DatePickerDialog datePickerDialog = new DatePickerDialog(view.getContext(),
        new DatePickerDialog.OnDateSetListener() {

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

                txtDate.setText(dayOfMonth + "-" + (monthOfYear + 1) + "-" + year);

            }
        }, mYear, mMonth, mDay);
datePickerDialog.getDatePicker().setMaxDate(c.getTimeInMillis());
