Android Joda-Time with Kotlin

Question

I am trying to create a function to check a given string time HH:mm is in range of another comparing to now.

Example: if the current hour is between 12:35 and 15:00 return true

But I always got false even if the current time is in range..

fun isTimeInRange(before: String, after: String): Boolean {
    val now = DateTime.now()
    val format = DateTimeFormat.forPattern("HH:mm")
    return now >= DateTime.parse(before, format) && now <= DateTime.parse(after, format)
}

Answer 1

You have to set before/after date to today's date. try this:

fun isTimeInRange(start: String, end: String): Boolean {
    val now = DateTime.now()
    val format = DateTimeFormat.forPattern("HH:mm")
    val startTime: LocalTime = format.parseLocalTime(start)
    val endTime: LocalTime = format.parseLocalTime(end)
    val timeZone = DateTimeZone.getDefault()
    val today: LocalDate = LocalDate.now(timeZone)
    val startMoment: DateTime = today.toLocalDateTime(startTime).toDateTime(timeZone)
    val endMoment: DateTime = today.toLocalDateTime(endTime).toDateTime(timeZone)
    return now.isAfter(startMoment) && now.isBefore(endMoment)
}
