Question

我试图通过按图像组件在不同的屏幕之间导航。每个不同的图像导致一个不同的屏幕。

我首先尝试通过单击“ meo.sudoeste.png”到“ meo_sw”进行导航。但是，每当我按下图像时，都不会发生任何事情。这是我的SearchScreen.js：

import React from 'react';
import {View, Text, StyleSheet, TouchableOpacity, TextInput, ScrollView, Image} from 'react-native';
import * as firebase from 'firebase';
import Icon from 'react-native-vector-icons/Ionicons';
import { StackNavigator } from 'react-navigation';

export default class HomeScreen extends React.Component { 
constructor(props) {
  super(props);
  this.state = {    }
    }

render() {      
    return (
    <View style={styles.screen}>
      <View style={styles.container}>
        <View>
          <Icon name={"ios-search"} style={styles.icon}/>
        </View>
        <TextInput style={styles.inputBox}
                  underlineColorAndroid='rgba(0,0,0,0)' 
                  placeholder="Procura aqui"
                  placeholderTextColor = "black"
                  selectionColor="black"
                  keyboardType="default"/>
      </View>
        <ScrollView style={styles.teste}> 
          <Text style={styles.festivais}>Recomendados</Text>
            <ScrollView horizontal={true} showsHorizontalScrollIndicator={false} style={styles.festivais_lista}>
              <TouchableOpacity onPress={() => this.props.navigation.navigate('meo_sw')}>
                <Image source={require('../assets/meo_sudoeste.png')} style={styles.image}/>
              </TouchableOpacity>
              <TouchableOpacity onPress={() => navigation.navigate('vodaf_coura')}>
                <Image source={require('../assets/vodafone_coura.png')} style={styles.image} />
              </TouchableOpacity>
              <TouchableOpacity onPress={() => navigation.navigate('superR_superB')}>
                <Image source={require('../assets/superbock_superrock.png')} style={styles.image}/>
              </TouchableOpacity>
              <TouchableOpacity onPress={() => navigation.navigate('nos')}>
                <Image source={require('../assets/nos_primavera.png')} style={styles.image}/>
              </TouchableOpacity>
              <TouchableOpacity onPress={() => navigation.navigate('rock_in_rio')}>
                <Image source={require('../assets/rock_in_rio.png')} style={styles.image}/>
              </TouchableOpacity>
              <TouchableOpacity onPress={() => navigation.navigate('edp_cool_jazz')}>
                <Image source={require('../assets/edp_cooljazz.png')} style={styles.image}/>
              </TouchableOpacity>
            </ScrollView>                    
      </ScrollView>
    </View>
  );       
}
  }


const styles = StyleSheet.create({
  // I took this off because it is irrelevant.
});

能帮我吗？

这是我的App.js：

  const AuthStack= createStackNavigator({

Answer 1

为了导航到另一个屏幕，该屏幕必须包含在AppContainer中。

如果您想使用meo_sw导航到this.props.navigation.navigate('meo_sw')屏幕，请创建一个名为meo_sw的新屏幕并将其放在AppContainer内。

希望这对您有所帮助。放心怀疑。
