安卓开发 : How to make a custom status bar Notification?

Question

今天我试了又试，只是为了获得带有 2 个按钮和一个 TextView 的自定义消息。我已经得到 XML 了。但是我尝试使用的代码只是给我 Force Close

RemoteViews contentView = new RemoteViews(getPackageName(), R.layout.main);
        contentView.setImageViewResource(R.id.Button01, R.drawable.icon);
        contentView.setTextViewText(R.id.Button01, "Hello, this message is in a custom expanded view");

Intent notificationIntent = new Intent(this, main.class);
        PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);

我很迷茫所以请不要把我送到http://developer.android.com/guide/topics/ui/notifiers/notifications.html我试过了。

如果有人能从一开始就告诉我，我会非常高兴，因为我一整天都在尝试这个，真的很感激一个好的答案!

谢谢!

        final int CUSTOM_VIEW_ID = 1;
        mNotificationManager.notify(CUSTOM_VIEW_ID, notification);

    }
}

由于您发布了错误消息，此行会告诉您自定义通知未成功的原因:

Caused by: android.view.InflateException: Binary XML file line #1: Class not allowed to be inflated android.widget.HorizontalScrollView

移除 Horizo​​ntalScrollView 并使用简单的 TextViews/ImageViews 进行测试。
