像 Twitter 一样显示时间之前

Question

我DateUtils.getRelativeTimeSpanString()用于在发布帖子时显示。

它返回的字符串是这样的：1 minute ago，但我想要1 m或1 h等等（缩短并且没有之前）。

我可以用“h”替换“hour”或用“m”替换“minute”，但如果语言与英语不同，它将不起作用。这就是现在Twitter正在使用的。Twitter 的英文/西里尔文显示方式。

更新：我会接受@Bradley Wilson 的回答，尽管我会在这里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。谢谢你们：

    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(" ?.").printZeroNever().toFormatter();
        } else if (period.getMonths() != 0) {
            formatter = new PeriodFormatterBuilder().appendMonths().appendSuffix(" ?").printZeroNever().toFormatter();
        } else if (period.getWeeks() != 0) {
            formatter = new PeriodFormatterBuilder().appendWeeks().appendSuffix(" ????.").printZeroNever().toFormatter();
        } else if (period.getDays() != 0) {
            formatter = new PeriodFormatterBuilder().appendDays().appendSuffix(" ?").printZeroNever().toFormatter();
        } else if (period.getHours() != 0) {
            formatter = new PeriodFormatterBuilder().appendHours().appendSuffix(" ?").printZeroNever().toFormatter();
        } else if (period.getMinutes() != 0) {
            formatter = new PeriodFormatterBuilder().appendMinutes().appendSuffix(" ???").printZeroNever().toFormatter();
        } else {
            formatter = new PeriodFormatterBuilder().appendSeconds().appendSuffix(" ?").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"

您还可以传递国际化消息的语言环境：

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

正如评论中所指出的，Android 在android.text.format.DateUtils类中内置了此功能。

Answer 2

您可以使用JodaTime来实现此目的：

将依赖项添加到您的应用程序级Build.Gradle文件中，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输出即可time实现所需的“1m”

注意：您可以使用本地化来通过资源更改字符串。
