我发送的详细信息要使用KSOAP使用Web服务存储在数据库中。我使用visual studio来创建Web服务。网络服务工作正常。将详细信息插入数据库后,将返回一个字符串。问题是这个字符串是空的,也许我得到响应的方式有问题。我一直试图找出错误很长一段时间。请帮忙

public class Registration extends Activity{
private static final String SOAP_ACTION = "http://tempuri.org/register";
private static final String OPERATION_NAME = "register";
private static final String WSDL_TARGET_NAMESPACE = "http://tempuri.org/";
private static final String SOAP_ADDRESS = "http://10.0.2.2:58076/WebSite1/Service.asmx";

@Override

super.onCreate(savedInstanceState);

sqlRegister.setOnClickListener(new View.OnClickListener() {

    public void onClick(View v) {
        switch (v.getId()){
        case R.id.bRegister:

         }catch(Exception e){
            e.printStackTrace();

您的网络服务正在返回String。 尝试使用它来解决您的问题

          Object result = envelope.getResponse();

当您的webservice返回byte []类型的值时,您可以这样做:

          SoapObject response=(SoapObject)envelope.bodyIn;

希望有所帮助
