我是JSON中的新成员,并且在为后续的JSON输入创建POJO时遇到问题。嵌套json的POJO
[
{
"score":1,
"popularity":3,
"name":"Brad Pitt",
"id":287,
"biography":"test",
"url":"http://www.themoviedb.org/person/287",
"profile":[
{
"image":{
"type":"profile",
"size":"thumb",
"height":68,
"width":45,
"url":"http://d3gtl9l2a4fn1j.cloudfront.net/t/p/w45/w8zJQuN7tzlm6FY9mfGKihxp3Cb.jpg",

}
}

我已经创建了三个POJO对他们的这个人是主要负责人类这其中蕴含配置文件对象也。简介对象返回图像列表:
public class Person implements Serializable {
private static final long serialVersionUID = 6794898677027141412L;
public String biography;
public String id;
public String last_modified_at;
public String name;
public String popularity;
public String score;
public String url;
public String version;
public ArrayList<Profile> profile;
//getters and setters
}
public class Profile implements Serializable {
private static final long serialVersionUID = -6482559829789740926L;
public ArrayList<Image> image;
}
public class Image implements Serializable {
private static final long serialVersionUID = -2428562977284114465L;
public String type;
public String url;
public String size;
public int width;
public int height;
}
我使用GSON检索数据:
Gson gson = new Gson();
Type collectionType = new TypeToken<List<Person>>(){}.getType();
List<Person> details = gson.fromJson(json, collectionType);
当我运行此我得到:
02-17 11:04:50.531: E/AndroidRuntime(405): Caused by: com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 3
更新图片POJO:
public class Image implements Serializable {
private static final long serialVersionUID = -2428562977284114465L;
private Object image;
public class ImageInner {
public static final String SIZE_ORIGINAL = "original";
public static final String SIZE_MID = "mid";
public static final String SIZE_COVER = "cover";
public static final String SIZE_THUMB = "thumb";
public static final String TYPE_PROFILE = "profile";
public static final String TYPE_POSTER = "poster";
public String type;
public String url;
public String size;
public int width;
public int height;
}
}
谢谢
嗨布莱恩,我会检查收到的JSON并更新人POJO如你所述。当我尝试时,我会提供信息。谢谢 – 2013-02-18 12:26:51
谢谢你现在完美。 – 2013-02-18 20:59:50
嗨布莱恩,我想我错过了这个答案中的一点,因为即使图像属性填充,当我得到人的列表观察到所有的图像属性为空。你有什么想法吗? – 2013-02-20 07:38:33
