For some Views and types of data the code that links them together is provided by an Adapter. Finally there is the code that links the Views to the data. There is data that needs to be displayed in those Views. There are the Views that make up the screens (managed by Activites). Programmers coding with the Android SDK soon come across a familiar pattern when designing the user interface. When entering code in Studio add import statements when prompted by pressing Alt-Enter.) The example code can be changed to meet your own requirements. (This Android loading Spinner tutorial assumes that Android Studio is installed, a basic App can be created and run, and the code in this article can be correctly copied into Android Studio. A Spinner on other platforms is closer to the Android Pickers, which are often seen when setting dates and times on an Android device. The Android Spinner behaves in a similar fashion to what some may call a drop down list. ![]() ![]() Programmers moving to Android from other environments will notice a difference in terminology. ![]() The Spinner View is useful when you want the user to pick an item from a predetermined list, but do not want to take up a lot of screen space (such as using several radio buttons).
