推荐开源项目：react-native-tab - 简单高效的React Native标签页组件

import React from 'react';
import { View, Text } from 'react-native';
import { Scene, Tabs, Router } from 'react-native-router-flux';
 
const Home = () => <View><Text>Home</Text></View>;
const Settings = () => <View><Text>Settings</Text></View>;
 
const Primary = () => (
  <Tabs
    tabBarStyle={{ backgroundColor: '#ddd' }}
    tabBarPosition="bottom"
    lazy={true}
    pressOpacity={0.8}
    animated={true}
  >
    <Scene
      key="home"
      component={Home}
      title="Home"
      icon={() => <Icon name="home" />}
    />
    <Scene
      key="settings"
      component={Settings}
      title="Settings"
      icon={() => <Icon name="settings" />}
    />
  </Tabs>
);
 
export default () => (
  <Router sceneStyle={{ paddingTop: 64 }}>
    <Scene key="root">
      <Scene key="primary" component={Primary} />
    </Scene>
  </Router>
);

这个代码实例展示了如何在React Native应用中使用react-native-router-flux库创建一个带有底部标签栏的应用。Tabs组件被用来定义标签页，每个标签页由一个Scene组件表示，并且可以自定义图标和标题。这个例子简洁明了，并且教会了如何组织代码以便于后续的维护和扩展。
