What is the name of this control in android?

Question

I was wondering what the name of this control is in android studio and where I can find and use it? (The one that is opened and has all those selectable options.) first I thought it's Expandable List View Item but I don't think it is, unless it's customized or something. Thank you (image credits: Converter app by Asif Chowdhury)

Answer 1

Spinners provide a quick way to select one value from a set. In the default state, a spinner shows its currently selected value. Touching the spinner displays a dropdown menu with all other available values, from which the user can select a new one. You can visit here for demo project (Static list data) android-spinner-dropdown-example . And Android Spinner (DropDown List) Example

Answer 2

This is a spinner control.

The page I linked also contains some examples of how to use one.
