具有反应导航的本机应用程序。我有我的导航工作,但当我从CustomNavigationDrawer.js文件添加contentComponent时,我收到一个错误:
如果我直接在我的navigation.js中粘贴CustomNavigationDrawer.js中的代码,它可以工作,但我希望组件在不同的文件中,所以我可以保持它分开。
我尝试搜索问题,它给了我以下结果:
结构体:

Index.js:
export { CustomDrawerNavigator } from './CustomDrawerNavigator';
export { CustomHeader } from "./CustomHeader";
自定义抽屉Navigation.js:
import React from "react";
import { View, StyleSheet } from "react-native";
import { DrawerItems } from "react-navigation";
export const CustomDrawerNavigator = (props) => (
<View style={[styles.container]}>
<DrawerItems
activeBackgroundColor={"black"}
activeTintColor={"white"}
iconContainerStyle={styles.icons}
{...props}
/>
</View>
);
const styles = StyleSheet.create({
container: {
flex: 1
},
icons: {
width: 30
}
});
Navigation.js:
import CustomDrawerNavigator from "../component";
...
const MainNavigator = createDrawerNavigator(
{
Main: {
navigationOptions: {
drawerIcon: ({ tintColor }) => (
<Ionicons name="md-home" style={{ color: tintColor }} />
),
drawerLabel: "Main"
},
screen: MainScreen
},
Login: {
navigationOptions: {
drawerIcon: ({ tintColor }) => (
<Ionicons name="md-settings" style={{ color: tintColor }} />
),
drawerLabel: "Login"
},
screen: LoginScreen
},
Profile: {
navigationOptions: {
drawerIcon: ({ tintColor }) => (
<Ionicons name="ios-person" style={{ color: tintColor }} />
),
drawerLabel: "Profile"
},
screen: ProfileScreen
}
},
{
contentComponent: props => <CustomDrawerNavigator {...props} />
}
);
...
任何人都可以帮我从不同的文件中显示contentCompenent吗?
import CustomDrawerNavigator from "../component";
上面的行预计你的组件有一个default export
......但没有找到
通过以下方式获取指定的导出:
import { CustomDrawerNavigator } from "../component";
