大家好，我是编程和 React Native 的新手，我正在尝试在两个不同的屏幕之间导航，两个屏幕都在同一页面上，我尝试使用 React Navigation 但它不起作用，并且我不确定我是否以正确的方式使用它。

Answer 1

我建议使用 React Router 创建单页应用程序，它们具有适用于移动设备的路由器类型

以下是 React Native 的文档： React Router Native Quick Start

这是一个书面教程： React Native Router Tutorial

还有一个 youtube 教程： React Router Native Tutorial

Answer 2

import * as React from 'react'; import { Button, View, Text } from 'react-native';import { NavigationContainer } from '@react-navigation/native'; import { createStackNavigator } from '@react-navigation/stack'; const Stack = createStackNavigator();

function HomeScreen({ navigation }) { return (
<View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
  <Text>Home Screen</Text>
  <Button
    title="Go to Details"
    onPress={() => navigation.navigate('Details')}
  />
</View>);}


 function DetailsScreen({ navigation }) {return (
<View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
  <Text>Details Screen</Text>
  <Button
    title="Go to Details... again"
    onPress={() => navigation.navigate('Home')}
  />
</View>);}

function App() { return (
<NavigationContainer>
  <Stack.Navigator >
    <Stack.Screen name="Home" component={HomeScreen} />
    <Stack.Screen name="Details" component={DetailsScreen} />
  </Stack.Navigator>
</NavigationContainer>);} export default App;
