仿酒店入住日期选择器
最近公司要做个类似于酒店入住日期的选择器，就在网上找了一下，没有找到满足需求的，就在网上找个接近的改了一下，由于当初比较忙，忘记是参考那位大神的了，如果有知道的可以留言
首先先贴上demo的图片
一：DateBean
import java.util.Date;
public class DateBean {
//item类型
public static int item_type_day = 1;//日期item
public static int item_type_month = 2;//月份item
int itemType = 1;//默认是日期item
//item状态
public static int ITEM_STATE_BEGIN_DATE = 1;//开始日期
public static int ITEM_STATE_END_DATE = 2;//结束日期
public static int ITEM_STATE_SELECTED = 3;//选中状态
public static int ITEM_STATE_NORMAL = 4;//正常状态
public int itemState = ITEM_STATE_NORMAL;
Date date;//具体日期
String day;//一个月的某天
String monthStr;//月份
public int getItemState() {
return itemState;
}
public void setItemState(int itemState) {
this.itemState = itemState;
}
public int getItemType() {
return itemType;
}
public void setItemType(int itemType) {
this.itemType = itemType;
}
public String getMonthStr() {
return monthStr;
}
public void setMonthStr(String monthStr) {
this.monthStr = monthStr;
}
public static int getItem_type_month() {
return item_type_month;
}
public static void setItem_type_month(int item_type_month) {
DateBean.item_type_month = item_type_month;
}
public static int getItem_type_day() {
return item_type_day;
}
public static void setItem_type_day(int item_type_day) {
DateBean.item_type_day = item_type_day;
}
public String getDay() {
return day;
}
public void setDay(String day) {
this.day = day;
}
public Date getDate() {
return date;
}
public void setDate(Date date) {
this.date = date;
}
