I am using SwitchNavigator from React-navigation for Authentication in React-native app. In the Authorized Section, I want to show a side Drawer for showing options like settings and log out. Entering into the Authorized section by clicking the button in tabs section user should be able to go to details section of an album. For that, I am using StackNavigator.
Issue:
After Authentication, Once I navigate to a section with Side Drawer in which stack navigator is present, nothing is rendered once navigated to Authorized section. Even the Test screen is mounted(checked through componentDidMount) nothing is displayed.
const Stages = createMaterialTopTabNavigator({
testStage1: { screen: TestScreen },
testStage2: { screen: TestScreen },
testStage3: { screen: TestScreen },
testStage4: { screen: TestScreen },
})
const AuthorizedSectionRouteConf={
navigation:{
stages: {
screen : Stages,
},
details : {
screen: DetailsScreen,
}
},
navigationOptions:{
headerLeft:null
}
}
const AuthorizedSectionNavigator =
createStackNavigator(AuthorizedSectionRouteConf.navigation);
const Config = {
navigation: {
UnauthorizedSection: {
screen: ({navigation}) => <LoginScreen navigate={navigation.navigate}/>,
navigationOptions:{
header:null,
mode:'modal'
}
},
AuthorizedSection: {
screen: createDrawerNavigator({
Home:{
screen: ({navigation}) => <AuthorizedSectionNavigator screenProps={{drawerNavigator:navigation}} />
}
})
},
TestSection: TestScreen
}
}
export default AppNavigator = createSwitchNavigator(Config.navigation);
Navigation after navigation:
this.props.navigate('AuthorizedSection')
==> nothing is visible after this.
However, If I navigate to TestScreen after Authentication which is simple text on screen
it rendered properly.
this.props.navigate('TestSection')
==> working properly
Figured out that there is no space for the component to render. Fixed it by setting the flex property for the parent container.

I have both a Stack Navigator and a Bottom Tab Navigator:
const App = StackNavigator({
ScreenA: { screen: ScreenA },
ScreenB: { screen: ScreenB },
ScreenC: { screen: ScreenC },
BottomTabNavigator: { screen: BottomTabNavigator}
});
const BottomTabNavigator = BottomTabNavigator({
BottomScreenA: { screen: BottomScreenA },
BottomScreenB: { screen: BottomScreenB },
BottomScreenC: { screen: BottomScreenC},
App: { screen: App}
});
Sometimes, I need to do nested navigation from a BottomTabNavigator component to a StackNavigator component. Thus, I need to add the App screen in my BottomTabNavigator. However, I don't want this screen to be in my Bottom icons, in terms of design. I really want this App screen just for navigation purpose.
Is there a way to get rid of this screen in the bottom icons? If not, do you have any suggestions on how I could re-design the screens/ Stacks ?
React Native activeTintColor not getting applied on selected drawer item. My react native navigation routes looks like,
-> DrawerNavigator
-> StackNavigator
-> HomeScreen
-> FirstScreen
-> SecondScreen
-> ThirdScreen
routes.js
const RootStack = createStackNavigator(
{
Home: { screen: HomeScreen },
ChapterGroup: { screen: ChapterGroupScreen },
Chapter: { screen: ChapterScreen },
}
const DrawerStack = createDrawerNavigator(
{
Home: {
screen: RootStack,
params: { id: 1 }
},
Kural: { screen: ChapterGroupScreen, params: { id: 2 } },
Detail: { screen: ChapterGroupScreen, params: { id: 3 } }
}, { contentComponent: DrawerComponent}
}
export default DrawerStack;
I managed to display the First, Second, thirdScreens on the sidebar by creating a new DrawerComponent which will navigate to the appropriate stack screen on drawer item click.
DrawerComponent.js
resetStack = route => {
let pressedDrwaerItem = route.route.key;
let id = route.route.params.id;
this.props.navigation.dispatch(
StackActions.reset({
index: 1,
actions: [
NavigationActions.navigate({
routeName: "Home"
}),
NavigationActions.navigate({
routeName: "ChapterGroup",
params: { title: pressedDrwaerItem, no: id }
})
]
})
);
}
render() {
return (<ScrollView>
<DrawerItems
{...this.props}
onItemPress={this.resetStack}
</DrawerItems</ScrollView>)
}
It properly gets navigated to the ChapterGroup Screen on Home stack but the drawer activeitem points to the Home not the second or third custom name. I think it may be because all the other screen exists inside the Rootstack. Is there anyway to manually set the second drawer item as active?
or any successful implementation of DrawerNavigator inside StackNavigator ? ie. I want to use two screens from stack navigator as drawer items. And if we navigated through to that particular screen from home screen, the corresponding drawer item should be selected.
Not sure whether you have tried contentOptions or not, but this is what i have found from react-navigation document
contentOptions for DrawerItems
There are various property you can use with contentOptions
contentOptions: {
activeTintColor: '#e91e63',
itemsContainerStyle: {
marginVertical: 0,
},
iconContainerStyle: {
opacity: 1
}
}
From above snippet i guess for you activeTineColor might be useful.
I'm not sure about your intentions with the resetStack function.
If you use the following function instead, it's going to work:
navigateToScreen = (route) => {
const navigateAction = NavigationActions.navigate({
routeName: route.route.key
});
this.props.navigation.dispatch(navigateAction);
}
//...
<DrawerItems
{...this.props}
onItemPress={this.navigateToScreen}>
</DrawerItems>
It sets the new screen without stacking it up. It sets the activeTintColor though.
I omitted the params passing to make it simple.
I would like to hide the Back button in the top-left corner, but I don't have any idea how to do it with react-navigation or react-native.
Just tried to use static navigationOptions = { header: null } but the < Back button was still alive.
I was using Modal and it works, but I want to know how to hide < Back button without using Modal.
Thank you in advance!
Using headerLeft: () => <></> works great in iOS, but in Android was still displaying the default back button.
I was able to hide it by adding the headerBackVisible: false on the screenOptions of the Stack Navigator or you could include it on the options for every Stack Screen.
More info at https://reactnavigation.org/docs/native-stack-navigator/#headerbackvisible
I suppose you're using a StackNavigator and that you don't want a header.
You need to use headerMode: none in the StackNavigatorConfig.
For example:
const ModalStack = createStackNavigator(
{
HomeScreen: { screen: Home },
ModalScreen: { screen: Modal },
},
{
headerMode: 'none',
mode: 'modal',
}
);
More info in the react-navigation docs.
It depends upon the react navigation version you're using, try this
const ModalStack = createStackNavigator(
{
HomeScreen: { screen: Home },
ModalScreen: { screen: Modal },
},
{
headerMode: 'none',
header: null
}
);
if it is StackNavigator default config, go to StackNavigator:
defaultNavigationOptions: {
header: null,
},
const Stack = createStackNavigator();
<Stack.Navigator screenOptions={{headerShown: false}}>
createStackNavigator is a function that returns an object containing 2 properties: Screen and Navigator. Both of them are React components used for configuring the navigator.
Now below Stack.Navigator, you can place your screens using <Stack.Screen name="Home" component={HomeScreen} />. In name, you can give any name, and in component give the name of your component.
I want a simple functionality of logging out from drawer item press. For that i have done this:-
const HomeNavigator = DrawerNavigator(
{
Splash: { screen: SplashScreen }
}
)
This adds an item in drawer and on clicking it app navigates to splash screen. But with this method i could not achieve whole functionality of logging out. i.e:-
Clearing the screen stack so that on back press app shouldn't go back to screen with drawer.
App should navigate from splash to login screen after logging out.
My above solution not letting me do both these things. Is there a better way to achieve my requirement?
Update
My Navigation structure so far is somewhat like this:-
StackNavigator(
Splash: {screen: SplashScreen},
Login: {screen: LoginScreen},
Home: {screen: HomeScreen},
)
HomeNavigator = DrawerNavigator(
Logout: {screen: SplashScreen}
)
HomeScreen{
render(){
return <HomeNavigator navigation={this.props.navigation} />;
}
}
You can see i am using SplashScreen in both navigators. In stack it's the first screen while in drawer it's used for logging out. but when i navigate from drawer screen to splash i lose the StackNavigator that i created before for splash to login navigation. Can you suggest me any better way to do it?
You can call this function in the componentWillMount(){} of the Splash Screen:
clearStack = (routeToGo) => {
const resetAction = NavigationActions.reset({
index: 0,
actions: [
NavigationActions.navigate({ routeName: routeToGo })
]
})
this.props.navigation.dispatch(resetAction)
}
Importing {NavigationActions} from react-navigation.
You can also create a custom drawer navigator by using the contentComponent prop in the DrawerNavigatorConfig, in which you can change the onPress of the navItems to do whatever you want, like calling the function to clear your stacks.
UPDATE: on your Splash Screen
componentWillMount(){
this.clearStack('Login')
}
As a newbie in react-native i'm trying find a way to use react-navigation with different files without a navbar to navigate (for example just click on a button in the login view to enter the main view, clicking on log out button return to login view).
With react-navigation i made a global component 'Nav' and i placed in the main AppRegistry call:
AppRegistry.registerComponent('myApp', () => Nav);
While in the Navigator.js:
export const Nav = StackNavigator({
Login: { screen: LoginView },
AddStream: { screen: AddStreamView },
});
When i run
react-native run-android
i get the first view loaded under a white space (it should be the navigator, that i don't want in my app)
Now how can i remove the Nav from the view and how can i change View onPress a button component in another file?
There is another package that fill better my desire?
From the docs, setting the the headerMode to none should do the trick. This will hide the header on all of the screens defined in that StackNavigator. Example:
const Nav = StackNavigator({
Login: { screen: LoginView },
AddStream: { screen: AddStreamView },
},{
headerMode: 'none',
});
If you want to control the visibility of the header so that it appears on some of the screens but not all of them, then you can set headerMode to screen and for each individual screen set [the navigation prop for header: { visible: false }. See docs here. For example, if you are creating the screen component in another file, it might look like this:
// In the main file:
const Nav = StackNavigator({
Login: { screen: LoginView },
AddStream: { screen: AddStreamView },
},{
headerMode: 'screen',
});
// Hidden for your Login screen:
export default class LoginView extends Component {
static navigationOptions = {
header: { visible: false }
}
// etc...
}
// Visible for your AddStream screen:
export default class AddStreamView extends Component {
static navigationOptions = {
header: { visible: true }
}
// etc...
}
Edit: missed the second part of your question.
For navigating to a different screen, you really should go through the Hello World tutorial as it explains it. Specifically, this section. Relevant example code from the tutorial:
render() {
const { navigate } = this.props.navigation;
return (
<View>
<Text>Hello, Chat App!</Text>
<Button
onPress={() => navigate('Chat')}
title="Chat with Lucy"
/>
</View>
);
}
In your case, 'Chat' would be either 'Login' or 'AddStream'.
