我有一个类似2019-02-28T11：30：00.000Z的日期，我想将其转换成以前的格式，或者在我使用它之前的格式，但是它显示以前的格式不正确，请解决此问题。
public class CustomDateFormat {
public static String DateToTimeFormat(String oldstringDate) {
PrettyTime p = new PrettyTime();
String isTime = null;
try {
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss",new Locale(getCountry()));
sdf.setTimeZone(TimeZone.getTimeZone("UTC"));
Date date = sdf.parse(oldstringDate);
isTime = p.format(date);
} catch (ParseException e) {
e.printStackTrace();
}
return isTime;
}
public static String DateFormat(String oldstringDate) {
String newDate;
SimpleDateFormat dateFormat = new SimpleDateFormat("E, d MMM yyyy",
new Locale(getCountry()));
try {
Date date = new SimpleDateFormat("yyyy-MM-dd", new Locale(getCountry())).parse(oldstringDate);
newDate = dateFormat.format(date);
} catch (ParseException e) {
e.printStackTrace();
newDate = oldstringDate;
}
return newDate;
}
public static String getCountry() {
Locale locale = Locale.getDefault();
String country = String.valueOf(locale.getCountry());
return country.toLowerCase();
}
}

我有一些东西可以找出“ ago”。同样，您可以尝试使用“之前”
public String gettimeago(String ntime) {
final int SECOND_MILLIS = 1000;
final int MINUTE_MILLIS = 60 * SECOND_MILLIS;
final int HOUR_MILLIS = 60 * MINUTE_MILLIS;
final int DAY_MILLIS = 24 * HOUR_MILLIS;
if (ntime != null) {
long earlier = Long.parseLong(ntime);
long now = System.currentTimeMillis();
if (earlier < 1000000000000L) {
earlier *= 1000;
}
if (earlier > now || earlier <= 0) {
return null;
}
final long diff = now - earlier;
if (diff < MINUTE_MILLIS) {
return "just now";
} else if (diff < 2 * MINUTE_MILLIS) {
return "a minute ago";
} else if (diff < 50 * MINUTE_MILLIS) {
return (diff / MINUTE_MILLIS + " minutes ago");
} else if (diff < 90 * MINUTE_MILLIS) {
return "a hour ago";
} else if (diff < 24 * HOUR_MILLIS) {
return (diff / HOUR_MILLIS + " hours ago");
} else if (diff < 48 * HOUR_MILLIS) {
return "yesterday";
} else {
return diff / DAY_MILLIS + " days ago";
}
}
return "";
}
