我正在尝试使用retrofit rxjava来进行嵌套的api调用.基本上我必须构建一个Library对象列表.每个Library对象都有一个Authors列表,每个Author对象都有一个Books列表.这就是我的json的结构.

图书馆json –

{
 title: "Library",items: [
      {
        title: "Library1"
        image: "http://example.com/image/101/image_lib1.png"
        url: "http://example.com/api/1"
      },{
        title:"Library2"
        image: "http://example.com/image/101/image_lib2.png"
        url: "http://example.com/api/2"
      },{
        title:"Library3"
        image: "http://example.com/image/101/image_lib3.png"
        url: "http://example.com/api/3"
      }
   ]
 }

和作者json-

{
 title: "Authors",items: [
      {
        title: "J.K Rowling"
        image: "http://example.com/image/101/image_author1.png"
        url: "http://example.com/api/101"
      },{
        title:"Mark Twain"
        image: "http://example.com/image/101/image_author2.png"
        url: "http://example.com/api/201"
      },{
        title:"Charles Dickens"
        image: "http://example.com/image/101/image_author3.png"
        url: "http://example.com/api/301"
      }
   ]
 }

和书籍json-

{
description: Books,imageurl: "http://example.com/image/101/image_101.png",items: [
   {
     id: 101,title: "Oliver Twist ",description: "some description"
   },{
   id: 1011,title: "Hard times",description: "some more description."
  }
}
]
}

我的api界面如下.

  @GET("/api/")
  ObservableFeedId}")
  ObservableFeedId") String FeedId);

  @GET("/api/{FeedId}")
  ObservableFeedId") String FeedId);
