
  • Read carefully, it is written after all - "With categories and subcategories" - Alex Sh.

1) Open https://developer.android.com/training/custom-views/create-view.html

2) Look for info about BaseAdapter class, you will need to implement nesting (categories / subcategories)

3) Implement your custom-view, I advise you to inherit via RecyclerView and custom through it, it’s better to use its adapter, I think you will understand, you will understand, there is quite a lot of information about it)
