Java 测试当前时间两个值之间是否匹配？

我想测试当前时间。 这两次是一样的吗

-带着便条，我已经完成了一项工作 函数输入开始时间 是时候结束了

现在我想完成这个特殊的功能。 我正在测试这两次之间的输入值

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState){
      super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        int hourStart = 5;
        int minuteStart = 30;
        String PMAMStart="AM";
        int hourEnd = 6;
        int minuteEnd = 30;
        String PMAMEnd="AM";

       boolean checkTime=  checkCurrentTimeBetweenTowVlue(hourStart,minuteStart,PMAMStart,hourEnd,minuteEnd,PMAMEnd);

    }


    private boolean checkCurrentTimeBetweenTowVlue(int hStart,int mStart,String ampmStart,int hEnd,int mEnd,String ampmEnd){

      Calendar cal = Calendar.getInstance();

      return false;
    }


}

从cal对象获取当前分钟和小时数。将开始、结束和当前时间转换为分钟，这样比较起来就很容易了

private boolean checkCurrentTimeBetweenTowVlue(int hStart,int mStart,String ampmStart,int hEnd,int mEnd,String ampmEnd){

  Calendar cal = Calendar.getInstance();
  int hours = cal.get(Calendar.HOUR_OF_DAY);
  int minutes = cal.get(Calendar.MINUTE); 

  if(ampmStart.equals("PM")){
     hStart += 12;
  }
  int minutes_start = hStart*60 + mStart; 

  if(ampmEnd.equals("PM")){
     hEnd += 12;
  }
  int minutes_end = hEnd*60 + mEnd; 

  int minutes_curr = hours*60 + minutes;


  if(minutes_curr>minutes_start && minutes_curr<minutes_end){
     return true;
  }

  return false;
}

private boolean checkCurrentTimeBetweenTowVlue（int-hStart，int-mStart，String-ampmStart，int-hEnd，int-mEnd，String-ampmEnd）{
Calendar cal=Calendar.getInstance（）；
int hours=cal.get（日历小时）；
int minutes=cal.get（Calendar.minutes）；
if（ampmStart.equals（“PM”））{
hStart+=12；
}
int minutes_start=hStart*60+mStart；
如果（安培数等于（“PM”））{
hEnd+=12；
}
分钟内结束=hEnd*60+修复；
int minutes\u curr=小时*60+分钟；
在您的情况下，如果（分钟数>分钟数>开始时间和分钟数，您可以为开始日期和结束日期设置单独的日历字段，如上午、下午、小时和分钟，将时间转换为分钟，然后找出时间之间的差异。解决方案如下：

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState){
      super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        int hourStart = 5;
        int minuteStart = 30;
        String PMAMStart="AM";
        int hourEnd = 6;
        int minuteEnd = 30;
        String PMAMEnd="AM";

        boolean checkTime=  checkCurrentTimeBetweenTwoValues(hourStart,minuteStart,PMAMStart,hourEnd,minuteEnd,PMAMEnd);

        if (checkTime) {
            System.out.println("Time is Same");
        } else {
            System.out.println("Time is not Same");
        }

    }

    private boolean checkCurrentTimeBetweenTwoValues(int hStart,int mStart,String ampmStart,int hEnd,int mEnd,String ampmEnd){

      Calendar startCalendar = Calendar.getInstance();
      Calendar endCalendar = Calendar.getInstance();

      if (ampmStart.equalsIgnoreCase("AM")) {
          startCalendar.set(Calendar.AM_PM, 0);
      } else {
          startCalendar.set(Calendar.AM_PM, 1);
      }

      startCalendar.setTimeZone(TimeZone.getDefault());
      startCalendar.set(Calendar.HOUR, hStart);
      startCalendar.set(Calendar.MINUTE, mStart);

      if (ampmEnd.equalsIgnoreCase("AM")) {
          endCalendar.set(Calendar.AM_PM, 0);
      } else {
          endCalendar.set(Calendar.AM_PM, 1);
      }

      endCalendar.setTimeZone(TimeZone.getDefault());
      endCalendar.set(Calendar.HOUR, hEnd);
      endCalendar.set(Calendar.MINUTE, mEnd);

      long timeDifference = TimeUnit.MILLISECONDS.toMinutes(
            Math.abs(endCalendar.getTimeInMillis() - startCalendar.getTimeInMillis()));
      System.out.println(("Time Difference: " + timeDifference));

      return (timeDifference == 0);
    }
}

public static boolean isNowBetween(int startHour, int startMinute, int endHour, int endMinute) {
    LocalTime start = LocalTime.of(startHour, startMinute);
    LocalTime end = LocalTime.of(endHour, endMinute);
    LocalTime now = LocalTime.now();
    return now.isAfter(start) && now.isBefore(end);
}

您还可以使用
TimeUnit.millizes.toSeconds
检查秒数，但为此，您需要设置日历实例的
Seconds
组件

如果您可以使用Java 8（从Android中的API级别26开始），或者如果您愿意/能够/允许导入，那么以下可能是一个不错的解决方案：

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState){
      super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        int hourStart = 5;
        int minuteStart = 30;
        String PMAMStart="AM";
        int hourEnd = 6;
        int minuteEnd = 30;
        String PMAMEnd="AM";

        boolean checkTime=  checkCurrentTimeBetweenTwoValues(hourStart,minuteStart,PMAMStart,hourEnd,minuteEnd,PMAMEnd);

        if (checkTime) {
            System.out.println("Time is Same");
        } else {
            System.out.println("Time is not Same");
        }

    }

    private boolean checkCurrentTimeBetweenTwoValues(int hStart,int mStart,String ampmStart,int hEnd,int mEnd,String ampmEnd){

      Calendar startCalendar = Calendar.getInstance();
      Calendar endCalendar = Calendar.getInstance();

      if (ampmStart.equalsIgnoreCase("AM")) {
          startCalendar.set(Calendar.AM_PM, 0);
      } else {
          startCalendar.set(Calendar.AM_PM, 1);
      }

      startCalendar.setTimeZone(TimeZone.getDefault());
      startCalendar.set(Calendar.HOUR, hStart);
      startCalendar.set(Calendar.MINUTE, mStart);

      if (ampmEnd.equalsIgnoreCase("AM")) {
          endCalendar.set(Calendar.AM_PM, 0);
      } else {
          endCalendar.set(Calendar.AM_PM, 1);
      }

      endCalendar.setTimeZone(TimeZone.getDefault());
      endCalendar.set(Calendar.HOUR, hEnd);
      endCalendar.set(Calendar.MINUTE, mEnd);

      long timeDifference = TimeUnit.MILLISECONDS.toMinutes(
            Math.abs(endCalendar.getTimeInMillis() - startCalendar.getTimeInMillis()));
      System.out.println(("Time Difference: " + timeDifference));

      return (timeDifference == 0);
    }
}

public static boolean isNowBetween(int startHour, int startMinute, int endHour, int endMinute) {
    LocalTime start = LocalTime.of(startHour, startMinute);
    LocalTime end = LocalTime.of(endHour, endMinute);
    LocalTime now = LocalTime.now();
    return now.isAfter(start) && now.isBefore(end);
}

您尝试过什么，会出现什么错误。除非是要求，否则最好使用
DateTime
的子类之一，例如
LocalDateTime
，从内存中有两种方法可以使用。您的应用程序支持的最低API级别是什么？如果是26或更高，则使用
java.time
for这个.不工作我输入：int hourStart=4；int minuteStart=05；String PMAMStart=“PM”；int hourEnd=4；int minuteEnd=30；String PMAMEnd=“PM”，现在的时间等于下午4:03打印：时间不一样
