Check the date and time which you have passed to the datepicker dialog, you need to pass current date and time to get updated dialog — Madhu, Oct 01 '15 at 05:05
date picker is year month day, you have it back to front. Check the order of the constructor arguements. http://developer.android.com/intl/ko/reference/android/app/DatePickerDialog.html#DatePickerDialog%28android.content.Context,%20android.app.DatePickerDialog.OnDateSetListener,%20int,%20int,%20int%29 — Breavyn, Oct 01 '15 at 05:06

As per the docs for the constructor:

public DatePickerDialog (
    Context context,
    DatePickerDialog.OnDateSetListener callBack,
    int year,
    int monthOfYear,
    int dayOfMonth)

It has to be year, month, day, not day, month, year as you have it.

As for the problem of your time being out by an hour, the first thing I'd be looking at is the default timezone. It's almost invariably something to do with that when the times are out by some exact number of hours.

It will either be because you're in a different timezone from your default, or you have daylight savings incorrectly configured.

To figure out your timezone, have a look at this question.

friend thank you. Please, could you check what is wrong in my time code. It shows me one hour less than the current time. Thanks – J. Vyas Oct 01 '15 at 05:23
@J.Vyas, see the update, along with a look which should help in establishing whether the timezone is the problem. – paxdiablo Oct 01 '15 at 05:32

Try this:

private void showDatePickerDialog() {
        DatePickerDialog datepickerdialog = null;
        datepickerdialog = new DatePickerDialog
                (
                        this,
                       /* new DatePickerDialog.OnDateSetListener() {
                            @Override
                            public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                            } },*/
                        this,
                        year,
                        month,
                        day
                );
        datepickerdialog.show();
    }

Thank you.It is showing current date. but still time is showing wrong. please, could you guide me where is my mistake in the code thanks – J. Vyas Oct 01 '15 at 05:19
try removing Locale.getDefault() from Calendar calendar = Calendar.getInstance(Locale.getDefault()); – Aakash Oct 01 '15 at 05:37
Hi friend, It displays same time. – J. Vyas Oct 01 '15 at 05:44
i have not asked to put it in comment, just remove Locale.getDefault() from inside the bracket – Aakash Oct 01 '15 at 05:45
sorry I got it and remove only Locale.getDefault() only. but still it shows same time – J. Vyas Oct 01 '15 at 05:49
can you try using Calendar.HOUR_OF_DAY – Aakash Oct 01 '15 at 05:53
I have used that one as well just 2 min ago. still no change – J. Vyas Oct 01 '15 at 05:56
I have daylight saving. so does it affect? – J. Vyas Oct 01 '15 at 05:58
