我似乎无法在新版本的 React Navigation 中将标头配置为 null。我可以使用 headerTransparent 选项将其设置为透明,但这看起来标题仍然存在,因为屏幕仍然需要一个名称。
这就是标题为 transparent 的样子。这基本上是我想看到的,但标题仍然被强加在那里。
我不想要带有导航的标题,但这看起来像是默认行为。我尝试查看文档以查看是否有删除标题的道具,但遇到了 404 选项页面:https : //reactnavigation.org/docs/en/navigation-options.html
我是 React Native 的新手,所以可能有一些误解。但是文档对此不清楚,我找不到直接解决此问题的计算器溢出问题。
这是我的 App.js
import { NavigationContainer } from '@react-navigation/native';
import { createStackNavigator } from '@react-navigation/stack';
import BottomTabNavigator from './navigation/BottomTabNavigator';
import useLinking from './navigation/useLinking';
const Stack = createStackNavigator();
........
<NavigationContainer ref={containerRef} initialState={initialNavigationState}>
<Stack.Navigator>
<Stack.Screen name="root" component={BottomTabNavigator} options={{headerTransparent: true}}/>
</Stack.Navigator>
</NavigationContainer>

这是我的BottomTabNavigator.js,和expo提供的模板代码非常相似。
import * as React from 'react';
import { createBottomTabNavigator } from '@react-navigation/bottom-tabs';
import TabBarIcon from '../components/TabBarIcon';
import HomeScreen from '../screens/Home';
import SearchScreen from '../screens/Search';
const BottomTab = createBottomTabNavigator();
const INITIAL_ROUTE_NAME = 'Home';
export default function BottomTabNavigator({ navigation, route }) {
navigation.setOptions({ headerTitle: getHeaderTitle(route) });
return (
<BottomTab.Navigator initialRouteName={INITIAL_ROUTE_NAME}>
<BottomTab.Screen
name="Home"
component={HomeScreen}
options={{
title: 'Home',
tabBarIcon: ({ focused }) => <TabBarIcon focused={focused} name="md-home" />
}}
/>
<BottomTab.Screen
name="Search"
component={SearchScreen}
options={{
title: 'Search',
tabBarIcon: ({ focused }) => <TabBarIcon focused={focused} name="md-search" />,
}}
/>
</BottomTab.Navigator>
);
}
function getHeaderTitle(route) {
const routeName = route.state?.routes[route.state.index]?.name ?? INITIAL_ROUTE_NAME;
switch (routeName) {
case 'Home':
return 'How to get started';
case 'Appointments':
return 'Your appointments';
case 'Search':
return 'Search for services';
case 'Account':
return 'Account'
}
}

在您的场景中,您有两种选择。您可以禁用所有屏幕的标题,也可以仅禁用所选屏幕的标题。
要为您的应用程序禁用标题,请像这样编辑您的 app.js
应用程序.js
import { NavigationContainer } from '@react-navigation/native';
import { createStackNavigator } from '@react-navigation/stack';
import BottomTabNavigator from './navigation/BottomTabNavigator';
import useLinking from './navigation/useLinking';
const Stack = createStackNavigator();
........
<NavigationContainer ref={containerRef} initialState={initialNavigationState}>
<Stack.Navigator screenOptions={{headerShown: false,}}>
<Stack.Screen name="root" component={BottomTabNavigator}/>
</Stack.Navigator>
</NavigationContainer>

您需要将screenOptions传递到Stack.Navigator并使headerShown:false
假设您只想在特定屏幕上禁用标题,那么此示例将帮助您
<Stack.Navigator ...>
...
<Stack.Screen
name="Landing"
component={LandingScreen}
options={{
headerShown: false, // change this to `false`
}}
/>
...
</Stack.Navigator>
