![]() ![]() The CustomOnItemSelectedListener() is an interface implementing OnItemSelectedListener. The setOnItemSelectedListener() registers a callback to be invoked when an item in this AdapterView has been selected.

Don’t forget to declare that array in your strings.xml file and specify those elements in that the main activity, declare two Spinners, initialise their views. This is done by the attribute android:entries=” “. Now we need to specify each with the array of items to populate with. In our XML file, we first drag and drop two spinner widgets. To learn how this is done you can refer to my tutorial on Intents and Shared Preferences. If you find this hard then for now just display the user’ s selection in the same activity. To switch between we use Intents and to pass the user selections of these spinners to the next activity we use SharedPreferences. So, here I have an example where users have to select his gender and Android version and click the button which launches a new activity to display the user selections. So here in this Android Series, we learn how to implement these Spinners. The items in the Spinner come from the Adapter associated with this view. Spinner is a view that displays one child at a time and lets the user pick among them. Thus, they avoid blocking your view and using unnecessary screen space. The user can select one of the items and continuous. When the user clicks on that element they drop down like a list.
