Question

我在代码存在的反应原生代码中使用了以下代码：

header.js文件代码==

import React from 'react';
import { Text, View } from 'react-native';
const Header = () => {
    const { textStyle, viewStyle } = styles;
    return (
        <View style={viewStyle}>
            <Text style={textStyle}>Photography</Text>
        </View>
    );
};
const styles = {
    viewStyle: {
        backgroudColor: '#F8F8F8',
        justifyContent: 'center',
        alignItems: 'center',
        height: 60,
        paddingTop: 14
    },
    textStyle: {
        fontSize: 20
    }
};
export default Header;

app.js文件代码==

import React from 'react'; 
import { AppRegistry, Text } from 'react-native'; 
const App = () => (     <Text>Some Text</Text> );
AppRegistry.registerComponent('albums', () => App);

通常，您将拥有仅包含以下内容的index.js文件：

import { AppRegistry } from 'react-native';
import App from './App';

AppRegistry.registerComponent('albums', () => App);

...然后在App.js

import React, { Component } from 'react';
...
import Header from './header';

export default class App extends Component<{}> {
...
render() {
   return(
     <View style={styles.container}>
       <Header />
     </View>
   )
}
}
const styles = StyleSheet.create({
  container: {
     flex: 1,
     justifyContent: 'center',
     alignItems: 'center',
 },
...
}

react-native中的元素类型无效
