改造@FieldMap参数类型必须是地图

Question

我想实现一个请求，我可以用Retrofit所以发在同一时间多个请求，我创建了一个这样的接口：

@FormUrlEncoded 
@POST("/locations/add.json") 
void sendMultipleLocations(@Query("token")String token, @FieldMap List<Map<String, String>> multipleLocations, Callback<String> callback); 

然后，我在列表中建立地图数据，然后推送。

private void sendLocations(List<Map<String, String>> multipleLocations) { 
    RestClient.get(this).sendMultipleLocations("token", multipleLocations, new Callback<String>() { 
     @Override 
     public void success(String s, Response response) { 
      Log.e("MultipleLocationResp", s); 
     } 

     @Override 
     public void failure(RetrofitError error) { 
      error.printStackTrace(); 
     } 
    }); 
} 

而且我不断收到此错误：

java.lang.IllegalArgumentException: PodApi.sendMultipleLocations: @FieldMap parameter type must be Map. (parameter #2)

你必须使用一个地图，不是地图列表。 @FieldMap Map<String, String> multipleLocations。
