How to set custom Time in TimePicker

How to set custom Time in TimePicker - java

TimePicker shows current time as default in TimePicker, but what if i want to set default time in time picker as per my requirement.
Like its 11:10 when i am writing this, but in TimePicker i like to show 01:00 as default (my mean 2 hours difference, and minutes should be 00 only)
static final int TIME_DIALOG_ID = 1;
public int year,month,day,hour,minute;
private int mYear, mMonth, mDay,mHour,mMinute;
public TimePickerActivity() {
// Assign current Date and Time Values to Variables
final Calendar c = Calendar.getInstance();
mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);
mHour = c.get(Calendar.HOUR_OF_DAY);
mMinute = c.get(Calendar.MINUTE);
}
private TimePickerDialog.OnTimeSetListener mTimeSetListener =
new TimePickerDialog.OnTimeSetListener() {
public void onTimeSet(TimePicker view, int hourOfDay, int min) {
hour = hourOfDay;
minute = min;
String formattedMinutes = "" + min;
String formattedHour = "" + hourOfDay;
if (hourOfDay < 10) {
formattedHour = "0" + hourOfDay;
}
if (min < 10) {
formattedMinutes = "0" + min;
}
textTime.setText(formattedHour + ":" + formattedMinutes);
}
};
#Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case TIME_DIALOG_ID:
TimePickerDialog timePickerDialog = new TimePickerDialog(this, mTimeSetListener, mHour, mMinute, false);
return timePickerDialog;
}
return null;
}

You can do this with following code:
private TimePicker timePicker;
timePicker = (TimePicker) dialog.findViewById(R.id.timePickerDialog);
if(DateFormat.is24HourFormat(getActivity()){
timePicker.setIs24HourView(true);
}else {
timePicker.setIs24HourView(false);
}
// here you can define your hour and minute value.
timePicker.setCurrentHour(hour);
timePicker.setCurrentMinute(minute);

You can try below code
SimpleDateFormat sdf = new SimpleDateFormat("hh:ss");
Date date = null;
try {
date = sdf.parse("07:00");
} catch (ParseException e) {
}
Calendar c = Calendar.getInstance();
c.setTime(date);
TimePicker picker = new TimePicker(getApplicationContext());
picker.setCurrentHour(c.get(Calendar.HOUR_OF_DAY));
picker.setCurrentMinute(c.get(Calendar.MINUTE));

How can I set the specific selected date to min date in android date picker? (java)

I have 2 DatePickers, one is start date picker and the other is end date picker. I want to set the min date of the end DatePicker to the start date which user has selected.
I set the Data which user selected in Calander startDate and set this data as MinDate at end date.
I've tried in this way but it's not working :(
I can't use Mateiral Range Date Picker because I have to use specific theme.
Also I'm not good at programming so I'd appreciate it if you could explain it in detail.
ipDcEventStartDay.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v){
final Calendar c = Calendar.getInstance();
startYear = c.get(Calendar.YEAR);
startMonth = c.get(Calendar.MONTH);
startDay = c.get(Calendar.DAY_OF_MONTH);
DatePickerDialog dpd = new DatePickerDialog(DoubleCheckEventActivity.this, new DatePickerDialog.OnDateSetListener() {
#Override
public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
startYear = year;
startMonth = month+1;
startDay = dayOfMonth;
ipDcEventStartDay.setText(startYear + " - " + startMonth + " - " + startDay);
ipDcEventStartDay.setTextColor(Color.parseColor("#000000"));
}
}, startYear, startMonth, startDay);
dpd.show();
}
});
Calendar startDate = Calendar.getInstance();
startDate.set(Calendar.YEAR, startYear);
startDate.set(Calendar.MONTH, startMonth);
startDate.set(Calendar.DAY_OF_MONTH, startDay);
ipDcEventEndDay.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final Calendar c = Calendar.getInstance();
endYear = c.get(Calendar.YEAR);
endMonth = c.get(Calendar.MONTH);
endDay = c.get(Calendar.DAY_OF_MONTH);
DatePickerDialog dpd = new DatePickerDialog(DoubleCheckEventActivity.this, new DatePickerDialog.OnDateSetListener() {
#Override
public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
endYear = year;
endMonth = month;
endDay = dayOfMonth;
ipDcEventEndDay.setText(endYear + " - " + (endMonth+1) + " - " + endDay);
ipDcEventEndDay.setTextColor(Color.parseColor("#000000"));
}
}, endYear,endMonth, endDay);
dpd.getDatePicker().setMinDate(startDate.getTimeInMillis());
dpd.show();
}
});

This code:
startDate.set(Calendar.YEAR, startYear);
startDate.set(Calendar.MONTH, startMonth);
startDate.set(Calendar.DAY_OF_MONTH, startDay);
Should be inside
ipDcEventEndDay.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
Because startYear, startMonth and startDay are only set on ipDcEventStartDay.setOnClickListener(), so at the beginning they have some value but not the one that was set on ipDcEventStartDay.setOnClickListener()
So in ipDcEventEndDay.setOnClickListener() you have to set again on startDate the values that were picked on the other DatePickerDialog

TimePickerDialog Constructor Issues

if (v == btnEndTimePicker) {
final Calendar c = Calendar.getInstance() ;
mHour = c.get(Calendar.HOUR_OF_DAY);
mMinutes = c.get(Calendar.MINUTE);
TimePickerDialog timePickerDialog = new TimePickerDialog(true, this,
(view, hour, minutes) -> {
return editStartTime.setText((hour + ":" + minutes), mHour, mMinutes);
});
timePickerDialog.show();
}
if (v == btnStartTimePicker) {
final Calendar c = Calendar.getInstance() ;
sHour = c.get(Calendar.HOUR_OF_DAY);
sMinutes = c.get(Calendar.MINUTE);
CalendarDialog timePickerDialog = new CalendarDialog(true, this,
(view, hour, minutes) -> {
return editStartTime.setText((hour + ":" + minutes), sHour, sMinutes);
});
timePickerDialog.show();
}
I'm not sure what to do here, I used a similar code to pop up a Calendar Date Dialog and choose a date that is then dropped into an EditText field. When I do it for TimePickerDialog it says it it's expecting a char[] not a String.

You Give Wrong Parameters to TimePickerDialog object its get
public TimePickerDialog (Context context,
TimePickerDialog.OnTimeSetListener listener,
int hourOfDay,
int minute,
boolean is24HourView)
replace this
TimePickerDialog timePickerDialog = new TimePickerDialog(true, this,
(view, hour, minutes) -> {
return editStartTime.setText((hour + ":" + minutes), mHour, mMinutes);
});
with
TimePickerDialog timePickerDialog = new TimePickerDialog(this,listener,2,25,true);
these are right Parameters for more check it out

Get difference in seconds between selected and right now date and time in Android Java?

How to get duration between selected time (using graphical date and time picker) and date and time now in seconds?
Both methods getSelectedDate() and getSelectedTime() look fine, selected date and time is fine. But there is something wrong with the method getCountDuration(). The value is incorrect. And I can't find an error.

Android Date Time picker in one dialog

I am using material Date Time picker for my Android app. But I want to combine the Date and Time picker in one dialog.
I am following this one. But I need to select the time right after the date selection.
Please suggest possible way to do this one.

You can call TimePicker after DatePicker set Date. Like this..
String date_time = "";
int mYear;
int mMonth;
int mDay;
int mHour;
int mMinute;
et_show_date_time = (EditText) findViewById(R.id.et_show_date_time);
btn_set_date_time = (Button) findViewById(R.id.btn_set_date_time);
btn_set_date_time.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
datePicker();
}
});
Date Picker:
private void datePicker(){
// Get Current Date
final Calendar c = Calendar.getInstance();
mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);
DatePickerDialog datePickerDialog = new DatePickerDialog(this,
new DatePickerDialog.OnDateSetListener() {
#Override
public void onDateSet(DatePicker view, int year,int monthOfYear, int dayOfMonth) {
date_time = dayOfMonth + "-" + (monthOfYear + 1) + "-" + year;
//*************Call Time Picker Here ********************
tiemPicker();
}
}, mYear, mMonth, mDay);
datePickerDialog.show();
}
Time Picker
private void tiemPicker(){
// Get Current Time
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(this,
new TimePickerDialog.OnTimeSetListener() {
#Override
public void onTimeSet(TimePicker view, int hourOfDay,int minute) {
mHour = hourOfDay;
mMinute = minute;
et_show_date_time.setText(date_time+" "+hourOfDay + ":" + minute);
}
}, mHour, mMinute, false);
timePickerDialog.show();
}

Kotlin
Here's the tested Kotlin code for combining the DatePickerDialog and TimePickerDialog together. It becomes simpler because of the support of the closures in Kotlin. The following function should be placed in your Fragment or Activity. The requireContext() method is a member of Fragment. If you are using Activity, use applicationContext instead.
private fun pickDateTime() {
val currentDateTime = Calendar.getInstance()
val startYear = currentDateTime.get(Calendar.YEAR)
val startMonth = currentDateTime.get(Calendar.MONTH)
val startDay = currentDateTime.get(Calendar.DAY_OF_MONTH)
val startHour = currentDateTime.get(Calendar.HOUR_OF_DAY)
val startMinute = currentDateTime.get(Calendar.MINUTE)
DatePickerDialog(requireContext(), DatePickerDialog.OnDateSetListener { _, year, month, day ->
TimePickerDialog(requireContext(), TimePickerDialog.OnTimeSetListener { _, hour, minute ->
val pickedDateTime = Calendar.getInstance()
pickedDateTime.set(year, month, day, hour, minute)
doSomethingWith(pickedDateTime)
}, startHour, startMinute, false).show()
}, startYear, startMonth, startDay).show()
}
Call the above function in onClickListener of your button as following:
button.setOnClickListener { pickDateTime() }
That's it!
If you want to show clock in 12 hour or 24 hour format depending on user's settings, replace false with DateFormat.is24HourFormat(requireContext())

Dialogs calls via method showDialog(...), possible to release object when it not need anymore (in onDestroy() in activity f.e).

Calling code
new CustomDateTimePicker(context,
new CustomDateTimePicker.ICustomDateTimeListener() {
#Override
public void onSet(Dialog dialog, Calendar calendarSelected,
Date dateSelected, int year,
String monthFullName,
String monthShortName,
int monthNumber, int date,
String weekDayFullName,
String weekDayShortName, int hour24,
int hour12,
int min, int sec, String AM_PM) {

#Override

.showDialog();

If you need to select the time right after the date selection you can simply show TimePickerDialog automatically after date is selected. This is the easiest way.
While you have listener that is fired when date is selected with selected date, you can simply pass that selected date to TimePickerDialog and with a few customization in mdtp_time_picker_dialog.xml you can add a TextView to show the selected text.
Another option is merging mdtp_time_picker_dialog.xml and mdtp_date_picker_dialog.xml that are root layouts for date picker dialog and time picker dialog. You can set time picker part visibility as GONE and switch the visibility when you want to switch pickers.
The second solution is more difficult to implement because in addition to layouts, you have to merge all controls and listeners.
If you want the user to see both of the pickers, I think you actually need to design a new view yourself. That library layouts is not suitable for this.

Use this simple code.. I'm using this code in my Project..
final Calendar currentDate = Calendar.getInstance();
date = Calendar.getInstance();
DatePickerDialog datePickerDialog = new DatePickerDialog(getContext(), new DatePickerDialog.OnDateSetListener() {
#Override
public void onDateSet(DatePicker datePicker, int year, int monthOfYear, int dayOfMonth) {
date.set(year, monthOfYear, dayOfMonth);
new TimePickerDialog(getContext(), new TimePickerDialog.OnTimeSetListener() {
#Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
date.set(Calendar.HOUR_OF_DAY, hourOfDay);
date.set(Calendar.MINUTE, minute);
// Log.v(TAG, "The choosen one " + date.getTime());
// Toast.makeText(getContext(),"The choosen one " + date.getTime(),Toast.LENGTH_SHORT).show();
datetime.setText(new SimpleDateFormat("dd-MMM-yyyy h:mm a").format(date.getTime()));
}
},currentDate.get(Calendar.HOUR_OF_DAY), currentDate.get(Calendar.MINUTE), false).show();
}
}, currentDate.get(Calendar.YEAR), currentDate.get(Calendar.MONTH), currentDate.get(Calendar.DATE));
datePickerDialog.getDatePicker().setMinDate(currentDate.getTimeInMillis());
datePickerDialog.show();

You Can Get Date And Time One By One Using Pickers In Android.
Calendar getDate = Calendar.getInstance();
cDay = getDate.get(Calendar.DAY_OF_MONTH);
cMonth = getDate.get(Calendar.MONTH);
cYear = getDate.get(Calendar.YEAR);
timePickerDialog = new TimePickerDialog(DesignActivity.this, new TimePickerDialog.OnTimeSetListener() {
#Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
final String AM_PM ;
if (hourOfDay > 12) {
hourOfDay -= 12;
AM_PM = "pm";
} else if (hourOfDay == 0) {
hourOfDay += 12;
AM_PM = "am";
} else if (hourOfDay == 12)
AM_PM = "pm";
else
AM_PM = "am";
hour1 = hourOfDay;
minutes1 = minute;
DatePickerDialog datePicker = new DatePickerDialog(DesignActivity.this, new DatePickerDialog.OnDateSetListener() {
#Override
public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
cYear = year;
cMonth = month;
cDay = dayOfMonth;
editText.setText(hour1 + ":" +minutes1 + AM_PM + " " + cDay + "/" + cMonth + "/" + cYear);
}
},cYear,cMonth,cDay);
datePicker.show();
}
},hour1,minutes1,false);
timePickerDialog.show();
}
});

Based on #Yogesh Umesh Vaity's answer, I made an object for showing a DateTimePicker in Kotlin.
class DateTimePicker(val context: Context, var pickTime:Boolean = false, var calendar: Calendar = Calendar.getInstance(),
var callback: (it : DateTimePicker) -> Unit) {
companion object{
#JvmStatic
fun getFormat(format : String) : String{
when(format){
"d" -> return "dd/MM/yyyy"
"t" -> return "HH:mm"
"dt" -> return "dd/MM/yyyy HH:mm"
}
return "dd/MM/yyyy"
}
}
fun show(){
val startYear = calendar.get(Calendar.YEAR)
val startMonth = calendar.get(Calendar.MONTH)
val startDay = calendar.get(Calendar.DAY_OF_MONTH)
val startHour = calendar.get(Calendar.HOUR_OF_DAY)
val startMinute = calendar.get(Calendar.MINUTE)
DatePickerDialog(context, DatePickerDialog.OnDateSetListener { _, year, month, day ->
if(pickTime) {
TimePickerDialog(context, TimePickerDialog.OnTimeSetListener { _, hour, minute ->
calendar.set(year, month, day, hour, minute)
callback(this)
}, startHour, startMinute, true).show()
} else {
calendar.set(year,month,day)
callback(this)
}
}, startYear, startMonth, startDay).show()
}
fun showTime(){
val startYear = calendar.get(Calendar.YEAR)
val startMonth = calendar.get(Calendar.MONTH)
val startDay = calendar.get(Calendar.DAY_OF_MONTH)
val startHour = calendar.get(Calendar.HOUR_OF_DAY)
val startMinute = calendar.get(Calendar.MINUTE)
TimePickerDialog(context, TimePickerDialog.OnTimeSetListener { _, hour, minute ->
calendar.set(startYear, startMonth, startDay, hour, minute)
callback(this)
}, startHour, startMinute, true).show()
}
}
You could use the object from your Activity like this:
// Open Date Picker only and set an EditText
DateTimePicker(this){
val sdf = SimpleDateFormat(DateTimePicker.getFormat("d"), Locale.getDefault())
editText.setText(sdf.format(it.calendar.time))
}.show()
// Open Date Picker then Time picker and set an EditText
DateTimePicker(this, true){
val sdf = SimpleDateFormat(DateTimePicker.getFormat("dt"), Locale.getDefault())
editText.setText(sdf.format(it.calendar.time))
}.show()
// Open Time Picker only and set an EditText
DateTimePicker(this){
val sdf = SimpleDateFormat(DateTimePicker.getFormat("t"), Locale.getDefault())
editText.setText(sdf.format(it.calendar.time))
}.showTime()
// Use your own calendar object if you prefer to use your pre-configured calendar
val myCalendar = Calendar.getInstance()
myCalendar.set(Calendar.YEAR, 1995)
DateTimePicker(this, false, myCalendar){
val sdf = SimpleDateFormat(DateTimePicker.getFormat("d"), Locale.getDefault())
editText.setText(sdf.format(it.calendar.time))
}.show()

Don't understand how to correct mistake in datepicker code

I am not able to understand where am I doing mistake. I want to check it is a weekend or weekday. If it is weekend then it should prompt in the toast that it is a sunday or saturday weekend. I don't know what should I put in place of ??? mark. It should also display current date if it is weekend. Please, any one can help me. Thank you.

int dayOfWeek = c.get(Calendar.DAY_OF_WEEK);
if(dayOfWeek == 7 || dayOfWeek == 1) {
// as your requirement: you should display mesage they can not select the weekend" here
// then you set the value in datepickerdialog by current date
Toast.makeText(DateTimePickerActivity.this
, "You have selected weekend"
, Toast.LENGTH_SHORT).show();
}
}
}
}

Once you get your date you can do like this and get the day and proceed with your logic.
Calendar c = Calendar.getInstance();
c.setTime(yourDate);
int dayOfWeek = c.get(Calendar.DAY_OF_WEEK);

I think that your variable dayOfWeek is the same variable as the parameter dayOfMonth
The above code must work
public DatePickerDialog.OnDateSetListener pickerListener = new DatePickerDialog.OnDateSetListener() {
#Override
public void onDateSet(DatePicker view, int selectedYear,
int selectedMonth, int selectedDay) {
if (selectedDay == 1 || selectedDay == 7) {
Toast.makeText(DateTimePickerActivity.this
, "You have selected weekend"
, Toast.LENGTH_SHORT).show();
view.updateDate(selectedYear,selectedMonth,selectedDay);
}
}
};
