I need to show this date picker dialog within my popup. This popup have validations for fields. Is it possible to add date picker here? How will I implement the interface implements DatePickerDialog.OnDateSetListener in a Dialog popup screen.

Yes you can open a date picker from a alertdialog pop up on which field of your popup you want to open date picker — Sandeep dhiman, May 19 '17 at 07:20

Make your editText global for which you want to open the DatePicker dialog.

age = (EditText) dialog.findViewById(R.id.editText6);

Where age is declared in Activity or Fragment.

Now in setOnClickListener, you can open the DatePicker normally.

What happens if dialog is dynamic. Meaning I need to set different dialog contents within the for loop?. – Sudhakar May 19 '17 at 07:39

Do you have the reference of your dialog. Because you would need that to set the selected date in your dialog. – schinj May 19 '17 at 07:50

    dialog = new Dialog(TravellerDetailsActivity.this);
    dialog.setContentView(R.layout.custom_dialog);

    dob = (EditText) dialog.findViewById(R.id.editText7);

    dob.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            vv = v;
            Calendar now = Calendar.getInstance();
            DatePickerDialog dpd = DatePickerDialog.newInstance(
                    TravellerDetailsActivity.this,
                    now.get(Calendar.YEAR),
                    now.get(Calendar.MONTH),
                    now.get(Calendar.DAY_OF_MONTH)
            );
            dpd.show(TravellerDetailsActivity.this.getFragmentManager(), "Datepickerdialog");

        }
    });

@Override
public void onDateSet(DatePickerDialog view, int year, int monthOfYear, int dayOfMonth) {
    String date = year + "-" + (++monthOfYear) + "-" + dayOfMonth;
    dob.setText(date);
}

Keep dialog and edit text global and use the reference to set date. — Sudhakar, May 19 '17 at 08:23
