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。 } 全部Service代码
