在我的标题组件中,有一个菜单图标。当我按图标时,它应该打开绘制活动。
我已经尝试添加
const { navigate } = this.props.navigation;
,但不幸的是,它没有解决问题。
我的标题组件:
import React, { Component } from 'react';
import { View, Text, Image, Button } from 'react-native';
import Icon from 'react-native-vector-icons/Ionicons';
import styles from '../assets/stylesheets/theme';
export default class Header extends Component {
render() {
return (
<View style={styles.header}>
<Icon onPress={() => navigate('DrawerToggle')} name="md-menu" style={styles.headerIcon} />
<Image source={require('../assets/images/f1today.png')} resizeMode="contain" style={styles.headerLogo} />
<View style={{ flex: 1 }} />
</View>
)
}
}
我的主屏幕,我导入标头组件:
import React, { Component } from 'react';
import { View, Text, Button } from 'react-native';
import Header from '../../components/header';
import styles from '../../assets/stylesheets/theme'
export default class HomeScreen extends Component {
render() {
return(
<View style={styles.applicationView}>
<Header />
<Text>Home Screen</Text>
</View>
);
}
}
按下标题内的图标
时出现此错误如何在标题组件内使用导航?预先感谢。
update
标题组件:
import React, { Component } from 'react';
import { View, Text, Image, Button } from 'react-native';
import Icon from 'react-native-vector-icons/Ionicons';
import styles from '../assets/stylesheets/theme';
export default class Header extends Component {
render() {
const { navigate } = this.props.navigation;
return (
<View style={styles.header}>
<Icon onPress={this.props.navigate('DrawerToggle')} name="md-menu" style={styles.headerIcon} />
<Image source={require('../assets/images/f1today.png')} resizeMode="contain" style={styles.headerLogo} />
<View style={{ flex: 1 }} />
</View>
)
}
}
主屏幕:
import React, { Component } from 'react';

return(
<View style={styles.applicationView}>
<Header navigation={this.props.navigation} />
<Text>Home Screen</Text>

);
}
}
更新后错误
您需要像这样的标题组件将导航对象传递给标头组件
<Header navigation={this.props.navigation} />
您的标题组件现在应该是这样的
export default class Header extends Component {
render() {
return (
<View style={styles.header}>
<Icon onPress={this.openDrawer.bind(this)} name="md-menu" style={styles.headerIcon} />
<Image source={require('../assets/images/f1today.png')} resizeMode="contain" style={styles.headerLogo} />
<View style={{ flex: 1 }} />
</View>
)
}
openDrawer() {
this.props.navigation.navigate('DrawerToggle');
}
}
