android 获取系统时间的时间戳，时间戳日期互转，计算日期时间差，获取明天日期，比较时间大小

long creatTime=mBindCheck.remainPaymentTime;
int shi = (int)mBindCheck.remainPaymentTime/(3600*1000);
int yu1 = (int)mBindCheck.remainPaymentTime%(3600*1000);
int fen = (int)yu1/(60*1000);
int yu2 = (int)yu1%(60*1000);
int mia = (int)yu2/1000;

获取系统时间戳

public String getTime(){long time=System.currentTimeMillis()/1000;//获取系统时间的10位的时间戳String  str=String.valueOf(time);return str;
}

点击时间差

private long mTouchDownTime;//1000为1秒

mTouchDownTime = SystemClock.uptimeMillis();

if (SystemClock.uptimeMillis() - mTouchDownTime < RANGE_TOUCH_MOVE_INTERVAL) {return;
}

、获取系统时间

SimpleDateFormat df = new SimpleDateFormat("HH");//设置日期格式"yyyy年-MM月dd日-HH时mm分ss秒"String dfd = df.format(new Date());

结果如下

2017年-05月26日-14时49分29秒

时间戳转换日期

public static String timetodate(String time) {Calendar calendar = Calendar.getInstance();calendar.setTimeInMillis(Long.valueOf(time));SimpleDateFormat sf = new SimpleDateFormat("MM-dd ");//这里的格式可换"yyyy年-MM月dd日-HH时mm分ss秒"等等格式String date = sf.format(calendar.getTime());return date;}

时间日期转换成时间戳

/** 将时间转换为时间戳*/
public static String dateToStamp(String s) throws ParseException {String res;SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");Date date = simpleDateFormat.parse(s);long ts = date.getTime();res = String.valueOf(ts);return res;
}

/*** 四舍五入到小数点后scale位* @param v* @param scale* @return*/
public static float round(float v, int scale)
{if (scale < 0)throw new IllegalArgumentException("The scale must be a positive integer or zero");BigDecimal bgNum1 = new BigDecimal(Float.toString(v));BigDecimal bgNum2 = new BigDecimal("1");return bgNum1.divide(bgNum2, scale, BigDecimal.ROUND_HALF_UP).floatValue();// return b.setScale(scale, BigDecimal.ROUND_HALF_UP).floatValue();
}

转换日期时间格式

public static String getDistanceTimeToHM(String str1) {DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");String typestring = "yyyy-MM-dd HH:mm";String endtime="";Date one;try {one = df.parse(str1);endtime = dateToString(one,typestring);} catch (ParseException e) {e.printStackTrace();}return endtime;
}

public static String dateToString(Date data, String formatType) {return new SimpleDateFormat(formatType).format(data);
}

如2017-11-01 09:16:03.0转换后是2017-11-01 09:16

计算两个日期时间差，天数，时、分、秒、

public  int getDistanceTime(String end, String start) {DateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");Date one;Date two;long day = 0;long hour = 0;long min = 0;long sec = 0;try {final Calendar c = Calendar.getInstance();c.setTimeZone(TimeZone.getTimeZone("GMT+8:00"));one = df.parse(end);c.setTime(one);two = df.parse(start);long time1 = one.getTime();long time2 = two.getTime();long diff ;diff = time1 - time2;day = diff / (24 * 60 * 60 * 1000);//天数Log.i("lgq","tian--==="+day+"...one="+end+"..-----.two==="+start);hour = (diff / (60 * 60 * 1000) - day * 24);//时min = ((diff / (60 * 1000)) - day * 24 * 60 - hour * 60);//分sec = ((diff/1000)- day * 24 * 60 * 60 - hour * 60 * 60 - min * 60);} catch (ParseException e) {e.printStackTrace();}return (int)sec;
}

获取明天日期

//获得明天日期
   private String getTomoData(){

   // 添加大小月月份并将其转换为list,方便之后的判断
       String[] months_big = { "1", "3", "5", "7", "8", "10", "12" };
       String[] months_little = { "4", "6", "9", "11" };

       List<String> list_big = Arrays.asList(months_big);
       List<String> list_little = Arrays.asList(months_little);

       Calendar calendar = Calendar.getInstance();
       int year = calendar.get(Calendar.YEAR);
       int month = calendar.get(Calendar.MONTH)+1;
       int day = calendar.get(Calendar.DATE);
       if(day==30){
           if (list_big.contains(String.valueOf(month))){
               day=31;
           }
           if (list_little.contains(String.valueOf(month))){
               day=1;
               if(month==12){
                   year++;
                   month=1;
               }else{
                   month++;
               }

           }
       }else if(day==31){
           day=1;
           if(month==12){
               year++;
               month=1;
           }else{
               month++;
           }

       }else {
           day++;
       }
   String data;
   if( day<10)
   {

       data=year+"-"+"0"+month+"-"+"0"+day;
   }
   else
   {
       data=year+"-"+"0"+month+"-"+day;
       }

       return data;
   }

比较时间大小/

/*** 对比两个时间** @param startTimedama* @param endTime* @return*/
public static boolean getTimeCompareSize(String startTimedama, String endTime) {int i = 0;SimpleDateFormat dateFormat = new SimpleDateFormat("MM月dd日 HH:mm:ss");//年-月-日 时-分try {Date date1 = dateFormat.parse(startTime);//开始时间Date date2 = dateFormat.parse(endTime);//结束时间// 1 结束时间小于开始时间 2 开始时间与结束时间相同 3 结束时间大于开始时间if (date2.getTime() < date1.getTime()) {i = 1;} else if (date2.getTime() == date1.getTime()) {i = 2;} else if (date2.getTime() > date1.getTime()) {//正常情况下的逻辑操作.i = 3;}} catch (ParseException e) {e.printStackTrace();}if (i == 1 || i == 2) {return true;} else {return false;}
}
