[英]Unable to load images in react-native
I got stuck with loading images in react-native. 我陷入了将图像加载到本机的状态。 I went through all the solutions given in the similar questions posted but the answers are not helpfull in my case. 我经历了类似问题中给出的所有解决方案,但答案对我而言没有帮助。 I tried importing the images like how we do in react like using import or require but both the options are not working. 我尝试导入图像,就像我们在使用import或require这样的反应中所做的一样,但是这两个选项均不起作用。
PFB code for your ref PFB代码供您参考
import React, { Component } from 'react';
import { Card, CardTitle, CardContent, CardAction, CardButton, CardImage } from 'react-native-material-cards';
import aboutImage from "https://images.pexels.com/photos/34950/pexels-photo.jpg";
import {
Button,
View,
Text,
ScrollView, StyleSheet
} from 'react-native'
class About extends Component {
handleScroll = e => {
}
render() {
return (
<ScrollView onScroll={this.handleScroll}>
<View style={styles.container}>
<Text style={styles.text}>Who we are</Text>
<Card style={{backgroundColor: "#fff", boxShadow: "2px 3px #3333"}}>
<CardImage
source={{uri:aboutImage }}
title="About US"
/>
<CardContent text="Testing" />
</Card>
</View>
</ScrollView>
)
}
}
const styles = StyleSheet.create({
container: {
alignItems: 'center',
margin: 20
},
text:{
color: "#06357a",
fontWeight: "bold",
fontSize: 30,
fontFamily: "FreeSans,Arimo,Droid Sans,Helvetica,Arial,sans-serif"
},
text1:{
color: "#06357a",
fontWeight: "bold",
fontFamily: "FreeSans,Arimo,Droid Sans,Helvetica,Arial,sans-serif"
}
});
export default About;
.babelrc .babelrc
{
"presets": ["module:metro-react-native-babel-preset"]
}
I tried downloading images to local and use require to import them but I get below error 我尝试将图像下载到本地并使用require导入它们,但出现以下错误
error: bundling failed: Error: Unable to resolve module
../../../../assets/AboutUS.jpg
fromD:\\react-native\\AppUsingRN\\components\\Layout\\components\\About.js
: The module../../../../assets/AboutUS.jpg
could not be found fromD:\\react-native\\AppUsingRN\\components\\Layout\\components\\About.js
. 错误:捆绑失败:错误:无法从D:\\react-native\\AppUsingRN\\components\\Layout\\components\\About.js
解析模块../../../../assets/AboutUS.jpg
:模块../../../../assets/AboutUS.jpg
无法从找到D:\\react-native\\AppUsingRN\\components\\Layout\\components\\About.js
。 Indeed, none of these files exist: 实际上,这些文件都不存在:
I imported it like 我像导入
<CardImage
source={{uri: require('../../../../assets/AboutUS.jpg')}}
title="About US"
/>
I am not able to figure out the issue. 我无法解决问题。
It should work with: 它应该与:
<CardImage
source={{ uri: "https://images.pexels.com/photos/34950/pexels-photo.jpg" }}
title="About US"
/>
if use require
如果require
使用
const imageByRequire = require('../../../../assets/AboutUS.jpg'); <CardImage source={imageByRequire} title={'About US'} />
if use uri
directly 如果直接使用uri
const imageByUri = "https://images.pexels.com/photos/34950/pexels-photo.jpg"; <CardImage source={imageByUri} title={'About US'} />
If "It's not working somehow", maybe downloading or download error(there would be nothing), perhaps you can plus defaultSource
. 如果“以某种方式无法正常工作”,可能是下载或下载错误(什么都没有),也许您可以加上defaultSource
。
const imageByUri = "https://images.pexels.com/photos/34950/pexels-photo.jpg"; const defaultImage = require('../../../../assets/AboutUS.jpg'); <CardImage defaultSource={defaultImage} source={imageByUri} title={'About US'} />
hope helpful :) 希望对您有所帮助:)
