我正在使用来自react-native的新React-navigation。我的导航如下:
StackNavigator:
完整代码:
const MainNavigation = StackNavigator({
Home: {
screen: HomeNavigation,
},
Notification: {
screen: NotificationNavigation,
}
});
const HomeNavigation = TabNavigator({
AllPost: {
screen: All,
},
ArticlePost: {
screen: Article,
},
BusinessPost: {
screen: Job,
},
});
HomeNavigation.navigationOptions = {
title: 'Home',
header: {
right: <SearchNotification/>
},
};
class SearchNotification extends React.Component {
goToNotification = () => {
this.props.navigate('Notification');
};
render() {
return (
<View style={styles.container}>
<TouchableOpacity>
<Icon name="md-search" style={styles.Icon}/>
</TouchableOpacity>
<TouchableOpacity style={styles.notificationWrapper} onPress={this.goToNotification}>
<Icon name="md-notifications" style={styles.Icon}/>
<Text style={styles.number}>3</Text>
</TouchableOpacity>
</View>
)
}
}
const NotificationNavigation = TabNavigator({
Comment: {
screen: NotificationComment,
},
Follow: {
screen: NotificationFollow,
}
});
HomeNavigation有一个标题,标题有一个SearchNotification的正确组件。 SearchNotification有一个图标,我想按下NotificatoinNavigation。
但是,如果我以这种方式更改HomeNavigation的标题,则标题中不会显示SearchNotification。
HomeNavigation.navigationOptions = {
title: 'Home',
header: {
tintColor: 'white',
style: {
backgroundColor: '#2ec76e',
},
right: ({navigate}) => <SearchNotification navigate={navigate}/>
},
};
如何从标题中的按钮导航到不同的屏幕?

所以问题是(我认为),在navigationOptions
内而不是使用navigations
我必须使用navigate
,并将其作为道具传递给孩子(即<强> SearchNotification 强>)。
所以最终的代码如下:
HomeNavigation.navigationOptions = {
title: 'Home',
header: ({navigate}) => ({
right: (
<SearchNotification navigate={navigate}/>
),
}),
};
在 SearchNotification 组件中:
export default class SearchNotification extends React.Component {
goToNotification = () => {
this.props.navigate('Notification');
};
render() {
return (
<View style={styles.container}>
<TouchableOpacity>
<Icon name="md-search" style={styles.Icon}/>
</TouchableOpacity>
<TouchableOpacity style={styles.notificationWrapper}
onPress={() => this.props.navigate('Notification')}>
<Icon name="md-notifications" style={styles.Icon}/>
<Text style={styles.number}>3</Text>
</TouchableOpacity>
</View>
)
}
}

对我有用的代码:
import Header from '../Containers/Header'
.........................................
navigationOptions: ({ navigation }) => ({
title: 'Find User',
headerRight: <Header navigation={navigation} />,
headerStyle: styles.header
})
转到其他屏幕:
this.props.navigation.navigate('UserDetail', {});
