android/eclipse中的web服務

Question

我需要通過soap方法從android/eclipse中使用web服務。

即，我必須提供一個輸入並根據用戶輸入顯示來自Web服務的適當結果。如何操作？

Java類

public class Demo_webserviceActivity extends Activity 
{ 
/** Called when the activity is first created. */ 

    private static String NAMESPACE = "http://tempuri.org/"; 
    private static String METHOD_NAME = "GetName"; 
    private static String SOAP_ACTION = "http://tempuri.org/GetName"; 
    private static String URL = "http://122.248.240.105:234/Service1.asmx"; 

    Button btnFar; 
    EditText txtFar,txtCel; 


    @Override 
    public void onCreate(Bundle savedInstanceState) 
    { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 

    btnFar = (Button)findViewById(R.id.btnFar); 

    txtFar = (EditText)findViewById(R.id.txtFar); 
    txtCel = (EditText)findViewById(R.id.txtCel); 

    btnFar.setOnClickListener(new View.OnClickListener() 
    { 

    public void onClick(View v) 
    { 
    //Initialize soap request + add parameters 
    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);  

    //Use this to add parameters 
    request.addProperty("Fahrenheit",txtFar.getText().toString()); 

    //Declare the version of the SOAP request 
    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 

    envelope.setOutputSoapObject(request); 
    envelope.dotNet = true; 

    try 
    { 
     HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); 

     //this is the actual part that will call the webservice 
     androidHttpTransport.call(SOAP_ACTION, envelope); 

     // Get the SoapResult from the envelope body. 
     SoapObject result = (SoapObject)envelope.bodyIn; 

     if(result != null) 
     { 
      //Get the first property and change the label text 
      txtCel.setText(result.getProperty(0).toString()); 
     } 
     else 
     { 
      Toast.makeText(getApplicationContext(), "No Response",Toast.LENGTH_SHORT).show(); 
     } 
    } 
    catch (Exception e) 
    { 
     e.printStackTrace(); 
     } 
    } 
     }); 
    } 
} 

Web方法

public class GetName 
{ 
public String GetName(String Fahrenheit){ 
    return(Fahrenheit); 
} 
}

非常感謝

Answer 1

您應該使用SoapPrimitive results = (SoapPrimitive)envelope.getResponse();而不是SoapObject result = (SoapObject)envelope.bodyIn;因爲你的web服務返回string不object。

Answer 2

你會在正確的方向，即你在android寫的代碼是正確的。只要確保肥皂行動，方法，URl和命名空間你寫的是正確的。 如果您對這個或任何其他疑問有任何疑問，可以給我寫信。
