I have the following widget in my app. Where it says set date is it possible to replace this with the day of week, day of month, month and year. eg wed 07 Nov 2012?
I'm running Android 4 on htc whereas i know if i run the same code on Android 2.3.3 the the date is displayed how i want it.
.[update1]
#Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case DATE_DIALOG_ID:
// set date picker as current date
return new DatePickerDialog(this,2 ,datePickerListener, year, month, day);
}
return null;
}
.[update2]
#Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case DATE_DIALOG_ID:
// set date picker as current date
final DateFormat df = DateFormat.getDateInstance(0);
final Calendar mCal = Calendar.getInstance();
// Create a date picker dialog
DatePickerDialog datePickerDialog = new DatePickerDialog(this,2,datePickerListener, year, month, day){
#Override
public void onDateChanged(DatePicker view, int year,int month, int day){
mCal.set(Calendar.YEAR, year);
mCal.set(Calendar.MONTH, month);
mCal.set(Calendar.DAY_OF_MONTH, day);
setTitle(df.format(mCal.getTime()));
}
};
return datePickerDialog;
//return new DatePickerDialog(this,2 ,datePickerListener, year, month, day);
}
return null;
}
Yes. I did it with following code.. You will have to change according to your requirement.
dPicker.init((previouslyEnteredDate.getYear() + 1900),
previouslyEnteredDate.getMonth(),
previouslyEnteredDate.getDate(), null);
If you just want to initialize it with the current date as a reminder of what today is (or at least don't need it to change as the user interacts with the picker) you can do it by creating a temporary variable and calling the setTitle(CharSequence) method on it (since DatePickerDialog extends AlertDialog)
for example:
case DATE_DIALOG_ID:
// set date picker as current date
DatePickerDialog dpd = new DatePickerDialog(this, 2, datePickerListener,
year, month, day);
dpd.setTitle("Today is: " + year + "-" + (month + 1) + "-" + day);
return dpd;
Okay, I got a bit lazy with the formatting, there, obviously, but I hope you get the basic idea.
If you want the title to update as they are changing the date on the picker, that gets more involved, but I can't imagine that's what you're going for (unless the point is to see the day of the week in context as they are changing it?). If it is, let me know and I'll elaborate.

I'm experiencing a weird visual bug on new DatePickerDialog of Android widgets. I need to set a dialog's selectable date range as 1 month but it shouldn't also select a date from the future. Logic works as expected but the visuals have some sort of bug. Here is how it looks:
Note that the "5" is disabled, I cannot select it. However, it looks as selectable. What should I do to solve this issue? Any help is appreciated, thanks. (Today's day of month is also 5, I assume this bug comes from there.)
Edit: This is how I create the dialog.
#SuppressLint("ValidFragment")
public static class DateDialog extends DialogFragment implements DatePickerDialog.OnDateSetListener
{
private static final long MONTH = 2592000000L;
#Override
public Dialog onCreateDialog(Bundle savedInstanceState)
{
// Use previous selected date in the date picker
final Calendar c = Calendar.getInstance();
c.setTimeInMillis(DateUtils.getAtTimeTimestamp(startDate));
int year = c.get(Calendar.YEAR);
int month = c.get(Calendar.MONTH);
int day = c.get(Calendar.DAY_OF_MONTH);
DatePickerDialog dialog = new DatePickerDialog(getActivity(), R.style.AppTheme_DialogTheme, this, year, month, day);
Date date = new Date(); // get current time
// get target maximum date which can be 1 month above
long targetDateTime = DateUtils.getAtTimeTimestamp(startDate) + MONTH;
if (date.getTime() < targetDateTime)
dialog.getDatePicker().setMaxDate(date.getTime()); // now because it can't be future
else
dialog.getDatePicker().setMaxDate(targetDateTime); // should also be one month above from the start date.
dialog.getDatePicker().setMinDate(DateUtils.getAtTimeTimestamp(startDate));
return dialog;
}
#Override
public void onDateSet(DatePicker datePicker, int i, int i1, int i2)
{
// logic between date selections
}
}
DateUtils.getAtTimeTimestamp(String date) basically converts a string to long integer that is time in milliseconds.
I want to put the limit on date so that user can not pick date more then that, for example if today is 1 January then User should not be able to select more then 7 dates , I mean he can not select 9 January. I also want him not to select the month and year. So I am putting a limit to set his task in one week.
what I have done so far is showing the date picker fragment and setting current date in it. the code in my main activity goes like this:
etSelectDate.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
DialogFragment datePickerFragment = new DatePickerFragment() {
#Override
public void onDateSet(DatePicker view, int year, int month, int day) {
Log.d("Date Change", "onDateSet");
Calendar c = Calendar.getInstance();
c.set(year, month, day);
DateFormat df = DateFormat.getDateInstance();
etSelectDate.setText(df.format(c.getTime()));
//nextField.requestFocus(); //moves the focus to something else after dialog is closed
}
};
datePickerFragment.show(MainActivity.this.getSupportFragmentManager(), "datePicker");
}
});
and date picker fragment class goes like this :
public static class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener{
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the current date as the default date in the picker
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);
// Create a new instance of DatePickerDialog and return it
return new DatePickerDialog(getActivity(), this, year, month, day);
}
#Override
public void onDateSet(DatePicker view, int year, int month, int day) {
//blah
}
}
till then its is working fine , but I do not know how to put the limit on date and rest of the months and year should be non Select able . I have seen many link such as like this , but I do not understand How can I do that and also there is nothing helpful on android site.
So please help me , How can I put limit of seven days only
Update
Through your replies I know how to set the max date in calender , so As I want to set the max date 7 days ahead of current date , I am still not getting it. the method I read so far is :
pickerDialog.getDatePicker().setMaxDate(new Date().getTime());
It is setting the current date as maximum, but How can I add 7 days ahead in it since it is Date object ? please help
You have the setMinDate(long) and setMaxDate(long) methods at your disposal. Both of these will work on API level 11 and above. Since you are using a DatePickerDialog, you need to first get the underlying DatePicker by calling the getDatePicker() method.
dpdialog.getDatePicker().setMinDate(minDate);
dpdialog.getDatePicker().setmaxDate(maxDate);
Source :Set Limit on the DatePickerDialog in Android?
You can calculate the minDate by using,
Date today = new Date();
Calendar c = Calendar.getInstance();
c.setTime(today);
c.add( Calendar.MONTH, -6 ) // Subtract 6 months
long minDate = c.getTime().getTime() // Twice!
Updated :
Replace the below line
return new DatePickerDialog(getActivity(), this, year, month, day);
with
// Create a new instance of DatePickerDialog and return it
DatePickerDialog pickerDialog = new DatePickerDialog(getActivity(), this, year, month, day);
pickerDialog.getDatePicker().setMaxDate(maxDate);
pickerDialog.getDatePicker().setMinDate(minDate);
return pickerDialog;
In some cases, when you set maximum date with a date without hours and minutes, you won't be able to select the maximum date you set.
For instance
Calendar maxDate = Calendar.getInstance();
maxDate.set(Calendar.DAY_OF_MONTH, day + 5);
maxDate.set(Calendar.MONTH, month);
maxDate.set(Calendar.YEAR, year);
datePickerDialog.getDatePicker().setMaxDate(maxDate.getTimeInMillis());
With the code block above, you can not click to your maxDate.
But if you add hours and minutes to like;
maxDate.set(Calendar.HOUR, 23);
maxDate.set(Calendar.MINUTE, 59);
to your maxDate, your last date will be clickable
by using
setMinDate and setMaxDate
MinDate
MaxDate
try this
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 or put yore date in miliseconds.
datePicker.setMinDate(calendar.getTimeInMillis());//set the current day as the min date or put your date in mili seconds format
return dpDialog;
How to show 1980 as initial Year in DatePicker dialog, still i am getting initial date as current date
see my code below, and let me know where i have to do changes in my code
#Override
protected Dialog onCreateDialog(int id) {
switch (id) {
case DIALOG_DATE:
return new DatePickerDialog(this, new OnDateSetListener() {
#Override
public void onDateSet(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {
dateTime.set(year, monthOfYear, dayOfMonth);
editDate.setText(dateFormatter
.format(dateTime.getTime()));
}
}, dateTime.get(Calendar.YEAR),
dateTime.get(Calendar.MONTH),
dateTime.get(Calendar.DAY_OF_MONTH));
}
return null;
That is because the last 3 parameters on the DatePickerDialog constructor are the date to be shown initially in the DatePicker. You are setting the dateTime variable to the current day with
private Calendar dateTime = Calendar.getInstance();
So you must set your dateTime variable to the correct date you want to be shown on the first run. In your OnCreate() method do this
dateTime.set(1980, Calendar.JANUARY , 1);
Now your DatePicker should show the correct value on the first run and since you set the dateTime variable in the callback it should set the correct previous value if the user opens up the dialog again.
Hi every one thanks in advance..
I have requirement in my App that I have a Date Picker to set the date. Now I want to restrict the Date Picker to set the date above System current dates but not below to the System current date. How....?
Can any one help me out from this.... And How to validate the System current date with the Date Picker Date.
In this case you can extend DatePickerDialog and make your own implementation of OnDateChanged, which is called everytime that the date changes and you get as parameters the DatePicker, and the new year, month and day values, so you can check if that date is past and in that case throw the error (with a Toast or whatever) and call DatePicker.updateDate() to set a correct value (so that DatePicker is allways in a consistent state).
Also, you can call to DatePicker.init(year, monthOfYear, dayOfMonth, onDateChangedListener); then you can pass a
onDateChangedListener implementation without having to extend DatePickerDialog.
EDIT: (I never try this but I think it can done your work..)
DatePicker's
setMinDate(long minDate)
Sets the minimal date supported by this NumberPicker in milliseconds since January 1, 1970 00:00:00 in getDefault() time zone.
Example:
DatePickerDialog dialog = new DatePickerDialog(this, mDateSetListener, cyear, cmonth, cday);
dialog.getDatePicker().setMinDate(new Date());
Use setMinDate function of CalendarView class. Here you can set your date in milli seconds. To prevent future dates use setMaxDate
Use getDatePicker to get the datepicker and set calendarView as told above.
private int myear; //Declare these three variables in MainActivity and call showDialog(1)
private int mmonth;
private int mday;
final Calendar myCalendar= Calendar.getInstance();
private void setCurrentDateOnView() { //Call this method before showDialog
myear = myCalendar.get(Calendar.YEAR);
mmonth = myCalendar.get(Calendar.MONTH);
mday = myCalendar.get(Calendar.DAY_OF_MONTH);
}
protected Dialog onCreateDialog(int id) {
switch (id) {
case 1:
DatePickerDialog startDate = new DatePickerDialog(this, datePickerListener, myear,mmonth,
mday){
#Override
public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth)
{
}
};
myCalendar.set(myear, mmonth, mday);
long startTime = myCalendar.getTimeInMillis();
startDate.getDatePicker().setMinDate(startTime - 1000);
return startDate;
}
return null;
}
in my application i have to date picker as From date and To date. I am using onCreateDialog() method. So first time i am selecting the dates from date picker and putting them in the edit text. then when again i am selecting the date from the date picker, in the date picker it is showing the date which i already selected. But if i move to other search in the same screen(Activity) and try to pick the date from date picker, date picker still is showing the previous date. not the current date.
protected Dialog onCreateDialog(int id) {
final Calendar c = Calendar.getInstance();
switch (id) {
case DATE_DIALOG_ID1:
return new DatePickerDialog(this, mDateSetListener, c.get(Calendar.YEAR),
c.get(Calendar.MONTH), c.get(Calendar.DAY_OF_MONTH));
case DATE_DIALOG_ID2:
return new DatePickerDialog(this, mDateSetListener2, c.get(Calendar.YEAR),
c.get(Calendar.MONTH), c.get(Calendar.DAY_OF_MONTH));
}
return null;
}
May be you can try writing your question clearly once again, but to my understanding of your question you might want to look at your onDateChanged() callback method. I assume you have a updateDialog() method inside this onDateChanged(), you might want to check that method for err's.
I suppose you looked this link where they showed how to use a date picker http://developer.android.com/resources/tutorials/views/hello-datepicker.html
good luck
For the 2nd question you asked about mixup in from and to date dialog
From what you are saying, I think there something like a small error like
1) R.id.datepicker2 being used in place of R.id.datepicker1
or
2) having mixs up in onDateChangedListener(). I am sure there is better way to do it, but try checking whether you have like this below 2 different listeners
final Calendar c = Calendar.getInstance();
mYear = c.get(Calendar.YEAR);
mMonth = c.get(Calendar.MONTH);
mDay = c.get(Calendar.DAY_OF_MONTH);
DatePicker fromDatePicker = (DatePicker) findViewById(R.id.datePicker1);
datePicker.init(mYear, mMonth, mDay, new OnDateChangedListener() {
#Override
public void onDateChanged(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {
//things you want to happen when datepicker1 is changed in your case the From date field
}
});
DatePicker toDatePicker = (DatePicker) findViewById(R.id.datePicker1);
datePicker.init(mYear, mMonth, mDay, new OnDateChangedListener() {
#Override
public void onDateChanged(DatePicker view, int year,
int monthOfYear, int dayOfMonth) {
//things you want to happen when datepicker2 is changed in your case the To date field
}
});
