需要React Native的帮助。在Google中搜索,但没有找到任何解决方案。 我有一个在android上工作的项目。下面的代码:无法在React本机中运行自定义组件
import React, { Component } from 'react';
import {
AppRegistry,
StyleSheet,
Text,
View
} from 'react-native';
export default class MyApp extends Component {
render() {
return (
<View style={styles.container}>
<Text style={styles.welcome}>
Welcome to React Native!
</Text>
<Text style={styles.instructions}>
To get started, edit index.android.js
</Text>
<Text style={styles.instructions}>
Double tap R on your keyboard to reload,{'\n'}
Shake or press menu button for dev menu
</Text>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#F5FCFF',
},
welcome: {
fontSize: 20,
textAlign: 'center',
margin: 10,
},
instructions: {
textAlign: 'center',
color: '#333333',
marginBottom: 5,
},
});
AppRegistry.registerComponent('MyApp',() => MyApp);
但是,当我尝试添加自己的组件,但是这样的:
import React, { Component } from 'react';
import {
AppRegistry,
StyleSheet,
Text,
View
} from 'react-native';
import MainPage from "./app/components/MainPage/MainPage";
export default class MyApp extends Component {
render() {
return (
<View style={styles.container}>
<Text style={styles.welcome}>
Welcome to React Native!
</Text>
<Text style={styles.instructions}>
To get started, edit index.android.js
</Text>
<Text style={styles.instructions}>
Double tap R on your keyboard to reload,{'\n'}
Shake or press menu button for dev menu
</Text>
<MainPage/>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
justifyContent: 'center',
alignItems: 'center',
backgroundColor: '#F5FCFF',
},
welcome: {
fontSize: 20,
textAlign: 'center',
margin: 10,
},
instructions: {
textAlign: 'center',
color: '#333333',
marginBottom: 5,
},
});
AppRegistry.registerComponent('MyApp',() => MyApp);
有人可以帮忙吗? 组件MainPage代码:
import React, {Component} from 'react';
import {AppRegistry, StyleSheet, View, Text} from 'react-native';
export default class MainPage extends Component {
render() {
return (
<View>
<Text style={styles.welcome}>
Welcome to React Native!
</Text>
</View>
);
}
}
MainPage.propTypes = {}
MainPage.defaultProps = {}
const styles = StyleSheet.create({
welcome: {
fontSize: 20,
textAlign: 'center',
margin: 10,
}
});
AppRegistry.registerComponent('MainPage',() => MainPage);
你的问题似乎是你的模块导入文件的路径。确保它是正确的。 –
这是对的。我检查了它。我不明白为什么会发生,因为路径是正确的。 –
