React-Native之swiper(轮播组件)
使用说明:
1. 先安装React-native-swiper
npm i react-native-swiper –save
2. 导入Swiper
import Swiper from ‘react-native-swiper’;
代码:
import React, {Component} from 'react'import {
StyleSheet,
Text,
View
} from 'react-native'
import Swiper from 'react-native-swiper'
const styles =StyleSheet.create( {
wrapper: {
}, //整体样式
slide1: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#9bebe5'
},
slide2: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#e3b1e5'
},
slide3: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#90d985'
},
text: {
color: '#ff6fa3',
fontSize: 30,
fontWeight: 'bold'
}
});
export default class HomePage extends Component{
render(){
return(
<Swiper style={styles.wrapper}
showsButtons={true} //显示控制按钮
loop={true} //如果设置为false,那么滑动到最后一张时,再次滑动将不会滑到第一张图片。
autoplay={true} //自动轮播
autoplayTimeout={3} //每隔3秒切换
dot={<View style={{ //未选中的圆点样式
backgroundColor: 'rgba(0,0,0,0.2)',
width: 18,
height: 18,
borderRadius: 4,
marginLeft: 10,
marginRight: 9,
marginTop: 9,
marginBottom: 9,
}}/>}
activeDot={<View style={{ //选中的圆点样式
backgroundColor: '#83ffcf',
width: 18,
height: 18,
borderRadius: 4,
marginLeft: 10,
marginRight: 9,
marginTop: 9,
marginBottom: 9,
}}/>}
>
<View style={styles.slide1}>
<Text style={styles.text}>青衣</Text>
</View>
<View style={styles.slide2}>
<Text style={styles.text}>冷秋</Text>
</View>
<View style={styles.slide3}>
<Text style={styles.text}>听雨</Text>
</View>
</Swiper>
)
}
};
效果:
带有图片的轮播:
import React, { Component } from 'react'import {
View,
Image,
Dimensions,
StyleSheet
} from 'react-native'
import Swiper from 'react-native-swiper';
const { width, height } = Dimensions.get('window');//获取手机的宽和高
const styles =StyleSheet.create( {
wrapper: {
},
container: {
flex: 1,//必写
},
image: {
width,//等于width:width
height,
}
});
export default class HomePage extends Component {
render () {
return (
<View style={styles.container}>
<Swiper style={styles.wrapper}
showsButtons={true} //为false时不显示控制按钮
paginationStyle={{ //小圆点位置
bottom: 70
}}
loop={false} //如果设置为false,那么滑动到最后一张时,再次滑动将不会滑到第一张图片。
autoplay={true} //自动轮播
autoplayTimeout={2} //每隔2秒切换
>
<Image style={styles.image} source={require('../images/1.jpg')}/>
<Image style={styles.image} source={require('../images/2.jpg')}/>
<Image style={styles.image} source={require('../images/4.jpg')}/>
</Swiper>
</View>
)
}
}
