问题：
自定义枚举属性提供不允许的错误字符串类型
阙弘博
大家好，我正在尝试实现一个自定义TextView与字体。我决定使用RobotoTextView。我在资产中也有字体文件夹。我在**custom:typeface=“robotolight”**时出错。
错误：

是添加自定义命名空间的旧样式。尝试使用以下方法自动替换正确的包--

但有些时候我们需要控制枚举的类型，那么我们可以 Enum 派生出自定义类来满足这种需要。通过修改上面的例子： #!/usr/bin/env python3 # -*- coding: UTF-8 -*- from enum import Enum, unique Enum('Month', ('Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Au

enum 关键字允许创建一个代表数个可能变量的数据的类型（原文：The enum keyword allows the creation of a type which may be one of a few different variants.若您对此句有 更好的翻译或理解，希望指出来，谢谢。）。在 struct 中任何合法的变量在 enum 同样是合法的。 // 隐藏未使用代码警告的属性。

这就是所谓的扩展枚举。我知道它管用--我以前试过并用过很多次。我知道如果这是您应该对枚举做的事情，可能会有讨论--我认为是的，因为您仍然有您定义的常量，但它们只是包含了一些更多的信息（仍然是常量）。（另外：我看过这个例子，java枚举上的自定义字段没有序列化，我认为它们也遵循了我在如何生成枚举上的自定义属性方面的思路）。 现在，我究竟应该如何从Eclipse EMF模型生成这样的东西呢？我甚至不知

问题内容： 我已经阅读了Java和C++之间的枚举差异问题？但是我还是很困惑。 我想以下返回相关的字符串： 据我所读，这应该是可能的。只是希望您对如何实现它有所了解。 问题答案： 简短答案 您需要一个构造函数，一个字段和一个吸气剂。 建设者 枚举类型可以具有构造函数，只要它们的访问级别为私有或默认（包私有）即可。除了枚举声明本身之外，您不能直接调用这些构造函数。与类相似，当定义不带参数的枚举常量时
