import java.io.IOException;
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
import org.xmlpull.v1.XmlPullParserException;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.widget.EditText;
public class CallWs extends Activity {
final static String SERVICE_NS = "http://lee/";
final static String SERVICE_URL = "http://172.18.5.198/crazyit";
private EditText text1;
private EditText text2;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_call_ws);
text1 = (EditText) findViewById(R.id.text1);
text2 = (EditText) findViewById(R.id.text2);
//调用的方法
String methodName = "getUserList";
//创建HttpTransportSE传输对象
HttpTransportSE ht = new HttpTransportSE(SERVICE_URL);
ht.debug = true;
//使用SOAP1.1协议创建Envelop对象
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
//实例化SoapObject对象
SoapObject soapObject = new SoapObject(SERVICE_NS, methodName);
soapObject.addProperty("arg0","客户端参数:");
//将SoapObject对象设置为SoapSerializationEnvelope对象的传出SOAP消息
envelope.bodyOut = soapObject;
try {
//调用Web Service
ht.call(null, envelope);
if(envelope.getResponse() != null){
//获取服务器响应返回的SOAP消息
SoapObject result = (SoapObject) envelope.bodyIn;
//接下来是从SoapObject对象中解析响应数据的过程
SoapObject detail1 = (SoapObject) result.getProperty(0);
SoapObject detail2 = (SoapObject) result.getProperty(1);
StringBuilder person1 = new StringBuilder();
person1.append("用户名:");
person1.append(detail1.getProperty(3));
person1.append("\n密码");
person1.append(detail1.getProperty(0));
person1.append("\n身高");
person1.append(detail1.getProperty(1));
text1.setText(person1.toString());
StringBuilder person2 = new StringBuilder();
person2.append("用户名:");
person2.append(detail2.getProperty(3));
person2.append("\n密码");
person2.append(detail2.getProperty(0));
person2.append("\n身高");
person2.append(detail2.getProperty(1));
text2.setText(person2.toString());
}
} catch (IOException e) {
e.printStackTrace();
} catch (XmlPullParserException e) {
e.printStackTrace();
}
}
}
上面程序中的粗体字代码就代表了使用ksoap2-android来调用Web Service操作的关键的7个步骤。
不管远程Web Service提供的服务功能多么强大、业务实现多么复杂,对于Android客户端是完全透明的,Android只要送出相应的请求参数,服务器就会返回包含结果的SOAP消息。借助于Web Service这个桥梁,在Android应用中实现功能非常强大的应用-----反正具体的业务逻辑由Web Service服务器实现,Android客户端只要调用Web Service服务即可。
