Android 从服务器获取时间戳转换为年月日
用JAVA相关类转换。代码如下:
Calendar calendar = Calendar.getInstance(); calendar.setTimeInMillis(NumberUtils.getLong(mss) * 1000); //mss即是从服务器获取的时间戳 SimpleDateFormat sf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); String date = sf.format(calendar.getTime()); //date即是已转换好的时间。
/** * 时间戳转换成日期格式字符串 * @param seconds 精确到秒的字符串 * @param formatStr * @return */ public static String timeStamp2Date(String seconds,String format) { if(seconds == null || seconds.isEmpty() || seconds.equals("null")){ return ""; } if(format == null || format.isEmpty()) format = "yyyy-MM-dd HH:mm:ss"; SimpleDateFormat sdf = new SimpleDateFormat(format); return sdf.format(new Date(Long.valueOf(seconds+"000"))); } /** * 日期格式字符串转换成时间戳 * @param date 字符串日期 * @param format 如:yyyy-MM-dd HH:mm:ss * @return */ public static String date2TimeStamp(String date_str,String format){ try { SimpleDateFormat sdf = new SimpleDateFormat(format); return String.valueOf(sdf.parse(date_str).getTime()/1000); } catch (Exception e) { e.printStackTrace(); } return ""; } /** * 取得当前时间戳(精确到秒) * @return */ public static String timeStamp(){ long time = System.currentTimeMillis(); String t = String.valueOf(time/1000); return t; } // 输出结果: // timeStamp=1417792627 // date=2014-12-05 23:17:07 // 1417792627 public static void main(String[] args) { String timeStamp = timeStamp(); System.out.println("timeStamp="+timeStamp); String date = timeStamp2Date(timeStamp, "yyyy-MM-dd HH:mm:ss"); System.out.println("date="+date); String timeStamp2 = date2TimeStamp(date, "yyyy-MM-dd HH:mm:ss"); System.out.println(timeStamp2); } //将时间戳转换为时分秒 String date = "142925"; SimpleDateFormat dateFormat = new SimpleDateFormat("HH:mm:ss"); Date currentTime = new Date(); String dateString = dateFormat.format(currentTime); System.out.println(dateString);
