比较笨的方法可以把 AdBaseBeanList 改成 String，数据接收到之后 用gson在转一下。

感谢。
是的，这也是我目前采用的 ，但感觉很不舒服，既然我用了GsonConverterFactory，就势必想要一步到位，直接返回bean。我试图重写Converter但没有成功，我希望通过重写Converter来解决这个问题。

这很明显是后端同学偷懒的结果，json 写成这样...我觉得与其在端上妥协，做这种 trick 的处理。还不如跟后端沟通一下，给过来标准的 json 格式。
另外我觉得 @bricklazy 提到的处理方式是最简单有效的。其实你也已经用了 RxJava，只需要再 map 一次就 ok 了。重写 Converter 就复杂了，而且也不通用。
