SoapConfig的代码我就不贴了，都是些地址配置，这个工具类有点通杀的感觉，那接下来就看看怎么用了。

public class LoginInTask extends AsyncTask<Void, Void, SoapObject> {

        String account, pwd;

        public LoginInTask(String account, String pwd) {
            this.account = account;
            this.pwd = pwd;
        }

        @Override
        protected SoapObject doInBackground(Void... params) {
            editor = preferences.edit();
            editor.putString("account", account);
            editor.apply();
            LinkedHashMap<String, Object> properties = new LinkedHashMap<>();
            properties.put("TrueName", account);
            properties.put("Pwd", pwd);
            return SoapUtil.postSoapRequest("LoginIn", properties);
        }

        @Override
        protected void onPostExecute(SoapObject soapObject) {
            if (soapObject.getPropertyCount() == 0) {
                failedLogin();
            } else {
                // 登陆成功
                succeedLogin();
            }
        }
    }

为什么要用LinkedHashMap而不是HashMap？
貌似wcf传输要按照一定的顺序，否则不通！

为什么使用AsyncTask而不是手动开启线程？
这样模块化了代码，清晰易懂，并且与界面交互较为简单。
