[Android][JAVA][kotlin] 获取各种语言的星期，月份,长月份，缩写月份

kotlin 写法

import java.text.DateFormatSymbols

    private fun loadTime() {
        val calendarInstance = Calendar.getInstance()
        val day = calendarInstance.get(Calendar.DAY_OF_MONTH)
        val month = calendarInstance.get(Calendar.MONTH)
        val weekday = calendarInstance.get(Calendar.DAY_OF_WEEK)
        binding!!.weekdaysTv.text = getWeekday(weekday)

        binding!!.monthAndDayTv.text = baseContext.resources.getString(
            R.string.month_and_day,
            getMonth(month),
            day.toString()
        )
    }

fun getMonth(month: Int): String? {
    return DateFormatSymbols().months[month - 1]
}
fun getWeekday(weekday: Int): String? {
    return DateFormatSymbols().shortWeekdays[weekday]
    //return DateFormatSymbols().weekdays[weekday]
}

kotlin 获取各种语言的星期，月份,长月份，缩写月份等，非常方便
这样在不同的语言下返回不同的日期，不需要自己关注翻译；
DateFormatSymbols().shortWeekdays[weekday] -------Sun
return DateFormatSymbols().weekdays[weekday] -----Sunday
