For example, our preferences.xml file was added by addPreferencesFromResource (R.xml.preferences). Our preferences.xml file contains such item:

<SwitchPreference android:id="@+id/notification" android:key="@string/pref_notification_key"

android:title="@string/pref_notification_title"

android:summary="@string/pref_notification_summary"

android:defaultValue="@bool/pref_notification_default_value" app:iconSpaceReserved="false"/>

In our Fragment, we can dynamically get current notification preference value in this way:
A . val isNotificationOn = PreferenceManager.getDefaultSharedPreferences (context).getBoolean( context!!.getString(R.string.pref_notification_key), context!!.resources.getBoolean(R.bool.pref_notification_default_value)
)
B . val isNotificationOn = PreferenceManager.getSharedPreferences (context).getBoolean( context!!.getString(R.string.pref_notification_default_value), context!!.getString(R.string.pref_notification_key),
)
C . val isNotificationOn = PreferenceManager.getSharedPreferences (context).getBoolean( context!!.resources.getBoolean(R.bool.pref_notification_default_value), context!!.getString(R.string.pref_notification_key)
)
