javascript - 屏幕之间的 react native 导航

Question

我是react-native的初学者，我要在我的应用程序中实现react堆栈导航。我试图让我的 App.js 将我的 Home.js 渲染为默认屏幕。我希望使用 app.js 作为主屏幕并添加另一个登录屏幕，但我做不到。我无法弄清楚出了什么问题，我只得到开发服务器返回的响应错误代码: 500 。这是 App.js 的代码。

import React from 'react';
import { StyleSheet, Text, View, Button, KeyboardAvoidingView } from 'react-native';
import {createStackNavigator, createAppContainer} from 'react-navigation'

import Home from './Screens/Home';

const AppNavigator = createStackNavigator({
  Home: {screen: Home},
});

export default class App extends React.Component {

  render() {
    return (
      <AppNavigator />
    );
  }
}

这是我的 Home.js 文件。

import React from 'react';
import { StyleSheet, Text, View, Button, KeyboardAvoidingView } from 'react-native';
import {StackNavigator, createStackNavigator, createAppContainer} from 'react-navigation'


export default class Home extends React.Component {
  static navigationOptions = {
    title: 'Home',
  }

  render() {
    const { navigate } = this.props.navigation;
    return (
      <View>
        <Text>This is the Home HomeScreen</Text>
      </View>
    );
  }
}

您忘记创建应用程序容器，请查看此链接 https://reactnavigation.org/docs/en/hello-react-navigation.html

import React from 'react';
import { StyleSheet, Text, View, Button, KeyboardAvoidingView } from 'react-native';
import {createStackNavigator, createAppContainer} from 'react-navigation'

import Home from './Screens/Home';

const AppNavigator = createStackNavigator({
  Home: {screen: Home},
});

const AppContainer = createAppContainer(AppNavigator);

export default class App extends React.Component {

  render() {
    return (
      <AppContainer />
    );
  }
}
