import {

StyleSheet,

Text,

View

} from 'react-native'

import Swiper from 'react-native-swiper'

const styles =StyleSheet.create( {

wrapper: {

slide1: {

flex: 1,

justifyContent: 'center',

alignItems: 'center',

backgroundColor: '#9bebe5'

slide2: {

flex: 1,

justifyContent: 'center',

alignItems: 'center',

}

});

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,

<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}>

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')}/>
