#Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
dateET.setText(dayOfMonth + "/" + monthOfYear + "/" + year);
}
I want to avoid user setting date past to current date.
So, is there a way i can get the long timestamp (may be 12:00 A.M of the date set), so that i can compare it with the current timestamp and if it is less, the date will be set to default(current date + 3 days).
Thank You
You have to do it yourself:
Calendar calendar = new GregorianCalendar(year, monthOfYear, dayOfMonth);
calendar.getTimeInMillis();

When i press the button to display the DatePickerDialog, the dialog displays one month greater. For instance, if i initiate with the current date like this(with the DateTime of joda library):
DateTimeZone zone = DateTimeZone.forID("Europe/Athens");
DateTime dt = new DateTime(zone);
int year = dt.getYear();
int month = dt.getMonthOfYear();
int day = dt.getDayOfMonth();
which is 07/08/2014, the date dialog displays one month greater 07/09/2014.
I do not understand why this happens.
The fragment which represents the datePickerFragment is:
#SuppressLint("ValidFragment")
public class DatePickerFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener{
#SuppressLint("ValidFragment")
TextView txtDate;
GlobalData appState;
public DatePickerFragment(TextView txtDate) {
super();
this.txtDate = txtDate;
}
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the current date as the default date in the picker
DateTimeZone zone = DateTimeZone.forID("Europe/Athens");
DateTime dt = new DateTime(zone);
int year = dt.getYear();
int month = dt.getMonthOfYear();
int day = dt.getDayOfMonth();
Log.i("DatePickerFragment day month year", day +" "+ month + " "+ year + "");
// Create a new instance of DatePickerDialog and return it
return new DatePickerDialog(getActivity(), this, year, month, day);
}
public void onDateSet(DatePicker view, int year, int month, int day) {
appState.setDateUserFrom(year, month, day);
Log.i("Date day month yerar", "Date changed." + day+" " + month + " " +year);
txtDate.setText(new StringBuilder().append(day)
.append("-").append(month).append("-").append(year)
.append(" "));
}
}
DatePickerDialog takes monthOfYear that is 0 to 11 [0 for Jan... 11 for Dec], and your DateTime returns 1 to 12. So you need to do -1 with month value.
Use this:
return new DatePickerDialog(getActivity(), this, year, month - 1, day);
public Dialog onCreateDialog(Bundle savedInstanceState) {
// Use the current date as the default date in the picker
DateTimeZone zone = DateTimeZone.forID("Europe/Athens");
DateTime dt = new DateTime(zone);
int year = dt.getYear();
int month = dt.getMonthOfYear()-1;
int day = dt.getDayOfMonth();
Log.i("DatePickerFragment day month year", day +" "+ month + " "+ year + "");
// Create a new instance of DatePickerDialog and return it
return new DatePickerDialog(getActivity(), this, year, month, day);
}
Month in date picker starts with zero. So you should subtract one from the getMonthOfYear() to set it on datepicker.
I am pretty sure the reason behind this is because the Android DatePickerDialog expects 0 based month values. Jodatime return them as you would expect it (more human friendly). So just subtract 1 from the month.
Just to clarify, most date functions/libraries are designed with 0 based month values by default. The exception is where explicitly noted, or third party libraries like Jodatime, which make working with date stuff a joy.
Just a guess. Joda month starts at 1 for january but java date at 0? So if you use the current date init with joda the date picker will show the wrong month. Easy solution:
month = dt.getMonthOfYear() - 1;
Try this hope it's worked:
DateTimeZone zone = DateTimeZone.forID("Europe/Athens");
DateTime dt = new DateTime(zone);
int year = dt.getYear();
int month = dt.getMonth();
int day = dt.getDayOfMonth();
OR
DateTimeZone zone = DateTimeZone.forID("Europe/Athens");
DateTime dt = new DateTime(zone);
int year = dt.getYear();
int month = dt.getMonthOfYear() - 1;
int day = dt.getDayOfMonth();
I am using the example from the documentation.
From the method
public void onDateSet(DatePicker view, int year, int month, int day) {
// Do something with the date chosen by the user
}
I want the string "Mon, Sep 14, 2014". How do I get it? Ideally I really want "Mon, Sep 14, 2014 10:30PM" but I can't find a combined date and time picker.
Here ya go date time combined.
This is no meant to be mean just that you said you were having trouble finding one.
how to find it : http://bit.ly/1doSxEf
Which one I use:
https://github.com/bendemboski/DateSlider
// try this way
public void onDateSet(DatePicker view, int year,int monthOfYear, int dayOfMonth) {
Time chosenDate = new Time();
chosenDate.set(dayOfMonth, monthOfYear, year);
long dt = chosenDate.toMillis(true);
CharSequence strDate = DateFormat.format("KKK MMM dd,yyyy", dt);
// mow use strDate..
}
I'm trying to get the actual month from the Calendar using the following:
Calendar c = Calendar.getInstance();
String time = String.valueOf(c.get(Calendar.MONTH));
According the system settings "Settings --> Date & Time" actual month is 10 while get(Calendar.MONTH) returns 09.
Keep in mind that months values start from 0, so October is actually month number 9.
http://docs.oracle.com/javase/1.4.2/docs/api/java/util/Calendar.html#MONTH
Calendar.MONTH returns month which is zero based that is why it is giving 1 less than actual month
Add 1 to get correct value
String time = String.valueOf(c.get(Calendar.MONTH)+1);
Calendar.MONTH
returns
0 for 1st month (jan)
1 for 2nd month (feb)
.
.
11 for 12th month (dec)
Docs
So change your code to
String time = String.valueOf(c.get(Calendar.MONTH)+1);// added 1
Calendar.MONTH value starts from 0 to 11 not 1 to 12.
You may check the value of Calendar.JANUARY is 0 not 1.
Refer: http://developer.android.com/reference/java/util/Calendar.html#JANUARY
I suggest trying
#Override
public void onSelectedDayChange(CalendarView view, int year, int month, int day) {
Toast.makeText(getApplicationContext(), month+1 + "/" + day + "/" + year, Toast.LENGTH_SHORT).show();
calDate = month+1 + "/" + day + "/" + year; }
});
use this
public void DateDialog(){
DatePickerDialog.OnDateSetListener listener=new DatePickerDialog.OnDateSetListener() {
#Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth)
{
int Month;
Month=monthOfYear+1;
fromDate.setText(year + "-" + Month + "-" + dayOfMonth);
}};
DatePickerDialog dpDialog=new DatePickerDialog(getActivity(), listener, year, month, day);
dpDialog.getDatePicker().setMinDate(mcalendar.getTimeInMillis());
dpDialog.show();
}
I'd like to get day, month and year values for save to db. These are my codes:
Declaretions:
private TextView tv_purchase_date;
private Button mPickDate;
private int mYear;
private int mMonth;
private int mDay;
OnClickListener listener_show_dlg = null;
OnDateSetListener listener_mdate_display = null;
Event Code:
listener_show_dlg = new OnClickListener() {
public void onClick(View v) {
Calendar cal=Calendar.getInstance();
DatePickerDialog datePickDlg = new DatePickerDialog(
ItemsAddActivity.this,
listener_mdate_display,
cal.get(Calendar.YEAR),
cal.get(Calendar.MONTH),
cal.get(Calendar.DAY_OF_MONTH)
);
datePickDlg.show();
};
};
listener_mdate_display = new OnDateSetListener() {
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
mMonth = month;
mYear = year;
mDay = dayofMonth;
tv_purchase_date.setText(dayOfMonth + "/" + monthOfYear + "/" + year);
}
};
}
I try to store mMonth, mYear and mDay values in db. What is the best store type? as integer or as string??
I store in the DB one number that represents the date. It is the number of seconds that have passed since the beginning of the modern era (Jan 1, 1970.) From the Date Picker, you can get the M D Y values like this:
datePickerListener = new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int yearOfYear,
int monthOfYear, int dayOfMonth) {
// the user has picked these values
year = yearOfYear;
month = monthOfYear;
day = dayOfMonth;
Then, I turn these into a single Date object like this.
Calendar cal = new GregorianCalendar(year, month, day);
Date dateOfGames = cal.getTime();
DateFormat df = DateFormat.getDateInstance(DateFormat.LONG);
String cs = df.format(dateOfGames);
changeDateButton.setText(cs); // update the interface
}
};
before I put it in the DB, I turn it into a numebr of seconds like this:
long seconds = date.getTime() / 1000; // this is the date in seconds since the start of the epoch
....
when I take that single number of seconds out of the DB, and want it to be a Date object again, I do this:
date = new Date(seconds * 1000); // converting seconds to a Date object
You can use a DateFormat object to display the date object how you like to see it.
I know this is awkward. Since SQLite doesn't allow you to store a Date, the answer is going to be awkward. Perhaps there is a cleaner way than this, and others will recommned something. :)
I struggled with this issue for a while. I don't konw of anything better than this.
I stored the date in the DB as a single long int. It is pretty easy to convert your Date to the number of seconds since the epoch (Jan 1, 1970), and it is also easy to convert the number of seconds into a Date object.
You need to be careful with seconds and milliseconds.
date = new Date(seconds * 1000); // converting seconds to a Date
seconds = date.getTime() / 1000; // this is the date in seconds since the start of the epoch
// Use Greg calendar to get a Date object from day, month, year
Date dateOfGames = new GregorianCalendar(year, month, day).getTime();
Does that help at all?
I created sqllite table with this sql string:
create table items (id INTEGER PRIMARY KEY AUTOINCREMENT, pdate DATE)
I writed some methods to convert date:
public String date_to_str(Date date) {
String pattern = "dd.MM.yyyy";
SimpleDateFormat dateFormat = new SimpleDateFormat(pattern);
Log.d(_watcher_name, "date_to_str" + dateFormat.format(date));
return dateFormat.format(date);
}
public Date mdy_to_date (int day, int month, int year) {
Calendar cal = new GregorianCalendar(year, month, day);
return cal.getTime();
}
How to restrict date picker from accepting current and future dates in android i am using google api...any idea..?
Since API level 11 there is a method for that:
DatePicker.setMaxDate(long maxDate)
If it has to work in previous versions, use this method:
public void init(int year, int monthOfYear, int dayOfMonth, DatePicker.OnDateChangedListener onDateChangedListener)
You could pass your own OnDateChangedListener which "resets" invalid dates to the newest valid one:
DatePicker picker = ...
int year = ...
int monthOfYear = ...
int dayOfMonth = ...
picker.init(year, monthOfYear, dayOfMonth, new DatePicker.OnDateChangedListener() {
#Override
public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
// check if current date is OK
boolean dateOk = ...
if (!dateOk) {
// correct the date, but be sure the corrected date is OK
// => otherwise you might get endless recursion
year = ...
monthOfYear = ...
dayOfMonth = ...
// update the date widget with the corrected date values
view.updateDate(year, monthOfYear, dayOfMonth);
}
}
});
