Question

我希望这个问题只是与模拟器有关，基本上我有一个设置定时器的服务，一旦timertask运行，下面的代码应该执行：

        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。我不拥有一部Android手机所以我猜这意味着它试图加载一些东西。

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

所以我的问题有两个： - 发生了什么，是否未能加载某些内容？ - 关于如何修复它的任何想法，或者是否值得寻找新的通知形式

编辑：我很抱歉，发现问题是你需要拖下通知窗口 - 我很少使用android x）
