それ以降の時間を表示するための Android/Java 用の優れたライブラリの提案はありますか?

(例: 10 分前、5 日前)

Answer 2

DateUtils.getRelativeTimeSpanString()を確認してください。これは API レベル 3 から存在しています。

Answer 3

jquery timeago プラグインから

これにより、上記の回答よりも多くのオプションと形式が提供されます。

public static Date currentDate() {
    Calendar calendar = Calendar.getInstance();
    return calendar.getTime();
}

public static String getTimeAgo(Date date, Context ctx) {

    if(date == null) {
        return null;
    }

    long time = date.getTime();

    Date curDate = currentDate();
    long now = curDate.getTime();
    if (time > now || time <= 0) {
        return null;
    }

    int dim = getTimeDistanceInMinutes(time);

    String timeAgo = null;

    if (dim == 0) {
        timeAgo = ctx.getResources().getString(R.string.date_util_term_less) + " " +  ctx.getResources().getString(R.string.date_util_term_a) + " " + ctx.getResources().getString(R.string.date_util_unit_minute);
    } else if (dim == 1) {
        return "1 " + ctx.getResources().getString(R.string.date_util_unit_minute);
    } else if (dim >= 2 && dim <= 44) {
        timeAgo = dim + " " + ctx.getResources().getString(R.string.date_util_unit_minutes);
    } else if (dim >= 45 && dim <= 89) {
        timeAgo = ctx.getResources().getString(R.string.date_util_prefix_about) + " "+ctx.getResources().getString(R.string.date_util_term_an)+ " " + ctx.getResources().getString(R.string.date_util_unit_hour);
    } else if (dim >= 90 && dim <= 1439) {
        timeAgo = ctx.getResources().getString(R.string.date_util_prefix_about) + " " + (Math.round(dim / 60)) + " " + ctx.getResources().getString(R.string.date_util_unit_hours);
    } else if (dim >= 1440 && dim <= 2519) {
        timeAgo = "1 " + ctx.getResources().getString(R.string.date_util_unit_day);
    } else if (dim >= 2520 && dim <= 43199) {
        timeAgo = (Math.round(dim / 1440)) + " " + ctx.getResources().getString(R.string.date_util_unit_days);
    } else if (dim >= 43200 && dim <= 86399) {

    } else if (dim >= 86400 && dim <= 525599) {

    } else if (dim >= 525600 && dim <= 655199) {
        timeAgo = ctx.getResources().getString(R.string.date_util_prefix_about) + " "+ctx.getResources().getString(R.string.date_util_term_a)+ " " + ctx.getResources().getString(R.string.date_util_unit_year);
    } else if (dim >= 655200 && dim <= 914399) {
        timeAgo = ctx.getResources().getString(R.string.date_util_prefix_over) + " "+ctx.getResources().getString(R.string.date_util_term_a)+ " " + ctx.getResources().getString(R.string.date_util_unit_year);
    } else if (dim >= 914400 && dim <= 1051199) {

    } else {
        timeAgo = ctx.getResources().getString(R.string.date_util_prefix_about) + " " + (Math.round(dim / 525600)) + " " + ctx.getResources().getString(R.string.date_util_unit_years);
    }

    return timeAgo + " " + ctx.getResources().getString(R.string.date_util_suffix);
}

private static int getTimeDistanceInMinutes(long time) {
      long timeDistance = currentDate().getTime() - time;
      return Math.round((Math.abs(timeDistance) / 1000) / 60);
}

string.xml ファイルに次の文字列を追加します

<!-- Date Util -->
<string name="date_util_term_less">less than</string>
<string name="date_util_term_a">a</string>
<string name="date_util_term_an">an</string>

<string name="date_util_unit_second">second</string>
<string name="date_util_unit_seconds">seconds</string>
<string name="date_util_unit_minute">minute</string>
<string name="date_util_unit_minutes">minutes</string>
<string name="date_util_unit_hour">hour</string>
<string name="date_util_unit_hours">hours</string>
<string name="date_util_unit_day">day</string>
<string name="date_util_unit_days">days</string>
<string name="date_util_unit_month">month</string>
<string name="date_util_unit_months">months</string>
<string name="date_util_unit_year">year</string>
<string name="date_util_unit_years">years</string>

<string name="date_util_prefix_lt">less than a</string>
<string name="date_util_prefix_about">about</string>
<string name="date_util_prefix_over">over</string>
<string name="date_util_prefix_almost">almost</string>

<string name="date_util_suffix">ago</string>

Answer 4

メソッドで組み込みのDateUtilsクラスを使用できますgetRelative...()。

Answer 5

libray PrettyTime のような moment.js を使用することもできます。これにより、さらに翻訳されたコンテンツが得られます。http://www.ocpsoft.org/prettytime/

簡単な例:

PrettyTime p = new PrettyTime();
System.out.println(p.format(new Date()));
//prints: “moments from now”

System.out.println(p.format(new Date(System.currentTimeMillis() + 1000*60*10)));
//prints: “10 minutes from now”

@kaderudの回答で「n週間前」が必要な場合は、これを試してください。

Answer 7

Time4Jの Android バージョンである私のライブラリTime4Aを試すことができます。デモ：

Locale uk = Locale.UK;
TZID paris = EUROPE.PARIS; 
ChronoFormatter<Moment> f = 
    ChronoFormatter.ofMomentPattern("d. MMMM uuuu h:mm B", PatternType.CLDR, uk, paris);
PrettyTime pt = PrettyTime.of(uk);

// => examples for relative formats
Moment moment = f.parse("4. January 2016 5:45 in the afternoon");
System.out.println(pt.printRelative(moment, paris)); 
// output: 1 week ago

Moment now = SystemClock.currentMoment();
System.out.println(pt.printRelative(now, paris)); 
// output: now

Moment shortTimeAgo = now.minus(15, SI.SECONDS);
System.out.println(pt.printRelative(shortTimeAgo, paris)); 
// output: 15 seconds ago

TimeUnit precision = TimeUnit.DAYS;
System.out.println(pt.printRelative(shortTimeAgo, Timezone.of(paris), precision)); 
// output: today

// => examples for list formats     
Duration<?> duration = // this way for getting duration requires extra range-module
    MomentInterval.between(moment, now).getNominalDuration(
      Timezone.of(paris), 
      DAYS, HOURS, MINUTES);

System.out.println(pt.print(duration)); 
// output: 11 days, 1 hour and 26 minutes

System.out.println(pt.print(duration, TextWidth.ABBREVIATED)); 
// output: 11 days, 1 hr, 26 min

実際には、72 の言語(v3.18-2016c) がサポートされており、ローカライズされた複数形の規則(スラブ語またはアラビア語で重要) と3 つの異なるテキスト幅が含まれています。

年から秒までのすべての単位(またはリスト形式のミリ、マイクロ、ナノ) がサポートされています。

java.util.Dateタイムスタンプ (Unix エポック以降のミリ秒を表す) を time4j 型との間で変換または変換するには、次を使用できます。

java.util.Date d = TemporalType.JAVA_UTIL_DATE.from(moment);
long epochMillis = TemporalType.MILLIS_SINCE_UNIX.from(moment);
Moment m1 = TemporalType.JAVA_UTIL_DATE.translate(d);
Moment m2 = TemporalType.MILLIS_SINCE_UNIX.translate(epochMillis);

2019-06-06 からの更新:

gradle-dependency を使用した新しいバージョンの Time4A-4.4-2019a

dependencies {
    implementation group: 'net.time4j', name: 'time4j-android', version: '4.4-2019a'
}

94 の言語をサポートし、「次の日曜日」などの相対パターンも含まれるようになりました。

Answer 8

android-ago モジュールを使用できますhttps://github.com/curioustechizen/android-ago

XML にコンポーネントを追加する

<com.github.curioustechizen.ago.RelativeTimeTextView
android:id="@+id/timestamp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:relative_time_prefix="Completed "
android:layout_marginTop="@dimen/margin_primary" />

時間参照ビュー コードを設定する

RelativeTimeTextView v = (RelativeTimeTextView)findViewById(R.id.timestamp); //Or just use Butterknife!

v.setReferenceTime(new Date().getTime());

Answer 9

タイムスタンプ番号を入力するだけで、質問の回答が得られます。出力はあなたの場所に従って来ます。

public static String getTimeAgo(long timestamp) {

    Calendar cal = Calendar.getInstance();
    TimeZone tz = cal.getTimeZone();//get your local time zone.
    SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy hh:mm a");
    sdf.setTimeZone(tz);//set time zone.
    String localTime = sdf.format(new Date(timestamp * 1000));
    Date date = new Date();
    try {
        date = sdf.parse(localTime);//get local date
    } catch (ParseException e) {
        e.printStackTrace();
    }

    if(date == null) {
        return null;
    }

    long time = date.getTime();

    Date curDate = currentDate();
    long now = curDate.getTime();
    if (time > now || time <= 0) {
        return null;
    }

    int timeDIM = getTimeDistanceInMinutes(time);

    String timeAgo = null;

    if (timeDIM == 0) {
        timeAgo = "less than a minute";
    } else if (timeDIM == 1) {
        return "1 minute";
    } else if (timeDIM >= 2 && timeDIM <= 44) {
        timeAgo = timeDIM + " minutes";
    } else if (timeDIM >= 45 && timeDIM <= 89) {
        timeAgo = "about an hour";
    } else if (timeDIM >= 90 && timeDIM <= 1439) {

    } else if (timeDIM >= 914400 && timeDIM <= 1051199) {
        timeAgo = "almost 2 years";
    } else {
        timeAgo = "about " + (Math.round(timeDIM / 525600)) + " years";
    }

    return timeAgo + " ago";
}
