【问题描述】：

我正在尝试设置通知，但无法添加我想要的内容：我希望通知带有声音/振动，同时更改通知按钮徽标。

谁能帮我设置通知？我正在尝试，但它不起作用。

下面的代码工作正常：没有错误。显示所有通知，但没有声音/振动。

【问题讨论】：

我重提了这个问题。我希望它更容易理解......

【参考方案1】：

如果您尝试制作的是应用内通知系统，您可以尝试使用RingtoneManager 和Ringtone 类作为自己的铃声：

        // to play sound for your custom notification on its arrival
        Uri notificationToneUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        Ringtone notificationTone = RingtoneManager.getRingtone(this, notificationToneUri);
        notificationTone.play();

        //to stop
        notificationTone.stop();

See this link for vibration

【讨论】：

添加这个以成功从Firebase获取新通知。
