When I implement this. I catch this event multiple time. Would you please provide solution.

 
private EditText  mDateOfBirth;
mDateOfBirth = (EditText) findViewById(R.id.sign_up_date_of_birth);
 mDateOfBirth.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {


           if (event.getAction() == MotionEvent.ACTION_UP) {

                Calendar now = Calendar.getInstance();
                DatePickerDialog dpd = DatePickerDialog.newInstance(
                        NewSignUpActivity.this,
                        now.get(Calendar.YEAR),
                        now.get(Calendar.MONTH),
                        now.get(Calendar.DAY_OF_MONTH)
                );
                dpd.show(getFragmentManager(), "Datepickerdialog");
                dpd.setMaxDate(now);

            }

            return false;
        }
    });
