Android 在状态栏添加图标的函数

   private void showNotification() {
        // 创建一个NotificationManager的引用
        NotificationManager notificationManager = (NotificationManager)
            AutoFile.this.getSystemService(android.content.Context.NOTIFICATION_SERVICE);
       
        // 定义Notification的各种属性
        Notification notification = new Notification(R.drawable.dvd,
                "天籁之音播放器", System.currentTimeMillis());
        notification.flags |= Notification.FLAG_ONGOING_EVENT; // 将此通知放到通知栏的"Ongoing"即"正在运行"组中
        notification.flags |= Notification.FLAG_NO_CLEAR; // 表明在点击了通知栏中的"清除通知"后，此通知不清除，经常与FLAG_ONGOING_EVENT一起使用
        notification.flags |= Notification.FLAG_SHOW_LIGHTS;
        notification.defaults = Notification.DEFAULT_LIGHTS;
        notification.ledARGB = Color.BLUE;
        notification.ledOnMS = 5000;
               
        // 设置通知的事件消息
        CharSequence contentTitle = "天籁之音正在播放……"; // 通知栏标题
        CharSequence contentText = "ameyume"; // 通知栏内容
        Intent notificationIntent = new Intent(AutoFile.this, MyPlayerService.class); // 点击该通知后要跳转的Activity
        PendingIntent contentItent = PendingIntent.getActivity(AutoFile.this, 0,
                notificationIntent, 0);
        notification.setLatestEventInfo(AutoFile.this, contentTitle, contentText,
                contentItent);

        // 把Notification传递给NotificationManager
        notificationManager.notify(0, notification);
    }

要删除图标，用以下代码：

            // 启动后删除之前我们定义的通知
            NotificationManager notificationManager = (NotificationManager) this
                    .getSystemService(NOTIFICATION_SERVICE);
            notificationManager.cancel(0);
