Java Android的Gson

我正在尝试使用Gson解析此JSON：

            },
            "day5": {
                "date": "2013-08-17"
            },
            "day6": {
                "date": "2013-08-18"
            }
        },
        "title": "title"
    }]
}

我用以下代码解析JSON：

Gson gson = new Gson();
new GsonBuilder().serializeNulls().create();
Reader reader = new InputStreamReader(source);
response = gson.fromJson(reader, ResponseShow.class);

这是我的

public class day0 {

    @SerializedName("date")
    public String date;         
    public List<periods> periods; 
}

public Map<String, Day> schedules;

问题是，我在尝试分析

day0

时遇到以下错误：

Error: java.lang.IllegalStateException: Expected BEGIN_ARRAY goal was BEGIN_OBJECT at line 1 column 2414

---

你的问题在类

openinghours

（顺便说一句，哪个应该是大写的！）。在这里，您试图将字段

“schedules”

解析为一个

列表

，正如您在JSON中看到的，它不是一个

列表

，而是一个对象（它被

{}

包围）

具体地说，

“schedules”

字段如下所示：

"schedules": {
    "day0": {
        ...
    },
    "day1": {
        ...
    },
    ...
}

因此，对于您来说，最快的解决方案就是将

openinghours

类中的属性

schedules

的类型替换为：

public schedules schedules;

因为JSON字段

“schedules”

是一个对象，它包含多个字段

day0

，

day1

，等等。。。而这正是你们班的课程安排。。。所以，这应该对你有用

---

无论如何，最好的解决方案是在

openinghours

类中使用

Map

this：

public class ResponseShow {

    @SerializedName("status")
    public String status;    
    @SerializedName("lang")
    public String lang;    
    @SerializedName("guid")
    public String guid;    
    @SerializedName("name")
    public String name;    
    @SerializedName("tags")
    public String tags;    
    @SerializedName("address")
    public String address;    
    @SerializedName("description")
    public String description;    
    @SerializedName("size")
    public String size;    
    @SerializedName("url")
    public String url;    
    @SerializedName("email")
    public String email;    
    @SerializedName("fax")
    public String fax;    
    @SerializedName("tel")
    public String tel;    
    @SerializedName("total_votes")
    public String total_votes;    
    @SerializedName("total_values")
    public String total_values;    
    @SerializedName("rate")
    public String rate;    
    @SerializedName("open2424")
    public String open2424;    
    @SerializedName("category_main_name")
    public String category_main_name;    
    @SerializedName("category_name")
    public String category_name;    
    @SerializedName("category_main_name2")
    public String category_main_name2;    
    @SerializedName("category_name2")
    public String category_name2;    
    @SerializedName("category_main_name3")
    public String category_main_name3;    
    @SerializedName("category_name3")
    public String category_name3;    
    @SerializedName("park_type")
    public String park_type;    
    @SerializedName("park_handicap")
    public String park_handicap;    
    @SerializedName("park_free")
    public String park_free;    
    @SerializedName("park_description")
    public String park_description;    
    @SerializedName("datemodinfo")
    public String datemodinfo;    
    @SerializedName("sponsor")
    public String sponsor;    
    @SerializedName("sponsorstart")
    public String sponsorstart;    
    @SerializedName("sponsorend")
    public String sponsorend;    
    @SerializedName("town")
    public String town;    
    @SerializedName("area")
    public String area;    
    @SerializedName("latitude")
    public String latitude;    
    @SerializedName("longitude")
    public String longitude;    
    @SerializedName("distance_info")
    public Map<String, String> distance_info = new HashMap<String, String>();    
    @SerializedName("zip")
    public String zip;    
    @SerializedName("image")
    public String image;    
    @SerializedName("ligoo_url")
    public String ligoo_url;    
    @SerializedName("open")
    public int open;    
    public List<openinghours> openinghours;    
    @SerializedName("query")
    public String query;
}

public class openinghours {

    public List<schedules> schedules;       
    @SerializedName("title")
    public String title;

}

public class schedules {

    public List<day0> day0;
    public List<day1> day1;
    public List<day2> day2;
    public List<day3> day3;
    public List<day4> day4;
    public List<day5> day5;
    public List<day6> day6;
}

public class day0 {

    @SerializedName("date")
    public String date;         
    public List<periods> periods; 
}

public Map<String, Day> schedules;

公共地图时间表；

这是最好的选择，因为这正是JSON字段

“schedules”

所表示的。。。此外，通过这种方式，您只能有一个类

天

，而不是许多类

天0

，

天1

，等等。。。这就更有意义了

尝试替换

public class openinghours {
    public List<schedules> schedules;       
    @SerializedName("title")
    public String title;
}

您可以为距离定义一个类。\u info（）：

//更改

@SerializedName("distance_info")
public Map<String, String> distance_info = new HashMap<String, String>();

也发布与解析相关的代码。问题涉及到那些代码。您提供的json有一个错误。它有一个结束']'但没有打开'['。这可能是一个复制粘贴错误，但也许你会添加第一个字符，以便更容易发现真正的问题。你的day0类是什么？即使你不需要为day0和其他几天创建不同的类，因为它只是更改了标签，否则所有的孩子都是一样的。我已经更改了问题…@Buchssullivan：让我再重复一遍如果你认为它是有效的和有用的，你可以接受这个答案…或者你可以随时评论如果你需要更多的帮助…
