Java Android改造中的动态嵌套数组解析,java,android,json,retrofit2,Java,Android,Json,Retrofit2,在下面的json中，我能够读取类别字段。如何读取动态属性4和1 { "categories":[ { "mcategory_id":"4", "mcategory_name":"Band" }, { "mcategory_id":"1", "mcategory_name":"Basic Effects" }, { "mcategory_id":"3", "mcategory_n

在下面的json中，我能够读取类别字段。如何读取动态属性4和1

     {  
   "categories":[  
  {  
     "mcategory_id":"4",
     "mcategory_name":"Band"

  },
  {  
     "mcategory_id":"1",
     "mcategory_name":"Basic Effects"

  },
  {  
     "mcategory_id":"3",
     "mcategory_name":"Bg Image Card"

  }

],
        "effect_list":[{  
  "4":[  
     {  
        "effects_id":"18",
        "effects_name":"Band 1"

     },
     {  
        "effects_id":"19",
        "effects_name":"Band 2"

     }

  ],
  "1":[  
     {  
        "effects_id":"1",

     }
    ]
