快过年了，写个除夕倒计时软件

获取今日日期

星期获取

build.gradle中导入lunar三方库

dependencies {
   ...
    //lunar
    implementation libs.lunar
}

gradle/libs.versions.toml中

[versions]
...
lunar = "1.3.14"

[libraries]
...
lunar = { module = "cn.6tail:lunar", version.ref = "lunar" }

private Lunar lunar;
...
//当前时间
lunar = Lunar.fromDate(new Date());
//星期几
tvWeek.setText("星期" + lunar.getWeekInChinese());

天干地支、生肖、农历获取

//农历
tvNongli.setText(lunar.getYearInGanZhi() + "(" + lunar.getYearShengXiao() + ")年" + lunar.getMonthInChinese() + "月" + lunar.getDayInChinese());
