我只需要帮助我的json数据实际上我的mysql表包含很多字段，我知道如何以json格式转换整个数据并将其解析为android应用程序但是我想根据条件来获取特定的数据行其中id = 1，name =＆＃34; some＆＃34;，这是我迄今为止尝试过的，但没有成功。

我的json是这样的
{"list":[{"email":"vips@gmail.com","name":"Vipul
S","rank":"1","accuracy":"80"},
{"email":"karan@gmail.com","name":"karan
S","rank":"3","accuracy":"30"},
{"email":"vikas@gmail.com","name":"Vikas
S","rank":"2","accuracy":"83"}]}
我的xml文件有点大，所以我没有在这里发布，但是我已经检查了ID并且它都没问题。
所以问题是我得到了所有数据，但我只想根据电子邮件一次发布一行，但现在TextView不会发布数据。
答案 0 :(得分：0)
我这样做了一切都保持不变只是改变
JSONObject jobj = new JSONObject(response);
JSONArray result = jobj.getJSONArray(Config.JSON_ARRAY_Result);
for(int i=0;i<result.length();i++) {
String gmail = result.getJSONObject(i).getString(Config.email);
到
JSONObject jobj = new JSONObject(response);
JSONArray result = jobj.getJSONArray(Config.JSON_ARRAY_Result);
for(int i=0;i<result.length();i++) {
JSONObject Data = result.getJSONObject(i);
String gmail =
result.getJSONObject(i).getString(Config.email);
这是我在函数getResults（）的try块中缺少的行，因为没有传递任何引用JSONObject Data = result.getJSONObject（i）;
所以用它来帮助你自己......谢谢
