Material Calendar 커스텀 버전 안 내리고 copyTo() 해결 solution 방법

https://github.com/prolificinteractive/material-calendarview

2022년 04월 03일 update 저처럼 시간 버리지 마세요

코드 내용
1. Material Calendar 주말 색상 바꾸기 (2가지 방법)
2. Material Calendar 월요일부터 시작하기 설정

1. Material Calendar를 이용하여 주말 색상 바꾸기 (짧은 2 번째 방법은 2 번에 같이)
첫 번째 코드는 MainActivity나 Fragment에 기술하면 됩니다
SaturdayDecorator, SundayDecorator이고 참고로 for구문은 의미가 없습니다......

materialCalendarView.addDecorators(
                new SundayDecorator(),
                new SaturdayDecorator());

package com.example.planner.UI.calendar;

import android.graphics.Color;
import android.text.style.ForegroundColorSpan;
import com.prolificinteractive.materialcalendarview.CalendarDay;
import com.prolificinteractive.materialcalendarview.DayViewDecorator;
import com.prolificinteractive.materialcalendarview.DayViewFacade;
import java.util.Calendar;

public class SaturdayDecorator implements DayViewDecorator {

    private final Calendar calendar = Calendar.getInstance();

    public SaturdayDecorator() {
    }

    @Override
    public boolean shouldDecorate(final CalendarDay day) {
        Calendar sDay = Calendar.getInstance(); // 시작일
        Calendar eDay = Calendar.getInstance(); // 끝일
        sDay.set(day.getYear(), day.getMonth()-1, day.getDay());
        eDay.set(day.getYear(), day.getMonth(), day.getDay());
        eDay.add(Calendar.DATE, -1);
        int START_DAY_OF_WEEK = sDay.get(Calendar.DAY_OF_WEEK);
        int END_DAY = eDay.get(Calendar.DATE);
        int C = 7 - START_DAY_OF_WEEK;
        sDay.set(day.getYear(), day.getMonth()-1+C, day.getDay());
        for(int i=1; i < END_DAY; i++) {
            if(i%7 == 0){
                day.getDay();
            }
        }
        return START_DAY_OF_WEEK == 7;
    }

    @Override
    public void decorate(DayViewFacade view) {
        view.addSpan(new ForegroundColorSpan(Color.BLUE));
    }
}

package com.example.planner.UI.calendar;

import android.graphics.Color;
import android.text.style.ForegroundColorSpan;
import com.prolificinteractive.materialcalendarview.CalendarDay;
import com.prolificinteractive.materialcalendarview.DayViewDecorator;
import com.prolificinteractive.materialcalendarview.DayViewFacade;
import java.util.Calendar;

public class SundayDecorator implements DayViewDecorator {

    private final Calendar calendar = Calendar.getInstance();
    public SundayDecorator() {
    }

    @Override
    public boolean shouldDecorate(final CalendarDay day) {
        Calendar sDay = Calendar.getInstance(); // 시작일
        Calendar eDay = Calendar.getInstance(); // 끝일
        sDay.set(day.getYear(), day.getMonth()-1, day.getDay());
        eDay.set(day.getYear(), day.getMonth(), day.getDay());
        eDay.add(Calendar.DATE, -1);
        int START_DAY_OF_WEEK = sDay.get(Calendar.DAY_OF_WEEK);
        int END_DAY = eDay.get(Calendar.DATE);
        int C = 1 - START_DAY_OF_WEEK;
        sDay.set(day.getYear(), day.getMonth()-1+C, day.getDay());
        for(int i=1; i < END_DAY; i++) {
            if(i%7 == 0){
                day.getDay();
            }
        }
        return START_DAY_OF_WEEK == 1;
    }

    @Override
    public void decorate(DayViewFacade view) {
        view.addSpan(new ForegroundColorSpan(Color.RED));
    }
}

 

2. 월요일부터 시작하기 설정
커스텀을 위해 라이브러리가 사용됩니다
안 되는 분들이 확인해야 할 것 

allprojects {
    repositories {
        google()
        mavenCentral()
        maven { url 'https://jitpack.io' }
    }
}

 // calendar
    implementation 'com.github.prolificinteractive:material-calendarview:2.0.1'
    implementation 'com.jakewharton.threetenabp:threetenabp:1.4.0'

setFirstDayOfWeek(DayOfWeek.of(Calendar.MONDAY))도 작동

materialCalendarView.state().edit()
                .setFirstDayOfWeek(DayOfWeek.MONDAY)
                .setCalendarDisplayMode(CalendarMode.MONTHS) // WEEKS
                .commit();

 

주말 색상 바꾸기 짧은 2 번째 방법
2 번대로 설정해야 작동합니다 

package com.example.planner.UI.calendar;

import android.graphics.Color;
import android.text.style.ForegroundColorSpan;
import com.prolificinteractive.materialcalendarview.CalendarDay;
import com.prolificinteractive.materialcalendarview.DayViewDecorator;
import com.prolificinteractive.materialcalendarview.DayViewFacade;
import org.threeten.bp.DayOfWeek;

public class SundayDecorator implements DayViewDecorator {
    public SundayDecorator() {
    }

    @Override
    public boolean shouldDecorate(final CalendarDay day) {
        final DayOfWeek weekDay = day.getDate().getDayOfWeek();
        return weekDay == DayOfWeek.SUNDAY;
    }
    
    @Override
    public void decorate(DayViewFacade view) {
        view.addSpan(new ForegroundColorSpan(Color.RED));
    }
}
