无法在react本机中使用堆栈导航器

Question

App.js文件：

import 'react-native-gesture-handler';
        import * as React from 'react';
        import { NavigationContainer } from '@react-navigation/native';
        import { createStackNavigator } from '@react-navigation/stack';
        import Navigator from './routes/homeStack';
        import { StyleSheet, Text, View, Button } from 'react-native';

        export default function App(){
          return(

               <Navigator />

          );
        }


        const styles= StyleSheet.create({
          container:{
            fontSize: 24,
          }
        });

EditApollo.js文件：

import React,{Component} from 'react';
import {  Platform, StyleSheet, StatusBar, View, Text, TouchableOpacity, FlatList, 
TouchableHighlight} from 'react-native';
import Icon from 'react-native-vector-icons/FontAwesome';
import { NavigationContainer } from '@react-navigation/native';
import { createStackNavigator } from '@react-navigation/stack';
import firebase from 'firebase';
 if (!firebase.apps.length) {
   firebase.initializeApp({});}
class EditApollo extends Component {
 constructor(props){
  super(props);
    this.state={
    users1:[]
   }
  }
 componentDidMount= () =>{
  firebase.database().ref('users1').once('value').then(snapshot => {
     var items = [];
   snapshot.forEach((child) => {
     items.push({
        email: child.val().email,
        password: child.val().password,
       // price: child.val().price,
     });
  });
  this.setState({ users1: items});
  console.log(this.state.users1)
   });
  }
  render() {
  return(
    <View style={styles.container}>
   <FlatList style={{width:'100%'}} data={this.state.users1} showsVerticalScrollIndicator={false}
   renderItem={elem => (<View style={{elevation:8, marginBottom:13, borderRadius:15, 
  backgroundColor:'#575FCF', padding:20}}>
   <Text style={{fontSize:18, fontWeight:'bold', color:'#fff'}}>{elem.item.email}</Text>
  <Text style={{fontSize:18, fontWeight:'bold', lineHeight:25, color:'#fff'}}>{elem.item.password}  
  </Text>
  <View>
   <TouchableHighlight onPress={() => this.props.navigation.navigate('Edit1')}>
       <View>
             <Icon size={30} color="white" name="edit" />
       </View>
   </TouchableHighlight>        
   <TouchableHighlight>
      <View>
            <Icon size={30} color="white" name="close" />
      </View>
    </TouchableHighlight>        
  </View>
 </View>)}
  />
 </View>
 )
 }
 }
 export default EditApollo;

用于导航我的文件是homeStack.js

import { createStackNavigator } from 'react-navigation-stack';
import { createAppContainer } from 'react-navigation';
import { createStackNavigator } from 'react-navigation-stack';
import { createAppContainer } from 'react-navigation';
import Login from '../src/pages/Login';
import EditApollo from '../src/pages/EditApollo';
 import Edit1 from '../src/pages/Edit1';

 const screens={
  Login:{
    screen: Login,
    navigationOptions:{
    title: 'Login Page',
    headerStyle:{ backgroundColor:'#333' }
    } 
 },
 EditApollo:{
  screen: EditApollo,
  navigationOptions:{
    title: 'Edit Apollo Records',
    headerStyle:{ backgroundColor:'#333' }
   }
 },
 Edit1:{
    screen: Edit1,
   navigationOptions:{
    title: 'Edit Records',
    headerStyle:{ backgroundColor:'#333' }
   }
 },
 }

const HomeStack = createStackNavigator(screens, {
defaultNavigationOptions:{
    headerTintColor: '#eee',    
    headerStyle:{ height:50 }
 }
  });
export default createAppContainer(HomeStack);

Edit.js文件是

import React,{Component} from 'react';
import {  Platform, StyleSheet, StatusBar, View, Text } from 'react-native';
class Edit1 extends Component <{}>{
render(){
    return (
            <View style={styles.container}>
                <Text>hii</Text>
            </View>
        );
        }
    }
 const styles = StyleSheet.create({
 container: {
 flex:1,
 justifyContent: 'center',
  alignItems: 'center',
  backgroundColor: '#fff',
   },
 });
 export default Edit1;

package.json文件：

  {
   "name": "newapp",
   "version": "0.0.1",
   "private": true,
   "scripts": {
  "android": "react-native run-android",

 ]
 }
 }

我想导航到Edit1页面，但在onPress中显示类型错误:未定义不是一个对象(计算'__this2.props.navigation.navigate')，我应该怎么做才能解决这个错误？为什么这个错误会出现在this.props.navigation.navigate中，有什么特别的原因吗？

Answer 1

在updateApollo中加载EditApollo时，需要将导航属性传递给EditApollo

在您的UpdateApollo.js中：

更改：

<EditApollo />

至

<EditApollo navigation={navigation} />

这将修复您的错误。

按下后，导航至Edit screen：

希望这能有所帮助！
