React Native- 出現錯誤：重新渲染次數過多。 React 限制渲染次數以防止在顯示模態時出現無限循環

Question

我有一個服務詳細信息頁面，我想在單擊“添加到購物車”按鈕時打開一個模式，但是我收到太多重新呈現錯誤，我嘗試了很多不同的方法但似乎無法修復它。 請幫忙

這是 ServiceDetails function 我在單擊“添加到購物車”按鈕時將 cartmodalVisible 的 state 設置為 true，然后將該 state 作為道具傳遞給 CartModal

const ServiceDetailsScreen = ({navigation, route}) => {
  const [data, setData] = useState({});
  const [LabData, setLabData] = useState({});
  const [TestData, setTestData] = useState({});
  const [Service, setService] = useState({});
  const [cartmodalVisible, setcartmodalVisible] = useState(false);
  const [bookNowModal, setbookNowModal] = useState(false);
  const id = route.params.id;
  // console.log('id rececived', id);
  const getServiceDetails = async () => {
    try {
      console.log('id of service', route.params.id);
      const {data} = await axios.get(
        `${url}/Inventory/getServiceDetail/${id}`,
      );
      // console.log(' call sent');
      setData(data);

      setLabData(data.LabData);
      setTestData(data.TestData);
    } catch (error) {
      console.log(error);
      ToastAndroid.show('Something went wrong', ToastAndroid.SHORT);
    }
  };

  useEffect(() => {
    getServiceDetails();
  }, [id]);

  return (

            title="Book Now"
            buttonStyle={{
              backgroundColor: '#34C38F',
              borderColor: 'transparent',
              borderWidth: 0,

            }}></Button>
        </View>
      </View>
    </View>
  );
};

export default ServiceDetailsScreen;

這是我的模態

const Cartmodal = props => {
  const {cartmodalVisible} = props;
  const [visible, setVisible] = useState(cartmodalVisible);
  console.log('cartmodalVisible', cartmodalVisible);

    return (
      <Modal
        animationType="slide"
        transparent={true}
        visible={visible}
        onRequestClose={() => {
          setVisible(!visible);
        }}
        onDismiss={() => {
          setVisible(!visible);
        }}
      >
        <View style={modalstyles.centeredView}>
          <View style={modalstyles.modalView}>
            <View style={modalstyles.modalHeader}>
              <View style={modalstyles.modalHeaderContent}>
                <Text>Add to Cart</Text>
              </View>
              <TouchableOpacity onPress={setVisible(!visible)}>
                <Text style={modalstyles.modalHeaderCloseText}>X</Text>
              </TouchableOpacity>
            </View>
            <Text style={modalstyles.modalText}>Hello World!</Text>
            <Pressable style={[modalstyles.button, modalstyles.buttonClose]}>
              <Text style={modalstyles.textStyle}>Cancel</Text>
            </Pressable>
          </View>
        </View>
      </Modal>
    );
 
};

您的問題出在 CartModal 組件中

改變這個

<TouchableOpacity onPress={setVisible(!visible)}>
    <Text style={styles.modalHeaderCloseText}>X</Text>
</TouchableOpacity>

對此

<TouchableOpacity onPress={() => setVisible(!visible)}>
    <Text style={styles.modalHeaderCloseText}>X</Text>
</TouchableOpacity>

TouchableOpacity onPress 運行了多次。
