在Android中讀取.NET Web Service響應

Question

從Android客戶端讀取.NET Web服務的響應時出現問題。 響應結構（例如）：

<xml> 
    <resaRef>400</resaRef> 
    <firstname>Amine</name> 
    <lastname>Touahria</lastname> 
</xml> 

這裏是我的代碼：

 import org.ksoap2.SoapEnvelope; 
     import org.ksoap2.serialization.PropertyInfo; 
     import org.ksoap2.serialization.SoapObject; 
     import org.ksoap2.serialization.SoapPrimitive; 
     import org.ksoap2.serialization.SoapSerializationEnvelope; 
     import org.ksoap2.transport.HttpTransportSE; 

     import android.app.Activity; 
     import android.os.AsyncTask; 
     import android.os.Bundle; 
     import android.view.View; 
     import android.view.View.OnClickListener; 
     import android.widget.Button; 
     import android.widget.EditText; 

     public class MainActivity extends Activity { 
      EditText ref; 
      Button call; 
      public final String NAMESPACE = "http://tempuri.org/"; 
      public final String URL = "http://192.168.0.100/hngwebsetup/HNGWeb.asmx"; 
      public final String SOAP_ACTION = "http://tempuri.org/GetResa"; 
      public final String METHOD_NAME = "GetResa"; 
      @Override 
      protected void onCreate(Bundle savedInstanceState) { 
       super.onCreate(savedInstanceState); 
       setContentView(R.layout.activity_main); 
       ref=(EditText)findViewById(R.id.ref_res); 


       call=(Button)findViewById(R.id.call_ws); 
       call.setOnClickListener(new OnClickListener() { 

        @Override 
        public void onClick(View v) { 
         AsyncCallWS task = new AsyncCallWS(); 
         task.execute(); 

        } 
       }); 

      } 
      public class AsyncCallWS extends AsyncTask<String, String,String>{ 

       protected String doInBackground(String... params) { 

        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 
        PropertyInfo pi =new PropertyInfo(); 
        pi.setName("resaRef"); 
        pi.setValue("400"); 
        pi.setType(String.class); 
        request.addProperty(pi); 

        /*PropertyInfo pi =new PropertyInfo(); 
        pi.setName("date"); 
        pi.setValue("20130601"); 
        pi.setType(String.class); 
        request.addProperty(pi);*/ 


        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 

        envelope.dotNet = true; 
        envelope.setOutputSoapObject(request); 
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL); 

        try{ 
         androidHttpTransport.call(SOAP_ACTION, envelope); 
         final SoapObject response = (SoapObject)envelope.getResponse(); 
         runOnUiThread(new Runnable() { 

          @Override 
          public void run() { 
           ref.setText(response.getProperty("nom").toString()); 


          } 
         }); 


        } 

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

        } 


        return null; 
       } 



      } 
     } 

我有這樣的例外：

什麼問題？

Answer 1

解決：
我只是顯示一個SoapObject然後

SoapObject obj=new SoapObject(); 
obj=(SoapObject) response.getProperty(0); 

ref.setText(obj.getPrimitiveProperty("Nom").toString()+obj.getPrimitiveProperty("DateDepart").toString()); 

Answer 2

我認爲這是關係到添加正確的庫在Eclipse的正確方法。這很可能會修復它：

1. 檢查您使用哪個JAR進行SOAP。
2. 轉到您的項目 - >屬性 - > Java構建路徑
3. 在標籤庫 - 確保你已經添加了JAR，你可以看到它。
4. 的標籤順序和導出 - 檢查Android的私人圖書館和Android依賴的盒子（也許也是JAR的框）

附：如果仍然沒有工作嘗試以下方法：

• 重新啓動Eclipse和清理項目（項目>清潔）

• 變化「排序和導出」項目的順序。在你做對了之前可能需要幾次嘗試。下一個應該工作（你在你的名單有可能是當然的不同）：

  1. SRC
  2. 根
  3. 谷歌的API
  4. Android的私家藏書
  5. 任何庫項目你有
  6. Android的依賴
  7. JAR文件
