希望这对你有所帮助:)

如果你想存储你从响应中得到的整个对象，它可以通过这样做来实现，

首先，在util类中创建一个将JSON转换为字符串的方法，如下所示。

 public static <T> T fromJson(String jsonString, Class<T> theClass) {
    return new Gson().fromJson(jsonString, theClass);
}

然后在共享偏好类中执行如下操作，

 public void storeLoginResponse(yourResponseClass objName) {

    String loginJSON = UtilClass.toJson(customer);
    if (!TextUtils.isEmpty(customerJSON)) {
        editor.putString(AppConst.PREF_CUSTOMER, customerJSON);
        editor.commit();
    }
}

然后为getPreferences创建一个方法

public Customer getCustomerDetails() {
    String customerDetail = pref.getString(AppConst.PREF_CUSTOMER, null);
    if (!TextUtils.isEmpty(customerDetail)) {
        return GSONConverter.fromJson(customerDetail, Customer.class);
    } else {
        return new Customer();
    }
}

然后只是调用第一个方法时，你得到的响应和 其次，当你需要从分享偏好中获取数据时

String token = SharedPrefHelper.get().getCustomerDetails().getAccessToken();

这是所有。

希望对你有所帮助。

快乐的编码();

要添加到@MuhammadAamirALi的答案，您可以使用Gson保存和检索对象列表

保存用户定义对象的列表到SharedPreferences

public static final String KEY_CONNECTIONS = "KEY_CONNECTIONS";
SharedPreferences.Editor editor = getPreferences(MODE_PRIVATE).edit();

User entity = new User();
// ... set entity fields

List<Connection> connections = entity.getConnections();
// convert java object to JSON format,
// and returned as JSON formatted string
String connectionsJSONString = new Gson().toJson(connections);
editor.putString(KEY_CONNECTIONS, connectionsJSONString);
editor.commit();

从SharedPreferences获取用户定义对象的列表

String connectionsJSONString = getPreferences(MODE_PRIVATE).getString(KEY_CONNECTIONS, null);
Type type = new TypeToken < List < Connection >> () {}.getType();
List < Connection > connections = new Gson().fromJson(connectionsJSONString, type);

关于这个问题有很多很好的答案，穆罕穆德·阿米尔·阿里和穆哈默德·埃尔-班纳在Kotlin使用通用方法实现了答案。

为了节省

fun storeObjectInSharedPref(dataObject: Any, prefName: String): Boolean{
    val dataObjectInJson = Gson().toJson(dataObject)
    prefsEditor.putString(prefName, dataObjectInJson)
    return prefsEditor.commit()
}

检索

fun <T> retrieveStoredObject(prefName: String, baseClass: Class<T>): T?{
    val dataObject: String? = preferences.getString(prefName, "")
    return Gson().fromJson(dataObject, baseClass)
}

要了解Kotlin中的泛型，请访问这里

如果你的对象很复杂，我建议序列化/XML/JSON，并将这些内容保存到SD卡。你可以在这里找到关于如何保存到外部存储的其他信息: http://developer.android.com/guide/topics/data/data-storage.html#filesExternal

有两个文件解决了共享首选项的所有问题

1)AppPersistence.java

    public class AppPersistence {
    public enum keys {
        USER_NAME, USER_ID, USER_NUMBER, USER_EMAIL, USER_ADDRESS, CITY, USER_IMAGE,
        DOB, MRG_Anniversary, COMPANY, USER_TYPE, support_phone
    }

    private static AppPersistence mAppPersistance;
    private SharedPreferences sharedPreferences;

    public static AppPersistence start(Context context) {
        if (mAppPersistance == null) {
            mAppPersistance = new AppPersistence(context);
        }
        return mAppPersistance;
    }

    private AppPersistence(Context context) {
        sharedPreferences = context.getSharedPreferences(context.getString(R.string.prefrence_file_name),
                Context.MODE_PRIVATE);
    }

    public Object get(Enum key) {
        Map<String, ?> all = sharedPreferences.getAll();
        return all.get(key.toString());
    }

    void save(Enum key, Object val) {
        SharedPreferences.Editor editor = sharedPreferences.edit();
        if (val instanceof Integer) {
            editor.putInt(key.toString(), (Integer) val);
        } else if (val instanceof String) {
            editor.putString(key.toString(), String.valueOf(val));
        } else if (val instanceof Float) {
            editor.putFloat(key.toString(), (Float) val);
        } else if (val instanceof Long) {
            editor.putLong(key.toString(), (Long) val);
        } else if (val instanceof Boolean) {
            editor.putBoolean(key.toString(), (Boolean) val);
        }
        editor.apply();
    }

    void remove(Enum key) {
        SharedPreferences.Editor editor = sharedPreferences.edit();
        editor.remove(key.toString());
        editor.apply();
    }

    public void removeAll() {
        SharedPreferences.Editor editor = sharedPreferences.edit();
        editor.clear();
        editor.apply();
    }
}

2)AppPreference.java

public static void setPreference(Context context, Enum Name, String Value) {
        AppPersistence.start(context).save(Name, Value);
    }

    public static String getPreference(Context context, Enum Name) {
        return (String) AppPersistence.start(context).get(Name);
    }

    public static void removePreference(Context context, Enum Name) {
        AppPersistence.start(context).remove(Name);
    }
}

现在你可以保存，删除或者获取，

保存

AppPreference.setPreference(context, AppPersistence.keys.USER_ID, userID);

删除

AppPreference.removePreference(context, AppPersistence.keys.USER_ID);

-get

 AppPreference.getPreference(context, AppPersistence.keys.USER_ID);
