目前显示的时间为13:35 PM 但是,我想显示为AM/PM的12小时格式,即下午1:35而不是下午13:35

当前代码如下所示

private static final int FOR_HOURS = 3600000;
private static final int FOR_MIN = 60000;
public String getTime(final Model model) {
    SimpleDateFormat formatDate = new SimpleDateFormat("HH:mm a");
    formatDate.setTimeZone(userContext.getUser().getTimeZone());
    model.addAttribute("userCurrentTime", formatDate.format(new Date()));
    final String offsetHours = String.format("%+03d:%02d", userContext.getUser().getTimeZone().getRawOffset()
    / FOR_HOURS, Math.abs(userContext.getUser().getTimeZone().getRawOffset() % FOR_HOURS / FOR_MIN));
    model.addAttribute("offsetHours",
                offsetHours + " " + userContext.getUser().getTimeZone().getDisplayName(Locale.ROOT));
    return "systemclock";
}

当前回答

// hh:mm will print hours in 12hrs clock and mins (e.g. 02:30)
System.out.println(DateTimeFormatter.ofPattern("hh:mm").format(LocalTime.now()));

// HH:mm will print hours in 24hrs clock and mins (e.g. 14:30)
System.out.println(DateTimeFormatter.ofPattern("HH:mm").format(LocalTime.now())); 

// hh:mm a will print hours in 12hrs clock, mins and AM/PM (e.g. 02:30 PM)
System.out.println(DateTimeFormatter.ofPattern("hh:mm a").format(LocalTime.now())); 

其他回答

SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd hh:mm a");

这将显示日期和时间

    //To get Filename + date and time


    SimpleDateFormat f = new SimpleDateFormat("MMM");
    SimpleDateFormat f1 = new SimpleDateFormat("dd");
    SimpleDateFormat f2 = new SimpleDateFormat("a");

    int h;
         if(Calendar.getInstance().get(Calendar.HOUR)==0)
            h=12;
         else
            h=Calendar.getInstance().get(Calendar.HOUR)

    String filename="TestReport"+f1.format(new Date())+f.format(new Date())+h+f2.format(new Date())+".txt";


The Output Like:TestReport27Apr3PM.txt

如果你想要当前时间与AM, PM在Android使用

String time = new SimpleDateFormat("hh : mm a", Locale.getDefault()).format(Calendar.getInstance().getTime());

如果你想要当前时间的上午,下午

String time = new SimpleDateFormat("hh : mm a", Locale.getDefault()).format(Calendar.getInstance().getTime()).toLowerCase();

OR

API级别26

LocalTime localTime = LocalTime.now();
DateTimeFormatter dateTimeFormatter = DateTimeFormatter.ofPattern("hh:mm a");
String time = localTime.format(dateTimeFormatter);

只需替换下面的语句,它将工作。

SimpleDateFormat formatDate = new SimpleDateFormat("hh:mm a");
SimpleDateFormat sdf = new SimpleDateFormat("hh:mm:ss a");

("hh:mm:ss a") >>>这里如果我们不使用'a',那么24hours将会出现。所以如果我们想在你的时间AM/PM播放,只需添加这个格式。如有任何疑问,请告诉我。
