我使用以下方式覆盖我的应用的区域设置：
Locale locale = new Locale("ca");
Locale.setDefault(locale);
Configuration config = new Configuration();
config.locale = locale;
getBaseContext().getResources().updateConfiguration(config,
getBaseContext().getResources().getDisplayMetrics());
但似乎getRelativeTimeSpanString不适用于应用程序上下文，而是使用系统区域设置。

你的解决方案几乎是正确的。
但是，由于字符串是从系统资源加载的，因此必须更新系统资源的配置。以下是我的所作所为：
Configuration configuration = new Configuration(Resources.getSystem().getConfiguration());
configuration.locale = Locale.GERMANY; // or whichever locale you desire
Resources.getSystem().updateConfiguration(configuration, null);
（注意：从Jelly Bean MR1开始，建议使用
configuration.setLocale(Locale.GERMANY);
更改区域设置，而不是直接设置成员。）
答案 1 :(得分：5)
我今天遇到了这个问题，花了几个小时才解决了＃34;。
我建议你，如果你可以使用getRelativeTimeSpanString（context，long，boolean）来代替。这不是我的情况，因为结果字符串与getRelativeTimeSpanString（long）不同。
我的解决方法需要将一些字符串的一些android内部资源复制到您的代码中，因此如果您需要支持很多语言，那将非常烦人。
我跟踪了Android（4.4 r1）的当前源代码并提取了DateUtils并进行了更改，以便您可以像这样使用它：
CharSequence desiredString = MyDateUtils.getRelativeTimeSpanString(time,
System.currentTimeMillis(),
DateUtils.MINUTE_IN_MILLIS, DateUtils.FORMAT_SHOW_DATE | DateUtils.FORMAT_SHOW_YEAR, activity);
这将给你与getRelativeTimeSpanString（long）相同的结果。
只保留MyDateUtils：
public static CharSequence getRelativeTimeSpanString（long time，long now，long minResolution，int flags，Context c）
我在方法中添加了上下文，然后更改了上下文资源的系统资源以及我自己的字符串的所有内部android字符串（与android＆＃39; s相同，但无法找到使用它们的方法，因为它们是internal）。
private static final String getRelativeDayString（Resources r，long day，long today）
也保持此方法为先前使用的方法。在这里我也改变了字符串。
这是我对MyDateUtils的实现：
import java.util.Locale;
import android.content.Context;
import android.content.res.Resources;
import android.text.format.DateUtils;
import android.text.format.Time;
import com.YOURPACKAGE.R;
/**

* elapsed time and date ranges, strings for days of the week and months, and AM/PM text etc.
*/
public class MyDateUtils
{
/**
* Returns a string describing 'time' as a time relative to 'now'.
* <p>
* Time spans in the past are formatted like "42 minutes ago". Time spans in
* the future are formatted like "in 42 minutes".
* <p>
* Can use {@link #FORMAT_ABBREV_RELATIVE} flag to use abbreviated relative
* times, like "42 mins ago".
*
* @param time the time to describe, in milliseconds
* @param now the current time in milliseconds
* @param minResolution the minimum timespan to report. For example, a time
* 3 seconds in the past will be reported as "0 minutes ago" if
* this is set to MINUTE_IN_MILLIS. Pass one of 0,
* MINUTE_IN_MILLIS, HOUR_IN_MILLIS, DAY_IN_MILLIS,
* WEEK_IN_MILLIS
* @param flags a bit mask of formatting options, such as

public static CharSequence getRelativeTimeSpanString(long time, long now, long minResolution,
int flags, Context c) {

//boolean abbrevRelative = (flags & (FORMAT_ABBREV_RELATIVE | FORMAT_ABBREV_ALL)) != 0;

long duration = Math.abs(now - time);
int resId;

答案 2 :(得分：1)
我使用Custom方法来处理这个问题：
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);
}
我将date设置为此方法的参数：
return getRelativeTimeSpanString(context,this.createdTime);
这个按照我想要的位置返回字符串！希望能帮到你。
