我在RN中导航有问题,所以我认为你可以帮助我.我找不到任何方式从我的“设置”选项卡导航到我的“SignedOut”,this is my repo,代码并不复杂,所有你需要看的是“导航”和“屏幕”文件夹.事情是我的“设置”文件在一个文件“MainTabNavigator”和SignedOut在“RootNavigation”,当我尝试这样的事情:
this.props.navigation.navigate("SignedOut"); 什么都没发生,这是我的功能: onSignOut() .then(() => { console.log('Logout!'); this.props.navigation.navigate("SignedOut"); }) .catch(e => { console.log(e); }) 我打印出这个日志,所以应该成功调用这个导航方法.你有什么想法吗?我的意思是,我认为这就是我错过的原因吗? 这就是我的MainTabNavigator的样子: import React from 'react'; import { Platform } from 'react-native'; import { Ionicons } from '@expo/vector-icons'; import { TabNavigator,TabBarBottom,DrawerNavigator } from 'react-navigation'; import Colors from '../constants/Colors'; import HomeScreen from '../screens/HomeScreen'; import ListScreen from '../screens/ListScreen'; import SettingsScreen from '../screens/SettingsScreen'; import WordDetails from '../screens/WordDetails'; import DrawerMenu from './drawerDesign/Drawer'; export default DrawerNavigator( { Home: { screen: HomeScreen,},List: { screen: ListScreen,Settings: { screen: SettingsScreen,WordDetails: { screen: WordDetails,{ contentComponent: DrawerMenu,drawerWidth: 200,drawerPosition: "right",contentOptions: { activeTintColor: '#e91e63',itemsContainerStyle: { marginVertical: 0,opacity: 0.6 },iconContainerStyle: { opacity: 0.6 },style: { flex: 1,paddingTop: 35,} } ); SingedOutNavigator: import React from 'react'; import { Platform,StatusBar,Easing,Animated } from 'react-native'; import { Ionicons } from '@expo/vector-icons'; import { StackNavigator } from 'react-navigation'; import Colors from '../constants/Colors'; import SignIn from '../screens/SignInScreen'; import Register from '../screens/RegisterScreen'; const headerStyle = { marginTop: Platform.OS === "android" ? StatusBar.currentHeight : 0,backgroundColor: '#2b303b',}; export default StackNavigator( { SignIn: { screen: SignIn,navigationOptions: { title: "Prijavi se",headerStyle,headerTitleStyle: { color: '#f5f5f5' },Register: { screen: Register,} },{ headerMode: "none",transitionConfig: () => ({ transitionSpec: { duration: 1000,easing: Easing.step0,timing: Animated.timing,screenInterpolator: sceneProps => { const { layout,position,scene } = sceneProps const { index } = scene const height = layout.initHeight const translateY = position.interpolate({ inputRange: [index - 1,index,index + 1],outputRange: [height,0],}) const opacity = position.interpolate({ inputRange: [index - 1,index - 0.99,index],outputRange: [0,1,1],}) return { opacity,transform: [{ translateY }] } },}),} ); 从这个“设置”屏幕我想从“SignedOutNavigator”继续这个“SignIn”.. 解决方法
根据我的理解,您正在构建一个应用程序,其中某些屏幕仅在用户被查看时才可用.
因此,当用户注销时,您应该清除导航的历史记录,以便用户无法使用后部硬件按钮导航回来. 你应该做的事情如下: this.props.navigation.dispatch(NavigationActions.reset({ index: 0,key: null,actions: [ NavigationActions.navigate({ routeName: "SignedOut" }) ] })); (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! |
