我想在我的simplexml改装转换器中添加一个新的日期格式,根据:Parse date with SimpleFramework
class DateTransformer(format: String) : Transform<Date> {
private val formatter = SimpleDateFormat(format) // SimpleDateFormat is not thread safe!
@Throws(Exception::class)
override fun read(value: String): Date {
return formatter.parse(value)
}
@Throws(Exception::class)
override fun write(value: Date): String {
return formatter.format(value)
}
}
我不知道如何将它整合到Retrofit转换器中,如果有的话,会喜欢你们的一些意见!
谢谢!

根据您链接的答案,您可以通过向RegistryMatcher
提供Serializer
来使SimpleXML解析日期。
此外,通过Retrofit的SimpleXml转换器,您可以将Serializer
传递给SimpleXmlConverterFactory
。
