【Android】利用服务Service创建标题栏通知

创建标题栏通知的核心代码

	public void CreateInform() {
		//定义一个PendingIntent，当用户点击通知时，跳转到某个Activity(也可以发送广播等)
		Intent intent = new Intent(context,MainActivity.class);
		PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);

		//创建一个通知
		Notification notification = new Notification(R.drawable.icon, "巴拉巴拉~~", System.currentTimeMillis());
		notification.setLatestEventInfo(context, "点击查看", "点击查看详细内容", pendingIntent);

		//用NotificationManager的notify方法通知用户生成标题栏消息通知
		NotificationManager nManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
		nManager.notify(100, notification);//id是应用中通知的唯一标识
		//如果拥有相同id的通知已经被提交而且没有被移除，该方法会用更新的信息来替换之前的通知。
	}

		// TODO Auto-generated method stub
		super.onDestroy();
	}

	@Override
	public IBinder onBind(Intent intent) {
		// TODO Auto-generated method stub
