DatePickerDialog打开两次

Question

我想用这种格式在Edit-Text中显示我的日期：YYYY-MM-DD。但我有一些问题。首先，当我触摸日期的编辑文本时，键盘仍然打开。我想摆脱它。然后，Date-Picker-Dialog出现两次。如果我设置了一次，则会再次出现对话框选择器。当我第二次设置日期时，日期在编辑文本中设置。我使用Fragments。第一个Fragment附加在第一个Activity上，第二个Fragment附加到第二个Activity上。

    date.setOnTouchListener(new View.OnTouchListener() {

                @Override
                public boolean onTouch(View v, MotionEvent event) {
                    Date_Alert(v);
                    return true;
                }

                private void Date_Alert(View v)
                {

    getActivity().getWindow().setSoftInputMode(
        WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN
    );                
    DatePickerDialog datePickerDialog = new DatePickerDialog(this,
                new DatePickerDialog.OnDateSetListener() {

                    @Override
                    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                        //date_str = dayOfMonth + "-" + (monthOfYear + 1) + "-" + year;
                        mYear = year;
                        mMonth = monthOfYear;
                        mDay = dayOfMonth;
                        mMonthName = MONTHS[monthOfYear];
                        Log.d("before", "onDateSet: " + mYear + "" + mMonthName + "" + mDay);
                        start_date_str = mDay + " " + mMonthName + " " + mYear;

                    }
