如何在 React Native 的 Textinput 字段中打开和设置日期 - datepicker

Question

This is what I am trying. On focus of TextInput datepicker does get open but after selecting date it is not getting populated in TextInput field. Where I am making mistake?

<TouchableOpacity>
  <TextInput style={styles.textinputstyle} onFocus={()=>{setOpen(true)}} />
</TouchableOpacity>
<DatePicker modal mode="date" dateFormat="MM-DD-YYYY" open={open} date={date} onConfirm={date=> { setOpen(false) setDate(date) }} onCancel={() => { setOpen(false) }} />

Answer 1

set editable = false in TextInput

 const [isDatePickerVisible, setDatePickerVisibility] = useState(false);
  const [birthDate, setBirthDate] = useState('');

  const showDatePicker = () => {
    setDatePickerVisibility(true);
  };

  const hideDatePicker = () => {
    setDatePickerVisibility(false);
  };

  const handleConfirm = date => {
    setBirthDate(date);
    hideDatePicker();
  };

 <TouchableOpacity onPress={showDatePicker}>
          <TextInput
            numberOfLines={1}
            editable={false}
            placeholder="Choose Your Date of Birth"
            value={moment(birthDate).format('DD MMMM, YYYY')}
            style={{
              fontSize: 16,
              paddingVertical: 10,
              color: 'black',
            }}
          />
          <DateTimePickerModal
            isVisible={isDatePickerVisible}
            maximumDate={new Date(moment().add(-1, 'days'))}
            mode="date"
            onChange={date => setBirthDate(date)}
            value={handleConfirm}
            onConfirm={handleConfirm}
            onCancel={hideDatePicker}
          />
        </TouchableOpacity>
