getdate from datepicker android

Question

I want to get date from datepicker widget in android I have tried with this

Date date1= (Date) new Date
   (dpBirthDate.getYear(), dpBirthDate.getMonth(), dpBirthDate.getDayOfMonth());
date1  = (Date) new SimpleDateFormat("yyyy-MM-dd").parse(date1.toString());

But I get a date like this mon 7 dec 2011 time ... and all I want to get is the yyyy-MM-dd format to store it in the database.

I tried also to concat the year-month-day like this but the problem is for example today 2011-12-7 the day should be 07 to be valid

Could you help me please.

Solution 1

I use this:

    /**
 * 
 * @param datePicker
 * @return a java.util.Date
 */
public static java.util.Date getDateFromDatePicker(DatePicker datePicker){
    int day = datePicker.getDayOfMonth();
    int month = datePicker.getMonth();
    int year =  datePicker.getYear();

    Calendar calendar = Calendar.getInstance();
    calendar.set(year, month, day);

    return calendar.getTime();
}

Solution 2

You should use SimpleDateFormat.format to convert that Date object to a String, like this

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
String dateString = sdf.format(date1);

I think you just had it backwards. You need to use format to go from Date to String, and parse to go from a String to a Date.

I know this is old but i struggled to find it. So for posterity

Scenario: A View needs the date in yyyy-mm-dd

    date_field = (EditText)findViewById(R.id.input_date);
        date_field.setFocusable(false); // disable editing of this field
        date_field.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(final View v) {
                chooseDate();
            }
        });

 private void chooseDate() {
        final Calendar calendar = Calendar.getInstance();
        final int year = calendar.get(Calendar.YEAR);
        final int month = calendar.get(Calendar.MONTH);
        final int day = calendar.get(Calendar.DAY_OF_MONTH);
        DatePickerDialog datePicker =
            new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {
                @Override
                public void onDateSet(final DatePicker view, final int year, final int month,
                                      final int dayOfMonth) {

                    @SuppressLint("SimpleDateFormat")
                    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
                    calendar.set(year, month, dayOfMonth);
                    String dateString = sdf.format(calendar.getTime());

                    date_field.setText(dateString); // set the date
                }
            }, year, month, day); // set date picker to current date

        datePicker.show();

        datePicker.setOnCancelListener(new DialogInterface.OnCancelListener() {
            @Override
            public void onCancel(final DialogInterface dialog) {
                dialog.dismiss();
            }
        });
    }

Hope this helps someone

changed the code like this Date date1= (Date) new Date(dpBirthDate.getYear(), dpBirthDate.getMonth(), dpBirthDate.getDayOfMonth()); dates =new SimpleDateFormat("yyyy-MM-dd").format(date1); and what I got 3911-12-07 whats wrong

[skynet]

Well then check what the year of the Date object is before you pass it in

[Aymen Taarit]

how can I fix the Date format please help ! I always get the date strats with 3911

[skynet]

Then you are creating the Date object incorrectly. As I said, you should debug what the value actually is. If you look at the documentation of Date you see that the year you pass in must be "the year minus 1900", so that is probably your error. Java's Date object has to be handled with care.

[Aymen Taarit]

thank you now its clear I should do 3911 -1900 to get the proper year 2011

This largely worked for me, except I needed to define the DatePicker as a android.widget.DatePicker instead. Thanks :)

If you are using Kotlin, you can do it even in a more elegant way.
