可能用到的时间格式转换工具：

  20.                 result_time = result_date.getTime();
  21.                 format.setTimeZone(TimeZone.getDefault());
  22.                 return format.format(result_time);
  23.             } catch (Exception e) {
  24.                 e.printStackTrace();

  26.         }
  27.         return GTMDate;
  29.     }

设置倒计时：

  1. String startTime = StringUtil.GTMToLocal("2015-12-28T12:49:13.45425+08:00");
  2.         String endTime = StringUtil.GTMToLocal("2015-12-31T00:17:13.45425+08:00");
  4.         DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
  6.         try {
  7.             Date d1 = df.parse(startTime);
  8.             Date d2 = df.parse(endTime);
  9.             long diff = d2.getTime() - d1.getTime(); // mslong days = diff / (1000 * 60 * 60 * 24);
  10.             long hours = (diff - days * (1000 * 60 * 60 * 24)) / (1000 * 60 * 60);
  11.             long minutes = (diff - days * (1000 * 60 * 60 * 24) - hours * (1000 * 60 * 60)) / (1000 * 60);
  12.             long second = (diff / 1000 - days * 24 * 60 * 60 - hours * 60 * 60 - minutes * 60);
  14.             hours += days * 24;

                // RushBuyCountDownTimerView     timerView;  需要初始化timerView
  1.  
  1.             timerView.setTime(hours + "", minutes + "", second + "");
  2.             timerView.start();
  4.         } catch (Exception e) {
  5.             e.printStackTrace();
  6.         }
