我正在使用新的
React-navigation从反应本地。我有导航如下:
StackNavigator: > TabNavigator // HomeNavigation 全部代码: 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,标题具有SearchNotification的正确组件。 SearchNotification有一个图标,按照我想去“通知导航”。 但是,如果以这种方式更改HomeNavigation的标题,则SearchNotification不会显示在标题中。 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(我想),在navigationOptions中,而不是使用导航,我不得不使用导航,并将其作为道具传递给孩子(即SearchNotification)。
所以最终的代码如下所示: 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> ) } } (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
