How to connect two or more spinners in one Activity?

Question

Android

Good afternoon! Trying to deal with a spinner? I looked at the lessons and one seemed to be able to connect and display the selected in the TextView, but with the second spinner it doesn’t work either. The list is displayed, but I don’t understand how to display the selected in the TextView. Can someone suggest?

Well, you described an adapter for one spinner, but not for another.
