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);
