如何更新日期选择器设置按钮上的edittext

Question

这是我的代码，它可以很好地更新编辑文本，但问题是编辑文本在我再次点击编辑文本之前不会立即更新

    EditText edtKeyword;
    String selectedDate;
int mYear,mMonth,mDay ;
    DateFormat fmtDateAndTime = DateFormat.getDateInstance();
Calendar myCalendar = Calendar.getInstance();
DatePickerDialog.OnDateSetListener d = new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year, int monthOfYear,
        int dayOfMonth) {
    myCalendar.set(Calendar.YEAR, year);
    myCalendar.set(Calendar.MONTH, monthOfYear);
    myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
        edtKeyword = (EditText) findViewById(R.id.edtKeyword);
        edtKeyword.setClickable(true);
        edtKeyword.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                new DatePickerDialog(MenuList.this, d, myCalendar
                    .get(Calendar.YEAR),                   
                     myCalendar.get(Calendar.MONTH),
         myCalendar.get(Calendar.DAY_OF_MONTH)).show();
                mYear = myCalendar.get(Calendar.YEAR);
                mMonth = myCalendar.get(Calendar.MONTH);
                mDay = myCalendar.get(Calendar.DAY_OF_MONTH);
                selectedDate= mMonth+"-"+mDay+"-"+mYear;
                edtKeyword.setText(selectedDate);               
        }
    });        
    edtKeyword.setText(fmtDateAndTime.format(myCalendar.getTime()));

我试过这个代码。它对我来说很好。请试用一次

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

然后在创建：

    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本。
