如果筛选结果,需要其他参数,或者bean中的展示字段不是tab_name,或者得到的筛选数据不满意,可以选择自定义筛选.
举个例子
如果想用自己的字段作为展示字段,只需要选择继承FilterTabBean,然后重写方法.设计之美,尽在其中.
首先看 顶层抽象Bean
/**
* 筛选bean的基类, 约束子类行为
* Created by chenchangjun on 17/7/26.
* 泛型T 泛型T 代表了 子类的类型.解决了 gosn Failed to invoke public **** with no args]
*/
public abstract class BaseFilterTabBean<T extends BaseFilterTabBean> {
/**
* 必须实现,涉及到adapter显示的值.要return list显示的字段.
* @return
*/
public abstract String getTab_name();
public abstract void setTab_name(String tab_name);
/**
* 如果有自己的子菜单,目前只有一级菜单,有二级菜单~
*
* @return
*/
public abstract List<T> getTabs();
public abstract void setTabs(List<T> tabs);
}
自定义自己数据beanMyFilterTabBean
public class MyFilterTabBean extends BaseFilterTabBean<MyFilterTabBean.MyChildFilterBean> {
//省略其他get set
/*情况1---比如,你需要如下字段*/
