android - 如何在 Android Kotlin 中从 Date 获取小时数？

Question

我尝试从 Kotlin 中的 Date 数据类型获取小时，但出现此错误:

'getter for hours: Int' is deprecated. Deprecated in Java

还有我的代码:

val date:Date = ...
val hour = date.hours

这已被弃用并且未找到 getHours() ...

Answer 1

getHours() 已弃用。它替换为 Calendar.get(Calendar.HOUR_OF_DAY)

val date:Date = ... // your date
val cal = Calendar.getInstance()
cal.time = date
val hours = cal.get(Calendar.HOUR_OF_DAY)
