ListView CheckBox 仿百度小说界面UI
不废话，直接上代码
效果图：
主要代码：
CheckBean:
package baidu.example.ui;
public class CheckBean {
private int id;
private boolean isCheck;
private String name;
public int getId() {

}
public void setId(int id) {
this.id = id;
}
public boolean isCheck() {
return isCheck;
}
public void setCheck(boolean isCheck) {
this.isCheck = isCheck;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public CheckBean(int id, boolean isCheck, String name) {
super();
this.id = id;
this.isCheck = isCheck;
this.name = name;
}
public CheckBean(boolean isCheck, String name) {
super();
this.isCheck = isCheck;
this.name = name;
}
public CheckBean() {
super();
}
@Override
public String toString() {
return "CheckBean [id=" + id + ", isCheck=" + isCheck + ", name="

}
}
