数据太长,不适合观看,可以尝试下这个链接http://api.qiuduoduo.cn/sns/categories/all?hasGroups=true
由上图可以看出来categoryGroupsMap对象下面的是一个1,2,3,4,5动态变化的Key对象。面对这种Key我可以采用下面这种解决方案
package com.wj.baseutils.bean;
import java.util.List;
import java.util.Map;
/**
* Created by wj on 2018/2/5.
*/
public class TribeCategoryBean {
public int ret;
public DataBean data;
public long serverTime;
public static class DataBean {
// public CategoryGroupsMapBean categoryGroupsMap;
public List categories;
public Map> categoryGroupsMap;
public static class CategoryGroupsMapBean {
public static class ObjBean {
public int id;
public String name;
public String icon;
public String cover;
public int groupType;
public int teamId;
}
}
public static class CategoriesBean {
public int id;
public String name;
}
}
}
从上面代码中,我们可以看出CategoryGroupsMapBean我们定义成了一个Map集合,Map的String类型的Key正好对应动态变化的Key。
下面获取Map对象,并且for循环遍历,获取key从Map中获取我们想要的Value,也就是我们需要的对象~~~~~~~~
@Override
public void setCategory(TribeCategoryBean result) {
typeList.clear();
list.clear();
if (result != null && result.data != null
&& result.data.categories != null &&
result.data.categories.size() > 0) {
typeList.addAll(result.data.categories);
typeAdapter.notifyDataSetChanged();
Map> categoryGroupsMap =
result.data.categoryGroupsMap;
for (String key : categoryGroupsMap.keySet()) {
List objBeans = categoryGroupsMap.get(key);
}
}
}
