如何在Kotlin中将Firestore日期/时间戳转换为Date? [英] How do I convert a Firestore date/Timestamp to Date in Kotlin?

问题描述

我正在使用Firestore，但是当我从Firestore获得时间戳时，它会卡住.如何将 Timestamp(seconds = 1556006384，nanoseconds = 994000000)转换为Kotlin中的日期.

i'm working with firestore, and getting stuck when i get the timestamp from firestore. how i convert this Timestamp(seconds=1556006384, nanoseconds=994000000) to Date in kotlin.

我的最低SDK为21，因此下面的代码不起作用

my minimum SDK is 21 so the code below doesn't work

val timestamp = it["time"] as com.google.firebase.Timestamp
val milliseconds = timestamp.seconds * 1000 + timestamp.nanoseconds / 1000000
val tz = ZoneId.of("Asia/Jakarta (UTC+07:00)")
val localDateTime = LocalDateTime.ofInstant(Instant.ofEpochMilli(milliseconds), tz)

谢谢.

推荐答案

我正在使用以下代码:

val timestamp = it["time"] as com.google.firebase.Timestamp
val milliseconds = timestamp.seconds * 1000 + timestamp.nanoseconds / 1000000
val sdf = SimpleDateFormat("MM/dd/yyyy")
val netDate = Date(milliseconds)
val date = sdf.format(netDate).toString()
Log.d("TAG170", date)
