Android开发：如何制作自定义状态栏通知？

标签： android statusbar

我今天尝试过尝试获取带有2个按钮和TextView的自定义消息。 我得到了XML alraight。但我试图使用的代码只给我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);

而且我很丢失所以请不要把我送到http://developer.android.com/guide/topics/ui/notifiers/notifications.html 我试过了。

如果有人可以从开始的时候告诉我，我会非常高兴，因为我整天都在努力地尝试这一点而且真的非常感谢一个好的答案！

谢谢！

        notification.contentView = contentView;

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

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

    }
}

答案 0 :(得分：0)

由于您已发布错误消息，此行告诉您无法使用自定义通知的原因：

  

引起：android.view.InflateException：二进制XML文件行＃1：类不允许膨胀android.widget.Horizo​​ntalScrollView

删除HorizontalScrollView，然后使用简单的TextView s / ImageView进行测试。
