How to convert time to " time ago " in android
Solution 1:
I see mainly three ways:
a) built-in options using SimpleDateFormat
and DateUtils
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
sdf.setTimeZone(TimeZone.getTimeZone("GMT"));
try {
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);
} catch (ParseException e) {
e.printStackTrace();
}
b) external library ocpsoft/PrettyTime (based on java.util.Date
)
Here you have to use SimpleDateFormat
, too, to produce the time
-result as interpretation of "2016-01-24T16:00:00.000Z".
import below lib in your app
implementation 'org.ocpsoft.prettytime:prettytime:4.0.1.Final'
PrettyTime prettyTime = new PrettyTime(Locale.getDefault());
String ago = prettyTime.format(new Date(time));
c) using my library Time4A (heavyweight but with best i18n-support)
Moment moment = Iso8601Format.EXTENDED_DATE_TIME_OFFSET.parse("2016-01-24T16:00:00.000Z");
String ago = PrettyTime.of(Locale.getDefault()).printRelativeInStdTimezone(moment);
Solution 2:
1 - create date formatter:
public static final SimpleDateFormat inputFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
2 - create Date object
String dateStr = "2016-01-24T16:00:00.000Z";
Date date = inputFormat.parse(dateStr);
3 - Use Android DateUtils to create a nice Display string:
String niceDateStr = DateUtils.getRelativeTimeSpanString(date.getTime() , Calendar.getInstance().getTimeInMillis(), DateUtils.MINUTE_IN_MILLIS);
