我正在尝试将服务器时间(GMT+09:00)转换为本地时间(客户端的任何区域)。
我试过了java.time
。但是,它至少需要 minSdk API26。然后,我寻找替代方法
所以,我使用了 ThreeTenABP库。
我得到了这个例外。
java.lang.ExceptionInInitializerError
at org.threeten.bp.zone.ZoneRulesProvider.getRules(ZoneRulesProvider.java:121)
at org.threeten.bp.ZoneRegion.ofId(ZoneRegion.java:143)
at org.threeten.bp.ZoneId.of(ZoneId.java:358)
在onBindViewHolder()
适配器中。
val item = datas?.get(position)
AndroidThreeTen.init(context)
val checkedDate = item?.datetime
val serverTimeZone = ZoneId.of("Asia/Tokyo")
val serverFormatter = DateTimeFormatter.ofPattern("uuuu-MM-dd HH:mm:ss")
val clientTimeZone = ZoneId.systemDefault()
val serverDateTime = LocalDateTime.parse(checkedDate, serverFormatter).atZone(serverTimeZone)
val clientDateTime = serverDateTime.withZoneSameInstant(clientTimeZone)
另外,它似乎并不提供所有时区。如果我查看 ZoneId,我会在下面看到这些:
static {
Map<String, String> base = new HashMap();
base.put("ACT", "Australia/Darwin");
base.put("AET", "Australia/Sydney");
base.put("AGT", "America/Argentina/Buenos_Aires");
base.put("ART", "Africa/Cairo");
base.put("AST", "America/Anchorage");
base.put("BET", "America/Sao_Paulo");
base.put("BST", "Asia/Dhaka");
base.put("CAT", "Africa/Harare");
base.put("CNT", "America/St_Johns");
base.put("CST", "America/Chicago");
base.put("CTT", "Asia/Shanghai");
base.put("EAT", "Africa/Addis_Ababa");
base.put("ECT", "Europe/Paris");
base.put("IET", "America/Indiana/Indianapolis");
base.put("IST", "Asia/Kolkata");
base.put("JST", "Asia/Tokyo");
base.put("MIT", "Pacific/Apia");
base.put("NET", "Asia/Yerevan");
base.put("NST", "Pacific/Auckland");
base.put("PLT", "Asia/Karachi");
base.put("PNT", "America/Phoenix");
base.put("PRT", "America/Puerto_Rico");
base.put("PST", "America/Los_Angeles");
base.put("SST", "Pacific/Guadalcanal");
base.put("VST", "Asia/Ho_Chi_Minh");
base.put("EST", "-05:00");
base.put("MST", "-07:00");
base.put("HST", "-10:00");
SHORT_IDS = Collections.unmodifiableMap(base);
}
所以,当我在韩国首尔(“亚洲/首尔”)或地图不包括的其他地方时base
,我不知道它是否正常工作。如果我删除AndroidThreeTen.init(context)
,我会在下面得到这个:
