Android 设置：如何在 SettingsFragment 中使用 SharedPreferences？

Question

我在正常 Activity 中使用我自己的 SharedPreferences，自定义布局有两个复选框和搜索栏。现在我想用这些设置做一个合适的 SettingsActivity/SettingsFragment 。有没有办法使用我的自定义 SharedPreference 而不是 PreferenceManager 和默认首选项文件？

我自己的喜好：

sharedPreferences = getSharedPreferences(getResources().getString(R.string.settingTimetable), MODE_PRIVATE);

引自此回答：

You have to manipulate the PreferenceManager of the SettingsFragment. This is what it looks like

// Constants
//--------------------------------------------------------------------------
private final static String TAG = SettingsFragment.class.getName();
public final static String SETTINGS_SHARED_PREFERENCES_FILE_NAME = TAG + ".SETTINGS_SHARED_PREFERENCES_FILE_NAME";

// Life-cycle
//--------------------------------------------------------------------------
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Log.d(TAG, "onCreate()");

    // Define the settings file to use by this settings fragment
    getPreferenceManager().setSharedPreferencesName(SETTINGS_SHARED_PREFERENCES_FILE_NAME);

    // Load the preferences from an XML resource
    addPreferencesFromResource(R.xml.preferences);
}

Then you can access this settings file outside of the fragment like this:

SharedPreferences preferences = getActivity().getSharedPreferences(
        SettingsFragment.SETTINGS_SHARED_PREFERENCES_FILE_NAME,
        Context.MODE_PRIVATE);
