本文实例讲述了android实现状态栏添加图标的函数。分享给大家供大家参考。具体如下:
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ActivityPendingIntent contentItent = PendingIntent.getActivity(AutoFile.this, 0, notificationIntent, 0);notification.setLatestEventInfo(AutoFile.this, contentTitle, contentText, contentItent);// 把Notification传递给NotificationManagernotificationManager.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);
希望本文所述对大家的Android程序设计有所帮助。
