【问题描述】：
我是新来的反应并试图自己学习它，我在将用户从嵌套的 stck 导航器屏幕导航回根屏幕时遇到问题。
这是我的一些课程：-
index.android.js :-
import React, { Component } from 'react';
import {
AppRegistry,
StyleSheet,
Text,
StatusBar,
View
} from 'react-native';
import {LoginStack} from './login/loginregisterrouter';
import {StackNavigator } from 'react-navigation';
class reactNavigationSample extends Component {
render(){
return (
<LoginStack/>
);
}
}
AppRegistry.registerComponent('MssReactDemo', () => reactNavigationSample);
登录注册路由器：-
import React from 'react';
import {StackNavigator } from 'react-navigation';
import LoginScreen from './LoginScreen';
import RegisterScreen from './RegisterScreen';
import NavigationContainer from './navigationContainer';
export const LoginStack = StackNavigator({
LoginScreen: {
screen: LoginScreen,
navigationOptions: {
title: 'LoginScreen',
}
},
RegisterScreen: {
screen: RegisterScreen,
navigationOptions: ({ navigation }) => ({
title: 'RegisterScreen',
}),
},NavigationContainer: {
screen: NavigationContainer,
navigationOptions: ({ navigation }) => ({
title: 'NavigationContainer', header: null,
}),
},
});
Navigationcontainer.js :-
import React, { Component } from 'react';
import {
AppRegistry,
StyleSheet,
Text,
StatusBar,
View
} from 'react-native';
import {EasyRNRoute,} from '../parent';
import {StackNavigator } from 'react-navigation';
export default class NavigationContainer extends Component {
render(){
return (
<EasyRNRoute/>
);
}
}
parent.js :-
import React, { Component } from 'react';
import {
StyleSheet,
Text,
StatusBar,
View
} from 'react-native';
import App from './app';
import DrawerMenu from './Drawer/drawer-toolbar-android';
import BookmarkView from './Pages/bookmark';
import ClientView from './Pages/client';
import InfoView from './Pages/info';
import SettingsView from './Pages/setting';
import { DrawerNavigator, StackNavigator } from 'react-navigation';
export const stackNavigator = StackNavigator({
Info: { screen: InfoView },
Settings: {screen: SettingsView },
Bookmark: {screen: BookmarkView },
Connections: {screen: ClientView},
}, {
headerMode: 'none'
});
export const EasyRNRoute = DrawerNavigator({
Home: {
screen: App,
},
Stack: {
screen: stackNavigator
}
}, {
contentComponent: DrawerMenu,
contentOptions: {
activeTintColor: '#e91e63',
style: {
flex: 1,
paddingTop: 15,
}
}
});
抽屉工具栏-android.js :-
import React, { Component } from 'react';
import {
AppRegistry,
StyleSheet,
Text,
StatusBar,
View
} from 'react-native';
import { NavigationActions } from 'react-navigation'
import { COLOR, ThemeProvider, Toolbar, Drawer, Avatar } from 'react-native-material-ui';
import Container from '../Container';
import LoginScreen from '../login/LoginScreen';
const uiTheme = {
palette: {
primaryColor: COLOR.green500,
accentColor: COLOR.pink500,
},
toolbar: {
container: {
height: 70,
paddingTop: 20,
},
},
avatar: {
container: {
backgroundColor: '#333'
}
}
};
export default class DrawerMenu extends Component {
constructor(props, context) {
super(props, context);
this.state = {
active: 'people',
};
}
handleLogoutPress = () => {
// AsyncStorage.setItem('SignedUpuser', '');
this.props
.navigation
.dispatch(NavigationActions.reset(
{
index: 0,
actions: [
NavigationActions.navigate({ routeName: 'LoginScreen'})
]
}));
// this.props.navigation.dispatch(NavigationActions.back());
};
_setInfoActive() {
this.setState({ active: 'info' });
}
render() {
return (
<ThemeProvider uiTheme={uiTheme}>
<Container>
<StatusBar backgroundColor="rgba(0, 0, 0, 0.2)" translucent />
<Toolbar
leftElement="arrow-back"
onLeftElementPress={() => this.props.navigation.navigate('DrawerClose')}
centerElement="Menu"
/>
<View style={styles.container}>
<Drawer>
<Drawer.Header >
<Drawer.Header.Account
style={{
container: { backgroundColor: '#fafafa' },
}}
avatar={<Avatar text={'S'} />}
// accounts={[
// { avatar: <Avatar text="H" /> },
// { avatar: <Avatar text="L" /> },
// ]}
footer={{
dense: true,
centerElement: {
primaryText: 'Siddharth',
secondaryText: 'I am DONE now',
},
}}
/>
</Drawer.Header>
<Drawer.Section
style={{
label: {color: '#0000ff'}
}}
divider
items={[
{
icon: 'bookmark-border', value: 'Bookmarks',
active: this.state.active == 'bookmark',
onPress: () => {
this.setState({ active: 'bookmark' });
this.props.navigation.navigate('Bookmark');
},
},
{
icon: 'people', value: 'Connections',
active: this.state.active == 'Connection',
onPress: () => {
this.setState({ active: 'Connection' });
this.props.navigation.navigate('Connections');
},
},
]}
/>
<Drawer.Section
title="Personal"
items={[
{
icon: 'info', value: 'Info',
active: this.state.active == 'info',
onPress: () => {
this.setState({ active: 'info' });
//this.props.navigation.navigate('DrawerClose');
this.props.navigation.navigate('Info');
},
},
{
icon: 'settings', value: 'Settings',
active: this.state.active == 'settings',
onPress: () => {
this.setState({ active: 'settings' });
this.props.navigation.navigate('Settings');
},
},
{
icon: 'logout', value: 'Logout',
active: this.state.active == 'logout',
onPress: () => {
this.handleLogoutPress();
},
},
]}
/>
</Drawer>
</View>
</Container>
</ThemeProvider>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#F5FCFF',
},
header: {
backgroundColor: '#455A64',
},
welcome: {
fontSize: 20,
textAlign: 'center',
margin: 10,
},
instructions: {
textAlign: 'center',
color: '#333333',
marginBottom: 5,
},
});
以上是我在我的应用程序中使用的堆栈架构，你可以看到我的主屏幕是登录屏幕，我在抽屉（侧面菜单）中确实有从应用程序注销的选项。我最想要的是，当用户单击注销时，他/她应该被重定向到登录屏幕。我已经对此进行了谷歌搜索并了解了两种方法，但这两种方法都不适合我，可能是我以错误的方式使用它们。所以我在这里寻求你的帮助。
这两种方法是：-
1)
this.props
.navigation
.dispatch(NavigationActions.reset(
{
index: 0,
actions: [
NavigationActions.navigate({ routeName: 'LoginScreen'})
]
}));
2) this.props.navigation.dispatch(NavigationActions.back());
这个问题对你来说可能看起来很傻，但我真的被困在这一点上，只是想知道我该如何解决这个问题。任何帮助将不胜感激！！！！ 提前致谢。
【问题讨论】：
-
试试这个 this.props.navigation.navigate('LoginScreen');
-
它什么也没做。
-
控制台props，查看props是否有导航或导航相关功能。
