我试图通过将Image路径作为道具发送到应该渲染的组件来显示一个简单的.jpg图像。以下面的方式。
App.js
import React, { Component } from 'react';
import { View, Text, Image } from 'react-native';
import Header from './components/Header';
import ImageSlider from './components/ImageSlider';
import ImageShow from './components/ImageShow';
class App extends Component {
render () {
return (
<View style={{flex:1}}>
<Header headerText = "HONEST REVIEWS" />
<ImageSlider />
<ImageShow imagePath = "./abc.jpg"/>
<ImageShow imagePath = "./abc.png" />
</View>
);
}
}
export default App;
ImageShow.js
import React from 'react';
import { View, Image, Dimensions } from 'react-native';
const widthOfScreen = Dimensions.get('window').width;
const ImageShow = (imageProps) => {
return (
<View>
<Image style = { {width: 50, height: 50} } source = { {uri: imageProps.imagePath} } />
</View>
);
};
const styles = {
ImageStyle : {
height: 30,
width: widthOfScreen
}
}
export default ImageShow;
ImageSlider.js
import React from 'react';
import Carousel from 'react-native-banner-carousel';
import { StyleSheet, Image, View, Dimensions } from 'react-native';
const BannerWidth = Dimensions.get('window').width;
const BannerHeight = 250;
const images = [
require('./abc.jpg'),
require('./abc.jpg'),
require('./abc.jpg')
];
export default class ImageSlider extends React.Component {
renderPage(image, index) {
return (
<View key={index}>
<Image style={styles.imagesInSlider} source = { image } />
</View>
);
}
render() {
return (
<View style={styles.container}>
<Carousel
autoplay
autoplayTimeout={2000}
loop
index={0}
pageSize={BannerWidth}
>
{images.map((image, index) => this.renderPage(image, index))}
</Carousel>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#fff',
justifyContent: 'flex-start',
alignItems: 'center'
},
imagesInSlider: {
width: BannerWidth,
height: 250,
resizeMode: 'stretch',
}
});
我的文件夹结构是:
ProjectName
------src
--------components
-----------ImageShow.js
-----------ImageSlider.js
-----------Header.js
-----------abc.jpg
--------App.js
理想情况下,当我通过本地存储的图像路径时,应该显示图像,但是我没有显示任何图像,而是一条警告消息,内容为: “失败的道具类型:提供给'ForwardRef(image)'的道具'来源'无效”
答案 0 :(得分:0)
此代码对我有效获取图片
import image1 from '../assets/images/abc.png'
import image2 from '../assets/images/abc.png'
const images = [
{
name: image1
},
{
name: image2
}]
const RenderPage = ({ image }) => {
return (
<Image resizeMode="contain" style={{ width: 50, height: 100, marginBottom: 5 }} source={image} />
)
}
class myclass extends Component {
render() {
return (
<View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
{images.map((image, index) =>
<RenderPage key={index} image={image.name} />
)}
</View>
)
}
}
