问题描述
2021-07-06T19:27:46.811+0530 -> 字符串形式的当前值
我想转换为 05/07/2021,06:45 am 这种格式
提前致谢
解决方法
使用java.time
:
import java.time.OffsetDateTime
import java.time.format.DateTimeFormatter
fun main() {
val input = "2021-07-06T19:27:46.811+0530"
// define a DateTimeFormatter for parsing your input
val parser = DateTimeFormatter.ofPattern("uuuu-MM-dd'T'HH:mm:ss.SSSx")
// and another one for formatting your output
val formatter = DateTimeFormatter.ofPattern("dd/MM/uuuu,hh:mm a")
// then parse the input to an OffsetDateTime using the parser
val converted: String = OffsetDateTime.parse(input,parser)
// and output the same time differently
.format(formatter)
// output the result
println(converted)
}
这段代码的输出是
06/07/2021,07:27 PM
好的,这并不完全是显示您想要的输出的示例的值,但我认为这完全与此处的格式有关。调整这些值需要更多的努力,包括对所需行为的简要描述。
,你可以这样做
Java:
SimpleDateFormat parserFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSZ",Locale.getDefault());
SimpleDateFormat convertFormat = new SimpleDateFormat("dd/MM/yyyy,hh:mm a",Locale.getDefault());
Date date = null;
try {
date = parserFormat.parse("2021-07-06T19:27:46.811+0530");
if (date != null) {
String formatedDate = convertFormat.format(date);
Log.e("formatted date",formatedDate);
}
} catch (ParseException e) {
e.printStackTrace();
Log.e("formatted date",e.getMessage());
}
科特林:
val parserFormat =
SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSSZ",Locale.getDefault())
val convertFormat =
SimpleDateFormat("dd/MM/yyyy,Locale.getDefault())
var date: Date? = null
try {
date = parserFormat.parse("2021-07-06T19:27:46.811+0530")
if (date != null) {
val formatedDate = convertFormat.format(date)
Log.e("formatted date",formatedDate)
}
} catch (e: ParseException) {
e.printStackTrace()
Log.e("formatted date",e.message!!)
}
,
你可以试试这个:
//Formats the date according to the given pattern
private fun dateFormat(date: Date,pattern: String = "yyyy-MM-dd"): String =
SimpleDateFormat(pattern,Locale.US).format(date)
如果你必须:
//string to date convert
fun convertStringDate(dateString: String): LocalDate {
val format = DateTimeFormatter.ISO_DATE
val tmpDate = LocalDate.parse("2019-12-10",format)
var parsedDate: LocalDate = tmpDate
try {
parsedDate = LocalDate.parse(dateString,format)
} catch (e: Exception) {
e.printStackTrace()
}
return parsedDate
}
