Zeitdifferenz mit String wie „Vor einer Minute“ oder „Vor einer Stunde“ auf Android

Question

bekommen habe ich diesen Code in meinem PHP

function nicetime($date) 
{ 
date_default_timezone_set("Asia/Taipei"); 
if(empty($date)) { 
    return "No date provided"; 
} 

$periods   = array("second", "minute", "hour", "day", "week", "month", "year", "decade"); 
$lengths   = array("60","60","24","7","4.35","12","10"); 

$now    = time(); 
$unix_date   = strtotime($date); 

    // check validity of date 
if(empty($unix_date)) {  
    return "Bad date"; 
} 

// is it future date or past date 
if($now > $unix_date) {  
    $difference  = $now - $unix_date; 
    $tense   = "ago"; 

} else { 
    $difference  = $unix_date - $now; 
    $tense   = "from now"; 
} 

for($j = 0; $difference >= $lengths[$j] && $j < count($lengths)-1; $j++) { 
    $difference /= $lengths[$j]; 
} 

$difference = round($difference); 

if($difference != 1) { 
    $periods[$j].= "s"; 
} 

return "$difference $periods[$j] {$tense}"; 
} 

aber jetzt mag ich das gleiche tun, aber dieses Mal in meinem Android . Ich habe Probleme, weil die Zeichenfolge mytime aus einer Datenbank in einem SQL-Format ist.

String mytime = pref.getString("announcementtime" + count, null); 

Ausgabe von mytime:

2013-08-31 15:55:22 

ich möchte es konvertieren:

23 minutes ago //something like this 

Bitte beachten Sie die Standard-Zeitzone und die Datetime = Jetzt

Answer 1

Es ist alles in der DateUtils Klasse.

CharSequence getRelativeTimeSpanString (long time, long now, long minResolution); 

gibt Ihnen den Unterschied zwischen der Zeit und jetzt in einem Format wie:

54 Sekunden.

Um die Datumszeichenfolge Sie es in empoch Zeit zuerst konvertieren zu verwenden:

String mytime = pref.getString("announcementtime" + count, null); 

// it comes out like this 2013-08-31 15:55:22 so adjust the date format 
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); 
Date date = df.parse(str); 
long epoch = date.getTime(); 

String timePassedString = getRelativeTimeSpanString (epoch, System.currentTimeMillis(), DateUtils.SECOND_IN_MILLIS); 

Answer 2

Es gibt eine schöne Bibliothek für genau diesen Zweck über auf Github: https://github.com/curioustechizen/android-ago

Answer 3

Sie können die Eingangsvariablen „timeAtMiliseconds“ ändern, für mein Beispiel im Format von Datum bei miliseconds war war.

public static String parseDate(String timeAtMiliseconds) { 
    if (timeAtMiliseconds.equalsIgnoreCase("")) { 
     return ""; 
    } 
    //API.log("Day Ago "+dayago); 
    String result = "now"; 
    SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); 
    String todayDate = formatter.format(new Date()); 
    Calendar calendar = Calendar.getInstance(); 

    long dayagolong = Long.valueOf(timeAtMiliseconds) * 1000; 
    calendar.setTimeInMillis(dayagolong); 
    String agoformater = formatter.format(calendar.getTime()); 

    Date CurrentDate = null; 
    Date CreateDate = null; 

    try { 
     CurrentDate = formatter.parse(todayDate); 
     CreateDate = formatter.parse(agoformater); 

     long different = Math.abs(CurrentDate.getTime() - CreateDate.getTime()); 

     long secondsInMilli = 1000; 
     long minutesInMilli = secondsInMilli * 60; 
     long hoursInMilli = minutesInMilli * 60; 
     long daysInMilli = hoursInMilli * 24; 

     long elapsedDays = different/daysInMilli; 
     different = different % daysInMilli; 

     long elapsedHours = different/hoursInMilli; 
     different = different % hoursInMilli; 

     long elapsedMinutes = different/minutesInMilli; 
     different = different % minutesInMilli; 

     long elapsedSeconds = different/secondsInMilli; 

     different = different % secondsInMilli; 
     if (elapsedDays == 0) { 
      if (elapsedHours == 0) { 
       if (elapsedMinutes == 0) { 
        if (elapsedSeconds < 0) { 
         return "0" + " s"; 
        } else { 
         if (elapsedDays > 0 && elapsedSeconds < 59) { 
          return "now"; 
         } 
        } 
       } else { 
        return String.valueOf(elapsedMinutes) + "m ago"; 
       } 
      } else { 
       return String.valueOf(elapsedHours) + "h ago"; 
      } 

     } else { 
      if (elapsedDays <= 29) { 
       return String.valueOf(elapsedDays) + "d ago"; 
      } 
      if (elapsedDays > 29 && elapsedDays <= 58) { 
       return "1Mth ago"; 
      } 
      if (elapsedDays > 58 && elapsedDays <= 87) { 
       return "2Mth ago"; 
      } 
      if (elapsedDays > 87 && elapsedDays <= 116) { 
       return "3Mth ago"; 
      } 
      if (elapsedDays > 116 && elapsedDays <= 145) { 
       return "4Mth ago"; 
      } 
      if (elapsedDays > 145 && elapsedDays <= 174) { 
       return "5Mth ago"; 
      } 
      if (elapsedDays > 174 && elapsedDays <= 203) { 
       return "6Mth ago"; 
      } 
      if (elapsedDays > 203 && elapsedDays <= 232) { 
       return "7Mth ago"; 
      } 
      if (elapsedDays > 232 && elapsedDays <= 261) { 
       return "8Mth ago"; 
      } 
      if (elapsedDays > 261 && elapsedDays <= 290) { 
       return "9Mth ago"; 
      } 
      if (elapsedDays > 290 && elapsedDays <= 319) { 
       return "10Mth ago"; 
      } 
      if (elapsedDays > 319 && elapsedDays <= 348) { 
       return "11Mth ago"; 
      } 
      if (elapsedDays > 348 && elapsedDays <= 360) { 
       return "12Mth ago"; 
      } 

      if (elapsedDays > 360 && elapsedDays <= 720) { 
       return "1 year ago"; 
      } 

      if (elapsedDays > 720) { 
       SimpleDateFormat formatterYear = new SimpleDateFormat("MM/dd/yyyy"); 
       Calendar calendarYear = Calendar.getInstance(); 
       calendarYear.setTimeInMillis(dayagolong); 
       return formatterYear.format(calendarYear.getTime()) + ""; 
      } 

     } 

    } catch (java.text.ParseException e) { 
     e.printStackTrace(); 
    } 
    return result; 
}
