I override the locale of my app using:
Locale locale = new Locale("ca");
Locale.setDefault(locale);
Configuration config = new Configuration();
config.locale = locale;
getBaseContext().getResources().updateConfiguration(config,
getBaseContext().getResources().getDisplayMetrics());
But it seems that getRelativeTimeSpanString doesn't work with application context, and instead use the system locale.
On
I had this problem today and took me several hours to "solve".
I recommend you that if you can use getRelativeTimeSpanString(context, long, boolean) instead do so. It was not my case as the resulting string is not the same as getRelativeTimeSpanString(long).
My workaround requires to copy some android internal resources of a couple of strings to your code so it will be quite annoying if you have a lot of languages to support.
I tracked the current source code of Android (4.4 r1) and extracted DateUtils and changed so you can use it like this:
CharSequence desiredString = MyDateUtils.getRelativeTimeSpanString(time,
System.currentTimeMillis(),
DateUtils.MINUTE_IN_MILLIS, DateUtils.FORMAT_SHOW_DATE | DateUtils.FORMAT_SHOW_YEAR, activity);
That will give you the same result as getRelativeTimeSpanString(long).
To make MyDateUtils i only kept:
public static CharSequence getRelativeTimeSpanString(long time, long now, long minResolution, int flags, Context c)
I added the context to the method, then changed the system resources for context resources and all the internal android strings for my own strings (which are the same as android's but couldnt find a way to use them as they were internal).
private static final String getRelativeDayString(Resources r, long day, long today)
Also kept this method as its used by the prior. Here i changed the strings as well.
This is my implementation of MyDateUtils:

import android.content.Context;
import android.content.res.Resources;
import android.text.format.DateUtils;
import android.text.format.Time;

I use Custom method to handle this:
public static String getRelativeTimeSpanString(Context context, Date fromdate) {
long then;
then = fromdate.getTime();
Date date = new Date(then);
StringBuffer dateStr = new StringBuffer();
Calendar calendar = Calendar.getInstance();
calendar.setTime(date);
Calendar now = Calendar.getInstance();
int days = daysBetween(calendar.getTime(), now.getTime());
int weeks= days/7;
int minutes = hoursBetween(calendar.getTime(), now.getTime());
int hours = minutes / 60;
if (days == 0) {
int second = minuteBetween(calendar.getTime(), now.getTime());
if (minutes > 60) {
if (hours >= 1 && hours <= 24) {
dateStr.append(String.format("%s %s %s",
hours,
context.getString(R.string.hour)
,context.getString(R.string.ago)));
}
}else {
if (second <= 10) {
dateStr.append(context.getString(R.string.now));
} else if (second > 10 && second <= 30) {
dateStr.append(context.getString(R.string.few_seconds_ago));
} else if (second > 30 && second <= 60) {
dateStr.append(String.format("%s %s %s",
second,
context.getString(R.string.seconds)
,context.getString(R.string.ago)));
} else if (second >= 60 && minutes <= 60) {
dateStr.append(String.format("%s %s %s",
minutes,
context.getString(R.string.minutes)
,context.getString(R.string.ago)));
}
}
} else
if (hours > 24 && days < 7) {
dateStr.append(String.format("%s %s %s",
days,
context.getString(R.string.days)
,context.getString(R.string.ago)));
}else if(weeks == 1){
dateStr.append(String.format("%s %s %s",
weeks,
context.getString(R.string.weeks)
,context.getString(R.string.ago)));
}
else {
/**
* make formatted createTime by languageTag("fa")
*
* @return
*/
return SimpleDateFormat.getDateInstance(SimpleDateFormat.LONG,new Locale("fra"))
.format(date).toUpperCase();
}
return dateStr.toString();
}
public static int minuteBetween(Date d1, Date d2) {
return (int) ((d2.getTime() - d1.getTime()) / android.text.format.DateUtils.SECOND_IN_MILLIS);
}
public static int hoursBetween(Date d1, Date d2) {
return (int) ((d2.getTime() - d1.getTime()) / android.text.format.DateUtils.MINUTE_IN_MILLIS);
}
public static int daysBetween(Date d1, Date d2) {
return (int) ((d2.getTime() - d1.getTime()) / android.text.format.DateUtils.DAY_IN_MILLIS);
}
and I set date as a parameter to this method:
return getRelativeTimeSpanString(context,this.createdTime);
this return string by location as I wanted! hope to help.
Your solution was almost correct.
However, since the strings are loaded from the system resources, you must update the configuration of the system resources. Below is what I did:
(NB: From Jelly Bean MR1 onwards, it is recommended to use
to change the locale rather then setting the member directly.)
