android实现状态栏添加图标的函数实例

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); } 

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