7. Android Widgets > Creating a Collection Widget
Creating a Collection Widget
Android 3.0 introduced a new type of widget that can display a collection of data provided by a remote data source such as a ContentProvider. The widget itself displays this data in a list, grid, stack, or picture frame. Creating one of these widgets is exactly like creating a standard widget but requires a new RemoteViewsService and RemoteViewsFactory to supply the collection data.
Creating the Layout
The layout for a collection widget should contain a collection view, as well as a TextView that displays when the collection is empty. The collection view can be one of the following:
• ListView. A vertically scrolling list of items.
• GridView. A vertically scrolling grid of items.
• StackView. A stack of cards the user can flip through.
