react-native - react 导航，返回嵌套导航

Question

Stack Navigator :
 - Login
 - Register
 - Activation
 - Tab Navigator
    + Home
    + Histories
    + Cart
    + Profile
 - Outlet
 - Product

我在返回导航时遇到问题，当我在产品屏幕中时，我可以使用 navigation.navigate('Cart'); 转到“购物车屏幕”，但是在“购物车屏幕”和 goBack() 中，我的屏幕转到“主屏幕”。
如何管理 goBack() 从堆栈屏幕到标签屏幕？

在 react-navigation(在 5 之前)中，我确实实现了您所说的使用自定义导航组件将上导航作为 Prop 向下传递，如下所示:

// this component's navigation is replaced by upper navigation, you can send another prop if you need both navigations.
const MyComponent0 = createStackNavigator(
  {
    Child1: {
      screen: Child1,
      navigationOptions: ({navigation}) => {
        return {
          headerRight: (
            // you can use BackButton of library with import it, I wrote my own, that time i didn't know there is a ready importable back button.
            <TouchableOpacity
              style={{paddingLeft: 10}}
              onPress={() => navigation.toggleDrawer()}>
              <Icon ios="ios-menu" android="md-menu" style={{color: '#fff'}} />
            </TouchableOpacity>
          ),
          headerTitle: <Text style={styles.whiteText}>Child1 title</Text>,
          headerLeft: (
            <HeaderBackButton
              style={{color: '#FFF'}}
              onPress={() => navigation.goBack(null)}
            />
          ),
        };
      },
    },
    Child2,
    ...
  },
  {
    defaultNavigationOptions: {
      headerTitleStyle: {
        color: '#fff',
        fontSize: 13,
        ...Platform.select({
          android: {
            fontFamily: ...,
          },
          ios: {
            fontFamily: ...,
          },
        }),
      },
      headerStyle: {
        backgroundColor: 'rgba(0,0,0,1)',
      },
      headerTintColor: 'white',
    },
  },
);


class MyComponent1 extends Component {
  constructor() {
    super();
  }
  static router = MyComponent0.router;

  render() {
    return <MyComponent0 navigation={this.props.navigation} />; // you can send like navigation1 if you need downward navigation too.
  }
}

这段代码是旧方法，但它在 5 之前使用 react-navigation 工作。
我希望这可以帮助你。
