        });

        final Calendar now = Calendar.getInstance();
        mYear = now.get(Calendar.YEAR);

@Override
    protected Dialog onCreateDialog(int id) {
        switch (id) {
            case DATE_DIALOG_ID:
                return new DatePickerDialog(this,
                            mDateSetListener,

    @Override
    protected void onPrepareDialog(int id, Dialog dialog) {
        switch (id) {

            case DATE_DIALOG_ID:
                ((DatePickerDialog) dialog).updateDate(mYear, mMonth, mDay);

                    .append(mDay).append("-")
                    .append(mMonth + 1).append("-")
                    .append(mYear).append(" "));

    private DatePickerDialog.OnDateSetListener mDateSetListener =
            new DatePickerDialog.OnDateSetListener() {

    @Override
    public void onDateSet(DatePicker view, int year,int monthOfYear, int dayOfMonth) {
                    // TODO Auto-generated method stub

            mYear = year;
                    mMonth = monthOfYear;

                    updateDisplay();

    //should add code here?             
                }
            };

We can not set any attribute which limits DatePicker to select a date which is not past, but we can do it programmatically, by:

if(dateObj1.before(dateObj2) || dateObj1.equals(dateObj2)){
//the program runs normally
}
else{

                new AlertDialog.Builder(PM_Edit.this)

                .setTitle("Wrong Data Input!")

                .setMessage("The end Date must be Before the start Date, please insert new Date values")

                .setNeutralButton("Ok",

                new DialogInterface.OnClickListener() {

                public void onClick(DialogInterface dialog,

                int which) {

                }

                }).show();
            }
