json数据封装以及使用Gson将json数据封装到bean

public class NewBean {
	public NewBeanItem data;
	public String retcode;
	
	public class NewBeanItem{
		public String countcommenturl;
		//上拉加载
		public String more;
		public String title;
		
		public List<News> news;
		public List<Topic> topic;
		public List<Topnews> topnews;
	}
	
	/**
	 * 底部listview显示条目的javabean
	 * @author Administrator
	 *
	 */
	public class News{
		public String comment;
		public String commentlist;
		public String commenturl;
		//唯一性标志当前新闻条目
		public String id;
		//新闻列表的图片
		public String listimage;
		//时间
		public String pubdate;
		//新闻列表的标题文字	
		public String title;
		public String type;
		public String url;
		//该新闻是否已经读过的标志位
		public boolean isRead;
	}
	
	public class Topic{
		public String description;
		public String id;
		public String listimage;
		public String sort;
		public String title;
		public String url;
	}
	
	/**
	 * 顶部轮播图
	 * @author Administrator
	 *
	 */
	public class Topnews{
		public String comment;
		public String commentlist;
		public String commenturl;
		public String id;
		//轮播图图片链接地址
		public String topimage;
		//时间
		public String pubdate;
		//新闻列表的标题文字	
		public String title;
		public String type;
		public String url;
	}
}
