Adding menu items to a BlackBerry device application

You can use the Application Menu Item API, in the net.rim.blackberry.api.menuitem package to add menu
items to a BlackBerry® device application. You can use the ApplicationMenuItemRepository class to add or remove
menu items from a BlackBerry device application.

Register a menu item

1. Import the following classes:
• net.rim.blackberry.api.menuitem.ApplicationMenuItemRepository
• net.rim.device.api.ui.MenuItem
2. Create a class that extends the MenuItem class.
ContactsDemoMenuItem contactsDemoMenuItem = new ContactsDemoMenuItem();
3. Invoke ApplicationMenuItemRepository.getInstance to retrieve the BlackBerry® device application
repository.
ApplicationMenuItemRepository repository =
ApplicationMenuItemRepository.getInstance();
4. Create an instance of the class that extends the MenuItem class.
ContactsDemoMenuItem contactsDemoMenuItem = new ContactsDemoMenuItem();
5. Invoke ApplicationMenuItemRepository.addMenuItem() to add the custom menu item to the
BlackBerry device application repository.
repository.addMenuItem
(ApplicationMenuItemRepository.MENUITEM_ADDRESSCARD_VIEW,
contactsDemoMenuItem);
6. Invoke ApplicationMenuItemRepository.addMenuItem(). Use the MENUITEM_MAPS field to add
the menu item to the BlackBerry device application.
repository.addMenuItem(ApplicationMenuItemRepository.MENUITEM_MAPS,
contactsDemoMenuItem);
