android中注解的简单实用

//这是注解类

在这个注解类中我们声明了两个注解

1、@Target

/**  * Class, interface or enum declaration.  */ TYPE
/**  * Field declaration.  */ FIELD,
/**  * Method declaration.  */ METHOD,
/**  * Parameter declaration.  */ PARAMETER,
/**  * Constructor declaration.  */ CONSTRUCTOR,
/**  * Local variable declaration.  */ LOCAL_VARIABLE,
/**  * Annotation type declaration.  */ ANNOTATION_TYPE,
/**  * Package declaration.  */ PACKAGE
