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();
    }
}

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);

如果你可以使用JSON，有一个白皮书，一个视频和示例。使用PHP服务器和Android手机客户端开发应用程序服务中的代码。

我认为从Android应用程序调用SOAP Web服务会对你有很大帮助。

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。

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:

它支持相当复杂的web服务，并使用ksoap2。
