我希望从Android调用web服务有帮助。

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/

SOAP是一种不适合在Android(或一般的移动设备)上使用的技术，因为它需要处理/解析开销。REST服务是一种轻量级的解决方案，这就是我的建议。Android自带SAX解析器，使用起来相当简单。如果您绝对需要在移动设备上处理/解析SOAP，那么我为您感到遗憾，我能提供的最好的建议就是不要使用SOAP。

添加Soap库(ksoap2-android-assembly-3.2.0-jar-with-dependencies.jar)

            Map.Entry mapEntry = (Map.Entry) mapIterator1.next();

        ex.printStackTrace();

        return null;

}

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();
    }
}

我和KSOAP幽会过;我选择了一个相当简单的方法。

给定一个WSDL文件，为每个请求创建SOAP请求模板(例如:使用SOAP UI)，然后替换要在代码中传递的值。使用DefaultHttpClient实例将此数据发送到服务端点并获得响应流。使用XML Pull解析器解析响应流。
