android实现状态栏添加图标的函数实例

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);

希望本文所述对大家的Android程序设计有所帮助。
