如何在黑莓手機上按計劃時間發送通知

Question

我想在每週的第一天推送諸如「Hello new week」之類的通知。

它每週自動運行。

我已經引用NotificationsDemo通過從Blackberry JDE Plugin導入此項目。

public final class NotificationsDemo extends UiApplication 
{  
    // com.rim.samples.device.notificationsdemo.NOTIFICATIONS_ID_1 
    static final long NOTIFICATIONS_ID_1 = 0xdc5bf2f81374095L; 

    /** 
    * Entry point for application. 
    * @param args Command-line arguments 
    */ 
    public static void main(String[] args) 
    { 
     if(args.length > 0 && args[ 0 ].equals("autostartup")) 
     { 
      NotificationsDemo nd = new NotificationsDemo(); 
      nd.registerNotificationObjects(); 

      // Keep this instance around for rendering 
      // Notification dialogs. 
      nd.enterEventDispatcher(); 
     } 
     else 
     { 
      // Start a new app instance for GUI operations. 
      new NotificationsDemo().showGui(); 
     } 
    } 

    /** 
    * Displays the NotificationDemoScreen. 
    */ 
    private void showGui() 
    { 
     // Create a new instance of the application and make the currently 
     // running thread the application's event dispatch thread. 
     pushScreen(new NotificationsDemoScreen()); 
     enterEventDispatcher(); 
    } 

    /** 
    * Registers this application as the notification manager. 
    */ 
    private void registerNotificationObjects() 
    { 
     // A source is registered to tell the system that our application will 
     // be sending notification events. This will will cause a new user 
     // editable configuration to be added to the Profiles application. 
     NotificationsManager.registerSource(NOTIFICATIONS_ID_1, new Object() 
     { 
      public String toString() 
      { 
       return "Notifications Demo"; 
      } 
     }, NotificationsConstants.IMPORTANT); 

     // Our NotificationsEngineListener implementation will display a dialog 
     // to the user when a deferred event is triggered. 
     NotificationsManager.registerNotificationsEngineListener(NOTIFICATIONS_ID_1, 
       new NotificationsEngineListenerImpl(this));   

     // Our Consequence implementation will invoked whenever an immediate 
     // event occurs.   
     NotificationsManager.registerConsequence(ConsequenceImpl.ID, new ConsequenceImpl()); 
    } 

    /** 
    * The MainScreen class for our UiApplication. 
    */ 
    private static class NotificationsDemoScreen extends MainScreen 
    { 
     private long _eventId; 

     // Constructor 
     private NotificationsDemoScreen() 
     { 
      // Initialize UI components.    
      setTitle("Notifications Demo"); 
      add(new RichTextField("Trigger notification from menu.")); 

      //A menu item to generate immediate and deferred events. 
      MenuItem notifyItem = new MenuItem(new StringProvider("Notify (ID1)"), 0x230010, 0); 
      notifyItem.setCommand(new Command(new CommandHandler() 
      { 
       /** 
       * @see net.rim.device.api.command.CommandHandler#execute(ReadOnlyCommandMetadata, Object) 
       */ 
       public void execute(ReadOnlyCommandMetadata metadata, Object context) 
       { 
        int trigger = NotificationsConstants.MANUAL_TRIGGER; 

        // The timeout parameter is IGNORED unless the TRIGGER 
        // is OUT_OF_HOLSTER_TRIGGER. 
        long timeout = -1; 

        Event e = new Event(NotificationsDemo.NOTIFICATIONS_ID_1, _eventId, 500, timeout, 
          trigger); 
        _eventId++; 
        e.fire(); 
       } 
      })); 
      addMenuItem(notifyItem); 


     } 
    } 
} 

按照我們使用的菜單來打開LED的代碼，但我想沒有菜單運行。我會自動運行。

如何正確設置時間來推送我的通知？

運行的備選入口點，這將運行一個線程，該線程將檢查每星期的開始，然後通過使用此方法顯示一個對話框：

private void showMessage(String data) { 
    UiEngine ui = Ui.getUiEngine(); 
    Screen screen = new Dialog(Dialog.D_OK, data, Dialog.OK, 
    Bitmap.getPredefinedBitmap(Bitmap.EXCLAMATION), 
    Manager.VERTICAL_SCROLL); 
    ui.queueStatus(screen, 1, true); 
}
