我想在React Native中使用情感。我能够让它在styled-components上工作,但不能在emotion上工作。我也在使用styled-system来设置我的UI系统。
我正在设置一个样式系统,如下所示:
import React from 'react';
import * as N from 'react-native';
// import styled from 'styled-components';
import styled from '@emotion/native';
import {
compose,
space,
color,
layout,
typography,
flexbox,
border,
background,
position,
grid,
shadow,
buttonStyle,
colorStyle,
textStyle
} from 'styled-system'
const themed = key => props => props.theme[key]
// const types = variant
const View = styled(N.View)(
compose(
space,
color,
layout,
typography,
flexbox,
border,
background,
position,
grid,
shadow,
buttonStyle,
colorStyle,
textStyle,
themed('SSN')
)
)
const Text = props => <View as={N.Text} {...props} />
const Image = props => <View as={N.Image} {...props} />
const TextInput = props => <View as={N.TextInput} {...props} />
const ScrollView = props => <View as={N.ScrollView} {...props} />
const Picker = props => <View as={N.Picker} {...props} />
const Slider = props => <View as={N.Slider} {...props} />
const Switch = props => <View as={N.Switch} {...props} />
const FlatList = props => <View as={N.FlatList} {...props} />
const SectionList = props => <View as={N.SectionList} {...props} />
const ActivityIndicator = props => <View as={N.ActivityIndicator} {...props} />
const Alert = props => <View as={N.Alert} {...props} />
const Modal = props => <View as={N.Modal} {...props} />
const StatusBar = props => <View as={N.StatusBar} {...props} />
const Button = ({ children, color, fontFamily, fontSize, fontWeight, lineHeight, letterSpacing, textAlign, fontStyle, ...props }) => (
<View as={N.TouchableOpacity} {...props}>
<View as={N.Text} color={color} fontFamily={fontFamily} fontSize={fontSize} fontWeight={fontWeight} lineHeight={lineHeight} letterSpacing={letterSpacing} textAlign={textAlign} fontStyle={fontStyle} >{children}</View>
</View>
)
export {
View, Text, Image, TextInput, ScrollView, Picker, Slider, Switch, FlatList, SectionList, ActivityIndicator, Alert, Modal, StatusBar, Button
}然后,我尝试呈现一个基本组件,如下所示:
import React from 'react';
import { Text, View, Button } from '../styled-system';
export const TestStyledSystem = () => {
return (
<View justifyContent="center" alignItems="center">
<Text>Hello! </Text>
</View>
);
};我在组件的第7行得到了一个Invariant violation: Text strings must be rendered within a <Text> component。如果我用一个组件来尝试,也会发生同样的事情。
此外,同样的代码可以在styled-system上运行,而不是在@emotion/native上运行,所以我正在尝试找出其中的区别。

你会试着在页面上添加一些情感吗?存在一个包@emotion/native。
类型: npm install @native/core@native/native to install。
并将const声明为样式表,例如:const emotionLogo = 'https://cdn.rawgit.com/emotion-js/emotion/master/emotion.png'
然后使用:
<Image
source={{
uri: emotionLogo,
height: 150,
width: 150
}}
