216.m1-JSON中2种不同的数据的解析

当一个JSON中有2种不同的数据，需要有不同的用途作为不同的Holder,这个时候需要分开解析

数据中title是一个单独的类型，需要单独显示，解析的过程如下

CategoryProtocol.java

package com.ldw.market.protocol;

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

import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;

import com.ldw.market.domain.CategoryInfo;

/*
 * 解析分类模块的数据
 */
public class CategoryProtocol extends BaseProtocol<List<CategoryInfo>> {

	@Override
	public List<CategoryInfo> parseJson(String json) {
		List<CategoryInfo> categoryInfos=new ArrayList<CategoryInfo>();
		try {
			JSONArray array=new JSONArray(json);
			for(int i=0;i<array.length();i++){
				JSONObject jsonObject = array.getJSONObject(i);
				String title=jsonObject.getString("title");
				//当前的对象是标题的时候，单独把title添加到集合中
				CategoryInfo categoryInfo=new CategoryInfo();
				categoryInfo.setTitle(title);
				categoryInfo.setIsTitle(true);
				categoryInfos.add(categoryInfo);
				
				//对象是其他的数据的时候单独保存
				JSONArray jsonArray = jsonObject.getJSONArray("infos");
				for(int j=0;j<jsonArray.length();j++){
					JSONObject jsonObject2 = jsonArray.getJSONObject(j);
					String url1=jsonObject2.getString("url1");
					String url2=jsonObject2.getString("url2");
					String url3=jsonObject2.getString("url3");
					String name1=jsonObject2.getString("name1");
					String name2=jsonObject2.getString("name2");
					String name3=jsonObject2.getString("name3");
					//最后一个参数判断数据是否是title
					CategoryInfo categoryInfo2=new CategoryInfo(title, url1, url2, url3, name1, name2, name3,false);
					categoryInfos.add(categoryInfo2);
				}
				
			}
			return categoryInfos;
			
		} catch (JSONException e) {
			e.printStackTrace();
			return null;
		}
	
	}

	@Override
	public String getKey() {
		return "category";
	}
}

JSON数据如下：
