如何使用createStackNavigator将createBottomTabNavigator添加到同一屏幕

Question

在我的主屏幕上（我使用App.js作为我的家），我有createStackNavigator和createAppContainer来使用React-Navigation映射所有屏幕。它工作正常，我可以从任何屏幕明确导航到这些屏幕中的任何一个。现在，我想使用“createBottomTabNavigator”在主屏幕上添加一个底部选项卡导航栏。

这是我的代码的简化版本：

import { createStackNavigator, createAppContainer, createBottomTabNavigator  } from 'react-navigation';
import Screen1 from './Screens/Screen1';
import Screen2 from './Screens/Screen2';
import Screen3 from './Screens/Screen3';

class HomeScreen extends React.Component {
   render() {
      return (
         <View><Text>Welcome</Text></View>
      );
   }
 }

 const AppNavigator = createStackNavigator({
   Home: { screen: HomeScreen },
   Screen1: { screen: Screen1 },
   Screen2: { screen: Screen2 },
   Screen3: { screen: Screen3 },
 });

 export default createAppContainer(AppNavigator);

我想在底部添加一个导航栏，如下所示：

const TabNavigator = createBottomTabNavigator({
   Home: { screen: HomeScreen },
   Screen3: { screen: Screen3 },
});

export default createAppContainer(TabNavigator);

它不允许在同一页面内有两个“导出默认值”。如何在保持“createStackNavigator”映射我的所有屏幕的同时添加“createBottomTabNavigator”？

像这样的东西。

import { createStackNavigator, createAppContainer, createBottomTabNavigator } from 'react-navigation';
import Screen1 from './Screens/Screen1';
import Screen2 from './Screens/Screen2';
import Screen3 from './Screens/Screen3';
import Screen4 from './Screens/Screen4';

const Home = createStackNavigator({
  Screen1, Screen2
});

const List = createStackNavigator({
  Screen3, Screen4
});

const TabNav = createBottomTabNavigator({
  Home, List
});

export default createAppContainer(TabNav);

在这里你的家可以是Screen1和Screen2可以是Screen1的项目和Screen3 and Screen4相同

您可以使用以下代码：

import { createStackNavigator, createAppContainer, createBottomTabNavigator } from 'react-navigation';
import Screen1 from './Screens/Screen1';
import Screen2 from './Screens/Screen2';
import Screen3 from './Screens/Screen3';

class HomeScreen extends React.Component {
  render() {
    return (
       <View><Text>Welcome</Text></View>
    );
 } 
}

const AppNavigator = createStackNavigator({
  Home: { screen: TabNavigator },
  Screen1: { screen: Screen1 },
  Screen2: { screen: Screen2 },
  Screen3: { screen: Screen3 },
});

const TabNavigator = createBottomTabNavigator({
  Home: { screen: HomeScreen },
  Screen3: { screen: Screen3 },
});

export default createAppContainer(AppNavigator);
