react-native从入门到实战系列教程一Swiper组件的使用及bug修复

轮播图，在app中随处可见，这么重要的功能我们怎么可能不学习下在react-native中的实现方式。
依然是第三方组件react-native-swiper

官网地址

https://www.npmjs.com/package/react-native-swiper

组件使用的组件及事件参考官方即可。

实现效果

• 官网示例实现
  
• 业务需求实现
  

代码实现

import {View,Text,Image,StyleSheet,Dimensions,ScrollView,
} from 'react-native';
import {useEffect, useState} from 'react';
import Logo from '../../assets/images/logo.png';
import Ionicons from 'react-native-vector-icons/Ionicons';
import Swiper from 'react-native-swiper';function HomeScreen() {const windowWidth = Dimensions.get('window').width;return (<Viewstyle={{flex: 1,justifyContent: 'flex-start',alignItems: 'center',width: '100%',backgroundColor: '#F5FCFF',}}><View style={styles.box}><Swiper style={styles.swiper} height={200} horizontal={true} autoplay><Imagesource={{uri: 'https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1o9rRO.img?w=768&h=538&m=6&x=297&y=153&s=399&d=155',}}style={styles.img}/><Imagesource={{uri: 'https://img-s-msn-com.akamaized.net/tenant/amp/entityid/BB1r4EGh.img?w=640&h=427&m=6&x=160&y=169&s=82&d=82',}}style={styles.img}/><Imagesource={{uri: 'https://img-s-msn-com.akamaized.net/tenant/amp/entityid/BB1r4vmA.img?w=640&h=360&m=6&x=198&y=83&s=103&d=103',}}style={styles.img}/></Swiper></View></View>);
}
const styles = StyleSheet.create({img: {width: Dimensions.get('window').width,height: 200,resizeMode: 'cover',},box: {height: 200,backgroundColor: '#F5FCFF',},
});
export default HomeScreen;

bug修复

可能是截图软件的原因，没有捕捉到轮播在自动循环播放的时候，会出现闪烁的闪电现象。后来发现好多人遇到，我这里是使用模拟器，不知道真机效果是不是也这样。

• 修复方式
  removeClippedSubviews={false}在组件上加上这个配置即可修复闪烁现象

<SwiperremoveClippedSubviews={false}style={styles.swiper}height={200}horizontal={true}autoplay><Imagesource={{uri: 'https://img-s-msn-com.akamaized.net/tenant/amp/entityid/AA1o9rRO.img?w=768&h=538&m=6&x=297&y=153&s=399&d=155',}}style={styles.img}/><Imagesource={{uri: 'https://img-s-msn-com.akamaized.net/tenant/amp/entityid/BB1r4EGh.img?w=640&h=427&m=6&x=160&y=169&s=82&d=82',}}style={styles.img}/><Imagesource={{uri: 'https://img-s-msn-com.akamaized.net/tenant/amp/entityid/BB1r4vmA.img?w=640&h=360&m=6&x=198&y=83&s=103&d=103',}}style={styles.img}/></Swiper>
