Android Youtube API JSON-C 使用 GSON 解析

Question

我正在尝试开发一个 Android 应用程序来检索特定用户的视频，并且我想使用 JSON-C 响应格式来保持较小的大小。一旦我收到我的回复，格式如下:

{
"apiVersion":"2.1",
"data":{
    "updated":"2012-12-02T14:40:07.424Z",
    "totalItems":175,
    "startIndex":1,
    "itemsPerPage":25,
    "items":[
        {
            "id":"rnzJ5x3sWyk",
            "uploaded":"2012-12-01T20:19:07.000Z",
            "updated":"2012-12-01T20:19:07.000Z",
            "uploader":"user",
            "category":"News",
            "title":"L'ALLUVIONE HA DISTRUTTO LE ROULOTTE DELLE VACANZE",
            "description":"Ad Albinia,in un rimessaggio per roulotte, il proprietario, i volontari e i vacanzieri che sono soliti passare l'estate qui, si sono rimboccati le maniche per ripulire dal fango le tante \"case delle vacanze\" distrutte dall'alluvione",
            "thumbnail":{
                "sqDefault":"http://i.ytimg.com/vi/rnzJ5x3sWyk/default.jpg",
                "hqDefault":"http://i.ytimg.com/vi/rnzJ5x3sWyk/hqdefault.jpg"
            },
            "player":{
                "default":"http://www.youtube.com/watch?v=rnzJ5x3sWyk&feature=youtube_gdata_player",
                "mobile":"http://m.youtube.com/details?v=rnzJ5x3sWyk"
            },
            "content":{
                "5":"http://www.youtube.com/v/rnzJ5x3sWyk?version=3&f=user_uploads&app=youtube_gdata",
                "1":"rtsp://v1.cache2.c.youtube.com/CigLENy73wIaHwkpW-wd58l8rhMYDSANFEgGUgx1c2VyX3VwbG9hZHMM/0/0/0/video.3gp",
                "6":"rtsp://v6.cache2.c.youtube.com/CigLENy73wIaHwkpW-wd58l8rhMYESARFEgGUgx1c2VyX3VwbG9hZHMM/0/0/0/video.3gp"
            },
            "duration":136,
            "viewCount":2,
            "favoriteCount":0,
            "commentCount":0,
            "accessControl":{
                "comment":"allowed",
                "commentVote":"allowed",
                "videoRespond":"moderated",
                "rate":"allowed",
                "embed":"allowed",
                "list":"allowed",
                "autoPlay":"allowed",
                "syndicate":"allowed"
            }
        },
and others items....

当我设置模型类以反序列化它时，它应该是什么样子 我是否必须包含所有元素，即使是那些我不感兴趣的元素？

 public class SearchResponse {

    public Container data;

  }

指的是

import java.util.ArrayList;

import com.google.gson.annotations.SerializedName;

public class Container {

public ArrayList<Items> results;

@SerializedName("totalItems")
public int totalItems;

@SerializedName("startIndex")
public int startIndex;

@SerializedName("itemsPerPage")
      public int itemsPerPage;
}

对于每个项目:

import com.google.gson.annotations.SerializedName;

public class Items {

@SerializedName("id")
public String id;

@SerializedName("uploaded")
public String uploaded;

@SerializedName("category")
public String category;

@SerializedName("title")
public String title;

@SerializedName("description")
public String description;

public Thumbnail thumbnail;

@SerializedName("duration")
public int duration;


}

以及每个缩略图

import com.google.gson.annotations.SerializedName;

public class Thumbnail {

@SerializedName("sqdefault")
      public String sqdefault;

@SerializedName("hqdefault")
public String hqdefault;

}

我认为“数据”部分正在杀死我。

如果您已经这样做了，有人可以帮忙或给我一些例子吗？

提前致谢

Answer 1

这个:

public ArrayList<Items> results;

需要:

public ArrayList<Items> items;

或者:

@SerializedName("items") public ArrayList<Items> results;

它应该可以正常工作。

不，您不必在 POJO 中包含所有字段。 JSON 中存在的任何您没有的字段都将被静默忽略。
