What layout do spinners implement by default?

Question

I have a layout with multiple spinners. Some have adapters while others get their contents from string arrays. The ones with the adapters implement the simple_list_item_1 layout, but this causes a different look than the other spinners and leads to formatting issues on the page. How does one find out, or does anyone know what layout a spinner uses by default?

Answer 1

A spinner's layout is dependent on the layout passed to it's adapter.

It looks like simple_list_item_1 is a simple TextView with padding:
