Solution 1

After Brain Storming half a day i have found this solution this may help other having such scenarios

My Custom class for date Picker is Following that will update the date in title every time user change month/year

class CustomDatePickerDialog extends DatePickerDialog implements OnDateChangedListener {

private DatePickerDialog mDatePicker;

@SuppressLint("NewApi")
public CustomDatePickerDialog(Context context,int theme, OnDateSetListener callBack,
        int year, int monthOfYear, int dayOfMonth) {
    super(context, theme,callBack, year, monthOfYear, dayOfMonth);
    mDatePicker = new DatePickerDialog(context,theme,callBack, year, monthOfYear, dayOfMonth);

    mDatePicker.getDatePicker().init(2013, 7, 16, this);

    updateTitle(year, monthOfYear);

}
public void onDateChanged(DatePicker view, int year,
        int month, int day) {
    updateTitle(year, month);
}
private void updateTitle(int year, int month) {
    Calendar mCalendar = Calendar.getInstance();
    mCalendar.set(Calendar.YEAR, year);
    mCalendar.set(Calendar.MONTH, month);
//       mCalendar.set(Calendar.DAY_OF_MONTH, day);
        mDatePicker.setTitle(getFormat().format(mCalendar.getTime()));

}   

public DatePickerDialog getPicker(){

    return this.mDatePicker;
}
    /*
     * the format for dialog tile,and you can override this method
     */
public SimpleDateFormat getFormat(){
    return new SimpleDateFormat("MMM, yyyy");
};   
}

and the following is the code that will hide the day and its spinner from the date picker dialog

CustomDatePickerDialog dp = new CustomDatePickerDialog(context, android.R.style.Theme_Holo_Light_Dialog,  datePickerListener, year, month, day);

               DatePickerDialog obj = dp.getPicker();
              try{
                         Field[] datePickerDialogFields = obj.getClass().getDeclaredFields();
                         for (Field datePickerDialogField : datePickerDialogFields) { 
                             if (datePickerDialogField.getName().equals("mDatePicker")) {
                                 datePickerDialogField.setAccessible(true);
                                 DatePicker datePicker = (DatePicker) datePickerDialogField.get(obj);
                                 Field datePickerFields[] = datePickerDialogField.getType().getDeclaredFields();
                                 for (Field datePickerField : datePickerFields) {
                                    if ("mDayPicker".equals(datePickerField.getName()) || "mDaySpinner".equals(datePickerField
                                      .getName())) {
                                       datePickerField.setAccessible(true);
                                       Object dayPicker = new Object();
                                       dayPicker = datePickerField.get(datePicker);
                                       ((View) dayPicker).setVisibility(View.GONE);
                                    }
                                 }
                              }

                           }
                         }catch(Exception ex){
                         }
              obj.show();

Solution 2

Simply way - just to hide NumberPicker in datePickerDialog here is code from my project

public class SelectDateFragment extends DialogFragment implements DatePickerDialog.OnDateSetListener {
    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {

        final Calendar c = Calendar.getInstance();

        DatePickerDialog dialog = new DatePickerDialog(getActivity(), this, c.get(Calendar.YEAR),
                c.get(Calendar.MONTH), c.get(Calendar.DAY_OF_MONTH));

        dialog.getDatePicker().setSpinnersShown(true);

        // hiding calendarview and daySpinner in datePicker
            dialog.getDatePicker().setCalendarViewShown(false);

            LinearLayout pickerParentLayout = (LinearLayout) dialog.getDatePicker().getChildAt(0);

            LinearLayout pickerSpinnersHolder = (LinearLayout) pickerParentLayout.getChildAt(0);

            pickerSpinnersHolder.getChildAt(0).setVisibility(View.GONE);


        dialog.setTitle("Pick a date");
        return dialog;
    }

    public void onDateSet(DatePicker view, int yy, int mm, int dd) {

        Calendar result = Calendar.getInstance();

        result.set(Calendar.YEAR, yy);
        result.set(Calendar.MONDAY, mm);
        result.set(Calendar.DAY_OF_MONTH, dd);

        if (currentWeek != -1) {
            updateDateWeek(result.getTimeInMillis());
        } else {
            updateDate(result.getTimeInMillis());
        }
    }
}

to show picker just call

DialogFragment newFragment = new SelectDateFragment();
newFragment.show(getActivity().getSupportFragmentManager(), "DatePicker");

Solution 3

This might work for you.. if you are doing for only English.. also can be changes according to the requirements.

Locale.setDefault(Locale.UK);

This will make date picker to appear in the form DD/MM/YYYY

Following code removes day spiner

LinearLayout pickerParentLayout =
(LinearLayout) mDatePicker.getChildAt(0);
LinearLayout pickerSpinnersHolder = (LinearLayout) pickerParentLayout.getChildAt(0);
NumberPicker picker = (NumberPicker) pickerSpinnersHolder.getChildAt(0);
picker.setVisibility(View.GONE);

Solution 4

This worked for me after trying out several different approaches.

 datePicker = (DatePicker) findViewById(R.id.date_picker);

 public void hideDay() {
    try {
        java.lang.reflect.Field[] f = datePicker.getClass().getDeclaredFields();
        for (java.lang.reflect.Field field : f) {
            if (field.getName().equals("mDayPicker") || field.getName().equals("mDaySpinner")) {
                field.setAccessible(true);
                Object dmPicker = new Object();
                dmPicker = field.get(datePicker);
                ((View) dmPicker).setVisibility(View.GONE);
            }
        }
    }
    catch (SecurityException e) {
        TLog.d("ERROR", e.getMessage());
    }
    catch (IllegalArgumentException e) {
        TLog.d("ERROR", e.getMessage());
    }
    catch (IllegalAccessException e) {
        TLog.d("ERROR", e.getMessage());
    }
}

Maybe this code sample helps : github.com/bendemboski/DateSlider/tree/develop/src/com/…

Be very careful using this method. You are effectively tying your code to specific implementation of the DatePickerDialog. If in the next minor version Google changes its implementation (e.g. renames the variable mDatePicker), your code will break. Moreover, if it works on stock google android, it doesn't mean that it will work on other devices, because different manufacturers often change things about in their implementation. I found it the hard way when using a similar technique.

[Usman Kurd]

agreed with you will optimize it further

[Heitara]

I would suggest pickerSpinnersHolder.findViewById(R.id.day).setVisibility(Vi‌​ew.GONE); based on mDaySpinner = (NumberPicker) findViewById(R.id.day); from android source code, because when your locate is US, this code hides the month spinner.

[Omama]

Agreed with Aleks G. He is absolutely right, this customization wont work for OS 5.0 or greater!!!
