Android中获取SQL Server中的数据

1、创建一般处理程序

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Services;
using System.Xml;

 

namespace service
{
    ///

    /// $codebehindclassname$ 的摘要说明
    ///

    [WebService(Namespace = "http://tempuri.org/")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    public class MobileService : IHttpHandler
    {
       
        public void ProcessRequest(HttpContext context)
        {
            context.Response.ContentType = "text/plain";

            XmlDocument doc = new XmlDocument();
            XmlDeclaration dec = doc.CreateXmlDeclaration("1.0", "utf-8", null);
            doc.AppendChild(dec);
            //创建一个根节点（一级）
            XmlElement root = doc.CreateElement("First");
            doc.AppendChild(root);
            //创建节点（二级）
            XmlNode node = doc.CreateElement("Seconde");
            //创建节点（三级）
            XmlElement element1 = doc.CreateElement("Third1");
            element1.SetAttribute("Name", name);
            element1.SetAttribute("ID", "665");
            element1.InnerText = "Sam Comment";
            node.AppendChild(element1);

            XmlElement element2 = doc.CreateElement("Third2");
            element2.SetAttribute("Name", "Round");
            element2.SetAttribute("ID", "678");
            element2.InnerText = "Round Comment";
            node.AppendChild(element2);

            root.AppendChild(node);

            context.Response.Write(doc.InnerXml);
        }

        public bool IsReusable
        {
            get
            {
                return true;
            }
        }
    }
}

2、Java程序

package cn.itcast.service;

import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.URL;
import java.util.ArrayList;
import java.util.List;

import org.json.JSONArray;
import org.json.JSONObject;
import org.xmlpull.v1.XmlPullParser;

import android.util.Xml;

import cn.itcast.domain.Video;
import cn.itcast.utils.StreamTool;

public class VideoService {
 /**
  * 从服务器获取最新的视频资讯
  * @return
  * @throws Throwable
  */
 public static List

 private static List

3、

package cn.itcast.domain;
/**
 * 视频资讯
 */
public class Video {
 private Integer id;
 private String title;
 private Integer timelength;
 
 public Video(){}
 
 public Video(Integer id, String title, Integer timelength) {
  this.id = id;
  this.title = title;
  this.timelength = timelength;
 }
 public Integer getId() {
  return id;
 }
 public void setId(Integer id) {
  this.id = id;
 }
 public String getTitle() {
  return title;
 }
 public void setTitle(String title) {
  this.title = title;
 }
 public Integer getTimelength() {
  return timelength;
 }
 public void setTimelength(Integer timelength) {
  this.timelength = timelength;
 }

 @Override
 public String toString() {
  return "Video [id=" + id + ", timelength=" + timelength + ", title="
    + title + "]";
 }
 
}

4、

package cn.itcast.utils;

import java.io.ByteArrayOutputStream;
import java.io.InputStream;

public class StreamTool {
 /**
  * 从输入流中读取数据
  * @param inStream
  * @return
  * @throws Exception
  */
 public static byte[] readInputStream(InputStream inStream) throws Exception{
  ByteArrayOutputStream outStream = new ByteArrayOutputStream();
  byte[] buffer = new byte[1024];
  int len = 0;
  while( (len = inStream.read(buffer)) !=-1 ){
   outStream.write(buffer, 0, len);
  }
  byte[] data = outStream.toByteArray();//网页的二进制数据
  outStream.close();
  inStream.close();
  return data;
 }
}

5、

package cn.itcast.videonews;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;

import cn.itcast.domain.Video;
import cn.itcast.service.VideoService;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.widget.ListView;
import android.widget.SimpleAdapter;
import android.widget.Toast;

public class MainActivity extends Activity {
    private static final String TAG = "MainActivity";
   
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
       
        try {
   List

6、

package cn.itcast.videonews;

import java.util.List;

import cn.itcast.domain.Video;
import cn.itcast.service.VideoService;
import android.test.AndroidTestCase;
import android.util.Log;

public class VideoServiceTest extends AndroidTestCase {
 private static final String TAG = "VideoServiceTest";
 
 public void testGetLastVideos() throws Throwable{
  List
