最近因为想自己做个简单的天气app，去网上搜了下关于天气的WebService，按http://www.cnblogs.com/ghj1976/archive/2011/04/26/2028904.html 上面的讲解学习，将天气的数据调用了出来，在安卓2.3可以显示，但是在4.2却显示不出数据，有点懵了！
下面show出代码
package com.example.weatherwebserviceapplication;
import java.io.UnsupportedEncodingException;
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
import android.os.Bundle;
import android.app.Activity;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;
public class WebService extends Activity
{
private static final String NAMESPACE = "http://WebXml.com.cn/";
private static String URL = "http://www.webxml.com.cn/webservices/weatherwebservice.asmx";
private static final String METHOD_NAME = "getWeatherbyCityName";
private static String SOAP_ACTION = "http://WebXml.com.cn/getWeatherbyCityName";
private String weatherToday;
private Button okButton;
private SoapObject detail;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
okButton = (Button) findViewById(R.id.button1);
okButton.setOnClickListener(new OnClickListener()
{
@Override
public void onClick(View v)
{
System.out.println("access button");
String city = "厦门";
getWeather(city);
}
});
}
public void getWeather(String cityName)
{
try
{
System.out.println("rpc------");
//指定webservice的命名空间和调用的方法名 SOAP协议
SoapObject rpc = new SoapObject(NAMESPACE, METHOD_NAME);
Log.e("rpc", rpc + "");
Log.e("cityName is ", cityName + "");
//设置调用方法的参数值
rpc.addProperty("theCityName", cityName);
//生成调用Webservice方法的SOAP请求信息
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);
//设置SOAPSoapSerializationEnvelope类的bodyOut属性
//该属性的值就是在第一步创建的SoapObject对象
envelope.bodyOut = rpc;
envelope.dotNet = true;
envelope.setOutputSoapObject(rpc);
HttpTransportSE ht = new HttpTransportSE(URL);
ht.debug = true;
//使用call方法调用WebService方法
ht.call(SOAP_ACTION, envelope);
//获得WebService方法的返回结果
detail = (SoapObject) envelope.getResponse();
Log.e("detail", detail + "");
Toast.makeText(WebService.this, detail.toString(),
Toast.LENGTH_LONG).show();
parseWeather(detail);
return;
}
catch (Exception e)
{
e.printStackTrace();
}
}
private void parseWeather(SoapObject detail)
throws UnsupportedEncodingException
{
String date = detail.getProperty(6).toString();
weatherToday = "今天：" + date.split(" ")[0];
weatherToday = weatherToday + "\n天气：" + date.split(" ")[1];
weatherToday = weatherToday + "\n气温："
+ detail.getProperty(5).toString();
weatherToday = weatherToday + "\n风力："
+ detail.getProperty(7).toString() + "\n";
Log.e("weatherToday is ", weatherToday + "");
Toast.makeText(WebService.this, weatherToday, Toast.LENGTH_LONG).show();
}
}奇怪的是，在安卓2.3可以显示出正常的天气数据，而安卓4.2却不行
在这里在看看logcat里面打印的日志：
安卓2.3
安卓4.2
今晚就先写到这里吧！明天继续找答案！预计是跟安卓系统版本内置的系统机制有关？安卓系统升级，肯定系统也改了不少地方吧！
