코드에서 계층 구조 빌드

코드에서 계층 구조 빌드 Android Jetpack의 구성요소.

아래 예와 같이 onCreatePreferences()에 프로그래밍 방식으로 계층 구조를 만들 수 있습니다.

Kotlin

    override fun onCreatePreferences(savedInstanceState: Bundle?, rootKey: String?) {
        val context = preferenceManager.context
        val screen = preferenceManager.createPreferenceScreen(context)

        val notificationPreference = SwitchPreferenceCompat(context)
        notificationPreference.key = "notifications"
        notificationPreference.title = "Enable message notifications"

        val feedbackPreference = Preference(context)
        feedbackPreference.key = "feedback"
        feedbackPreference.title = "Send feedback"
        feedbackPreference.summary = "Report technical issues or suggest new features"

        screen.addPreference(notificationPreference)
        screen.addPreference(feedbackPreference)

        preferenceScreen = screen
    }
    

자바

    @Override
    public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
        Context context = getPreferenceManager().getContext();
        PreferenceScreen screen = getPreferenceManager().createPreferenceScreen(context);

        SwitchPreferenceCompat notificationPreference = new SwitchPreferenceCompat(context);
        notificationPreference.setKey("notifications");
        notificationPreference.setTitle("Enable message notifications");

        Preference feedbackPreference = new Preference(context);
        feedbackPreference.setKey("feedback");
        feedbackPreference.setTitle("Send feedback");
        feedbackPreference.setSummary("Report technical issues or suggest new features");

        screen.addPreference(notificationPreference);
        screen.addPreference(feedbackPreference);

        setPreferenceScreen(screen);
    }
    

아래와 같이 PreferenceCategory를 추가하는 것은 비슷합니다. 하위 요소를 루트 PreferenceScreen이 아닌 PreferenceCategory에 추가해야 합니다.

Kotlin

    override fun onCreatePreferences(savedInstanceState: Bundle?, rootKey: String?) {
        val context = preferenceManager.context
        val screen = preferenceManager.createPreferenceScreen(context)

        val notificationPreference = SwitchPreferenceCompat(context)
        notificationPreference.key = "notifications"
        notificationPreference.title = "Enable message notifications"

        val notificationCategory = PreferenceCategory(context)
        notificationCategory.key = "notifications_category"
        notificationCategory.title = "Notifications"
        screen.addPreference(notificationCategory)
        notificationCategory.addPreference(notificationPreference)

        val feedbackPreference = Preference(context)
        feedbackPreference.key = "feedback"
        feedbackPreference.title = "Send feedback"
        feedbackPreference.summary = "Report technical issues or suggest new features"

        val helpCategory = PreferenceCategory(context)
        helpCategory.key = "help"
        helpCategory.title = "Help"
        screen.addPreference(helpCategory)
        helpCategory.addPreference(feedbackPreference)

        preferenceScreen = screen
    }
    

자바

    @Override
    public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
        Context context = getPreferenceManager().getContext();
        PreferenceScreen screen = getPreferenceManager().createPreferenceScreen(context);

        SwitchPreferenceCompat notificationPreference = new SwitchPreferenceCompat(context);
        notificationPreference.setKey("notifications");
        notificationPreference.setTitle("Enable message notifications");

        PreferenceCategory notificationCategory = new PreferenceCategory(context);
        notificationCategory.setKey("notifications_category");
        notificationCategory.setTitle("Notifications");
        screen.addPreference(notificationCategory);
        notificationCategory.addPreference(notificationPreference);

        Preference feedbackPreference = new Preference(context);
        feedbackPreference.setKey("feedback");
        feedbackPreference.setTitle("Send feedback");
        feedbackPreference.setSummary("Report technical issues or suggest new features");

        PreferenceCategory helpCategory = new PreferenceCategory(context);
        helpCategory.setKey("help");
        helpCategory.setTitle("Help");
        screen.addPreference(helpCategory);
        helpCategory.addPreference(feedbackPreference);

        setPreferenceScreen(screen);
    }
