如何将 createBottomTabNavigator 添加到与 createStackNavigator 相同的屏幕

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。它起作用了，我可以从任何屏幕明确导航到这些屏幕中的任何一个。现在我想用 "createBottomTabNavigator".

添加一个底部标签导航栏到主屏幕

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是这样的：

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

export default createAppContainer(TabNavigator);

不允许在同一页面中出现两个 "export default"。如何在保持 "createStackNavigator" 映射我所有屏幕的同时添加 "createBottomTabNavigator"？

Answer 1

您可以使用如下代码：

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);

像这样。

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);

这里你的主页可以是 Screen1 和 Screen2 可以是 Screen1 的一个项目，对于 Screen3 and Screen4
