Android: DatePicker and DatePicker Dialog

Question

I have this code here on the options menu

Dialog dialog = new Dialog(ScheduleActivity.this);
dialog.setTitle("Add Event");
dialog.setContentView(R.layout.add_even_on);
Button datePicker = (Button) dialog.findViewById(R.id.datePicker);
final DialogFragment dateFrag = new MyDatePicker();
    datePicker.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {
                dateFrag.show(getSupportFragmentManager(), "datePicker");               
            }
        });
dialog.show();

when, say "Add Event" on the option menu is clicked, a Dialog appears, with a button that shows a DatePickerDialog and beside it is a TextView that reflects the date chosen in the DatePickerDialog, here is the class I got from Androids Developer on how to use the DatePickerDialog.

class MyDatePicker extends DialogFragment implements DatePickerDialog.OnDateSetListener {
 int pYear;
 int pDay;
 int pMonth;

@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);
  }

  public void onDateSet(DatePicker view, int year, int month, int day) {
    pYear = year;
    pDay = day;
    pMonth = month;
  }
}

So my problem is that how do i get the Value in milleseconds when i click "Set" on the DatePickerDialog which in turn automatically closes it, and returns to my Dialog which contains the button which open the DatePickerDialog and a Textview which reflects watever date is chosen the DatePickerDialog... i wont show the one i chose inside the DatePickerDialog...

Here is a picture of what i mean,

So when i click on the Pick Date Button a DatePickerDialog box appears as seen on the next picture

and when i click set, i wanted to take into account the value in millseconds from that DatePickerDialog

Try this code it is definately work:

            final Calendar c = Calendar.getInstance();
            mYear = c.get(Calendar.YEAR);
            mMonth = c.get(Calendar.MONTH);
            mDay = c.get(Calendar.DAY_OF_MONTH);

            DatePickerDialog dpd = new DatePickerDialog(getActivity(),
                    new DatePickerDialog.OnDateSetListener() {

                        @Override
                        public void onDateSet(DatePicker view, int year,
                                int monthOfYear, int dayOfMonth) {

                            birth_Date.setText(dayOfMonth + "-"
                                    + (monthOfYear + 1) + "-" + year);
                        }
                    }, mYear, mMonth, mDay);
            dpd.show();

private static final int DATE_DIALOG_ID = 1;
private int year;
private int month;
private int day;
EditText editTextDate;
private String currentDate;
private Context context;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.addnewreminder);
    initialize();
    context = getApplicationContext();
    OnClickListener listenerDate = new OnClickListener() {

        @Override
        public void onClick(View arg0) {

            final Calendar c = Calendar.getInstance();
            year = c.get(Calendar.YEAR);
            month = c.get(Calendar.MONTH);
            day = c.get(Calendar.DAY_OF_MONTH);
            showDialog(DATE_DIALOG_ID);
        }
    };
    editTextDate.setOnClickListener(listenerDate);

}

private void initialize() {
    // TODO Auto-generated method stub

    editTextDate = (EditText) findViewById(R.id.editTextDate);

}


private void updateDisplay() {
    currentDate = new StringBuilder().append(day).append(".")
            .append(month + 1).append(".").append(year).toString();

    Log.i("DATE", currentDate);
}

OnDateSetListener myDateSetListener = new OnDateSetListener() {

    @Override
    public void onDateSet(DatePicker datePicker, int i, int j, int k) {

        year = i;
        month = j;
        day = k;
        updateDisplay();
        editTextDate.setText(currentDate);
    }
};



@Override
protected Dialog onCreateDialog(int id) {
    switch (id) {
    case DATE_DIALOG_ID:
        return new DatePickerDialog(this, myDateSetListener, year, month,
                day);
    }

You can try this code.. it will surely helpful to u.. No Doubt!

    protected Dialog onCreateDialog(int id) {

    Calendar c=Calendar.getInstance();
    int Sysday=c.get(Calendar.DAY_OF_MONTH);
    int Sysmonth=c.get(Calendar.MONTH);
    int Sysyear=c.get(Calendar.YEAR);

    int Sysmin=c.get(Calendar.MINUTE);
    int Syshour=c.get(Calendar.HOUR);


    switch (id) {
    case TIME_DIALOG:

        return new TimePickerDialog(this, myTimePicker , Syshour, Sysmin, false);

In XML add a TextView and a Button

<TextView
    android:id="@+id/searchText"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="TextView" />

<Button
    android:id="@+id/search"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Search" />

Add following code in java file

public class DatePickerDialogExample extends Activity {

    TextView txtDate;
    private int mYear, mMonth, mDay, mHour, mMinute;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);


        txtDate = (TextView) findViewById(R.id.searchText);
        Button search = (Button) findViewById(R.id.search);
        search.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // Process to get Current Date
            final Calendar c = Calendar.getInstance();
            mYear = c.get(Calendar.YEAR);
            mMonth = c.get(Calendar.MONTH);
            mDay = c.get(Calendar.DAY_OF_MONTH);

            // Launch Date Picker Dialog
            DatePickerDialog dpd = new DatePickerDialog(PrayTimeActivity.this,
                    new DatePickerDialog.OnDateSetListener() {

                        @Override
                        public void onDateSet(DatePicker view, int year,
                                int monthOfYear, int dayOfMonth) {
                            // Display Selected date in textbox
                            txtDate.setText(dayOfMonth + "-"
                                    + (monthOfYear + 1) + "-" + year);

                        }
                    }, mYear, mMonth, mDay);
                dpd.show();
            }
        });


    }

This is my helper function which get context and TextView as parameter and sets Date on that text view when user select a date:

        public static void showDate(final Context context, final TextView textView) {

    if (textView != null) {
        final Calendar myCalendar = Calendar.getInstance();
        DatePickerDialog.OnDateSetListener date = new DatePickerDialog.OnDateSetListener() {
            @Override
            public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                // TODO Auto-generated method stub
                myCalendar.set(Calendar.YEAR, year);
                myCalendar.set(Calendar.MONTH, monthOfYear);
                myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
                String myFormat = "MM/dd/yy"; // In which you need put here
                SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);
                //UIHelper.showLongToastInCenter(context, sdf.format(myCalendar.getTime()));
                textView.setText(sdf.format(myCalendar.getTime()));
            }

        };
        new DatePickerDialog(context, date, myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH)).show();
    } else {
        UIHelper.showLongToastInCenter(context, "Unable to show Date picker");
    }
}

Calendar c1 = Calendar.getInstance();    
int year = c1.get(Calendar.YEAR);
int month = c1.get(Calendar.MONTH);
int day = c1.get(Calendar.DAY_OF_MONTH);
DatePickerDialog.OnDateSetListener myDateListener  = new DatePickerDialog.OnDateSetListener() {

       public void onDateSet(DatePicker arg0, int arg1, int arg2, int arg3) {
                   if(arg0.isShown()){

                                     //do further code here

                              }
                            }

                          };
        DatePickerDialog dp = new DatePickerDialog(YourActivity.this, myDateListener, year, month, day);
        dp.show();
