我试过这段代码。这对我来说可以。请尝试一次

private int pYear = 1970;
private int pMonth = 1;
private int pDay = 1;
static final int DATE_DIALOG_ID = 0;

然后在onCreate：

    edt_birth.setKeyListener(null);
    edt_birth.setOnTouchListener(new OnTouchListener() {
        @SuppressWarnings("deprecation")
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            showDialog(DATE_DIALOG_ID);
            return false;
        }
    });


@Override
protected Dialog onCreateDialog(int id) {
    switch (id) {
    case DATE_DIALOG_ID:
        return new DatePickerDialog(this, pDateSetListener, pYear, pMonth,
                pDay);
    }
    return null;
}

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

    public void onDateSet(DatePicker view, int year, int monthOfYear,
            int dayOfMonth) {
        pYear = year;
        pMonth = monthOfYear;
        pDay = dayOfMonth;
        updateDisplay();
    }
};

private void updateDisplay() {
    int temp = pMonth + 1;
    edt_birth.setText(pDay + "/" + temp + "/" + pYear);
    }

这将更新您的编辑文字。
