kotlin - 如何检查当前时间是在kotlin中的某个时间之前还是之后

Question

我想检查当前时间(小时和分钟)是在某个时间之前还是之后，我该如何在 kotlin 中做到这一点

Answer 1

您可以使用 Calendar类:

val currentTime = Calendar.getInstance()
val timeToMatch = Calendar.getInstance()

timeToMatch[Calendar.HOUR_OF_DAY] = hourToMatch
timeToMatch[Calendar.MINUTE] = minuteToMatch

when {
    currentTime == timeToMatch -> // the times are equals
    currentTime < timeToMatch -> // currentTime is before timeToMatch
    currentTime > timeToMatch -> // currentTime is after timeToMatch
}
