我在react-native中构建应用并使用ex-navigation实现导航。我想使用TabNav快速访问最常用的功能,并将DrawerNav用于应该可用但不经常使用的功能。
我搜索并尝试了自己,但我不能将抽屉和标签导航在一起。前 - navigation example app有两个但不在一起。它从抽屉导航开始,当我点击Tab导航示例时,抽屉图标消失了。
有没有人有一些提示/提示如何完成这项工作?

您是否尝试将导航标签屏幕放在导航中?

import React, { Component } from 'react';
import { createRouter } from '@expo/ex-navigation';
import NavigationDrawer from './NavigationDrawer';
import NavigationTab from './NavigationTab';
export const Router = createRouter(() => ({
navigationDrawer : () => NavigationDrawer,
navigationTab : () => NavigationTab
}));

import React, { Component } from 'react';
import {
StackNavigation,
DrawerNavigation,
DrawerNavigationItem,
} from '@expo/ex-navigation';
import { Router } from './Router';
export default class NavigationDrawer extends Component{
render(){
return(
<DrawerNavigation
drawerPosition="left"
drawerWidth={300}
initialItem="navigationTab" >
<DrawerNavigationItem
id="home"
selectedStyle={{backgroundColor: '#E8E8E8',}}
renderTitle={isSelected => renderTitle('Home', isSelected)}
renderIcon={isSelected => renderIcon('home', isSelected)}
>
<StackNavigation
id="navigationTab"
initialRoute={Router.getRoute('navigationTab')}
defaultRouteConfig={{
navigationBar: {
backgroundColor: '#0084FF',
tintColor: '#fff',
title: 'NavigationTab',
},
}}
/>
</DrawerNavigationItem>
</DrawerNavigation >
);
}
}
<强> NavigationTab.js 强>
import React, { Component } from 'react';
import {
StackNavigation,
TabNavigation,
TabNavigationItem,
} from '@expo/ex-navigation';
import { Router } from './Router';
export default class NavigationTab extends Component {
render() {
return (
<TabNavigation
initialTab="first"
initialItem="first"
<TabNavigationItem
id="first"
title="First"
>
{/*content*/}
</TabNavigationItem>
<TabNavigationItem
id="second"
title="Second"
>
{/*content*/}
</TabNavigationItem>
<TabNavigationItem
id="third"
title="Third"
>
{/*content*/}
</TabNavigationItem>
</TabNavigation>
)
}
}
使用此方法,可以同时使用抽屉和标签导航,但是当您从抽屉菜单中选择项目(使用堆栈导航)时,将替换带有标签的屏幕。
如果您希望从抽屉菜单中的每个屏幕中都有标签,您需要在每个屏幕中添加标签(我认为这应该是不必要的)。
