如何在react-native中定位制表符导航器

npm install @react-navigation/native

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

const Tab = createBottomTabNavigator();

const TabNavigator = () => {
  return (
    <NavigationContainer>
      <Tab.Navigator>
        <Tab.Screen name="Screen1" component={Screen1} />
        <Tab.Screen name="Screen2" component={Screen2} />
        <Tab.Screen name="Screen3" component={Screen3} />
      </Tab.Navigator>
    </NavigationContainer>
  );
};

const Screen1 = () => {
  return (
    <View>
      <Text>Screen 1</Text>
    </View>
  );
};

const Screen2 = () => {
  return (
    <View>
      <Text>Screen 2</Text>
    </View>
  );
};

const Screen3 = () => {
  return (
    <View>
      <Text>Screen 3</Text>
    </View>
  );
};

export default TabNavigator;

import React from 'react';
import TabNavigator from './TabNavigator';

const App = () => {
  return <TabNavigator />;
};

export default App;
