最近公司要做個(gè)類(lèi)似于酒店入住日期的選擇器，就在網(wǎng)上找了一下，沒(méi)有找到滿(mǎn)足需求的，就在網(wǎng)上找個(gè)接近的改了一下，由于當(dāng)初比較忙，忘記是參考那位大神的了，如果有知道的可以留言

首先先貼上demo的圖片

?

一：DateBean

import java.util.Date;public class DateBean {//item類(lèi)型public static int item_type_day = 1;//日期itempublic static int item_type_month = 2;//月份itemint itemType = 1;//默認(rèn)是日期item//item狀態(tài)public static int ITEM_STATE_BEGIN_DATE = 1;//開(kāi)始日期public static int ITEM_STATE_END_DATE = 2;//結(jié)束日期public static int ITEM_STATE_SELECTED = 3;//選中狀態(tài)public static int ITEM_STATE_NORMAL = 4;//正常狀態(tài)public int itemState = ITEM_STATE_NORMAL;Date date;//具體日期String day;//一個(gè)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;} }

二：MyItemD

import android.graphics.Canvas; import android.graphics.Color; import android.graphics.Paint; import android.support.annotation.NonNull; import android.support.v7.widget.RecyclerView; import android.view.View;public class MyItemD extends RecyclerView.ItemDecoration {Paint paint=new Paint();Paint colorPaint=new Paint();Paint linePaint=new Paint();public MyItemD(){paint.setColor(Color.parseColor("#ffffff"));paint.setStyle(Paint.Style.FILL);colorPaint.setColor(Color.parseColor("#ff6600"));colorPaint.setAntiAlias(true);linePaint.setAntiAlias(true);linePaint.setColor(Color.parseColor("#dddddd"));}@Overridepublic void onDrawOver(@NonNull Canvas c, @NonNull RecyclerView parent, @NonNull RecyclerView.State state) {super.onDrawOver(c, parent, state);if(parent.getChildCount()<=0){return;}//頭部的高度int height=50;final float scale = parent.getContext().getResources().getDisplayMetrics().density;height= (int) (height*scale+0.5f);//獲取第一個(gè)可見(jiàn)的view，通過(guò)此view獲取其對(duì)應(yīng)的月份CalendarList.CalendarAdapter a=(CalendarList.CalendarAdapter) parent.getAdapter();View fistView=parent.getChildAt(0);String text=a.data.get(parent.getChildAdapterPosition(fistView)).getMonthStr();String fistMonthStr="";int fistViewTop=0;//查找當(dāng)前可見(jiàn)的itemView中第一個(gè)月份類(lèi)型的itemfor(int i=0;i<parent.getChildCount();i++){View v=parent.getChildAt(i);if(2==parent.getChildViewHolder(v).getItemViewType()){fistMonthStr=a.data.get(parent.getChildAdapterPosition(v)).getMonthStr();fistViewTop=v.getTop();break;}}//計(jì)算偏移量int topOffset=0;if(!fistMonthStr.equals(text)&&fistViewTop<height){//前提是第一個(gè)可見(jiàn)的月份item不是當(dāng)前顯示的月份和距離的頂部的距離小于頭部的高度topOffset=height-fistViewTop;}int t=0-topOffset;//繪制頭部區(qū)域c.drawRect(parent.getLeft(),t,parent.getRight(),t+height,paint);colorPaint.setTextAlign(Paint.Align.CENTER);colorPaint.setTextSize(15*scale+0.5f);//繪制頭部月份文字c.drawText(text,parent.getRight()/2,(t+height)/2,colorPaint);//繪制分割線(xiàn) // if(fistViewTop!=height) { // linePaint.setStrokeWidth(scale * 0.5f + 0.5f); // c.drawLine(parent.getLeft(), t + height, parent.getRight(), t + height, linePaint); // }}}
