毫秒转时间
注意：”HH:mm:ss”是24小时制的，”hh:mm:ss”是12小时制。
看代码：
/** * Created by baiyuanwei on 16/5/3. * * "HH:mm:ss"是24小时制的，"hh:mm:ss"是12小时制。 */public class TimeUtil { /** * 从时间(毫秒)中提取出日期 * * @param millisecond * @return */ public static String getDateFromMillisecond(Long millisecond) { Date date = null; try { date = new Date(millisecond); } catch (Exception e) { e.printStackTrace(); } Calendar current = Calendar.getInstance(); ////今天 Calendar today = Calendar.getInstance(); today.set(Calendar.YEAR, current.get(Calendar.YEAR)); today.set(Calendar.MONTH, current.get(Calendar.MONTH)); today.set(Calendar.DAY_OF_MONTH, current.get(Calendar.DAY_OF_MONTH)); // Calendar.HOUR——12小时制的小时数 Calendar.HOUR_OF_DAY——24小时制的小时数 today.set(Calendar.HOUR_OF_DAY, 0); today.set(Calendar.MINUTE, 0); today.set(Calendar.SECOND, 0); //昨天 Calendar yesterday = Calendar.getInstance(); yesterday.set(Calendar.YEAR, current.get(Calendar.YEAR)); yesterday.set(Calendar.MONTH, current.get(Calendar.MONTH)); yesterday.set(Calendar.DAY_OF_MONTH, current.get(Calendar.DAY_OF_MONTH) - 1); yesterday.set(Calendar.HOUR_OF_DAY, 0); yesterday.set(Calendar.MINUTE, 0); yesterday.set(Calendar.SECOND, 0); // 今年 Calendar thisYear = Calendar.getInstance(); thisYear.set(Calendar.YEAR, current.get(Calendar.YEAR)); thisYear.set(Calendar.MONTH, 0); thisYear.set(Calendar.DAY_OF_MONTH, 0); thisYear.set(Calendar.HOUR_OF_DAY, 0); thisYear.set(Calendar.MINUTE, 0); thisYear.set(Calendar.SECOND, 0); current.setTime(date); //今年以前 if (current.before(thisYear)) { SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd"); String dateStr = format.format(date); return dateStr; } else if (current.after(today)) { return "今天"; } else if (current.before(today) && current.after(yesterday)) { return "昨天"; } else { SimpleDateFormat format = new SimpleDateFormat("MM-dd"); String dateStr = format.format(date); return dateStr; } } /** * 从时间(毫秒)中提取出时间(时:分) * 时间格式: 时:分 * * @param millisecond * @return */ public static String getTimeFromMillisecond(Long millisecond) { SimpleDateFormat simpleDateFormat = new SimpleDateFormat("HH:mm"); Date date = new Date(millisecond); String timeStr = simpleDateFormat.format(date); return timeStr; } /** * 将毫秒转化成固定格式的时间 * 时间格式: yyyy-MM-dd HH:mm:ss * * @param millisecond * @return */ public static String getDateTimeFromMillisecond(Long millisecond){ SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); Date date = new Date(millisecond); String dateStr = simpleDateFormat.format(date); return dateStr; } /** * 将时间转化成毫秒 * 时间格式: yyyy-MM-dd HH:mm:ss * * @param time * @return */ public static Long timeStrToSecond(String time) { try { SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); Long second = format.parse(time).getTime(); return second; } catch (Exception e) { e.printStackTrace(); } return -1l; } /** * 获取时间间隔 * * @param millisecond * @return */ public static String getSpaceTime(Long millisecond) { Calendar calendar = Calendar.getInstance(); Long currentMillisecond = calendar.getTimeInMillis(); //间隔秒 Long spaceSecond = (currentMillisecond - millisecond) / 1000; //一分钟之内 if (spaceSecond >= 0 && spaceSecond < 60) { return "片刻之前"; } //一小时之内 else if (spaceSecond / 60 > 0 && spaceSecond / 60 < 60) { return spaceSecond / 60 + "分钟之前"; } //一天之内 else if (spaceSecond / (60 * 60) > 0 && spaceSecond / (60 * 60) < 24) { return spaceSecond / (60 * 60) + "小时之前"; } //3天之内 else if (spaceSecond/(60*60*24)>0&&spaceSecond/(60*60*24)<3){ return spaceSecond/(60*60*24)+"天之前"; }else { return getDateTimeFromMillisecond(millisecond); } }}更多相关文章
