您可以使用Calendar该类：

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
}
