像推特一样显示之前的时间

Question

我正在使用

DateUtils.getRelativeTimeSpanString()

在发帖时显示。

它返回的字符串是这样的：1 分钟前，但我想是 1 m 或 1 h 等等（缩短且没有之前）。

我可以将“小时”替换为“h”或将“分钟”替换为“m”，但如果语言与英语不同，则无法使用。

Twitter

现在用的就是这个。 English/Cyrillic 推特显示方式

更新：我会接受@Bradley Wilson 的回答，尽管我会在此处添加更清洁的解决方案（再次使用 JodaTime 包）。此外，其余的答案也可以修改为相同的结果，因此他们值得投票。谢谢大家：

    DateTime postMaded = new DateTime(your previous date);
    DateTime nowUpdate = new DateTime();

    Period period = new Period(postMaded, nowUpdate);

    PeriodFormatter formatter;

    Locale current = ConverterMethods.getCurrentLocale();

    if (current.getLanguage().contentEquals(any Cyrillic language )) {

        if (period.getYears() != 0) {
            formatter = new PeriodFormatterBuilder().appendYears().appendSuffix(" г.").printZeroNever().toFormatter();
        } else if (period.getMonths() != 0) {
            formatter = new PeriodFormatterBuilder().appendMonths().appendSuffix(" м").printZeroNever().toFormatter();
        } else if (period.getWeeks() != 0) {
            formatter = new PeriodFormatterBuilder().appendWeeks().appendSuffix(" седм.").printZeroNever().toFormatter();
        } else if (period.getDays() != 0) {
            formatter = new PeriodFormatterBuilder().appendDays().appendSuffix(" д").printZeroNever().toFormatter();
        } else if (period.getHours() != 0) {
            formatter = new PeriodFormatterBuilder().appendHours().appendSuffix(" ч").printZeroNever().toFormatter();
        } else if (period.getMinutes() != 0) {
            formatter = new PeriodFormatterBuilder().appendMinutes().appendSuffix(" мин").printZeroNever().toFormatter();
        } else {
            formatter = new PeriodFormatterBuilder().appendSeconds().appendSuffix(" с").printZeroNever().toFormatter();
        }

    } else {

        if (period.getYears() != 0) {
            formatter = new PeriodFormatterBuilder().appendYears().appendSuffix(" y").printZeroNever().toFormatter();
        } else if (period.getMonths() != 0) {
            formatter = new PeriodFormatterBuilder().appendMonths().appendSuffix(" mon").printZeroNever().toFormatter();
        } else if (period.getWeeks() != 0) {
            formatter = new PeriodFormatterBuilder().appendWeeks().appendSuffix(" w").printZeroNever().toFormatter();
        } else if (period.getDays() != 0) {
            formatter = new PeriodFormatterBuilder().appendDays().appendSuffix(" d").printZeroNever().toFormatter();
        } else if (period.getHours() != 0) {
            formatter = new PeriodFormatterBuilder().appendHours().appendSuffix(" h").printZeroNever().toFormatter();
        } else if (period.getMinutes() != 0) {
            formatter = new PeriodFormatterBuilder().appendMinutes().appendSuffix(" m").printZeroNever().toFormatter();
        } else {
            formatter = new PeriodFormatterBuilder().appendSeconds().appendSuffix(" s").printZeroNever().toFormatter();

    }

Answer 1

看看 PrettyTime 库。

使用起来非常简单：

import org.ocpsoft.prettytime.PrettyTime

PrettyTime p = new PrettyTime();
System.out.println(p.format(new Date()));
// prints "moments ago"

或者也可以为国际化消息传入语言环境：

PrettyTime p = new PrettyTime(new Locale("fr"));
System.out.println(p.format(new Date()));
// prints "à l'instant"

如评论中所述，Android 已将此功能内置到

android.text.format.DateUtils

类中。

Answer 2

你可以使用这个功能来做到这一点

  public static String getTimeAgo(long time) {
     if (time < 1000000000000L) {
     // if timestamp given in seconds, convert to millis
     time *= 1000;
  }

  long now = System.currentTimeMillis();
  if (time > now || time <= 0) {
     return null;
  }

  // TODO: localize
  final long diff = now - time;
  if (diff < MINUTE_MILLIS) {
     return "just now";
  } else if (diff < 2 * MINUTE_MILLIS) {
     return "a minute ago";
  } else if (diff < 50 * MINUTE_MILLIS) {
     return diff / MINUTE_MILLIS + " min ago";
  } else if (diff < 90 * MINUTE_MILLIS) {
     return "an hour ago";
  } else if (diff < 24 * HOUR_MILLIS) {
     return diff / HOUR_MILLIS + " hours ago";
  } else if (diff < 48 * HOUR_MILLIS) {
     return "yesterday";
  } else {
     return diff / DAY_MILLIS + " days ago";
  }
 }

Answer 3

您可以使用 JodaTime 来实现这一点：

将依赖项添加到您的应用程序级别

Build.Gradle

文件，如下所示：

compile 'net.danlew:android.joda:2.9.4.1'

然后你就可以简单地实现这个功能。

private String time = "Just Now";

private String how_long_ago(String created_at) {
        DateTime sinceGraduation = new DateTime(created_at, GregorianChronology.getInstance());
        DateTime currentDate = new DateTime(); //current date

        Months diffInMonths = Months.monthsBetween(sinceGraduation, currentDate);
        Days diffInDays = Days.daysBetween(sinceGraduation, currentDate);
        Hours diffInHours = Hours.hoursBetween(sinceGraduation, currentDate);
        Minutes diffInMinutes = Minutes.minutesBetween(sinceGraduation, currentDate);
        Seconds seconds = Seconds.secondsBetween(sinceGraduation, currentDate);

        Log.d("since grad", "before if " + sinceGraduation);
        if (diffInDays.isGreaterThan(Days.days(31))) {
            time = diffInMonths.getMonths() + " months ago";
            if (diffInMonths.getMonths() == 1) {
                time = diffInMonths.getMonths() + " month ago";
            } else {
                time = diffInMonths.getMonths() + " months ago";
            }
            return time;
        } else if (diffInHours.isGreaterThan(Hours.hours(24))) {
            if (diffInDays.getDays() == 1) {
                time = diffInDays.getDays() + " day ago";
            } else {
                time = diffInDays.getDays() + " days ago";
            }
            return time;
        } else if (diffInMinutes.isGreaterThan(Minutes.minutes(60))) {
            if (diffInHours.getHours() == 1) {
                time = diffInHours.getHours() + " hour ago";
            } else {
                time = diffInHours.getHours() + " hours ago";
            }
            return time;
        } else if (seconds.isGreaterThan(Seconds.seconds(60))) {
            if (diffInMinutes.getMinutes() == 1) {
                time = diffInMinutes.getMinutes() + " minute ago";
            } else {
                time = diffInMinutes.getMinutes() + " minutes ago";
            }
            return time;
        } else if (seconds.isLessThan(Seconds.seconds(60))) {
            return time;
        }
        Log.d("since grad", "" + sinceGraduation);
        return time;
    }

只需更改

String

输出

time

即可达到所需的'1m'

注意：您可以使用本地化通过您的资源更改字符串。

Answer 4

使用我的图书馆 Time4A 会像您在问题中指定的那样工作：

打印相对时间（with ago-word）

    PlainTimestamp now = PlainTimestamp.nowInSystemTime();
    PlainTimestamp earlier = now.minus(1, ClockUnit.MINUTES);
    Moment past = earlier.inStdTimezone();
    Locale russian = new Locale("ru");

    PrettyTime.of(Locale.ENGLISH).printRelativeInStdTimezone(past);
    // output: 1 minute ago

    PrettyTime.of(Locale.ENGLISH)
       .withShortStyle().printRelativeInStdTimezone(past);
    // output: 1 min. ago

    PrettyTime.of(russian).printRelativeInStdTimezone(past);
    // output: 1 минуту назад

    PrettyTime.of(russian).withShortStyle().printRelativeInStdTimezone(past);
    // output: 1 мин. назад

打印没有前词的平面时间

    IsoUnit days = CalendarUnit.DAYS;
    IsoUnit hours = ClockUnit.HOURS;
    IsoUnit minutes = ClockUnit.MINUTES;
    net.time4j.Duration<IsoUnit> d =
        Duration.in(Timezone.ofSystem(), days, hours, minutes)
            .between(earlier, now);

    PrettyTime.of(Locale.ENGLISH).print(d, TextWidth.WIDE);
    // output: 1 minute

    PrettyTime.of(Locale.ENGLISH).print(d, TextWidth.ABBREVIATED);
    // output: 1 min

    PrettyTime.of(Locale.ENGLISH).print(d, TextWidth.NARROW);
    // output: 1m

    PrettyTime.of(russian).print(d, TextWidth.WIDE);
    // output: 1 минута

    PrettyTime.of(russian).print(d, TextWidth.ABBREVIATED);
    // output: 1 мин

    PrettyTime.of(russian).print(d, TextWidth.NARROW);
    // output: 1 мин

最新的库版本使用了CLDR-repository v30.0.2的数据（来自Unicode-consortium，实际支持80种语言）。如有必要，您可能希望通过定义要与 Time4A 一起分发的自己的资产来更改文本资源（然后覆盖默认资产）。
