把秒数转换为%d:%02d:%02d 格式

private String stringForTime(int timeSec) {
      int totalSeconds = timeSec;     int seconds = totalSeconds % 60;     int minutes = totalSeconds / 60 % 60;     int hours = totalSeconds / 3600;     if (null!=mFormatBuilder){
          this.mFormatBuilder.setLength(0);     }     return hours > 0 ? this.mFormatter.format("%d:%02d:%02d", new Object[]{Integer.valueOf(hours), Integer.valueOf(minutes), Integer.valueOf(seconds)}).toString() : this.mFormatter.format("%02d:%02d", new Object[]{Integer.valueOf(minutes), Integer.valueOf(seconds)}).toString(); }
