这么多好答案，她是我的2美分

我更喜欢使用内联函数和旧风格的put和get值

object PreferenceHelper {

    private const val PREFERENCES_KEY = "MyLocalPreference"

    private fun getPreference(context: Context): SharedPreferences {
        return context.getSharedPreferences(
            PREFERENCES_KEY,
            Context.MODE_PRIVATE
        )
    }

    fun setBoolean(appContext: Context, key: String?, value: Boolean?) =
        getPreference(appContext).edit().putBoolean(key, value!!).apply()

    fun setInteger(appContext: Context, key: String?, value: Int) =
        getPreference(appContext).edit().putInt(key, value).apply()

    fun setFloat(appContext: Context, key: String?, value: Float) =
        getPreference(appContext).edit().putFloat(key, value).apply()

    fun setString(appContext: Context, key: String?, value: String?) =
        getPreference(appContext).edit().putString(key, value).apply()

    // To retrieve values from shared preferences:
    fun getBoolean(appContext: Context, key: String?, defaultValue: Boolean?): Boolean =
        getPreference(appContext).getBoolean(key, defaultValue!!)

    fun getInteger(appContext: Context, key: String?, defaultValue: Int): Int =
        getPreference(appContext)
            .getInt(key, defaultValue)

    fun getString(appContext: Context, key: String?, defaultValue: String?): String? =
        getPreference(appContext)
            .getString(key, defaultValue)


}

使用

PreferenceHelper.setString(context,"CUSTOMER_NAME", "HITESH")

Toast.makeText(context, "Hello " + PreferenceHelper.getString(context,"CUSTOMER_NAME", "User"), Toast.LENGTH_LONG).show()

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);

}

使用

PreferenceHelper.setString(context,"CUSTOMER_NAME", "HITESH")

Toast.makeText(context, "Hello " + PreferenceHelper.getString(context,"CUSTOMER_NAME", "User"), Toast.LENGTH_LONG).show()

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();

你还没有说明在这之后你对prefsEditor对象做了什么，但是为了持久化首选项数据，你还需要使用:

prefsEditor.commit();

将数据存储在SharedPreference中

SharedPreferences mprefs = getSharedPreferences(AppConstant.PREFS_NAME, MODE_PRIVATE)
mprefs.edit().putString(AppConstant.USER_ID, resUserID).apply();
