Spinner Example - Android

In this tutorial we will learn how to use Spinner.

Android spinner is like the drop down hidangan with multiple values from which the end user can select only one value.Android spinner is associated with AdapterView. So you need to use one of the adapter classes with spinner.

We will select item from spinner and set it to the TextView
