我正在使用来自react-native的新React-navigation。我的导航如下:
堆栈导航器:
- 选项卡导航器//主页导航
- 选项卡导航器//通知导航
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,并且标题具有SearchNotification的正确组件。搜索通知有一个图标,按下我想转到通知导航。
但是,如果我以这种方式更改主页导航的标题,则标题中不会显示搜索通知。
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
里面,我不得不使用navigate
而不是使用navigations
,并将其作为道具传递给孩子(即搜索通知(。
所以最终代码看起来像这样:
HomeNavigation.navigationOptions = {
title: 'Home',
header: ({navigate}) => ({
right: (
<SearchNotification navigate={navigate}/>
),
}),
};
在搜索通知组件中:
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
})
并移动到其他屏幕:
this.props.navigation.navigate('UserDetail', {});
