这是一个在android中使用SOAP web服务的工作示例。

**注意:***不要忘记在你的项目中添加ksoap2.jar，并在AndroidManifest文件中添加INTERNET权限*

public final String WSDL_TARGET_NAMESPACE = "http://tempuri.org/";
public final String METHOD_NAME = "FahrenheitToCelsius";
public final String PROPERTY_NAME = "Fahrenheit";
public final String SOAP_ACTION = "http://tempuri.org/FahrenheitToCelsius";
public final String SOAP_ADDRESS = "http://www.w3schools.com/webservices/tempconvert.asmx";


private class TestAsynk extends AsyncTask<String, Void, String> {

    @Override
    protected void onPostExecute(String result) {

        super.onPostExecute(result);
        Toast.makeText(getApplicationContext(),
                String.format("%.2f", Float.parseFloat(result)),
                Toast.LENGTH_SHORT).show();
    }

    @Override
    protected String doInBackground(String... params) {
        SoapObject request = new SoapObject(WSDL_TARGET_NAMESPACE,
                METHOD_NAME);
        request.addProperty(PROPERTY_NAME, params[0]);

        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                SoapEnvelope.VER11);
        envelope.dotNet = true;

        envelope.setOutputSoapObject(request);

        HttpTransportSE androidHttpTransport = new HttpTransportSE(
                SOAP_ADDRESS);
        Object response = null;
        try {

            androidHttpTransport.call(SOAP_ACTION, envelope);
            response = envelope.getResponse();
            Log.e("Object response", response.toString());

        } catch (Exception e) {
            e.printStackTrace();
        }
        return response.toString();
    }
}

你可以在http上使用特定的报头执行soap调用。 我没有像ksoap2这样的附加库就解决了这个问题 这里是从soap服务获得订单的实时代码

private static HashMap<String,String> mHeaders = new HashMap<>();

static {
    mHeaders.put("Accept-Encoding","gzip,deflate");
    mHeaders.put("Content-Type", "application/soap+xml");
    mHeaders.put("Host", "35.15.85.55:8080");
    mHeaders.put("Connection", "Keep-Alive");
    mHeaders.put("User-Agent","AndroidApp");
    mHeaders.put("Authorization","Basic Q2xpZW50NTkzMzppMjR3s2U="); // optional
}public final static InputStream receiveCurrentShipments(String stringUrlShipments)
{
    int status=0;
    String xmlstring= "<soap:Envelope xmlns:soap=\"http://www.w3.org/2003/05/soap-envelope\" xmlns:ser=\"http://35.15.85.55:8080/ServiceTransfer\">\n" +
            "   <soap:Header/>\n" +
            "   <soap:Body>\n" +
            "      <ser:GetAllOrdersOfShipment>\n" +
            "         <ser:CodeOfBranch></ser:CodeOfBranch>\n" +
            "      </ser:GetAllOrdersOfShipment>\n" +
            "   </soap:Body>\n" +
            "</soap:Envelope>";
    StringBuffer chaine = new StringBuffer("");

    HttpURLConnection connection = null;
    try {
        URL url = new URL(stringUrlShipments);
        connection = (HttpURLConnection) url.openConnection();
        connection.setRequestProperty("Content-Length", xmlstring.getBytes().length + "");
        connection.setRequestProperty("SOAPAction", "http://35.15.85.55:8080/ServiceTransfer/GetAllOrdersOfShipment");

        for(Map.Entry<String, String> entry : mHeaders.entrySet()) {
            String key = entry.getKey();
            String value = entry.getValue();
            connection.setRequestProperty(key,value);

        }

        connection.setRequestMethod("POST");
        connection.setDoInput(true);

        OutputStream outputStream = connection.getOutputStream();
        outputStream.write(xmlstring.getBytes("UTF-8"));
        outputStream.close();

        connection.connect();
        status = connection.getResponseCode();
    } catch (ProtocolException e) {
        e.printStackTrace();
    } catch (MalformedURLException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } finally {

        Log.i("HTTP Client", "HTTP status code : " + status);
    }

    InputStream inputStream = null;
    try {
        inputStream = connection.getInputStream();
    } catch (IOException e) {
        e.printStackTrace();
    }

    return inputStream;
}

请下载并添加SOAP库文件与您的项目 文件名称:ksoap2-android-assembly-3.4.0-jar-with-dependencies

清理应用程序，然后启动程序

下面是SOAP服务调用的代码

    String SOAP_ACTION = "YOUR_ACTION_NAME";
    String METHOD_NAME = "YOUR_METHOD_NAME";
    String NAMESPACE = "YOUR_NAME_SPACE";
    String URL = "YOUR_URL";
    SoapPrimitive resultString = null;

    try {
        SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);
        addPropertyForSOAP(Request);

        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("SOAP Result", "Result Celsius: " + resultString);
    } catch (Exception ex) {
        Log.e("SOAP Result", "Error: " + ex.getMessage());
    }
    if(resultString != null) {
        return resultString.toString();
    }
    else{
        return "error";
    }

结果可能是JSONObject或JSONArray或String

谢谢。

的确，由于开销过大，SOAP并不是与移动设备进行数据交换的最佳选择。但是，您可能会发现自己处于无法控制服务器输出格式的情况。

所以，如果你必须坚持使用SOAP，这里有一个为Android打补丁的kSOAP2库: http://code.google.com/p/ksoap2-android/

默认情况下，Android SDK中包含defaulthttpclient。这将使您连接到WSDL。

HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpGet httpGet = new HttpGet("http://www.example.com/" + URL);
HttpResponse response = httpClient.execute(httpGet, localContext);

对我来说，最简单的方法是使用好的工具来生成所有必需的类。我个人使用这个网站:

http://easywsdl.com/

它支持相当复杂的web服务，并使用ksoap2。
