DatePicker 和 TimePicker 改变值

Question

我有 DatePicker。如果我使用键盘更改值（年），则该值保持不变。只有当我点击按钮“+”或“-”时，值才会改变.... 这是我的听众：

   datePicker.init(year, month, day, new DatePicker.OnDateChangedListener() {
        @Override
        public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
            mDate.set(Calendar.YEAR, year);
            mDate.set(Calendar.MONTH, monthOfYear);
            mDate.set(Calendar.DAY_OF_MONTH, dayOfMonth);
            getArguments().putSerializable(EXTRA_DATE, mDate);
        }
    });

和 TimePicker 的类似问题（更改任何内容）

      timePicker.setOnTimeChangedListener(new TimePicker.OnTimeChangedListener() {
        @Override
        public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
            mTime.set(Calendar.HOUR_OF_DAY, hourOfDay);
            mTime.set(Calendar.MINUTE, minute);
            getArguments().putSerializable(EXTRA_TIME, mTime);
        }

    })

和内部片段

    public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if(resultCode != Activity.RESULT_OK) return;
    if(requestCode == REQUEST_DATE){
        Calendar date = (Calendar)data.getSerializableExtra(DateFragment.EXTRA_DATE);
        mObject.setDate(date);
        SimpleDateFormat dateFormat = new SimpleDateFormat("EE, dd.MM.yy", Locale.US);
        mDateButton.setText(dateFormat.format(mObject.getDate().getTime()));
    }
    if(requestCode == REQUEST_TIME){
        Calendar date = (Calendar)data.getSerializableExtra(TimeFragment.EXTRA_TIME);
        mObject.setDate(date);
        SimpleDateFormat dateFormat = new SimpleDateFormat("hh:mm, a", Locale.US);
        mTimeButton.setText(dateFormat.format(mObject.getDate().getTime()));
    }
}

Answer 1

DatePicker 仅在从 EditText 年失去焦点后才响应日期更改。

因此您可以使用 datePicker.clearChildFocus(getCurrentFocus()) 清除它的焦点，然后获取它的日期值。
