Xml:

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
    <PreferenceCategory
        android:title="@string/notifications_title"
        android:key="notification_title">
        <android.support.v7.preference.SwitchPreferenceCompat
            android:defaultValue="true"
            android:key="enable_notifications"
            android:summary="@string/enable_notification_summary"
            android:title="@string/notifications_title" />
        <RingtonePreference
            android:key="pref_tone"
            android:title="@string/pref_tone"
            android:showDefault="true"
            android:ringtoneType="notification"
            android:showSilent="true"/>
    </PreferenceCategory>
</PreferenceScreen>

Java class:

    public class SettingsActivity extends AppCompatActivity {

    public static final String KEY_PREF_NOTIFICATION_SWITCH = "enable_notifications";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getSupportFragmentManager().beginTransaction()
                .replace(android.R.id.content, new SettingsFragment())
                .commit();
    }
}

Fragment:

public class SettingsFragment extends PreferenceFragmentCompat {

    @Override
    public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
        setPreferencesFromResource(R.xml.preferences, rootKey);
    }

}

Part of gradle where I add support libraries:

implementation "com.android.support:appcompat-v7:27.1.1"
implementation 'com.android.support:support-v13:27.1.1'
implementation "com.android.support.constraint:constraint-layout:1.1.2"
implementation "com.android.support:recyclerview-v7:27.1.1"
implementation "com.android.support:cardview-v7:27.1.1"
implementation "com.android.support:design:27.1.1"
implementation 'com.android.support:preference-v7:27.1.1'

Part of the strings.xml file that related to SettingsActivity:

<!-- Settings Screen -->
<string name="settings_label">Settings</string>
<string name="notifications_title">Notifications</string>
<string name="enable_notification_summary">Notifications report the end of the sorting when app is minimized</string>
<string name="pref_tone">Notification ringtone</string>

@MRah You mean strings.xml or what? Cause I already post preferences.xml — Maxim Ovchinnikov, Jul 25 '18 at 04:39
Ringtone preference does not exist in the support library. You need to use the framework's version or create your own. Check this similar question https://stackoverflow.com/questions/35692522/how-to-implement-ringtonepreference-in-preferencefragmentcompat — Zain Ali, Jul 25 '18 at 05:00
@ZainAli Thanks a lot. Could you please add an aswer so I can close question? — Maxim Ovchinnikov, Jul 25 '18 at 05:20
