我有一个将 is24Hour 设置为 false 的 TimePickerDialog，因为我想向最终用户展示更熟悉的 12 小时格式。当设置小时、分钟和 AM PM 指示器并返回时间时，如何识别最终用户选择的是 AM 还是 PM？

这就是我为听众准备的：

private TimePickerDialog.OnTimeSetListener mTimeSetListener =
      new TimePickerDialog.OnTimeSetListener() {

    @Override
    public void onTimeSet(TimePicker view, int hourOfDay, 
      int minute) {
     mHour = hourOfDay;
     mMinute = minute;
    // mIsAM = WHERE CAN I GET THIS VALUE
    }
};

将hourOfDay始终是 24 小时。如果您打开对话框并is24HourView设置为false，用户将不必处理 24 小时格式的时间，但 Android 会在调用 时将其转换为 24 小时时间onTimeSet()。

This worked for me:

public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
    String am_pm = "";

    Calendar datetime = Calendar.getInstance();
    datetime.set(Calendar.HOUR_OF_DAY, hourOfDay);
    datetime.set(Calendar.MINUTE, minute);

    if (datetime.get(Calendar.AM_PM) == Calendar.AM)
        am_pm = "AM";
    else if (datetime.get(Calendar.AM_PM) == Calendar.PM)
        am_pm = "PM";

    String strHrsToShow = (datetime.get(Calendar.HOUR) == 0) ?"12":datetime.get(Calendar.HOUR)+""; 

    ((Button)getActivity().findViewById(R.id.btnEventStartTime)).setText( strHrsToShow+":"+datetime.get(Calendar.MINUTE)+" "+am_pm );
}

我遇到了同样的问题。我的应用程序中有一个 TimePicker，在您选择时间并点击按钮后，您将被带到显示所选时间的屏幕。选择的“时间”是正确的，但有时 AM/PM 值会与选择的相反。我最终通过更改我为 TimePicker 中的“hrs”参数存储的内容来修复它。

private TimePickerDialog.OnTimeSetListener mTimeSetListener = new TimePickerDialog.OnTimeSetListener() 
{   
    @Override
    public void onTimeSet(TimePicker view, int hrs, int mins)
    {
        hour = hrs;
        minute = mins;

        c = Calendar.getInstance();
        c.set(Calendar.HOUR_OF_DAY, hour);
        //instead of c.set(Calendar.HOUR, hour);
        c.set(Calendar.MINUTE, minute);

现在，当我按下按钮进入下一个屏幕时，它会正确显示选择的正确 AM/PM 值。

试试这个简单的方法：

 void openTimeFragment() {
        TimePickerDialog mTimePicker;

        final Calendar c = Calendar.getInstance();
        int hour = c.get(Calendar.HOUR_OF_DAY);
        int minute = c.get(Calendar.MINUTE);

        mTimePicker = new TimePickerDialog(YourActivity.this, new TimePickerDialog.OnTimeSetListener() {
            @Override
            public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {



                String time = selectedHour + ":" + selectedMinute;

                  SimpleDateFormat fmt = new SimpleDateFormat("HH:mm");
        Date date = null;
        try {
            date = fmt.parse(time );
        } catch (ParseException e) {

            e.printStackTrace();
        }

        SimpleDateFormat fmtOut = new SimpleDateFormat("hh:mm aa");

          String formattedTime=fmtOut.format(date);

                edtTextTime.setText(formattedTime);
            }
        }, hour, minute, false);//No 24 hour time
        mTimePicker.setTitle("Select Time");
        mTimePicker.show();
    }

            }
            else {

您好，您可以像这样使用自己的格式： 

    String myFormat = "hh:mm a"; // your own format
    SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);
    String  formated_time = sdf.format(calendar_time.getTime()); //format your time

我发现“a”是表示 AM-PM 的格式化时间代码：http ://www.tutorialspoint.com/java/java_date_time.htm

如果您的期望是直接在时间选择器对话框中设置 AM/PM，则可以解决此问题。如果您使用当前/默认时间预先填充 EditText，则此方法有效。- 在实例化对话框之前，如果 EditText 具有 PM 时间值，则将小时分量增加 12。

sref_Time3 是安培值；sref_Time1 是小时分量。

    if (sref_Time3.equals("PM")) {
        hour = hour + 12;
    } else if (sref_Time1.equals("12")) {
        hour = 0;
    }
    // Create a new instance of TimePickerDialog and return it
    return new TimePickerDialog(getActivity(), this, hour, minute,
               DateFormat.is24HourFormat(getActivity()));

感谢和问候。

            **//In Below Code Time Format Should be in small letters ie, hh:mm

无论您将 is24Hour 设置为 false 还是 true，您始终会根据“onTimeSet()”方法中的 24 小时格式收到“hourOfDay”。例如：- 如果您将“is24Hour”设置为 false 并选择 8 pm，那么“onTimeSet()”方法中“hourOfDay”的值将是 20。然后您可以像这样设置您的 Am 和 Pm：

 public void onTimeSet(TimePicker timePicker, int hourOfDay, int minute) {

            String minute_precede = "", hour_precede = "", finalTIme = "", amOrPm = "";
            int hourValue = 0;

            Calendar datetime = Calendar.getInstance();
            datetime.set(Calendar.HOUR_OF_DAY, hourOfDay);
            datetime.set(Calendar.MINUTE, minute);

            if (datetime.get(Calendar.AM_PM) == Calendar.AM) {
                amOrPm = "AM";
                if (hourOfDay == 0)
                    hourValue = 12;
                else
                    hourValue = hourOfDay;
            } else if (datetime.get(Calendar.AM_PM) == Calendar.PM) {
                amOrPm = "PM";
                if (hourOfDay == 12)
                    hourValue = 12;
                else if (hourOfDay >= 13 && hourOfDay <= 23)
                    hourValue = hourOfDay - 12;
            }
            if (hourValue < 10)
                hour_precede = "0";
            if (minute < 10)
                minute_precede = "0";
            finalTIme = hour_precede + hourValue + ":" + minute_precede + minute + " " + amOrPm;

                    if(strMin.length()==1) strMin="0" + strMin;

            }, hour, minute, false);//Yes 24 hour time

在使用 TimeDialog 获取时间并将其设置为 EditText 时，我发现如果“分钟”小于 0，例如：12:05，它会给出 12:5。在这段代码中，我已经解决了这个问题，并且如果您想要 12 小时格式，还可以正确使用 TimeDialog 来获取 AM/PM。将您的 onTimeSet() 替换为以下内容

                    int hour = 0;

    val context: Context,
    private val inputTime: String,
    val callback: (time: String) -> Unit
) {
    fun showPicker() {
        var hour = 0
        var minute = 0
        val formattedInputTime = covertDate(
            inputTime,
            Constants.DateFormats.HH_MM_A,
            Constants.DateFormats.HH_MM
        )
        if (formattedInputTime.isNotEmpty()) {
            val arr = formattedInputTime.split(":")
            hour = arr[0].toInt()
            minute = arr[1].toInt()
        }
        val timePickerDialog = TimePickerDialog(
            context,
            { view, h, m ->
                callback(
                    covertDate(
                        "$h:$m",
                        Constants.DateFormats.HH_MM,
                        Constants.DateFormats.HH_MM_A
                    )
                )
            },
            hour,
            minute,
            false
        )
        timePickerDialog.show()
    }

}



@SuppressLint("SimpleDateFormat")
fun covertDate(date: String, inputFormat: String, outputFormat: String): String {
    var formattedDate = ""
    try {
        val dateObject =
            SimpleDateFormat(inputFormat).parse(date)
        formattedDate = SimpleDateFormat(outputFormat).format(dateObject)
    } catch (e: Exception) {
        Timber.e(e)
    }

    return formattedDate
}

//Belongs to Constants class
    object DateFormats {
            const val TIME_STAMP_WITH_ZONE: String = "yyyy-MM-dd'T'HH:mm:ss.s"
            const val MMM_YYYY: String = "MMM YYYY"
            const val DD_MM_YY: String = "dd/MM/yy"
            const val HH_MM_A: String = "hh:mm aa"
            const val HH_MM: String = "HH:mm"
        }

我知道答案为时已晚，并且已经选择了完美的答案，但是我认为对于初学者来说还不是很清楚，所以发布我的答案

editText.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            // TODO Auto-generated method stub
            Calendar mcurrentTime = Calendar.getInstance();
            int hour = mcurrentTime.get(Calendar.HOUR_OF_DAY);
            int minute = mcurrentTime.get(Calendar.MINUTE);

            TimePickerDialog mTimePicker;
            mTimePicker = new TimePickerDialog(getActivity(), new TimePickerDialog.OnTimeSetListener() {
                @Override
                public void onTimeSet(TimePicker timePicker, int selectedHour, int selectedMinute) {
                    String AM_PM;
                    if (selectedHour >=0 && selectedHour < 12){
                        AM_PM = "AM";
                    } else {
                        AM_PM = "PM";
                    }
                    editText.setText( selectedHour + ":" + selectedMinute+" "+AM_PM);
                }
            }, hour, minute, false);
            mTimePicker.setTitle("Select Time");
            mTimePicker.show();
        }
    });

这种方法使用现有的格式功能，上午/下午和 24 小时格式之间的决定取决于是否在timePickerDialog24 小时支持下打开。科特林的例子。

val timePickerDialog = TimePickerDialog(
    requireContext(), TimePickerDialog.OnTimeSetListener { timePicker, hourOfDay, minutes ->

        val datetime = Calendar.getInstance()
        datetime.set(Calendar.HOUR_OF_DAY, hourOfDay)
        datetime.set(Calendar.MINUTE, minutes)

        val timeFormatAmPm = SimpleDateFormat("hh:mm aa")
        val timeFormat24Hours = SimpleDateFormat("HH:mm")

        timeEditTextView.setText(
            when (timePicker.is24HourView) {
                true -> timeFormat24Hours.format(datetime.time)
                false -> timeFormatAmPm.format(datetime.time)
            }
        )
    },
    currentHour, currentMinute, is24HourFormat
)

这是TimePicker已从系统默认值 (24h) 转换为 (12h with AM 和 PM) 的工作示例，我已将其影响到我的FormField：

onTap: () {

    showTimePicker(builder: (context, childWidget) {
            return MediaQuery(
                data: MediaQuery.of(context).copyWith(
                    // Using 24-Hour format
                    alwaysUse24HourFormat: false),
                // If you want 12-Hour format, just change alwaysUse24HourFormat to false or remove all the builder argument
                child: childWidget!);
        },
        context: context,
        initialTime: TimeOfDay.now()
    ).then((value) {
        if (value != null) {
            if (value.period == DayPeriod.am) {
                timeController.text = value.format(context) + " AM";
            } else {
                timeController.text = value.format(context) + " PM";
            }

        }

    }).catchError((error) {
        print('the Error is : ${error.toString()}');
    });
},
