Android 利用服务Service创建标题栏通知

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。  
}
