androidで時間を「時間前」に変換する方法
私のサーバー。それは時間を返します：
"2016-01-24T16:00:00.000Z"
が欲しいです
1：文字列に変換します。
2：サーバーからロードするときに「時間前」を表示したい。
お願いします。助けて！
主に3つの方法があります。
a）SimpleDateFormatおよび DateUtils を使用した組み込みオプション
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
sdf.setTimeZone(TimeZone.getTimeZone("GMT"));
long time = sdf.parse("2016-01-24T16:00:00.000Z").getTime();
long now = System.currentTimeMillis();
CharSequence ago =
DateUtils.getRelativeTimeSpanString(time, now, DateUtils.MINUTE_IN_MILLIS);
b）外部ライブラリ ocpsoft/PrettyTime （Java.util.Dateに基づく）
ここでは、「[2016-01-24T16：00：00.000Z」の解釈としてSimpleDateFormat- resultを生成するために、timeも使用する必要があります。
PrettyTime prettyTime = new PrettyTime(Locale.getDefault());
String ago = prettyTime.format(new Date(time));
c）ライブラリを使用する Time4A （重量がありますが、i18n-supportが最適です）
Moment moment = Iso8601Format.EXTENDED_DATE_TIME_OFFSET.parse("2016-01-24T16:00:00.000Z");
String ago = PrettyTime.of(Locale.getDefault()).printRelativeInStdTimezone(moment);
1-日付フォーマッターを作成します：
public static final SimpleDateFormat inputFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
2-日付オブジェクトの作成
String dateStr = "2016-01-24T16:00:00.000Z";
Date date = inputFormat.parse(dateStr);
3-Android DateUtilsを使用してNice Display文字列を作成します。
String niceDateStr = DateUtils.getRelativeTimeSpanString(date.getTime() , Calendar.getInstance().getTimeInMillis(), DateUtils.MINUTE_IN_MILLIS);
とても簡単です。私のコードで説明します。
package com.example;
import Java.text.SimpleDateFormat;
import Java.util.Date;
import Java.util.concurrent.TimeUnit;
public class TimeShow
{
public static void main(String[] args) {
try
{
SimpleDateFormat format = new SimpleDateFormat("yyyy.MM.dd G 'at' HH:mm:ss");
Date past = format.parse("2016.02.05 AD at 23:59:30");
Date now = new Date();
long seconds=TimeUnit.MILLISECONDS.toSeconds(now.getTime() - past.getTime());
long minutes=TimeUnit.MILLISECONDS.toMinutes(now.getTime() - past.getTime());
long hours=TimeUnit.MILLISECONDS.toHours(now.getTime() - past.getTime());
long days=TimeUnit.MILLISECONDS.toDays(now.getTime() - past.getTime());
//
// System.out.println(TimeUnit.MILLISECONDS.toSeconds(now.getTime() - past.getTime()) + " milliseconds ago");
// System.out.println(TimeUnit.MILLISECONDS.toMinutes(now.getTime() - past.getTime()) + " minutes ago");
// System.out.println(TimeUnit.MILLISECONDS.toHours(now.getTime() - past.getTime()) + " hours ago");
// System.out.println(TimeUnit.MILLISECONDS.toDays(now.getTime() - past.getTime()) + " days ago");
if(seconds<60)
{
System.out.println(seconds+" seconds ago");
}
else if(minutes<60)
{
System.out.println(minutes+" minutes ago");
}
else if(hours<24)
{
System.out.println(hours+" hours ago");
}
else
{
System.out.println(days+" days ago");
}
}
catch (Exception j){
j.printStackTrace();
}
}
}
Android使用できますDateUtils.getRelativeTimeSpanString（long timeInMillis）、 https：//を参照） developer.Android.com/reference/Android/text/format/DateUtils.html その方法のバリエーションの1つを使用して正確にすることができます。
@Excelso_Widiコードを使用して、私は克服することができました、
私は彼のコードを修正し、英語に翻訳しました。
public class TimeAgo2 {
public String covertTimeToText(String dataDate) {
String convTime = null;
String prefix = "";
String suffix = "Ago";
try {
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
Date pasTime = dateFormat.parse(dataDate);
Date nowTime = new Date();
long dateDiff = nowTime.getTime() - pasTime.getTime();
long second = TimeUnit.MILLISECONDS.toSeconds(dateDiff);
long minute = TimeUnit.MILLISECONDS.toMinutes(dateDiff);
long hour = TimeUnit.MILLISECONDS.toHours(dateDiff);
long day = TimeUnit.MILLISECONDS.toDays(dateDiff);
if (second < 60) {
convTime = second+" Seconds "+suffix;
} else if (minute < 60) {
convTime = minute+" Minutes "+suffix;
} else if (hour < 24) {
convTime = hour+" Hours "+suffix;
} else if (day >= 7) {
if (day > 30) {
convTime = (day / 30)+" Months "+suffix;
} else if (day > 360) {
convTime = (day / 360)+" Years "+suffix;
} else {
convTime = (day / 7) + " Week "+suffix;
}
} else if (day < 7) {
convTime = day+" Days "+suffix;
}
} catch (ParseException e) {
e.printStackTrace();
Log.e("ConvTimeE", e.getMessage());
}
return convTime;
}
}
そして、私はこのようにそれを使用しました
String time = jsonObject.getString("date_gmt");
TimeAgo2 timeAgo2 = new TimeAgo2();
String MyFinalValue = timeAgo2.covertTimeToText(time);
ハッピーコーディングと@Excelso_Widiありがとうございますwink
private static final int SECOND_MILLIS = 1000;
private static final int MINUTE_MILLIS = 60 * SECOND_MILLIS;
private static final int HOUR_MILLIS = 60 * MINUTE_MILLIS;
private static final int DAY_MILLIS = 24 * HOUR_MILLIS;
private static Date currentDate() {
Calendar calendar = Calendar.getInstance();
return calendar.getTime();
}
public static String getTimeAgo(Date date) {
long time = date.getTime();
if (time < 1000000000000L) {
time *= 1000;
}
long now = currentDate().getTime();
if (time > now || time <= 0) {
return "in the future";
}
final long diff = now - time;
if (diff < MINUTE_MILLIS) {
return "moments ago";
} else if (diff < 2 * MINUTE_MILLIS) {
return "a minute ago";
} else if (diff < 60 * MINUTE_MILLIS) {
return diff / MINUTE_MILLIS + " minutes ago";
} else if (diff < 2 * HOUR_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";
}
}
getTimeAgo（timeInDate）;を呼び出すだけです。
それは私のために働いています。
手順1.時間型をlong型のミリ秒形式に変換する
ステップ2.以下のコードを使用する
private static final int SECOND_MILLIS = 1000;
private static final int MINUTE_MILLIS = 60 * SECOND_MILLIS;
private static final int HOUR_MILLIS = 60 * MINUTE_MILLIS;
private static final int DAY_MILLIS = 24 * HOUR_MILLIS;
public static String getTimeAgo(long time, Context ctx) {
if (time < 1000000000000L) {
//if timestamp given in seconds, convert to millis time *= 1000; }
long now = getCurrentTime(ctx);
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 + " minutes 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"; } }
// Googleからのコードの上！
Getlongtoagoメソッドでミリ秒を渡すことができ、完全なフォーマットされた文字列を返します
public static String getlongtoago(long createdAt) {
DateFormat userDateFormat = new SimpleDateFormat("E MMM dd HH:mm:ss Z yyyy");
DateFormat dateFormatNeeded = new SimpleDateFormat("MM/dd/yyyy HH:MM:SS");
Date date = null;
date = new Date(createdAt);
String crdate1 = dateFormatNeeded.format(date);
// Date Calculation
DateFormat dateFormat = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss");
crdate1 = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss").format(date);
// get current date time with Calendar()
Calendar cal = Calendar.getInstance();
String currenttime = dateFormat.format(cal.getTime());
Date CreatedAt = null;
Date current = null;
try {
CreatedAt = dateFormat.parse(crdate1);
current = dateFormat.parse(currenttime);
} catch (Java.text.ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// Get msec from each, and subtract.
long diff = current.getTime() - CreatedAt.getTime();
long diffSeconds = diff / 1000;
long diffMinutes = diff / (60 * 1000) % 60;
long diffHours = diff / (60 * 60 * 1000) % 24;
long diffDays = diff / (24 * 60 * 60 * 1000);
String time = null;
if (diffDays > 0) {
if (diffDays == 1) {
time = diffDays + "day ago ";
} else {
time = diffDays + "days ago ";
}
} else {
if (diffHours > 0) {
if (diffHours == 1) {
time = diffHours + "hr ago";
} else {
time = diffHours + "hrs ago";
}
} else {
if (diffMinutes > 0) {
if (diffMinutes == 1) {
time = diffMinutes + "min ago";
} else {
time = diffMinutes + "mins ago";
}
} else {
if (diffSeconds > 0) {
time = diffSeconds + "secs ago";
}
}
}
}
return time;
}
変換しようとしているのはISO 8601準拠フォーマット。これを変換する最も簡単な方法は、Androidで Joda-Timeライブラリ を使用することです。
それをプロジェクトに追加すると、このコードを使用して正確な日付を抽出できます！
DateTimeZone timeZone = DateTimeZone.getDefault();
DateTimeFormatter formatter = DateTimeFormat.forPattern("dd MMMM yyyy").withZone(timeZone);
DateTime dateTime2 = new DateTime( isoDateToBeConverted, timeZone );
String output = formatter.print( dateTime2 );
Log.w("TIME IF WORKS::",""+output);
また、 this を参照して、好みの選択で日付をフォーマットしてください。

私は同じ問題に直面していました（nhandled execption Java.text.ParseExecption）タイムスタンプを時間前の形式に変換しようとしたときに、R＆Dを行った後、最終的に解決策を得ました...今、このエラーは解決されました
- Bulid.gradle（Module：app）にthis（compile 'org.ocpsoft.prettytime：prettytime：4.0.1.Final'）依存関係を追加し、プロジェクトを同期します
この依存関係を追加したら、このメソッドを貼り付けて好きな場所に呼び出します（Log.e（ "TAG"、 "ConvertTimeStampintoAgo：" + ConvertTimeStampintoAgo（1320917972））;）
