如何让通知振动手机反应本机博览会

Question

我需要通知来反复振动手机，直到用户执行单击通知等操作。我还没有找到办法让这项工作发挥作用。起初，我试图使用 React Native Expo 的 Vibrate Api 来解决这个问题。但我后来意识到，如果应用程序被终止并且用户没有与通知交互如此处所述，则博览会无法对通知做出反应。唯一的其他方法是为通知设置振动和间隔。但我似乎找不到办法做到这一点。我正在使用 Node js 发送通知，这实际上与 this 相同的代码。这是唯一用于发送消息的格式。没有振动。但在初始页面上，我看到他们添加了振动。我一定是在某个地方弄错了或者迷路了。我想这可以通过某种方式完成，否则就不会有警报应用程序。我怎样才能做到这一点？在我的 Android 手机上，通知甚至根本不会振动，如果我没有此功能，该应用程序将毫无用处。谢谢）：

我后来找到了这个问题的答案。在 andriod 上，您必须创建一个 channel 并在发送通知时包含它。文档中的所有解释。您将能够创建振动模式等等。另外，如果你像我一样在后端发送通知（我使用了nodejs），你仍然可以创建一个通道，但它必须在前端。在 useEffect 中使用此代码：

if (Platform.OS === 'android') {
Notifications.setNotificationChannelAsync('default', {
  name: 'default',
  importance: Notifications.AndroidImportance.MAX,
  vibrationPattern: [0, 250, 250, 250],
  lightColor: '#FF231F7C',
});

}

您可以将“默认”替换为您想要调用通知通道的任何名称。我还没有找到如何在 ios 上执行此操作。如果我这样做，我会更新。希望我不会忘记）：

您也可以帮助我吗，我有这段代码，我希望手机在收到通知时振动并播放声音，直到用户通过按下即将到来的按钮与通知进行交互。目前还没有响，下面是我的代码

 useEffect(()=> {
    // Add a notification response listener
    const notificationResponseListener = Notifications.addNotificationResponseReceivedListener(
        handleNotificationResponse
    );

    const backgroundSubscription = Notifications.addNotificationReceivedListener(
        handleBackgroundNotification
    );

    Notifications.setNotificationCategoryAsync('acknowledge', [
        {
            buttonTitle: "Coming",
            identifier: "reply",
            options: { opensAppToForeground: true },
        }
    ]);

    if (Platform.OS === 'android') {
        Notifications.setNotificationChannelAsync('alert', {
          name: 'alert',
          importance: Notifications.AndroidImportance.MAX,
          vibrationPattern: [0, 250, 250, 250],
          lightColor: '#FF231F7C',
        });
    }
    
    return () =>{ 
        Notifications.removeNotificationSubscription(notificationResponseListener);
        Notifications.removeNotificationSubscription(backgroundSubscription);
    }
}, [])

// Define a function to handle notification interaction response
const handleNotificationResponse = async (response) => {
    console.log(response)
    //Vibration.cancel();
    await Notifications.dismissAllNotificationsAsync()
};

const handleBackgroundNotification = async (notification) => {
    // Play notification sound
    // Replace with your sound playing logic
    // Example: 
    // SoundPlayer.playSoundFile('notificationSound.mp3', 'mp3');
    // Vibrating continuously
    //Vibration.vibrate([0, 250, 250, 250], true);
};
