在React Native中创建滑动选项卡按钮可以通过使用第三方库来实现。以下是一种常见的方法:
npm install react-native-tab-view
import React, { useState } from 'react';
import { View, StyleSheet, Dimensions } from 'react-native';
import { TabView, SceneMap, TabBar } from 'react-native-tab-view';
const FirstRoute = () => (
<View style={[styles.scene, { backgroundColor: '#ff4081' }]} />
);
const SecondRoute = () => (
<View style={[styles.scene, { backgroundColor: '#673ab7' }]} />
);
const ThirdRoute = () => (
<View style={[styles.scene, { backgroundColor: '#4caf50' }]} />
);
const FourthRoute = () => (
<View style={[styles.scene, { backgroundColor: '#2196f3' }]} />
);
const App = () => {
const [index, setIndex] = useState(0);
const [routes] = useState([
{ key: 'first', title: 'First' },
{ key: 'second', title: 'Second' },
{ key: 'third', title: 'Third' },
{ key: 'fourth', title: 'Fourth' },
]);
const renderScene = SceneMap({
first: FirstRoute,
second: SecondRoute,
third: ThirdRoute,
fourth: FourthRoute,
});
const renderTabBar = props => (
<TabBar
{...props}
indicatorStyle={styles.indicator}
style={styles.tabBar}
/>
);
return (
<TabView
navigationState={{ index, routes }}
renderScene={renderScene}
onIndexChange={setIndex}
renderTabBar={renderTabBar}
/>
);
};
const styles = StyleSheet.create({
scene: {
flex: 1,
},
tabBar: {
backgroundColor: '#fff',
},
indicator: {
backgroundColor: '#ff4081',
},
});
export default App;
npx react-native run-android
以上代码将创建一个带有滑动选项卡按钮的React Native应用程序。你可以根据需要自定义选项卡的样式和内容。
