这就是我目前所拥有的
Seconds = (60 - timeInMilliSeconds / 1000 % 60);
Minutes = (60 - ((timeInMilliSeconds / 1000) / 60) %60);
我觉得这是正确的。几个小时和几天应该像 -
Hours = ((((timeInMilliSeconds / 1000) / 60) / 60) % 24);
Days = ((((timeInMilliSeconds / 1000) / 60) / 60) / 24) % 24;
接着-
TextView.SetText("Time left:" + Days + ":" + Hours + ":" + Minutes + ":" + Seconds);
但我的时间和日子出来不正确
计算时间的一种简单方法是使用类似
long seconds = timeInMilliSeconds / 1000;
long minutes = seconds / 60;
long hours = minutes / 60;
long days = hours / 24;
String time = days + ":" + hours % 24 + ":" + minutes % 60 + ":" + seconds % 60;
如果您有超过 28 天的时间，这将有效，但如果您的时间为负数，则无效。
SimpleDateFormat 是您的朋友！（我今天才发现，太棒了。）
SimpleDateFormat formatter = new SimpleDateFormat("dd:HH:mm:ss", Locale.UK);
Date date = new Date(timeInMilliSeconds);
String result = formatter.format(date);

要在 android 中格式化经过/剩余时间，请使用android.text.format.DateUtils, 特别是getRelativeTimeSpanString和formatElapsedTime.
您还可以使用 joda-time API ( http://joda.org/joda-time/ )
“DateTimeFormat 类为Pattern(String) 提供了一个支持按模式格式化的方法。这些“基于模式”的格式化程序提供了与SimpleDateFormat 类似的方法。”
LocalDate date = LocalDate.now();
DateTimeFormatter fmt = DateTimeFormat.forPattern("d MMMM, yyyy");
String str = date.toString(fmt);
这是一个简单的JS函数
function simplifiedMilliseconds(milliseconds) {
const totalSeconds = parseInt(Math.floor(milliseconds / 1000));
const totalMinutes = parseInt(Math.floor(totalSeconds / 60));
const totalHours = parseInt(Math.floor(totalMinutes / 60));
const days = parseInt(Math.floor(totalHours / 24));
const seconds = parseInt(totalSeconds % 60);
const minutes = parseInt(totalMinutes % 60);
const hours = parseInt(totalHours % 24);
let time = '1s';
if (days > 0) {
time = `${days}d:${hours}h:${minutes}m:${seconds}s`;
} else if (hours > 0) {
time = `${hours}h:${minutes}m:${seconds}s`;
} else if (minutes > 0) {
time = `${minutes}m:${seconds}s`;
} else if (seconds > 0) {
time = `${seconds}s`;
}
return time;
}
我建议您使用java.time.Duration它以ISO-8601 标准为模型，并作为JSR-310 实现的一部分与Java-8一起引入。Java-9引入了一些更方便的方法。
import java.time.Duration;
public class Main {
public static void main(String[] args) {
// Given milliseconds e.g. milliseconds from the epoch
long millis = System.currentTimeMillis();
Duration duration = Duration.ofMillis(millis);
// Duration in default format
System.out.println(duration);
// Custom format
// ####################################Java-8####################################
String formattedElapsedTime = String.format("%d:%02d:%02d:%02d", duration.toDays(), duration.toHours() % 24,
duration.toMinutes() % 60, duration.toSeconds() % 60);
System.out.println("Duration (days:hours:min:seconds): " + formattedElapsedTime);
// ##############################################################################
// ####################################Java-9####################################
formattedElapsedTime = String.format("%d:%02d:%02d:%02d", duration.toDaysPart(), duration.toHoursPart(),
duration.toMinutesPart(), duration.toSecondsPart());
System.out.println("Duration (days:hours:min:seconds): " + formattedElapsedTime);
// ##############################################################################
}
}
输出：
PT448255H41M9.125S
Duration (days:hours:min:seconds): 18677:07:41:09
Duration (days:hours:min:seconds): 18677:07:41:09
注意：无论出于何种原因，如果您必须坚持使用 Java 6 或 Java 7，您可以使用ThreeTen-Backport，它将大部分java.time功能向后移植到 Java 6 和 7。如果您正在为 Android 项目工作并且您的 Android API 级别仍然不符合 Java-8，请检查Java 8+ APIs available through desugaring和How to use ThreeTenABP in Android Project。
java.util.concurrent.TimeUnit 救援：
long remainingMillis = 1076232425L; // Your value comes here.
long days = TimeUnit.MILLISECONDS.toDays(remainingMillis);
long daysMillis = TimeUnit.DAYS.toMillis(days);
long hours = TimeUnit.MILLISECONDS.toHours(remainingMillis - daysMillis);
long hoursMillis = TimeUnit.HOURS.toMillis(hours);
long minutes = TimeUnit.MILLISECONDS.toMinutes(remainingMillis - daysMillis - hoursMillis);
long minutesMillis = TimeUnit.MINUTES.toMillis(minutes);
long seconds = TimeUnit.MILLISECONDS.toSeconds(remainingMillis - daysMillis - hoursMillis - minutesMillis);
String resultString = days + " day(s) " + hours + " hour(s) " + minutes + " minute(s) " + seconds + " second(s)";
要解决您的问题，请尝试以下 java 类（具有不可变实例）
package adrjx.utils.time;
public class VRDecodedTimePeriodMillis
{
// instance data
private int theMillisecs = 0;
private int theSeconds = 0;
private int theMinutes = 0;
private int theHours = 0;
private int theDays = 0;
// init
public VRDecodedTimePeriodMillis (long aTimePeriodMillis)
{
long aSeconds = aTimePeriodMillis / 1000;
long aMinutes = aSeconds / 60;
long aHours = aMinutes / 60;
long aDays = aHours / 24;
this.theMillisecs = (int)(aTimePeriodMillis % 1000);
this.theSeconds = (int)(aSeconds % 60);
this.theMinutes = (int)(aMinutes % 60);
this.theHours = (int)(aHours % 24);
this.theDays = (int)(aDays);
// done
}
// accessors
public int getMillisecs() { return this.theMillisecs; }
public int getSeconds() { return this.theSeconds; }
public int getMinutes() { return this.theMinutes; }
public int getHours() { return this.theHours; }
public int getDays() { return this.theDays; }
}
这就是所有人...
