Question

我在反应原生中遇到TabNavigator和StackNavigator的问题。我想按下按钮时重置导航。我的选项卡导航中有我的堆栈导航。问题是我只能重置一个导航...

计划：

-tabNavigator
   -listing.js
   -stackNavigator
      -types.js
      -picture.js
      -ad.js

所以当我在ad.js中时，我点击它时有一个按钮，我的stackNavigation重置为list.js上的type.js和tabNavigator 所以我想最终回到Linsting.js。

我的导航：navigation.js

export const resetAction = NavigationActions.reset({
  index: 0,
  actions: [
    NavigationActions.navigate({ routeName: 'Types'}),
  ],
  key: null
})
export const listingAction = NavigationActions.navigate({
    routeName: 'Listing',
  })


const Stack = StackNavigator(
  {
    Types: {screen: SelectTypesScreen},
    Picture: {screen: SelectPictureScreen},
    Ad: {screen: CreateAd}
  })

const Tab = TabNavigator(
  {
    Listing: {screen: ListingScreen},
    Preference: {screen: PreferencesScreen},
    Add: {screen : Stack}
  },
  {

  }
)

export default class App extends Component {
    render() {
      return (
          <Tab />
      );
    }
  }

标签导航linsting.js

export default class Listing extends Component {
    render() {
        return (
            <View>
                <Text> Listing </Text>
            </View>
        );
    }
}

堆栈导航ad.js

export default class CreateAd extends Component {
    render() {
        return (
            <View>
                <Text style={{marginTop: '80%', marginLeft: '40%'}}> Ad </Text>
                <Button title="Ok" onPress={() => {console.log("displayer 1"), this.props.navigation.dispatch(resetAction), console.log("displayer 2"), this.props.navigation.dispatch(listingAction)}} />
            </View>
        );
    }
}

更好地更改Navigations嵌套结构。最好采用与文档完全相同的方式。根导航器可以是stacknavigator，您可以将tabnavigator添加为屏幕

const MainScreenNavigator = TabNavigator({
  Recent: { screen: RecentChatsScreen },
  All: { screen: AllContactsScreen },
});

const SimpleApp = StackNavigator({
  Home: { screen: MainScreenNavigator },
  Chat: { screen: ChatScreen },
});

参考文档 https://reactnavigation.org/docs/intro/nesting
