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。

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。

你可以看看WSClient++

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。

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);

要从移动设备(尤其是Android手机)调用web服务，我使用了一种非常简单的方法。我没有使用任何web服务客户端API试图调用web服务。我打电话的方法如下。

Create a simple HTTP connection by using the Java standard API HttpURLConnection. Form a SOAP request. (You can make help of SOAPUI to make a SOAP request.) Set doOutPut flag as true. Set HTTP header values like content-length, Content type, and User-agent. Do not forget to set Content-length value as it is a mandatory. Write entire the SOAP request to the output stream. Call the method to make a connection and receive the response (In my case I used getResonseCode). If your received response code as It means you are succeeded to call web service. Now take an input stream on the same HTTP connection and receive the string object. This string object is a SOAP response. If the response code is other than 200 then take a ErrorInput stream on same HTTPobject and receive the error if any. Parse the received response using SAXParser (in my case) or DOMParaser or any other parsing mechanism.

我已经在Android手机上实现了这个过程，并且它正在成功运行。我能够解析响应，即使它超过700 KB。
