What is Spinner?

Spinner is a view that displays items in a dropdown fashion, allowing user to pick one at a time.

Spinner is an AdapterView. This means that it relies on an Adapter for its data.

Adapters act as the bridge between adapterviews and the underlying data source.

This makes Spinner like other adapterviews decoupled from data source. Hence we can customize the views shown in the spinner without affecting data.

Spinner is a concrete public class residing in the android.widget package.

In this class we will populate spinner with data from a simple Kotlin array. We will also handle the item selection change events thus showing the selected item in a Toast message.
