kSOAP2与webservices通信C＃

Question

我想从android用户发送登录凭证到通过visual studio在本地主机上运行的C＃web服务。我已经使用KSOAP2进行SOAP通信，并希望将登录信息发送到Web服务并在UI中进行打印。我已经使用Asynctask，但我一直在这里发布下面的错误。

ksoap 2 communication - sending the asynctask result to UI thread and print

能有一个人，请帮助我哪里错了?????

public class MainActivity extends Activity { 

     EditText un,pw; 
     TextView tv; 
     Button test; 
     /** Called when the activity is first created. */ 
     @Override 
     public void onCreate(Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      setContentView(R.layout.activity_main); 
      Button test=(Button) findViewById(R.id.login); 
      un = (EditText) findViewById(R.id.et_un); 
      pw = (EditText) findViewById(R.id.et_pw); 


       test.setOnClickListener(new View.OnClickListener(){ 

        @Override

Answer 1

我猜你OnClickListener方法的问题，只是试试这个。

public class MainActivity extends Activity { 

    EditText un,pw; 
    TextView tv; 
    Button test; 
    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     Button test=(Button) findViewById(R.id.login); 
     un = (EditText) findViewById(R.id.et_un); 
     pw = (EditText) findViewById(R.id.et_pw); 


    test.setOnClickListener(new OnClickListener(){ 
    public void onClick(View v) { 
    final String NAMESPACE = "http://sparking.org/login"; 
    final String METHOD_NAME = "login"; 
    final String SOAP_ACTION = "http://sparking.org/login"; 
    final String URL = "http://localhost:63734/service.asmx"; 

    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 

    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 
    envelope.dotNet = true; 
    envelope.setOutputSoapObject(request); 
    HttpTransportSE transport = new HttpTransportSE(URL); 

    try { 
    transport.call(SOAP_ACTION, envelope); 
    SoapPrimitive resultstring = (SoapPrimitive)envelope.getResponse(); 

     } 

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

        } 
       }); 
} 
} 

Answer 2

这个错误是当你尝试通过你的主线程通过http进行通信。

声明“请求”对象之前，只需添加这些2号线：

StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build(); 
StrictMode.setThreadPolicy(policy); 

Answer 3

实际上，本地主机是模拟器本身在这里，因为代码仿真器中运行。所以你应该连接到10.0.2.2。详细内容见 Android Emulator Networking，不要忘了在清单文件中的网络权限
