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;
}

如果可以，选择JSON。Android自带完整的组织。json包

大约一年前，我读了这篇文章，试图弄清楚如何在Android上执行SOAP调用——使用HttpClient构建我自己的SOAP库的建议导致我为Android构建了自己的SOAP库:

IceSoap

基本上，它允许您构建通过简单的Java API发送的信封，然后自动将它们解析为通过XPath定义的对象……例如:

<Dictionary>
    <Id></Id>
    <Name></Name>
</Dictionary>

就变成:

@XMLObject("//Dictionary")
public class Dictionary {
    @XMLField("Id")
    private String id;

    @XMLField("Name")
    private String name;
}

我在我自己的项目中使用它，但我认为它可能会帮助其他人，所以我花了一些时间把它分离出来并记录下来。我真的很喜欢它，如果你的一些可怜的灵魂在谷歌“SOAP Android”时偶然发现这条线索，可以尝试一下，并得到一些好处。

Few months ago I was working with jax-ws web service in j2ee application, There we were using CXF wsdl2java to generate WS client stub from the WSDL file and with those client stubs we consumed the web services. Few weeks ago, when I was trying to consume the web service in the same way in android platform I couldn't, because the android jar has not all the "jax-ws" supporting classes in it. That time I didn't find any such tool ( if I wasn't failed to google efficiently) to meet my requirement --

从WSDL获取客户端存根。 并使用一些参数调用服务(java业务请求 对象)。 获取响应业务对象。

因此，我开发了自己的Android SOAP客户端生成工具。你需要遵循以下步骤:

从WSDL获取WS客户端存根，将其放入您的项目中。 例如，对于某些服务“ComplexOperationService”，实例化 Service，获取端点端口并调用服务方法，并从Web服务获取响应:

eg:

ComplexOperationService service = new ComplexOperationService( );
ComplexOperation port= service.getComplexOperationPort();    
SomeComplexRequest request = --Get some complex request----;    
SomeComplexResp resp = port.operate( request  );

您不需要关心服务类/请求/响应类或任何其他类以及方法，因为您知道它们都是从WSDL生成的。 当然，您不需要知道soap动作/信封/名称空间等等。就像我们开发人员一直做的那样调用这个方法。

不要忘记在您的项目中添加ksoap2.jar，并添加 AndroidManifest文件中的INTERNET权限

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.Bundle;
import android.widget.TextView;

public class WebserviceActivity extends Activity {

    private static final String NAMESPACE = "https://api.authorize.net/soap/v1/";
    private static final String URL ="https://apitest.authorize.net/soap/v1/Service.asmx?wsdl"; 
    private static final String SOAP_ACTION = "https://api.authorize.net/soap/v1/AuthenticateTest";
    private static final String METHOD_NAME = "AuthenticateTest";
    private TextView lblResult;


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

        lblResult = (TextView) findViewById(R.id.tv);

        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 
        request.addProperty("name","44vmMAYrhjfhj66fhJN");
        request.addProperty("transactionKey","9MDQ7fghjghjh53H48k7e7n");
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); 
        envelope.setOutputSoapObject(request);
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
        try {
            androidHttpTransport.call(SOAP_ACTION, envelope);

            //SoapPrimitive  resultsRequestSOAP = (SoapPrimitive) envelope.getResponse();
            // SoapPrimitive  resultsRequestSOAP = (SoapPrimitive) envelope.getResponse();
            SoapObject resultsRequestSOAP = (SoapObject) envelope.bodyIn;


            lblResult.setText(resultsRequestSOAP.toString());
            System.out.println("Response::"+resultsRequestSOAP.toString());


        } catch (Exception e) {
            System.out.println("Error"+e);
        }

    }
}

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
