                startActivity(intent);

            } else {
                Toast.makeText(MiniSystemActivity.this, "用户或密码错误！",

            }
        }
    };

    public void call() {
        try {
            SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
            //request.addProperty("passonString", "Rajapandian"); //这个是传递参数的
            SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
                    SoapEnvelope.VER11);
            envelope.dotNet = true;
            envelope.setOutputSoapObject(request);
            HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
            androidHttpTransport.call(SOAP_ACTION, envelope);
            Object result = (Object) envelope.getResponse();
            tv.setText(result.toString()); 
        } catch (Exception e) {
            System.out.println(e.getMessage());
            tv.setText(e.getMessage());
        }
    }
}

---------------------------------以上 实现了 Android内通过Ksoap包的方法 调用了 .net webserivce中 helloworld 方法。

1.在ADT 虚拟机中 localhost/127.0.01是不行的。虚拟机中默认10.0.2.2为本地地址 所以我们在本地的.NET webservice 如果为localhost/webser/webtest.asmx 在Android模拟器中为10.0.2.2/webser/webtest/asmx.（该问题 亲自测试）

2.记得 在AndroidManifest.xml 加入 允许访问 Internet  <uses-permission android:name="android.permission.INTERNET" />
