推荐答案

如

5.2.1应用程序

可以使用@Context批注将应用程序提供的Application子类的实例注入到类字段或方法参数中.对Application子类实例的访问允许将配置信息集中在该类中.请注意，不能将其注入Application子类本身，因为这将创建循环依赖关系.

The instance of the application-supplied Application subclass can be injected into a class field or method parameter using the @Context annotation. Access to the Application subclass instance allows configuration information to be centralized in that class. Note that this cannot be injected into the Application subclass itself since this would create a circular dependency.

但是根据我的经验，它很可能不是实际实例，而是代理.另外，如果您要更改其中的任何内容，我不确定是否有可能.它可能是只读的.

but from I've experienced, it will most likely not be the actual instance, but a proxy. Also if you're looking to alter anything on it, I'm not sure it's possible. It might be read-only.
