最近项目中需要用到日历控件,1.需要给已经记录的日期添加圆环标记2.给当天日期添加背景3.给周末日期更改颜色4.日历添加农历,需求如上图所示:
GitHub的 material-calendarview star较高,而且项目最贴近以上需求

MaterialCalendarView项目开源地址:
https://github.com/prolificinteractive/material-calendarview

集成清单
1.添加compile'com.prolificinteractive:material-calendarview:1.4.2'
2.添加日历控件到布局中

功能展示
一.基础的功能和事件这里不做描述,可以到官方的demo中细看,下面贴出基础设置的xml和代码:

        calendarView = (MaterialCalendarView) findViewById(R.id.calendar_calendarView);
        year = TimeUtils.date2String(date, "yyyy");
        month = TimeUtils.date2String(date, "MM");
        //设置当前时间
        calendarView.setCurrentDate(date);
        calendarView
                .state()
                .edit()
                //设置一周的第一天是周日还是周一
                .setFirstDayOfWeek(Calendar.SUNDAY)
                //设置日期范围
                .setMinimumDate(CalendarDay.from(Integer.valueOf(year), Integer.parseInt(month) - 1, 1))
                .setMaximumDate(CalendarDay.from(Integer.valueOf(year), Integer.parseInt(month) - 1, 31))
                .setCalendarDisplayMode(CalendarMode.MONTHS)
                .commit();
        //设置周的文本
        calendarView.setWeekDayLabels(new String[]{"日", "一", "二", "三", "四", "五", "六"});
        //设置年月的title
        calendarView.setTitleFormatter(new TitleFormatter() {
            @Override
            public CharSequence format(CalendarDay day) {
                StringBuffer buffer = new StringBuffer();
                int yearOne = day.getYear();
                int monthOne = day.getMonth() + 1;
                buffer.append(yearOne).append("年").append(monthOne).append("月");
                return buffer;
            }
        });
        //添加修饰
        calendarView.addDecorators(new HighlightWeekendsDecorator(), new SameDayDecorator(), new LunarDecorator(year, month), new WorkdayDecorator());
        //日期点击事件
        calendarView.setOnDateChangedListener(this);

二.下面介绍MaterialCalendarView的强大自定义功能,addDecorators给特定日期添加特殊标记,首先要实现DayViewDecorator ,里面的shouldDecorate方法用于判断是否要对指定日期进行修饰,返回值boolean,decorate方法用于设置样式,里面运用了之前根本不了解的各种Span。
1.给周末日期设置特殊字体颜色:

/**

 */
public class HighlightWeekendsDecorator implements DayViewDecorator {

    private final Calendar calendar = Calendar.getInstance();

    @Override
    public boolean shouldDecorate(CalendarDay day) {
        day.copyTo(calendar);
        int weekDay = calendar.get(Calendar.DAY_OF_WEEK);
        return weekDay == Calendar.SATURDAY || weekDay == Calendar.SUNDAY;
    }

    @Override
    public void decorate(DayViewFacade view) {
        view.addSpan(new ForegroundColorSpan(Color.parseColor("#fd755c")));
    }
}

2.给日历当天进行圆背景修饰:

/**

 * 邮箱:[email protected]
 */
public class SameDayDecorator implements DayViewDecorator {
    @Override
    public boolean shouldDecorate(CalendarDay day) {
        Date date = new Date();
        String dateStr = TimeUtils.date2String(date, "yyyy-MM-dd");
        Date parse = TimeUtils.string2Date(dateStr, "yyyy-MM-dd");
        if (day.getDate().equals(parse)) {
            return true;
        }
        return false;
    }

    @Override
    public void decorate(DayViewFacade view) {
        view.addSpan(new CircleBackGroundSpan());
    }
}
/**
 * 作者:徐敏敏 on 2016/12/20 0020 14:27
 * 邮箱:[email protected]
 */
public class CircleBackGroundSpan implements LineBackgroundSpan {
    @Override
    public void drawBackground(Canvas c, Paint p, int left, int right, int top, int baseline, int bottom, CharSequence text, int start, int end, int lnum) {
        Paint paint = new Paint();
        paint.setColor(Color.parseColor("#def0ef"));
        c.drawCircle((right - left) / 2, (bottom - top) / 2 + dip2px(4), dip2px(18), paint);
    }
}

3.给日历每一天下方添加农历字体:

/**
 * 作者:徐敏敏 on 2016/12/20 0020 14:27
 * 邮箱:[email protected]
 */
public class LunarDecorator implements DayViewDecorator {
    private String year;
    private String month;

    public LunarDecorator(String year, String month) {
        this.year = year;
        this.month = month;
    }

    @Override
    public boolean shouldDecorate(CalendarDay day) {
        return true;
    }

    @Override
    public void decorate(DayViewFacade view) {
        view.addSpan(new LunarSpan(year,month));
    }
}
/**
 * 作者:徐敏敏 on 2016/12/20 0020 14:27
 * 邮箱:[email protected]
 */
public class LunarSpan implements LineBackgroundSpan {
    private String year;
    private String month;

    public LunarSpan(String year, String month) {
        this.year = year;
        this.month = month;
    }

    @Override
    public void drawBackground(Canvas c, Paint p, int left, int right, int top, int baseline, int bottom, CharSequence text, int start, int end, int lnum) {
        StringBuffer buffer = new StringBuffer();
        buffer.append(year).append("-").append(month).append("-").append(text);
        Date parse = TimeUtils.string2Date(buffer.toString(), "yyyy-MM-dd");
        Calendar calendar = Calendar.getInstance();
        calendar.setTime(parse);
        Lunar lunar = new Lunar(calendar);
        String chinaDayString = lunar.getChinaDayString();
        Paint paint = new Paint();
        paint.setTextSize(dip2px(10));
        paint.setColor(Color.parseColor("#cccccc"));
        c.drawText(chinaDayString, (right - left) / 2 - dip2px(10), (bottom - top) / 2 + dip2px(17), paint);
    }
}

4.对特定日期增加圆环修饰:

/**
 * 作者:徐敏敏 on 2016/12/20 0020 14:27
 * 邮箱:[email protected]
 */
public class EventDecorator implements DayViewDecorator {
    private List dates;

    public EventDecorator(List dates) {
        this.dates = dates;
    }

    @Override
    public boolean shouldDecorate(CalendarDay day) {
        return dates.contains(day.getDate());
    }

    @Override
    public void decorate(DayViewFacade view) {
        view.addSpan(new AnnulusSpan());
    }
}
/**
 * 作者:徐敏敏 on 2016/12/20 0020 14:27
 * 邮箱:[email protected]
 */
public class AnnulusSpan implements LineBackgroundSpan {
    @Override
    public void drawBackground(Canvas c, Paint p, int left, int right, int top, int baseline, int bottom, CharSequence text, int start, int end, int lnum) {
        Paint paint = new Paint();
        paint.setAntiAlias(true); //消除锯齿
        paint.setStyle(Paint.Style.STROKE);//绘制空心圆或 空心矩形
        int ringWidth = dip2px(1);//圆环宽度
        //绘制圆环
        paint.setColor(Color.parseColor("#00bcbe"));
        paint.setStrokeWidth(ringWidth);
        c.drawCircle((right - left) / 2, (bottom - top) / 2 + dip2px(4), dip2px(18), paint);
    }
}
