Android 如何将SharedPreferes的价值转换为FirebaseMessagingService？

我想使用SharedReferences设计推送通知的自定义关闭/打开

如何从FirebaseMessagingService中的SharedReferences中获取值（true或false）

我的两个选项都不起作用：

直接从SharedPreferences获取值，但getPreferences在FMS中不起作用

将值从活动传递给FirebaseMessagingService。但是怎么做呢

也许有第三种选择会奏效。请帮帮我

下面是我的FirebaseMessagingService代码文件

class MyFirebaseMessagingService : FirebaseMessagingService() {

private val CURRENT_PUSH = "currentPush"
private var sPref: SharedPreferences? = null

override fun onMessageReceived(remoteMessage: RemoteMessage?) {
    super.onMessageReceived(remoteMessage)

        if (remoteMessage!!.data != null)
            sendNotification(remoteMessage)
}

private fun sendNotification(remoteMessage: RemoteMessage) {
    val data = remoteMessage.data

    val title = data["title"]
    val content = data["content"]

    val notificationManager = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
    val NOTIFICATION_CHANNEL_ID = "1234"

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        @SuppressLint("WrongConstant") val notificationChannel = NotificationChannel(NOTIFICATION_CHANNEL_ID,
                "SA Notification",
                NotificationManager.IMPORTANCE_MAX)

        notificationChannel.description = "SA channel notification"
        notificationChannel.enableLights(true)
        notificationChannel.lightColor = Color.RED
        notificationChannel.vibrationPattern = longArrayOf(0, 1000, 500, 1000)
        notificationChannel.enableVibration(true)

        notificationManager.createNotificationChannel(notificationChannel)
    }


    val notificationBuilder = NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID)

    notificationBuilder.setAutoCancel(true)
            .setDefaults(Notification.DEFAULT_ALL)
            .setWhen(System.currentTimeMillis())
            .setSmallIcon(R.drawable.sa_launcher)
            .setContentTitle(title)
            .setContentText(content)
            .setContentInfo("Breaking")

    notificationManager.notify(1, notificationBuilder.build())
}

override fun onNewToken(s: String?) {
    Log.i(C.T, "NEW_TOKEN" + s!!)
}

private fun loadCurrentPushNotification(): Boolean { //to read the status push notification from SharedPreferences
    sPref = getPreferences(Context.MODE_PRIVATE) //this is not working
    return sPref!!.getBoolean(CURRENT_PUSH, true)
}
}

不确定什么

上下文。模式\u PRIVATE

，因此您可能必须用应用程序上下文替换

然后

---

它开始起作用，但并不正确。结果显示在getBoolean中指定为默认值的值（CURRENT_PUSH，true）。已忽略SharedReferences中的正确值。很抱歉，昨晚太晚了，如果workfirst参数需要StringEdit，则已编辑的答案需要StringEdit，您只需更改为

GetSharedReferences（）

？很遗憾，此选项不起作用。GetSharedReferences需要两个参数（字符串名，int模式）。那里的名称和模式是什么？

 sPref = getSharedPreferences(CONTEXT)

 return sPref!!.getBoolean(CURRENT_PUSH, true)
