Android解析JSON数据并添加到LIstView中。出现了一些问题。

[测试0001]

JSON解析数据并将数据添加到ListView中。

请问这样是什么原因？


path地址确认无误= =
这是用网页打开patg地址
{"code":200,"message":"调用成功","data":{"mem_message_records":[{"message_disease_typeid":"1","message_disease_type":"心血管系统"},{"message_disease_typeid":"2","message_disease_type":"外围血管疾病"},{"message_disease_typeid":"3","message_disease_type":"脑血管疾病"},{"message_disease_typeid":"4","message_disease_type":"肺部疾病"},{"message_disease_typeid":"5","message_disease_type":"代谢疾病"},{"message_disease_typeid":"6","message_disease_type":"周围神经疾病"},{"message_disease_typeid":"7","message_disease_type":"其他疾病"}],"mem_message_recordss":[[{"message_diseaseid":"1","message_disease":"冠状动脉疾病"},{"message_diseaseid":"2","message_disease":"心绞痛"},{"message_diseaseid":"3","message_disease":"心肌梗死"},{"message_diseaseid":"4","message_disease":"冠状动脉血运重建"},{"message_diseaseid":"5","message_disease":"充血性心力衰竭"}],[{"message_diseaseid":"6","message_disease":"闭塞性周围动脉粥样硬化"},{"message_diseaseid":"7","message_disease":"血栓行静脉炎"}],[{"message_diseaseid":"8","message_disease":"脑血栓"},{"message_diseaseid":"9","message_disease":"短暂性脑供血不足"},{"message_diseaseid":"10","message_disease":"脑出血"}],[{"message_diseaseid":"11","message_disease":"慢性支气管炎"},{"message_diseaseid":"12","message_disease":"慢性阻塞性肺病"},{"message_diseaseid":"13","message_disease":"支气管哮喘"},{"message_diseaseid":"14","message_disease":"间质性肺病"},{"message_diseaseid":"15","message_disease":"囊性肺纤维化"}],[{"message_diseaseid":"16","message_disease":"1型糖尿病"},{"message_diseaseid":"17","message_disease":"2型糖尿病"},{"message_diseaseid":"18","message_disease":"糖尿病肾病"}],[{"message_diseaseid":"19","message_disease":"糖尿病性周围精神病"},{"message_diseaseid":"20","message_disease":"自主神经性病变"}],[{"message_diseaseid":"21","message_disease":"高血压"},{"message_diseaseid":"22","message_disease":"视网膜病变"},{"message_diseaseid":"23","message_disease":"恶性肿瘤"},{"message_diseaseid":"24","message_disease":"脑卒中"},{"message_diseaseid":"25","message_disease":"重性精神疾病"},{"message_diseaseid":"26","message_disease":"结核病"},{"message_diseaseid":"27","message_disease":"肝炎"},{"message_diseaseid":"28","message_disease":"先天畸形"},{"message_diseaseid":"29","message_disease":"其它"}]]}}

这是我自己本地的打印的解析数据的返回


JiBingbean{code='200', message='调用成功', data=JiBinglist{mem_uid='null', mem_message_records=[JiBingdata{message_diseaseid='null', message_disease_typeid='1', message_disease='null', message_disease_type='心血管系统'}, JiBingdata{message_diseaseid='null', message_disease_typeid='2', message_disease='null', message_disease_type='外围血管疾病'}, JiBingdata{message_diseaseid='null', message_disease_typeid='3', message_disease='null', message_disease_type='脑血管疾病'}, JiBingdata{message_diseaseid='null', message_disease_typeid='4', message_disease='null', message_disease_type='肺部疾病'}, JiBingdata{message_diseaseid='null', message_disease_typeid='5', message_disease='null', message_disease_type='代谢疾病'}, JiBingdata{message_diseaseid='null', message_disease_typeid='6', message_disease='null', message_disease_type='周围神经疾病'}, JiBingdata{message_diseaseid='null', message_disease_typeid='7', message_disease='null', message_disease_type='其他疾病'}]}}


请一下哪边出了问题？我还是我实体类写错了

不知道你说的问题是什么，是出现了什么问题？

[hadis_fei]

你的jiBingbean应该是解析 data=JiBinglist 里面的数据吧，你好像直接解析整个json数据了

就是解析这个JSON数组的时候，我总是解析出一半的数据。另外一半的数据总是显示NULL值。 问题我已经找到了。就是这个接口地址里面是两个数组。而我只解析了 一个。这是后来我问了一个写服务器端的朋友帮我查看出来的。 谢谢。 现在的问题是，我将服务器给的参数构建了一个实体类来接收服务器给的值。 但是给的接口文档上确实两个数组。 现在已经解析出了疾病类型数组，用了相同的方法构建实体类想解析出疾病名称数组。但是程序运行报错，错误是， Expected BEGIN_OBJECT but was BEGIN_ARRAY at line 1 column 520 path $.data.mem_message_recordss[0] 这个错误是说我按照对象解析的，其实它是一个数组。 下面是我构建的实体类。 这是最里层的两个， //疾病名称 public class JiBingdataname { private String message_diseaseid; private String message_disease; ｝ //疾病类型 public class JiBingdata { private String message_disease_type; private String message_disease_typeid; ｝ //外一层 public class JiBinglist { private List<JiBingdata> mem_message_records; private List<JiBingdataname> mem_message_recordss; ｝ //最外层 public class JiBingbean { private String code; private String message; private JiBinglist data; ｝ 这边是我的解析代码 //解析JSON数据 private class Mythread extends Thread { @Override public void run() { System.out.println("....启动线程"); //网络请求路径 String path = HttpInfo.PATH + HttpInfo.GET_JIBINGLIST + HttpInfo.ID; String jsonString = HttpUtils.getJsonContent(path); Gson gson = new Gson(); System.out.println("------------------------" + path); //解析json数据 jiBingbean = gson.fromJson(jsonString, JiBingbean.class); System.out.println("....启动线程" + jiBingbean); //解析成功后发送msg给UI主线程 Message msg = new Message(); msg.what = 101; myHandler.sendMessage(msg); } } 这边是我的接口文档信息。 { "code":200, "message":"调用成功", "data":{ "mem_message_records":[ { "message_disease_typeid":"1", "message_disease_type":"心血管系统" }, { "message_disease_typeid":"2", "message_disease_type":"外围血管疾病" }, { "message_disease_typeid":"3", "message_disease_type":"脑血管疾病" }, { "message_disease_typeid":"4", "message_disease_type":"肺部疾病" }, { "message_disease_typeid":"5", "message_disease_type":"代谢疾病" }, { "message_disease_typeid":"6", "message_disease_type":"周围神经疾病" }, { "message_disease_typeid":"7", "message_disease_type":"其他疾病" } ], "mem_message_recordss":[ [ { "message_diseaseid":"1", "message_disease":"冠状动脉疾病" }, { "message_diseaseid":"2", "message_disease":"心绞痛" }, { "message_diseaseid":"3", "message_disease":"心肌梗死" }, { "message_diseaseid":"4", "message_disease":"冠状动脉血运重建" }, { "message_diseaseid":"5", "message_disease":"充血性心力衰竭" } ], [ { "message_diseaseid":"6", "message_disease":"闭塞性周围动脉粥样硬化" }, { "message_diseaseid":"7", "message_disease":"血栓行静脉炎" } ], [ { "message_diseaseid":"8", "message_disease":"脑血栓" }, { "message_diseaseid":"9", "message_disease":"短暂性脑供血不足" }, { "message_diseaseid":"10", "message_disease":"脑出血" } ], [ { "message_diseaseid":"11", "message_disease":"慢性支气管炎" }, { "message_diseaseid":"12", "message_disease":"慢性阻塞性肺病" }, { "message_diseaseid":"13", "message_disease":"支气管哮喘" }, { "message_diseaseid":"14", "message_disease":"间质性肺病" }, { "message_diseaseid":"15", "message_disease":"囊性肺纤维化" } ], [ { "message_diseaseid":"16", "message_disease":"1型糖尿病" }, { "message_diseaseid":"17", "message_disease":"2型糖尿病" }, { "message_diseaseid":"18", "message_disease":"糖尿病肾病" } ], [ { "message_diseaseid":"19", "message_disease":"糖尿病性周围精神病" }, { "message_diseaseid":"20", "message_disease":"自主神经性病变" } ], [ { "message_diseaseid":"21", "message_disease":"高血压" }, { "message_diseaseid":"22", "message_disease":"视网膜病变" }, { "message_diseaseid":"23", "message_disease":"恶性肿瘤" }, { "message_diseaseid":"24", "message_disease":"脑卒中" }, { "message_diseaseid":"25", "message_disease":"重性精神疾病" }, { "message_diseaseid":"26", "message_disease":"结核病" }, { "message_diseaseid":"27", "message_disease":"肝炎" }, { "message_diseaseid":"28", "message_disease":"先天畸形" }, { "message_diseaseid":"29", "message_disease":"其它" } ] ] } }

你只解析了这个mem_message_records，没解析这个mem_message_recordss，你用json格式化一下就看出问题了

对的。我也是我后来才发现了这个问题。 我这边新开了一个帖子。 http://ask.csdn.net/questions/238470 我想将两个数组拼接起来的。但是程序报错 java.lang.IllegalStateException: Expected BEGIN_OBJECT but was BEGIN_ARRAY at line 1 column 520 path $.data.mem_message_recordss[0] 新的帖子里我附了程序代码。

我构建了实体类，将他们一层一层嵌套一起来的。 我成功解析过出一个，但是同时解析两个的时候就出现问题了 我这边新开了一个帖子。 http://ask.csdn.net/questions/238470 我想同样的方法将两个数组拼起来的。结果不行。
