反应本机向量问题

Question

我花了很多时间来解决这个问题，但找不到解决方案。皮斯 需要有关如何从反应矢量图标获取图标的帮助。在我的代码下面和 包.json 文件。我只想在导航栏中添加一个菜单图标...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：需要字符串(对于内置组件(或 类/函数(用于复合组件(，但得到：未定义。你可能忘了 从定义组件的文件中导出组件，否则您可能混淆了 违约

并命名导入。

Answer 1

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

在这里，您可以获得集合的完整列表。
