在MainActivity中用cb.setChecked(bean.isChecked());
為何出錯(cuò)？

package com.doop.commonadapter.bean;

/**

public class Bean {
??? //定義變量
??? private String title;
??? private String desc;
??? private String time;
??? private String phone;
??? private Boolean isChecked;

??? //記錄復(fù)選框是否選中

??? public Boolean getChecked() {
??????? return isChecked;
??? }

??? public void setChecked(Boolean checked) {
??????? isChecked = checked;
??? }

??? //添加構(gòu)造方法
??? //代碼→生成→構(gòu)造函數(shù)
??? public Bean() {
??? }

??? //添加屬性構(gòu)造方法
??? //代碼→生成→構(gòu)造函數(shù)（按住shift全選參數(shù)）
??? public Bean(String title, String desc, String time, String phone) {
??????? this.title = title;
??????? this.desc = desc;
??????? this.time = time;
??????? this.phone = phone;
??? }

??? // 生成get和set
//代碼→生成→構(gòu)造get和set（按住shift全選參數(shù)）

??? public String getTitle() {
??????? return title;
??? }

??? public Bean setTitle(String title) {
??????? this.title = title;
??????? return this;
??? }

??? public String getDesc() {
??????? return desc;
??? }

??? public Bean setDesc(String desc) {
??????? this.desc = desc;
??????? return this;
??? }

??? public String getTime() {
??????? return time;
??? }

??? public Bean setTime(String time) {
??????? this.time = time;
??????? return this;
??? }

??? public String getPhone() {
??????? return phone;
??? }

??? public Bean setPhone(String phone) {
??????? this.phone = phone;
??????? return this;
??? }
}

貼個(gè)代碼吧，仔細(xì)檢查可能漏寫了什么
