For example, our preferences.xml file was added by addPreferencesFromResource(R.xml.preferences). Our preferences.xml file contains such item:
<ListPreference
android:id="@+id/order_by"
android:key="@string/pref_sort_key"
android:title="@string/pref_sort_title"
android:summary="@string/pref_sort_summary"
android:dialogTitle="@string/pref_sort_dialog_title"
android:entries="@array/sort_oder"
android:entryValues="@array/sort_oder_value"
android:defaultValue="@string/pref_default_sort_value"
app:iconSpaceReserved="false" />
In our Fragment, we can dynamically get current notification preference value in this way:

A. val sortBy = PreferenceManager.getDefaultSharedPreferences(context).getString( context!!.getString(R.string.pref_sort_key), context!!.resources.getBoolean(R.bool.pref_default_sort_value) )
B. val sortBy = PreferenceManager.getSharedPreferences(context).getString( context!!.getString(R.string.pref_default_sort_value), context!!.getString(R.string.pref_sort_key), )
C. val sortBy = PreferenceManager.getSharedPreferences(context).getBoolean( context!!.resources.getBoolean(R.bool.pref_default_sort_value), context!!.getString(R.string.pref_sort_key) )
D. val sortBy = PreferenceManager.getDefaultSharedPreferences(context).getString( context!!.getString(R.string.pref_sort_key), context!!.getString(R.string.pref_default_sort_value) )
