react项目有react-router作为路由，react-native无法使用react-router。那么在rn的项目中我们使用react-navigation 来解决页面的跳转。
官网地址： https://reactnavigation.org
这个依赖的包较多，需要 react-native-gesture-handler react-native-reanimated react-native-screens react-native-safe-area-context @react-native-community/masked-view。

package.json 中的 dependencies如下：

"@react-native-community/masked-view": "^0.1.10",
"@react-navigation/native": "^5.2.3",
"@react-navigation/stack": "^5.2.18",
"react": "16.11.0",
"react-native": "0.62.2",
"react-native-gesture-handler": "^1.6.1",
"react-native-safe-area-context": "^0.7.3",
"react-native-screens": "^2.7.0"

写个demo试试

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

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 Home" onPress={() => navigation.navigate('Home')} />
    </View>
  );
}

const Stack = createStackNavigator();

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

export default App;

运行效果：

官方还提供了基于TAB的跳转方式

"@react-navigation/bottom-tabs": "^5.3.3",

TabDemo

import {createBottomTabNavigator} from '@react-navigation/bottom-tabs';
import {Button, Text, View} from 'react-native';
import * as React from 'react';
import {NavigationContainer} from '@react-navigation/native';

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 Home" onPress={() => navigation.navigate('Home')} />
    </View>
  );
}

const Tab = createBottomTabNavigator();

function MyTabs() {
  return (
    <NavigationContainer>
      <Tab.Navigator>
        <Tab.Screen name="Home" component={HomeScreen} />
        <Tab.Screen name="Details" component={DetailsScreen} />
      </Tab.Navigator>
    </NavigationContainer>
  );
}

export default MyTabs;
