NotificationPreferenceFragment - 默认构造函数已弃用

Question

我的代码是：

@TargetApi(Build.VERSION_CODES.HONEYCOMB)
public static class NotificationPreferenceFragment extends PreferenceFragment {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        addPreferencesFromResource(R.xml.pref_notification);
        setHasOptionsMenu(true);
        bindPreferenceSummaryToValue(findPreference("notifications_new_message_ringtone"));
        Preference notificationPref = findPreference("notifications_new_message");
        notificationPref.setOnPreferenceChangeListener((preference, newValue) -> {
            boolean isNotificationOn = (Boolean) newValue;
            if(preference.getKey().equals("notifications_new_message") && isNotificationOn){
                FirebaseMessaging.getInstance().subscribeToTopic("news");
            }else{
                FirebaseMessaging.getInstance().unsubscribeFromTopic("news");
            }
            return true;
        });

    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        int id = item.getItemId();
        if (id == android.R.id.home) {
            startActivity(new Intent(getActivity(), ActivityPref.class));
            return true;
        }
        return super.onOptionsItemSelected(item);
    }
}

Android Studio 报告 NotificationPreferenceFragment 的默认构造函数已弃用。如何修复已弃用的警告？

Answer 1

使用 AndroidX 首选项库。此库管理用户界面并与存储交互，以便您仅定义用户可以配置的个别设置。

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