코드에 계층 구조 만들기 Android Jetpack의 구성요소

다음에서 프로그래매틱 방식으로 계층 구조를 만들 수 있습니다. onCreatePreferences() 다음 예는 동일한 인코더-디코더 아키텍처를 기본 설정 화면은 개요 페이지를 참조하세요. 받는사람 화면을 프로그래밍 방식으로 만들고, 각 설정을 만들고, 관련된 설정을 속성을 가져온 다음 환경설정 화면에 추가합니다.

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
}
 
@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);
}

PreferenceCategory: 있습니다. 다음 예는 프로그래매틱 방식으로 기본 설정 화면은 설정을 구성합니다. 하위 요소는 루트가 아닌 PreferenceCategory에 추가됩니다. PreferenceScreen
