我希望这个问题只是与模拟器有关，基本上我有一个设置计时器的服务，只要 timertask 运行以下代码应该执行：

        String ns = Context.NOTIFICATION_SERVICE;
        NotificationManager mNotificationManager = (NotificationManager)getSystemService(ns);

        int icon = R.drawable.androidapplogo;
        CharSequence tickerText = "Ticker Text";
        long when = System.currentTimeMillis();

        Notification notification = new Notification(icon, tickerText, when);
        Context context = getApplicationContext();
        CharSequence contentTitle = "My Notification";
        CharSequence contentText = "Hello World!";          

        //Do i need this?
        Intent notificationIntent = new Intent();
        PendingIntent contentIntent = PendingIntent.getActivity(ctx, 0, notificationIntent, 0);         

        notification.setLatestEventInfo(context, contentTitle, contentText, null);
        mNotificationManager.notify(1, notification);

我遇到的问题是，当通知被调用时，它会出现在状态栏中，但是当我点击图标时，它只有一个蓝色圆圈。我没有安卓手机，所以我猜这意味着它试图加载一些东西。

顺便说一句，我几乎从这里提升了代码：http: //developer.android.com/guide/topics/ui/notifiers/notifications.html

所以我的问题有两个方面： - 发生了什么，是否无法加载某些内容？- 关于如何修复它的任何想法，或者是否值得寻找一种新的通知形式

编辑：对不起，伙计们，发现问题是您需要向下拖动通知窗口-我很少使用 android x)
