如何在PreferenceFragment之外修改Androidx偏好数据？

import android.content.Context;
import android.content.SharedPreferences;
import androidx.preference.PreferenceManager;

public class MyPreferenceManager {
    private SharedPreferences sharedPreferences;
    private SharedPreferences.Editor editor;

    public MyPreferenceManager(Context context) {
        sharedPreferences = PreferenceManager.getDefaultSharedPreferences(context);
        editor = sharedPreferences.edit();
    }

    public void saveData(String key, String value) {
        editor.putString(key, value);
        editor.apply();
    }

    public String getData(String key, String defaultValue) {
        return sharedPreferences.getString(key, defaultValue);
    }

    // 其他操作方法...

}
