Hi, in this video, I'll demonstrate how to work with Spinner in Android. I'll show you step-by-step, how to do the following:

1. Add a spinner in XML and load the list of items with a string array defined in a string resource file. If the available choices for your spinner are pre-determined it's the best way to do it.
2. Add another spinner in XML and load the items dynamically using ArrayList and ArrayAdapter.
3. Add a normal button and set a click listener on that, when clicked on this button it displays selected values of the two Spinners as a Toast message.
4. Set OnItemSelectedListener on both the Spinners to handle the OnItemSelected event which is triggered when the user selects an item.

Let's get started.

What is Spinner?
Android spinner is used to quickly select one item or value from a list of items or set. It is just a drop-down list seen in other programming languages. For example, Android Spinner is just like a combo box of AWT or Swing. It's very much similar to the HTML select tag. Android spinner is associated with an Adapter. So you need to use one of the Adapter classes with spinner. The values for the spinner can come from any source like Array or ArrayList or SQLite database but must be provided through a SpinnerAdapter, such as an ArrayAdapter or CursorAdapter, etc. You can also create your own custom Adapter by extending ArrayAdapter or BaseAdapter for a more complex design that fits your needs. Android Spinner class is the subclass of AbsSpinner class.
