TimePicker-如何设置上午或下午?

标签: android android-timepicker

我是android新手,在我的应用中,我这里有一个时间选择器,我需要以编程方式设置小时,分钟,AM / PM值。

时间值是“ 11:11:AM”,在此我设置了小时和时间,并且工作正常。但是我不知道如何设置AM / PM值。

代码:

  if (!(mTime == null)) {
                String timme = mTime;
                String[] time = timme.split(":");
                int hour = Integer.parseInt(time[0].trim());
                int min = Integer.parseInt(time[1].trim());
                String amPm = ((time[2].trim()));

                mTimePicker.setIs24HourView(false);
                mTimePicker.setHour(hour);
                mTimePicker.setMinute(min);
            }

即使字符串具有“ PM”,它也始终显示“ AM”。 谁能帮我解决这个问题。

像这样打电话,

mTimePicker.setIs24HourView(false);

Android会根据24小时格式提供的时间自动设置AM / PM。要澄清:

您必须通过调用

将TimePicker设置为12小时模式
#!/usr/bin/python3
# ./dataparse.py
from __future__ import print_function
from signal import signal, SIGPIPE, SIG_DFL
signal(SIGPIPE,SIG_DFL)
import re
with open('test2', 'r') as f:
    for line in f:
        line = line.strip()
        data = f.read()
        regex = (r"dn:(.*?)\nftpuser: (.*)\ndescription:* (.*)")
        matchObj = re.findall(regex, data)
        for index in matchObj:
            #print(index)
            index_str = ' '.join(index)
            new_str = re.sub(r'[=,]', ' ', index_str)
            new_str = new_str.split()
            print("{0:<30}{1:<20}{2:<50}".format(new_str[1],new_str[8],new_str[9]))

,然后使用24小时制提供时间

$ ./dataparse.py
ab02                          disabled_5Mar07     Remedy
mela                          Y                   ROYALS|none|customer
ab01                          Y                   VGVzdGluZyA
tt@regg.com                   T                   REG-JP|7-31-05|REG-JP

如果我是你,我将把字符串拆开,检查最后一部分是AM还是PM,如果是PM,我会在小时值上加上12,因此如果是yourtimepicker.setIs24HourView(false) ,我会得到23小时,它到android,并让它处理其他所有事情。

注意:这适用于微调器和时钟模式

String = aTime24 hour格式的字符串

   mTimePicker = new TimePickerDialog(context, new TimePickerDialog.OnTimeSetListener() {
                @Override
                public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {
                    String timeSet;
                    if (selectedHour > 12) {
                        selectedHour -= 12;
                        timeSet = "PM";
                    } else if (selectedHour == 0) {
                        selectedHour += 12;
                        timeSet = "AM";
                    } else if (selectedHour == 12)
                        timeSet = "PM";
                    else
                        timeSet = "AM";
                    String minutes = "";
                    if (selectedMinute < 10)
                        minutes = "0" + selectedMinute;
                    else
                        minutes = String.valueOf(selectedMinute);

                    String aTime = new StringBuilder().append(selectedHour).append(':')
                            .append(minutes).append(" ").append(timeSet).toString();

                    relatedWorkTime.setText(aTime);

                }
            }, hour, minute, false);
            mTimePicker.setTitle("Select Time");
            mTimePicker.show();

使用以下代码将24小时制转换为12小时制,并添加AM / PM。

String time =  ((hourOfDay > 12) ? hourOfDay % 12 : hourOfDay) + ":" + (minute < 10 ? ("0" + minute) : minute) + " " + ((hourOfDay >= 12) ? "PM" : "AM");

请在下面找到android timepicker的完整代码。


final Calendar c = Calendar.getInstance();
                mHour = c.get(Calendar.HOUR_OF_DAY);
                mMinute = c.get(Calendar.MINUTE);

                // Launch Time Picker Dialog
                TimePickerDialog timePickerDialog = new TimePickerDialog(CreateNewBatchActivity.this,
                        new TimePickerDialog.OnTimeSetListener() {

                            @Override
                            public void onTimeSet(TimePicker view, int hourOfDay,
                                                  int minute) {
                                String time =  ((hourOfDay > 12) ? hourOfDay % 12 : hourOfDay) + ":" + (minute < 10 ? ("0" + minute) : minute) + " " + ((hourOfDay >= 12) ? "PM" : "AM");

                                buttonBatchStartTime.setText(time);
                            }
                        }, mHour, mMinute, false);
                timePickerDialog.show();
