这样的json 如何用fastjson 解析到关联实体类 然后给 listview 使用

Answer 1

项目github主页上的文档就说到怎么做了，看文档吧：https://github.com/alibaba/fa...

Answer 2

List<List<T>>

Answer 3

如果可行话建议修改json格式，类似这样的话，就可以用map来接受了{ "5": "曹颖","9": "胡嘉璐","10": "陈晨","19": "陈晨"}
，或者改成
{
"id":"5",
"name":"曹颖"
}

Answer 4

1、如果你是用的androidstudio，请安装插件 gsonformat （file-settings-plugins，搜索库）
2、添加依赖 compile 'com.alibaba:fastjson:1.1.56.android' ;
3、送你代码

public class FastJsonUtils {

    /**
     * 功能描述：把JSON数据转换成普通字符串列表
     * 
     * @param jsonData
     *            JSON数据
     * @return
     * @throws Exception
     * @author myclover
     */
    public static List<String> getStringList(String jsonData) throws Exception {
        return JSON.parseArray(jsonData, String.class);
    }

    /**
     * 功能描述：把JSON数据转换成指定的java对象
     * 
     * @param jsonData
     *            JSON数据
     * @param clazz
     *            指定的java对象
     * @return
     * @throws Exception
     * @author myclover
     */
    public static <T> T getSingleBean(String jsonData, Class<T> clazz)
            throws Exception {
        return JSON.parseObject(jsonData, clazz);
    }

    /**
     * 功能描述：把JSON数据转换成指定的java对象列表
     * 
     * @param jsonData
     *            JSON数据
     * @param clazz
     *            指定的java对象
     * @return
     * @throws Exception
     * @author myclover
     */
    public static <T> List<T> getBeanList(String jsonData, Class<T> clazz)
            throws Exception {
        return JSON.parseArray(jsonData, clazz);
    }

    /**
     * 功能描述：把JSON数据转换成较为复杂的java对象列表
     * 
     * @param jsonData
     *            JSON数据
     * @return
     * @throws Exception
     * @author myclover
     */
    public static List<Map<String, Object>> getBeanMapList(String jsonData)
            throws Exception {
        return JSON.parseObject(jsonData,
                new TypeReference<List<Map<String, Object>>>() {
                });
    }

    /**
     * 将网络请求下来的数据用fastjson处理空的情况，并将时间戳转化为标准时间格式
     * @param result
     * @return
     */
    public static String dealResponseResult(String result) {
        result = JSONObject.toJSONString(result,
                SerializerFeature.WriteClassName,
                SerializerFeature.WriteMapNullValue,
                SerializerFeature.WriteNullBooleanAsFalse,
                SerializerFeature.WriteNullListAsEmpty,
                SerializerFeature.WriteNullNumberAsZero,
                SerializerFeature.WriteNullStringAsEmpty,
                SerializerFeature.WriteDateUseDateFormat,
                SerializerFeature.WriteEnumUsingToString,
                SerializerFeature.WriteSlashAsSpecial,
                SerializerFeature.WriteTabAsSpecial);
        return result;
    }
}

4、新建 class ，使用 gsonformat 插件 转为 『实体类』
5、最后一步

CourseModel wangDaiM =  null ;
wangDaiM = FastJsonUtils.getSingleBean(response, CourseModel.class);
