Android 如何从jsonObject获取变量中的值？
我的Soap Web服务对此做出如下响应：Android 如何从jsonObject获取变量中的值？,android,web-services,soap,Android,Web Services,Soap,我的Soap Web服务对此做出如下响应： [{"msg":"1,UDDAIPUR","Value1":null,"Value2":null,"Value3":null,"Value4":null,"Value5":null,"Value6":null,"Value7":null,"Value8":null,"Value9":null,"Value10":null}] 下面是我的任务- //String TAG_IDS And TAG_NAMES private static fina

//字符串标记ID和标记名称
私有静态最终字符串标记\u ID\u fillstateid=“nSerialNo”；
//为城市调用web服务
类async\u fillCity扩展了AsyncTask{
@凌驾
受保护的字符串doInBackground（字符串…参数）{
SoapObject请求=新的SoapObject（名称空间、方法名称和填充城市）；
request.addProperty（参数_fillcity，“1”）；//添加参数
SoapSerializationEnvelope=新的SoapSerializationEnvelope（SoapEnvelope.VER11）；//设置soap版本
envelope.setOutputSoapObject（请求）；
envelope.dotNet=true；
试一试{
HttpTransportSE androidHttpTransport=新的HttpTransportSE（url）；
androidHttpTransport.call（soap_action_fillcity，信封）；//这是将调用Web服务的实际部分
//SoapPrimitive prim=（SoapPrimitive）envelope.getResponse（）；//从信封正文获取SoapResult。
SoapObject响应=（SoapObject）envelope.bodyIn；
//resultstate=prim.toString（）；
resultcity=response.getPropertyAsString（0.toString（）；
if（resultcity！=null）{
试一试{
JSONArray resultarray=新的JSONArray（resultcity）；
对于（int i=0；i你可以像这样把身份证和城市分开-
JSONArray resultarray = new JSONArray(resultcity);
for (int i = 0; i < resultarray.length(); i++) {
JSONObject c = resultarray.getJSONObject(i);
String idCity = c.getString(msg);}
快乐到快乐…您可以像这样分别获得id和city-
JSONArray resultarray = new JSONArray(resultcity);
for (int i = 0; i < resultarray.length(); i++) {
JSONObject c = resultarray.getJSONObject(i);
String idCity = c.getString(msg);}
Happy to Happy…在您的json结果中没有类似于“nSerialNo”的值，这就是您出错的原因。JsonTank中没有用于响应的键
nSerialNonSerialNo
