爲android studio編寫SOAP API

我正在構建一個android應用程序，我希望它使用SOAP API進行請求和響應。我目前正在使用我得到的一個例子，但這個例子不起作用，我已經問過主機但他沒有回覆。所以這裏是代碼;爲android studio編寫SOAP API

Button bt; 
String TAG = "Response"; 
SoapPrimitive resultString; 
EditText celsius; 
String getCel; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 


    bt = (Button) findViewById(R.id.bt); 
    celsius = (EditText) findViewById(R.id.cel); 

    //add button listener 
    bt.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View arg0) { 

      getCel = celsius.getText().toString(); 
      AsyncCallWS task = new AsyncCallWS(); 
      task.execute(); 

     } 
    }); 
} 

private class AsyncCallWS extends AsyncTask<Void, Void, Void> { 

    @Override 
    protected void onPreExecute() { 
     Log.i(TAG, "onPreExecute"); 
    } 

    @Override 
    protected Void doInBackground(Void... params) { 
     Log.i(TAG, "doInBackground"); 
     Calculate(); 
     return null; 
    } 

    @Override 
    protected void onPostExecute(Void result) { 
     Log.i(TAG, "onPostExecute"); 
     Toast.makeText(MainActivity.this, "Response" + resultString.toString(), Toast.LENGTH_LONG).show(); 
    } 
} 


public void Calculate() { 
    String SOAP_ACTION = "http://www.w3schools.com/webservices/CelsiusToFahrenheit"; 
    String METHOD_NAME = "CelsiusToFahrenheit"; 
    String NAMESPACE = "http://www.w3schools.com/webservices/"; 
    String URL = "http://www.w3schools.com/webservices/tempconvert.asmx"; 

    try { 
     SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME); 
     Request.addProperty("Celsius", getCel); 

     SoapSerializationEnvelope soapEnvelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 
     soapEnvelope.dotNet = true; 
     soapEnvelope.setOutputSoapObject(Request); 

     HttpTransportSE transport = new HttpTransportSE(URL); 

     transport.call(SOAP_ACTION, soapEnvelope); 
     resultString = (SoapPrimitive) soapEnvelope.getResponse(); 

     Log.i(TAG, "Result Celsius: " + resultString); 
    } catch (Exception ex) { 
     Log.e(TAG, "Error: " + ex.getMessage()); 
    }

我收到它說一個錯誤：「）java.lang.String中org.ksoap2.serialization.SoapPrimitive.toString（」嘗試調用虛擬方法上一個空對象引用

Plz chk此網址：http://www.w3schools.com/webservices/tempconvert.asmx它不起作用 –

請提供您有哪些演示使用？ –

所以網站不工作。一切都好嗎？ –

嘗試這個代碼：

public class TabelActivity extends AppCompatActivity { 
private static String SOAP_ACTION = "http://tempuri.org/GetIDSSupportData"; 

private static String NAMESPACE = "http://tempuri.org/"; 
private static String METHOD_NAME = "GetIDSSupportData"; 
//change url here 
private static String URL = "http://166.62.119.183:8066/IDSSupportData.asmx"; 
String pksupportid,userid,username,email,subject,desc,entrydate,modatetime,issolved,imgsrc;

    envelope.setOutputSoapObject(request); 

    envelope.dotNet = true; 


    try {

     //this is the actual part that will call the webservice

清單檔案中的

：

<uses-permission android:name="android.permission.INTERNET" /> 
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

附加jar文件在你的lib folde [R ksoap2-機器人組裝-2.4-JAR-與-dependencies.jar在你的應用水平gradle這個文件

：

compile fileTree(include: '*.jar', dir: 'libs') 
compile files('libs/ksoap2-android-assembly-2.4-jar-with-dependencies.jar')

請改變你的代碼，並檢查它：

public void Calculate() { 
String SOAP_ACTION = "http://www.w3schools.com/xml/CelsiusToFahrenheit"; 
String METHOD_NAME = "CelsiusToFahrenheit"; 
String NAMESPACE = "http://www.w3schools.com/xml/"; 
String URL = "http://www.w3schools.com/xml/tempconvert.asmx"; 

try { 
    SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME); 
    Request.addProperty("Celsius", getCel); 

    SoapSerializationEnvelope soapEnvelope = new  

    SoapSerializationEnvelope(SoapEnvelope.VER11); 
    soapEnvelope.dotNet = true; 
    soapEnvelope.setOutputSoapObject(Request); 

    HttpTransportSE transport = new HttpTransportSE(URL); 

    transport.call(SOAP_ACTION, soapEnvelope); 
    resultString = (SoapPrimitive) soapEnvelope.getResponse(); 

    Log.i(TAG, "Result Celsius: " + resultString); 
} catch (Exception ex) { 
    Log.e(TAG, "Error: " + ex.getMessage()); 
}

，但正如你所看到的，我試圖鏈接一個按鈕，這樣當點擊它時可以做SOAP Api –

@RileyB plz檢查我編輯的答案 –

@RileyB讓我知道它是否工作或不是 –

您的URL錯誤，它們已被更改。試試這個：

String SOAP_ACTION = "http://www.w3schools.com/xml/CelsiusToFahrenheit"; 
    String METHOD_NAME = "CelsiusToFahrenheit"; 
    String NAMESPACE = "http://www.w3schools.com/xml/"; 
    String URL = "http://www.w3schools.com/xml/tempconvert.asmx";

我希望它適合你。讓我知道
