Populating the spinner with database data

So which method would be better?

Hi Carlos,

The only option I consider valid and safe would be to manage the lists as dictionaries with unique keys.

If I can, once I finish work, I’ll create a guide since it could be useful for everyone.
However, it’s necessary to use either Recycler List or Dynamic Component so that the clicked component can be assigned the unique key as an ID, while visually using a label with the item’s name.

I hope I explained myself clearly enough
There’s a lot written, but in the end, the functionality is very simple.

Ragazzo, sei un genio!!!
I’ll read it very carefully later. I’m studying for the Google Cloud Digital Leader Certification and I need to concentrate a lot on that. If this post expires, I can reopen it if I have any questions.

Anyway, thank you so much for everything!

Best wishes for your certification and happy studying.
