1：要在android上呼叫，我們首先下載ksoap2-android jar包，丟到lib包下，新增依賴

2：接著我們提取出一個請求的工具類SoapConfig

3.在ViewModel中呼叫請求

 4 解析請求WebService返回SoapObject 資料解析

try {
                    SoapSerializationEnvelope envelope = (SoapSerializationEnvelope) o;
                    Object ob = envelope.bodyIn;
                    SoapObject soapObject = (SoapObject) envelope.getResponse();
                    SoapObject str = (SoapObject) soapObject.getProperty(0);
                    SoapObject st1 = (SoapObject) soapObject.getProperty(1);
                    SoapObject str2 = (SoapObject) st1.getProperty(0);
                    List<SimpleType> lists = new ArrayList<>();


                    for (int i = 0; i < str2.getPropertyCount(); i++) {
                        SoapObject soapObject1 = (SoapObject) str2.getProperty(i);
                        lists.add(new SimpleType(Integer.parseInt(soapObject1.getPropertyAsString("RegionID")), soapObject1.getPropertyAsString("RegionName")));
                    }
                    Logger.d(String.valueOf(lists.size()));
                } catch (SoapFault soapFault) {
                    soapFault.printStackTrace();
                }
