一、权限

<uses-permission android:name="android.permission.INTERNET"/>

二、实体domain

package cn.itcast.domain;

public class Video {
 private Integer id;
 private String title;
 private Integer time;
 
 public Video(){}
 
 public Video(Integer id, String title, Integer time) {
  this.id = id;
  this.title = title;
  this.time = time;
 }
 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 getTime() {
  return time;
 }
 public void setTime(Integer time) {
  this.time = time;
 }
 
}

三、编码

public static List<Video> getJSONLastVideos() throws Exception{
  List<Video> videos = new ArrayList<Video>();
  String path = "http://192.168.1.100:8080/videoweb/video/list.do?format=json";
  URL url = new URL(path);
  HttpURLConnection conn = (HttpURLConnection)url.openConnection();
  conn.setReadTimeout(5*1000);
  conn.setRequestMethod("GET");
  InputStream inStream = conn.getInputStream();
  byte[] data = StreamTool.readInputStream(inStream);
  String json = new String(data);
  JSONArray array = new JSONArray(json);
  for(int i=0 ; i < array.length() ; i++){
   JSONObject item = array.getJSONObject(i);
   int id = item.getInt("id");
   String title = item.getString("title");
   int timelength = item.getInt("timelength");
   videos.add(new Video(id, title, timelength));
  }
  return videos;
 }
