getting time difference with string like "A minute ago" or "An hour ago" on Android -

i have code in 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($unix_date)) {         return "bad date"; }  // future date or past date if($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}"; } 

but want same time in android. im having trouble because string mytime database, in sql format.

string mytime = pref.getstring("announcementtime" + count, null); 

output of mytime:

2013-08-31 15:55:22 

i want convert to:

23 minutes ago //something 

please aware of default timezone , datetime = now

its in dateutils class.

charsequence getrelativetimespanstring (long time, long now, long minresolution); 

gives difference between time , in format like:

54 seconds ago.

to use date string have convert empoch time first:

string mytime = pref.getstring("announcementtime" + count, null);   // comes out 2013-08-31 15:55:22 adjust 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);
