Question

我正在创建过滤器页面屏幕。.在该屏幕上，我填写了要过滤数据的所有数据后，我将单击“保存”按钮，这会将我重定向到主页，其中新过滤的数据将在该主页上显示。我的主页已经显示了常规数据，但是如果我想查看过滤器数据，那么我将从过滤器屏幕中过滤该数据。
但是这里我有问题是我无法重定向到主页。我用于重定向的代码对于我的整个应用程序都是相同的，可以正常运行。我只在重定向到主页时遇到问题，控制台中没有显示错误，但会打印我在函数中编写的消息。而不是什么也没做。

import NavigationService from '../../components/NavigationService';
    onSaveClicked() {

        console.log('Filter is in progress');
        const { navigation } = this.props;
        navigation.navigate('home');
        const { userprofile } = this.props;
        const  { type } = userprofile;
        NavigationService.navigate('HomeStackScreen1', {type:type});


      }
  renderButton() {
    return (
      <Button
        style={{ alignItems: 'center' }}
        onPress={this.onSaveClicked.bind(this)}
      >
        Filter
      </Button>
    );
  }

navigationService.js

    import { NavigationActions,navigation } from 'react-navigation';

let _navigator;

function setTopLevelNavigator(navigatorRef) {
  _navigator = navigatorRef;
}

function navigate(routeName, params) {
  _navigator.dispatch(
    NavigationActions.navigate({
      routeName,
      params
    })
  );
}

function getParams(param){
  console.log("param: "+param);
  _navigator.dispatch(
    console.log("param: "+param),
    navigation.getParam(param)
  );
}


export default { setTopLevelNavigator, navigate, getParams };

导航堆栈：

    const HomeStack = createStackNavigator(
  {
    HomeStackScreen1: {
      screen: DrawerNavigation,
      navigationOptions: ({ navigation }) => ({
        title: 'Action',
        headerLeft: (
          <DrawerButton name="navicon" style={styles.Headercss} navigation={navigation} />
        ),
        headerRight: (
          <SearchButton style={styles.Headercss} navigation={navigation} />
        ),
        //headerStyle: { paddingRight: 5, paddingLeft: 5 },
        headerTitleStyle: { color: 'rgb(234, 94, 32)' }

      })
    },
    Project: {
      screen: ProjectTab,
      navigationOptions: () => ({
        title: '  Create New Project',
        headerTintColor: 'rgb(234, 94, 32)', 
      })
    },
    Notification: {
      screen: NotificationScreen
    },
    Filters: {
     screen: FilterScreen,
     navigationOptions: () => ({
      title: 'Filter',
      headerTintColor: 'rgb(234, 94, 32)', 
    })
    },
    UpdateProfile: {
      screen:UserProfileScreen,
      navigationOptions: () => ({
        title: 'Profile',
        headerTintColor: 'rgb(234, 94, 32)', 
      })
    },
    ViewActorProfile: {
      screen: ViewActorProfileScreen,
      navigationOptions: () => ({
        title: 'View Profile',
        headerTintColor: 'rgb(234, 94, 32)', 
      })
    },
    ViewProducer :{
      screen: ViewProducerProfile,
      navigationOptions: () => ({
        title: 'View Profile',
        headerTintColor: 'rgb(234, 94, 32)', 
      })
    },
    ProjectView: {
      screen: ViewProject,
      navigationOptions: () => ({
        title: 'View Project',
        headerTintColor: 'rgb(234, 94, 32)', 
      })
    },
    AppliedProjectScreen: {
      screen: AppliedProjectUsers,
      navigationOptions: () => ({
        title: 'Applied Users',
        headerTintColor: 'rgb(234, 94, 32)', 
      })
    },
    ChattingScreen: {
      screen: Chat,
      navigationOptions: {
        title: 'Chat'
      }
    },
    ViewActorProfileScreen: {
      screen: ViewActorProfileScreen,
      navigationOptions: () => ({
        title: 'View Profile',
        headerTintColor: 'rgb(234, 94, 32)',
      })
    }
  },
  {
    initialRouteName: 'HomeStackScreen1',
    headerMode: 'screen'
  }
);

Answer 1

您必须使用确切的家庭路线名称作为导航参数：

navigation.navigate('HomeStackScreen1');

如果需要，还可以在导航堆栈上将HomeStackScreen1重命名为Home。

navigation.navigate在本机反应中不起作用
