使用开关启用和禁用推送通知 [英] push notification enable and disable by using switch

问题描述

我正在使用 firebase 推送通知 (FCM).我想使用切换按钮启用和禁用通知.

I'm using firebase push notification(FCM).. and I want to enable and disable notifications using a switch button.

为此，我共享了启用和禁用通知的首选项，但似乎我的逻辑根本不起作用.

For that I have shared preferences to enable and disable notifications but it seems my logic is not at all working.

开关是打开还是关闭没有任何区别.我仍在接收通知.

It doesn't make any difference if the switch is turn on or off. I am still receiving notifications.

我需要帮助，谢谢.

    simpleSwitch.setChecked(sharedPreferences.getBoolean("SWITCH_PARTIDOS_STATE", false))

    simpleSwitch.setOnCheckedChangeListener(CompoundButton.OnCheckedChangeListener { buttonView, isChecked ->
        sharedPreferences.edit().putBoolean("SWITCH_PARTIDOS_STATE", isChecked).commit()
        if (isChecked) {
           // FirebaseMessaging.getInstance().subscribeToTopic("Partidos")

                Toast.LENGTH_LONG).show()
        } else {
          //  FirebaseMessaging.getInstance().unsubscribeFromTopic("Partidos")
            Toast.makeText(applicationContext, "Desactivado Correctamente",

        PreferenceHelper.prefernceHelperInstace.setBoolean(applicationContext, Constants.MessageNotificationKeys.ENABLE_NOTIFICATION, true);

使用topic的方法(需要帮助):---------

using the method of topic(need help ):---------

     val sharedPreferences = getSharedPreferences("myname", MODE_PRIVATE)

    simpleSwitch.setChecked(sharedPreferences.getBoolean("SWITCH_STATE", false))

    simpleSwitch.setOnCheckedChangeListener(CompoundButton.OnCheckedChangeListener { buttonView, isChecked ->
        sharedPreferences.edit().putBoolean("SWITCH_STATE", isChecked).commit()
        if (isChecked) {
            // FirebaseMessaging.getInstance().subscribeToTopic("Partidos")
  FirebaseMessaging.getInstance().subscribeToTopic("main_notification");
         

            Toast.makeText(applicationContext, "enabled notification",
                Toast.LENGTH_LONG).show()
        }
        else {
            FirebaseMessaging.getInstance().unsubscribeFromTopic("main_notification");
            Toast.makeText(applicationContext, "disabled notification",
                Toast.LENGTH_LONG).show()
        }

    })

这段代码的问题是它首先不起作用(它在关闭时收到通知)在打开关闭(切换按钮)后它起作用(当打开时收到通知而关闭时没有收到).

The problem of this code is it doesn't worked at first(it receives notification at on off both) after switching on off (switching buttons) it works(when on receives notification and off doesn't receive).

推荐答案

FirebaseMessagingService 即使应用不在前台，也会在后台运行，因此您将无法使用 <代码>应用程序上下文.您应该使用主题消息传递 - https://firebase.google.com/docs/cloud-messaging/android/topic-messaging

FirebaseMessagingService runs in the background even when the app's not in the foreground so you won't be able to get the preferences using applicationContext. You should use Topic messaging - https://firebase.google.com/docs/cloud-messaging/android/topic-messaging

在您的交换机的更改侦听器中使用它:

Use this in your switch's change listener:

启用推送通知 -

FirebaseMessaging.getInstance().subscribeToTopic("your_topic");

禁用推送通知 -

FirebaseMessaging.getInstance().unsubscribeFromTopic("your_topic");

通过这种方式，您将通知 Firebase 您不想收到有关特定主题的通知.

This way you will notify Firebase that you don't want to get notifications about a particular topic.
