Date comparison to restrict user to select until current date

I have a DatePickerDialog in my app and I want the date selected by the user to be restricted until the current date. I am comparing the date selected from the DatePickerDialog with the newDate() and if the selected date is before, I am throwing an error. Please find the code as follows.
DatePickerDialog datePickerDialog = new DatePickerDialog(this,
new DatePickerDialog.OnDateSetListener() {
#Override
public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {
Calendar calendar = Calendar.getInstance();
calendar.set(year, monthOfYear, dayOfMonth);
SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MMM-yyyy");
String visitDate = dateFormat.format(calendar.getTime());
try {
Date appointDate = dateFormat.parse(visitDate);
Date currentDate = new Date();
if(appointDate.before(currentDate)){
appointmentDateInputLayout.setError("Date selected is not within range!");
}else{
appointmentDateEditText.setText(visitDate);
appointmentDateInputLayout.setError(null);
}
} catch (ParseException e) {
e.printStackTrace();
}
appointmentDateEditText.setText(visitDate);
}
}, mYear, mMonth, mDay);
datePickerDialog.getDatePicker().setMinDate(System.currentTimeMillis());
datePickerDialog.show();
But when I do this, I am getting an error for selecting today's date also. I want the user to allow the current date. What am I missing here?
Kindly help.

Look, the
Date currentDate = new Date() ;
allocates the date object at the time it was instantiated in the degree of Milliseconds so alternating the allocation and putting date object at the first of the code would give the very early time so the time that you take to choose visitdate would be eventually greater (after) so the number of Milliseconds in the currentDate will be less than number of Milliseconds in the Picked new Date

Try to compare with calendar getTime() method instead of current date.:
If(appointDate.before(calendar.getTime())

setMaxDate to DatePickerDialog

Hi I implemented a DatePickerDialog but I want to set range, I found setMinDate and setMaxDate, but I don't know how to put values. I want to set the calendar for a user of min age 18 and max age 100; I think it's about calculations into milliseconds.
final Calendar c = Calendar.getInstance();
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH);
int day = c.get(Calendar.DAY_OF_MONTH);
DatePickerDialog dpd = new DatePickerDialog(getActivity(), AlertDialog.THEME_DEVICE_DEFAULT_LIGHT, this, year, month, day);
dpd.getDatePicker().setMaxDate(max);
return dpd;
I don't know what value I have to put to max to do 2016 - 18.

Use this code, to set maximum date and minimum date from current date.
Calendar minCal = Calendar.getInstance();
minCal.set(Calendar.YEAR, minCal.get(Calendar.YEAR) - 100);
Calendar maxCal = Calendar.getInstance();
maxCal.set(Calendar.YEAR, maxCal.get(Calendar.YEAR) - 18);
dialog.getDatePicker().setMinDate(minCal.getTimeInMillis());
dialog.getDatePicker().setMaxDate(maxCal.getTimeInMillis());

I guess this is what you need:
final Calendar maxc = Calendar.getInstance();
int year = maxc.get(Calendar.YEAR);
maxc.set(Calendar.YEAR,year-18);
datePickerDialog.getDatePicker().setMaxDate(maxc.getTimeInMillis());
final Calendar minc = Calendar.getInstance();
int year = minc.get(Calendar.YEAR);
minc.set(Calendar.YEAR,year-100);
datePickerDialog.getDatePicker().setMinDate(minc.getTimeInMillis());
datePickerDialog.show();

how to set min date (using datepicker android ) two years back from instant time or day

On one of my app I'm using datepicker class to retrieve data form archive.
I need to set **Max and Min **. On DatePicker.Dialog,
i was able to set **Max to the current time ** however, i counted do for **Min **. if someone to help me i really appreciate it. thanks in advance!
I am looking set setMaxDate = to current year
and setMinDate = two years back from current year(current year -2)
NB: I triad to look if this question was already answered. But, i couldn't get one. all that i see is minData = current timedialog.getDatePicker().setMinDate(new Date().getTime()); which I am not looking for that. i want to set it to different year than the current.
here below part of my code:
// On Clike for Floting button with + signe
#Override
public void onClick(View v) {
switch (v.getId()) {
case imageButtonCalendar:
Calendar c = Calendar.getInstance();
final int[] mYear = {c.get(Calendar.YEAR)};
final int[] mMonth = {c.get(Calendar.MONTH)};
final int[] mDay = {c.get(Calendar.DAY_OF_MONTH)};
DatePickerDialog.OnDateSetListener pDateSetListener = new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {
mYear[0] = year;
mMonth[0] = monthOfYear;
mDay[0] = dayOfMonth;
et.setText(new StringBuilder()
// to set date in editext
.append(mDay[0]).append("/").append(mMonth[0] + 1)
.append("/").append(mYear[0]).append(" "));
}
};
DatePickerDialog dialog = new DatePickerDialog(getActivity(), pDateSetListener, mYear[0], mMonth[0], mDay[0]);
dialog.getDatePicker().setMaxDate(new Date().getTime());
dialog.getDatePicker().setMinDate(new Date().getTime(),-year);
dialog.show();
break;

You can use Calendar class :
Calendar cal = Calendar.getInstance()
cal.add(Calendar.DATE, -7);
System.out.println("Date = "+ cal.getTime());
Joda-time is the best Java library for Date.

Get the date after subtracting 2 years :
Calendar calendar = Calendar.getInstance();
calendar.add(Calendar.YEAR, -2);
dialog.getDatePicker().setMinDate(calendar.getTime()); // set min date

How to set maximum & minimum limits to date picker?

I am using date picker in my application couples of time. I want my date picker to show dates following some restrictions. I am using the below code:-
#Override
protected Dialog onCreateDialog(int id) {
switch(id) {
case DATE_PICKER_DIALOG:
datePickerDialogDateSetListener = new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker datePicker, int selectedYear, int selectedMonth, int selectedDate) {
year = selectedYear;
month = selectedMonth;
date = selectedDate;
activitySignUpDateEditText.setText(new StringBuilder().append(date));
activitySignUpMonthEditText.setText(new StringBuilder().append(month + 1));
activitySignUpYearEditText.setText(new StringBuilder().append(year));
}
};
return new DatePickerDialog(this, datePickerDialogDateSetListener, year, month, date);
default:
return null;
}
}
Somewhere i want the date picker to show maximum date 18 years back from current date & somewhere minimum date as the current date. I have searched a lot but doesn't found any satisfactory answer. I know about setMaxDate() & setMinDate() methods of date picker but when i tried with it, i am unable to set selected date on my edit text. any help would be appreciable. Thanks in advance.

You can try replacing this line:
return new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay);
By those:
DatePickerDialog dpDialog = new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay);
DatePicker datePicker = dpDialog.getDatePicker();
Calendar calendar = Calendar.getInstance();//get the current day
datePicker.setMaxDate(calendar.getTimeInMillis());//set the current day as the max date
return dpDialog;
in the same way you set the minimum date as well
DatePickerDialog dpDialog = new DatePickerDialog(this, pDateSetListener, pYear, pMonth, pDay);
DatePicker datePicker = dpDialog.getDatePicker();
Calendar calendar = Calendar.getInstance();//get the current day
datePicker.setMinDate(calendar.getTimeInMillis());//set the current day as the max date
return dpDialog;

For setting Max date as 18 years back, the following code snippet will do the job:
Calendar c = Calendar.getInstance();
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH);
int day = c.get(Calendar.DAY_OF_MONTH);
DatePickerDialog dateDialog = new DatePickerDialog(this, datePickerListener, year - 18, month, day);
//For setting minimum date as Current Date
//dateDialog.getDatePicker().setMinDate(c.getTimeInMillis ());
//For setting maximum date as 18 years back
c.set(year - 18, month, day);
dateDialog.getDatePicker().setMaxDate(c.getTimeInMillis());
return dateDialog;
As MaxDate can't be less than MinDate thus, MinDate should not be set as current date when MaxDate is set as 18 years back.
Hope it'll work for you.

Android Unable to update correct date when I select December as month from the picker

I am trying to update system time and date. Setting time works fine as i have system permissions in my app and application is signatured as system app also setting date works fine for Months Jan upto Nov, but when i select December as month it is setting month to Jan. this all is cause of i am adding 1 to month but in a case i dont add 1 it creates problem for every month. if I select Dec it is Showing Nov, if I am selecting Jan it works fine , When I select Feb it again selects Jan, If I select March it selects Feb. every time it is setting one month less than the selected one.
here is my code
private TimePickerDialog.OnTimeSetListener timePickerListener = new TimePickerDialog.OnTimeSetListener() {
#Override
public void onTimeSet(TimePicker view, int hourOfDay, int minutes) {
mHour = hourOfDay;
mMinute = minutes;
Calendar c = Calendar.getInstance();
c.set(mYear, mMonth+1, mDay, mHour, mMinute);
Intent intent = new Intent();
intent.setAction(Action);
intent.putExtra("time", c.getTimeInMillis());
getContext().sendBroadcast(intent);
}
};
private DatePickerDialog.OnDateSetListener datePickerListener = new DatePickerDialog.OnDateSetListener() {
#Override
public void onDateSet(DatePicker arg0, int arg1, int arg2, int arg3) {
mYear = arg1;
mMonth = arg2;
mDay = arg3;
mTimePickerDialog.show();
}
};
at the other end
long when = intent.getLongExtra("time", -1);
if (DEBUG)
Log.i(TAG, "Incoming time: " + when);
if (when / 1000 < Integer.MAX_VALUE) {
SystemClock.setCurrentTimeMillis(when);
}
Time time = new Time();
TvManager tvmng = TvManager.getInstance();
TimerManager timerMgr = null;
if(tvmng!=null)
timerMgr = tvmng.getTimerManager();
time.set(when);
try {
timerMgr.setClkTime(time, true);
} catch (TvCommonException e) {
e.printStackTrace();
}

Please correct the code as mentioned below.
Calendar c = Calendar.getInstance();
c.set(mYear, mMonth, mDay, mHour, mMinute);
remove the +1 you added after the month.
When you set the month in calender than it should be between 0 to 11 when you pass month +1 and your month is 11 then it will be 11+1 =12 and calender consider it as Jan not December.
When you use the date selected for the purpose of showing to user then you have to add month+1 so it will show exact month ,
But when you pass it to calender again for the purpose of storing users selection store it as it is without adding +1 if you added it before then make it month-1 and then add to calender object.
It should work as you expected.
Also look at my solution to over come the issue.
to get formatted date to display user
public static String getDate(Calendar calendar){
String formattedDate;
SimpleDateFormat format = new SimpleDateFormat("MMM dd,yyyy");
formattedDate=format.format(calendar.getTime());
return formattedDate;
}
To set date to calender instance after selecting date from date picker use it like below.
DialogFragment newFragment = new DatePickerDialogFragment() {
#Override
public void onDateSet(DatePicker datePicker, int year, int month, int day) {
super.onDateSet(datePicker, year, month, day);
Calender curDateInstance=Calender.getInstance();
curDateInstance.set(Calendar.YEAR, year);
curDateInstance.set(Calendar.MONTH, month);
curDateInstance.set(Calendar.DAY_OF_MONTH, day);
txtPickUpDate.setText(DateUtils.getDate(curDateInstance));
}
};
