探索无线世界：React Native的Wi-Fi P2P库

import React, { useEffect, useState } from 'react';
import { StyleSheet, Text, View } from 'react-native';
import WiFiP2p from 'react-native-wifi-p2p';
 
export default function App() {
  const [wifiP2pState, setWifiP2pState] = useState('未初始化');
 
  useEffect(() => {
    WiFiP2p.initialize(
      () => setWifiP2pState('初始化成功'),
      (error) => setWifiP2pState(`初始化失败: ${error}`),
      WiFiP2p.CONNECTION_INFO_AVAILABLE,
    );
  }, []);
 
  return (
    <View style={styles.container}>
      <Text style={styles.text}>Wi-Fi P2P 状态: {wifiP2pState}</Text>
    </View>
  );
}
 
const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
  },
  text: {
    fontSize: 20,
    textAlign: 'center',
  },
});

这段代码展示了如何在React Native应用中初始化Wi-Fi Direct (P2P)库，并在应用的UI中显示初始化结果。代码使用了React Hooks (useEffect和useState)来管理副作用和组件状态，这是React Native的当前推荐做法。
