Android 时间戳转换 SimpleDateFormat

Stringres;

SimpleDateFormat simpleDateFormat =new SimpleDateFormat(pattern);

long lt =new Long(milSecond);

Date date =new Date(lt);

res = simpleDateFormat.format(date);

return res;

很奇怪  转换出来是1970年

Stringres;

SimpleDateFormat simpleDateFormat =new SimpleDateFormat(pattern);

long lt =new Long(milSecond);

Date date =new Date(lt *1000L);

res = simpleDateFormat.format(date);

return res;

就加了个*1000L

可以了
