我花了很多时间来解决这个问题,但是找不到解决方案。豆豆 在如何从反应矢量图标获取图标方面需要您的帮助。在我的代码下面 package.json文件。我只想向导航栏添加菜单图标...感谢您的帮助
import React from 'react';
import {View, Text, StyleSheet, Image, TouchableOpacity} from 'react-native';
// import {FiMenu} from 'react-icons/fi';
//import MenuIcon from '@material-ui/icons/Menu';
import Icon from 'react-native-vector-icons/';
const MenuNav = ({navigation}) => {
const showDrawer = () => {
navigation.openDrawer();
};
return (
<View style={styles.menucontainer}>
<TouchableOpacity style={styles.img} onPress={showDrawer}>
<Image source={require('../imgs/menu.png')} />
<Icon
name="check"
color="rgba(0, 0, 0, 0.38)"
size={25}
type="entypo"
/>
</TouchableOpacity>
<Text style={styles.text}>Menu</Text>
</View>
);
};

错误:元素类型无效:预期为字符串(对于内置组件)或 类/函数(用于复合组件),但得到:未定义。您可能忘记了 从定义的文件中导出您的组件,否则您可能混淆了 默认
和命名的导入。
答案 0 :(得分:0)
您以错误的方式导入Icon
。
在react-native-vector-icons
中,您应该这样做:
import Icon from 'react-native-vector-icons/SimpleLineIcons'
// and replace SimpleLineIcons with the set of icons you want to use
