我正在使用React Navigation v5中的抽屉式导航。在我的根文件中,我创建了抽屉导航器。该导航器内部的某些屏幕具有嵌套的堆栈导航器。第一项是仪表板,第二项是“关系”。
问题在于,当我处理关系时,没有返回到第一个屏幕(仪表板)的后退按钮。可以将其添加到我的关系屏幕吗?
根代码:
<NavigationContainer>
<DrawerNavigator.Navigator
drawerContent={(props) => (
<SidebarComponent {...props} user={this.props.device.user} />
)}
drawerPosition="right"
drawerStyle={{width: '90%', padding: 0, backgroundColor: 'red'}}>
{this.props.authenticated && this.props.device.api_key ? (
<>
<DrawerNavigator.Screen
name="Home"
options={{
headerShown: false,
icon: 'tachometer-alt',
category: 'dashboard',
}}
component={DashboardStack}
/>
<DrawerNavigator.Screen
name="Relations"
options={{
icon: 'address-book',
category: 'dashboard',
}}
component={RelationsStack}
/>
</>
) : (
<>
<DrawerNavigator.Screen
name="login"
options={{headerShown: false, gestureEnabled: false}}
component={LoginStack}
/>
</>
)}
</DrawerNavigator.Navigator>
</NavigationContainer>
关系堆栈代码:
import 'react-native-gesture-handler';
import React from 'react';
import {createStackNavigator} from '@react-navigation/stack';
import RelationsListScreen from '../RelationsListScreen';
import {colors} from '../../../assets/styles/variables';
const Stack = createStackNavigator();
function RelationsStack() {
return (
<Stack.Navigator>
<Stack.Screen
options={{
headerShown: true,
headerTintColor: '#FFF',
headerStyle: {
backgroundColor: colors.primary,
shadowColor: 'transparent',
},
}}
name="Relations"
component={RelationsListScreen}
/>
</Stack.Navigator>
);
}
export default RelationsStack;

您可以创建一个堆栈导航器,该堆栈导航器是您的抽屉式导航器的屏幕(在验证用户身份时),其屏幕为Home
和Relations
。在下面的示例中,我将此导航器称为AuthenticatedNavigator
:
const AuthenticatedStack = createStackNavigator();
// ...
const AuthenticatedNavigator = () => {
return (
<AuthenticatedStack.Navigator screenOptions={{headerShown: false}}>
<AuthenticatedStack.Screen
name="Home"
options={{
icon: 'tachometer-alt',
category: 'dashboard',
}}
component={DashboardStack}
/>
<AuthenticatedStack.Screen
name="Relations"
options={{
icon: 'address-book',
category: 'dashboard',
}}
component={RelationsStack}
/>
</AuthenticatedStack.Navigator>
);
};
function CustomDrawerContent(props) {
return (
<DrawerContentScrollView {...props}>
<DrawerItem
label="Home"
onPress={() => props.navigation.navigate('Home')}
/>
<DrawerItem
label="Relations"
onPress={() => props.navigation.navigate('Relations')}
/>
</DrawerContentScrollView>
);
}
function App() {
const authenticated = true;
return (
<NavigationContainer>
<DrawerNavigator.Navigator
drawerPosition="right"
drawerStyle={{width: '90%', padding: 0, backgroundColor: 'red'}}
drawerContent={(props) => <CustomDrawerContent {...props} />}>
{authenticated ? (
<DrawerNavigator.Screen
name="authenticated"
component={AuthenticatedNavigator}
/>
) : (
<DrawerNavigator.Screen
name="login"
options={{headerShown: false, gestureEnabled: false}}
component={LoginStack}
/>
)}
</DrawerNavigator.Navigator>
</NavigationContainer>
);
}
我还使用了自定义抽屉内容组件,因此在使用创建另一个堆栈导航器的方法后,抽屉中的链接仍然可以正常工作。您可以在this answer的文档中阅读有关提供自定义抽屉组件的更多信息。
为了简化示例,我省略了一些代码,并将authenticated
设置为硬编码值。另外,请确保从DrawerItem
导入DrawerContentScrollView
,@react-navigation/drawer
。
