Я ищу способ установить максимальный и минимальный тайм-аут на Android TimePickerDialog и изменить минутный интервал по умолчанию от 1 мин до 5 мин,
Я думал, что это было легко, но я не могу найти способ!
Android TimePickerDialog устанавливает максимальное время
Ответ 1
Это расширение для ответов fiddlers. Как-то onTimeChangedListener не установлен TimePickerDialog в некоторых версиях Android:
Метод onTimeChanged никогда не называется! Лучшим решением для этой проблемы в настоящее время является возможность кодирования пользовательского TimePickerDialog с минимальной/макс логикой от скрипача.
Более уродливая работа - это. (Добавление слушателя с использованием отражений) Я также обновляю заголовок, чтобы показать выбранное время.

Вы можете использовать это как отправную точку.
Я расширил TimePickerDialog и добавил 2 метода setMin и setMax.
В методе onTimeChanged я проверяю, что новое время действует в отношении минимальных/максимальных времен.
Он по-прежнему нуждается в полировке, хотя...
public class BoundTimePickerDialog extends TimePickerDialog {
private int minHour = -1, minMinute = -1, maxHour = 100, maxMinute = 100;
private int currentHour, currentMinute;
public BoundTimePickerDialog(Context context, OnTimeSetListener callBack, int hourOfDay, int minute, boolean is24HourView) {
super(context, callBack, hourOfDay, minute, is24HourView);
}
public void setMin(int hour, int minute) {
minHour = hour;
minMinute = minute;
}
public void setMax(int hour, int minute) {
maxHour = hour;
maxMinute = minute;
}
@Override
public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
super.onTimeChanged(view, hourOfDay, minute);
boolean validTime;
if(hourOfDay < minHour) {
validTime = false;
}
else if(hourOfDay == minHour) {
validTime = minute >= minMinute;
}
else if(hourOfDay == maxHour) {
validTime = minute <= maxMinute;
}
else {
validTime = true;
}
if(validTime) {
currentHour = hourOfDay;
currentMinute = minute;
}
else {
updateTime(currentHour, currentMinute);
}
}
}

Для lolipop и более высокой версии Android вы можете использовать этот модифицированный класс RangeTimePickerDialog
(Из lolipop Timepicker использует режим часов (дизайн материала) по умолчанию, чтобы старый пользовательский класс не работал. Мы можем изменить режим на spinner для последней версии и повторно использовать класс)
public class RangeTimePickerDialog extends TimePickerDialog {

Не существует встроенных методов для установки максимального/минимального времени, но, возможно, он работает, если вы расширяете onTimeChanged или updateTime, вы можете запретить устанавливать время вне значения за пределами ваших границ.

После рефакторированного кода скрипача:

public RangeTimePickerDialog(Context context, OnTimeSetListener callBack, int hourOfDay,
int minute, boolean is24HourView) {
super(context, callBack, hourOfDay, minute, is24HourView);
mCurrentHour = hourOfDay;
mCurrentMinute = minute;
// Somehow the onTimeChangedListener is not set by TimePickerDialog
// in some Android Versions, so, Adding the listener using
// reflections
try {
Class<?> superclass = getClass().getSuperclass();
Field mTimePickerField = superclass.getDeclaredField("mTimePicker");
mTimePickerField.setAccessible(true);
TimePicker mTimePicker = (TimePicker) mTimePickerField.get(this);
mTimePicker.setOnTimeChangedListener(this);

Надеюсь, это поможет. Я использовал библиотеку времени Joda.
public class RangeTimePicker extends TimePicker implements
TimePicker.OnTimeChangedListener {
private int mMinHour = -1;
private int mMinMinute = -1;
private int mMaxHour = 25;
private int mMaxMinute = 61;
private int mCurrentHour;
private int mCurrentMinute;
public RangeTimePicker(Context context) {
super(context);
setOnTimeChangedListener(this);
}
public RangeTimePicker(Context context, AttributeSet attrs) {
super(context, attrs);
setOnTimeChangedListener(this);
}
public RangeTimePicker(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
setOnTimeChangedListener(this);
}
public void setMaxTime(int hourIn24, int minute) {
mMaxHour = hourIn24;
mMaxMinute = minute;
LocalTime currentTime = LocalTime.now();
LocalTime maxTime = new LocalTime(mMaxHour, mMaxMinute);
if (currentTime.isAfter(maxTime)) {
this.setCurrentHour(mCurrentHour = currentTime.getHourOfDay());
this.setCurrentMinute(
mCurrentMinute = currentTime.getMinuteOfHour());
}
}
public void setMinTime(int hourIn24, int minute) {
mMinHour = hourIn24;
mMinMinute = minute;
LocalTime currentTime = LocalTime.now();
LocalTime minTime = new LocalTime(mMinHour, mMinMinute);
if (currentTime.isBefore(minTime)) {
this.setCurrentHour(mCurrentHour = minTime.getHourOfDay());
this.setCurrentMinute(mCurrentMinute = minTime.getMinuteOfHour());
}
}
@Override
public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
boolean validTime = true;
if (hourOfDay < mMinHour || (hourOfDay == mMinHour
&& minute < mMinMinute)) {
validTime = false;
}
if (hourOfDay > mMaxHour || (hourOfDay == mMaxHour
&& minute > mMaxMinute)) {
validTime = false;
}
if (validTime) {
mCurrentHour = hourOfDay;
mCurrentMinute = minute;
}
setCurrentHour(mCurrentHour);
setCurrentMinute(mCurrentMinute);
}
}

Надеюсь на эту работу, она отлично работает со мной...
Установите максимальное время для выбора времени.
timePicker.setOnTimeChangedListener(new TimePicker.OnTimeChangedListener() {
@Override
public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
if (!mIsOnTimeChanged) {
mIsOnTimeChanged = true;
Calendar c = Calendar.getInstance();
//get the selected day if it is before today allow AM and PM trick
//else apply rules
int selected_year = datePicker.getYear();
int selected_month = datePicker.getMonth();
int selected_day = datePicker.getDayOfMonth();
int today = c.get(Calendar.DAY_OF_MONTH);
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH);
int hour = c.get(Calendar.HOUR);
hour += 12;
int min = c.get(Calendar.MINUTE);
//Check if user enter hh | mm | more than current reset the timePicker with the current time
//http://stackoverflow.com/questions/2659954/timepickerdialog-and-am-or-pm
if ((hourOfDay == hour | hour < hourOfDay | hourOfDay > hour | hour > hourOfDay | minute > min) && (selected_month == month && selected_day == today && selected_year == year)) {
int AM_PM_Value = hourOfDay;
Calendar datetime = Calendar.getInstance();
int hour_without_24 = (hour - 12);
if ((datetime.get(Calendar.AM_PM) == Calendar.AM) && (hourOfDay > hour_without_24)) {
//set AM
timePicker.setCurrentHour(hour - 12);
}
if (hourOfDay == (hour - 12) && minute > min) {
timePicker.setCurrentMinute(min);
}
if (hourOfDay > hour && datetime.get(Calendar.AM_PM) != Calendar.AM) {
timePicker.setCurrentHour(hour);
if (minute > min) {
timePicker.setCurrentMinute(min);
}
}
} else if (selected_month != month | selected_day != today | selected_year != year) {
} else if (hourOfDay == hour && minute > min) {
timePicker.setCurrentMinute(min);
} else if (hourOfDay > hour) {
timePicker.setCurrentHour(hour);
if (minute > min) {
timePicker.setCurrentMinute(min);
}
}
//
isTimePickerChanged = true;
String AM_PM;
if (hourOfDay < 12) {
AM_PM = "AM";
} else {
AM_PM = "PM";
}
//to set as 12 hour
time_format = (hourOfDay + ":" + minute + ":" + "00");
if (hourOfDay > 12) {
hourOfDay = (hourOfDay - 12);
}
st_time = (hourOfDay + ":" + pad(minute) + " " + AM_PM);
mIsOnTimeChanged = false;
}
}

Вы можете просто использовать пользовательский TimePicker с отражением для установки значений.
@Override
protected void onAttachedToWindow() {
super.onAttachedToWindow();
try {
Class<?> classForid = Class.forName("com.android.internal.R$id");
Field field = classForid.getField("minute");
NumberPicker mMinuteSpinner = (NumberPicker) findViewById(field.getInt(null));
mMinuteSpinner.setMinValue(5);
mMinuteSpinner.setMaxValue((60 / timeInterval) - 1);
List<String> displayedValues = new ArrayList<>();
for (int i = 0; i < 60; i += timeInterval)
displayedValues.add(String.format("%02d", i));
mMinuteSpinner.setDisplayedValues(displayedValues.toArray(new String[0]));
mMinuteSpinner.setWrapSelectorWheel(true);
} catch (Exception e) {
e.printStackTrace();
}
}
Итак, вы можете установить, какие значения вы хотите

В качестве отправной точки я принял решение @Zarooka. Я думаю, что нашел ошибку. Если у вас было начальное время, которое уже было вне диапазона, то вы больше не могли его перемещать, потому что любой "onChanged" отклонялся. Вот почему я расширил setMax и setMin, чтобы перейти в допустимый диапазон при настройке mins/maxs.
