java - Get date by utc/gmt in Android -


i want display time in country, , timezone gmt+4.

private void loadweather(){     timezone tz = timezone.gettimezone("gmt+0400");     calendar cal = calendar.getinstance(tz);     date date = cal.gettime();     dateformat df = dateformat.getdatetimeinstance(dateformat.short,dateformat.short, locale.getdefault());     string mydate = df.format(date);     tv_time.settext(mydate); }

i've tried this, gives me time, , not other one

the problem you're specifying time zone on calendar - only used current instant in time, doesn't depend on time zone. need specify on format instead, it's applied when creating appropriate text representation of instant:

private void loadweather() {     date date = new date(); // enough; uses current instant.     dateformat df = dateformat.getdatetimeinstance(         dateformat.short, dateformat.short, locale.getdefault());     df.settimezone(timezone.gettimezone("gmt+0400"));     string mydate = df.format(date);     tv_time.settext(mydate); }

or inline more:

private void loadweather() {     dateformat df = dateformat.getdatetimeinstance(         dateformat.short, dateformat.short, locale.getdefault());     df.settimezone(timezone.gettimezone("gmt+0400"));     tv_time.settext(df.format(new date())); }

(this assuming want short date/time format using current locale.)
