我希望从Android调用web服务有帮助。

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);

你可以看看WSClient++

如果可以，选择JSON。Android自带完整的组织。json包

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();
    }
}

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
