我的PHP中有此代码
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}";
}
但是现在我想做同样的事情,但是这次是在我的Android中。即时通讯遇到了麻烦,因为字符串mytime来自SQL格式的数据库。
String mytime = pref.getString("announcementtime" + count, null);
mytime的输出:
2013-08-31 15:55:22
我想将其转换为:
23 minutes ago //something like this
请注意默认时区和DateTime = Now
它全部在DateUtils类中。
CharSequence getRelativeTimeSpanString (long time, long now, long minResolution);
通过以下格式为您提供时间与现在之间的时差:
54秒前。
要使用日期字符串,您必须先将其转换为时间点时间:
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);
