I am working on a React Native app. When the user loads the app, I want the first screen they see to be a Home screen to tell them about some of the features of the app. Currently, I am using a BottomTabNavigator with nested StackNavigators inside. I have been able to get my Home screen added, but it always shows up the in TabNavigator. Is there a way to make a single tab item not present in any of the screens?
PS. I have tried using a StackNavigator as my parent like the following, but my TabNavigator does not show up:
const AppNavigator = createBottomTabNavigator({
Item1: Item1,
Item2: Item2,
Item3: Item3,
Item4: Item4,
Item5: Item5
});
const MainNavigator = createStackNavigator({
Home: Home,
Content: AppNavigator
}
Any ideas?
UPDATE
If I have screens called Item1, Item2, Item3, Item4, Item5, and Home, I want to make it display Home first. In addition, I want the TabBar visible at the bottom, but it can't include the Home screen.
You likely want to nest your main app tab navigator inside another tab navigator like this:
const AppNavigator = TabNavigator({
Main: { screen: MainScreen },
Settings: { screen: SettingsScreen },
});
export default TabNavigator(
{
Home: { screen: HomeScreen },
App: { screen: AppNavigator },
},
{
navigationOptions: ({ navigation }) => ({
tabBarVisible: false,
}),
}
);
I think SwitchNavigator is what do you need https://reactnavigation.org/docs/en/switch-navigator.html. Try like this
const MainNavigator = createSwitchNavigator({
Home: Home,
Content: AppNavigator
}
If you want TabNavigator you can simply do the same
const MainNavigator = createBottomTabNavigator({
Home: Home,
Content: AppNavigator
}
Create a custom tabBarComponent for your Tab Navigator to use.
Map through the routes in that custom tabBarComponent and don't render anything for that Tab if route.routeName === 'Home'.
const TabBar = props => {
return (
{navigation.state.routes.map((route, i) => {
if (route.routeName !== 'Home') {
return (
<Tab...

In My code I want to Hide The Drawer Tab in Tabnavigator.
i will do many tries but its not working. please help me.
const Drawer=createDrawerNavigator({
Home:{screen:Home},
})
const TabNavigator = createBottomTabNavigator({
Drawer:{screen:Drawer},
Home: {screen: Home},
Categories:{screen:Cate},
ShortList:{screen:ShortList},
Account:{screen:Account},
},
}
);
You can't. You can instead pu the tabs inside the drawer so the drawer would be hidden but available on all tabs
const Drawer=createDrawerNavigator({
Tabs:{screen:TabNavigator, navigationOptions: {drawerLabel: () => null}}
Home:{screen:Home}
})
const TabNavigator = createBottomTabNavigator({
Home: {screen: Home},
Categories:{screen:Cate},
ShortList:{screen:ShortList},
Account:{screen:Account},
},
}
);
I started learning React Native, I know how to create TabNavigator or DrawerNavigator but I need access to props.navigation on landing page where I don't have TabNavigation, how I'am supposed to get it.
I tried this:
const App = createStackNavigator({
LandingScreen: { screen: LandingScreen },
Register: { screen: RegisterScreen },
Login: { screen: LoginScreen}});
But still, this.props are empty object.
And what is stackNavigator in plain language, does it just define navigation in order to be able to use navigation ?
In your LandingScreen you can able to get the this.props.navigation. You can show your TabNavigation as your initial route. You can even set Stack Navigation for each Tab. For React Navigation(v2) Documentation https://reactnavigation.org/docs/en/tab-based-navigation.html
Stack Navigation:
Provides a way for your app to transition between screens where each new screen is placed on top of a stack.
//Stack Navigator
const App = createStackNavigator({
Home: { screen: Tabs }, //You can nest your TabNavigator here, Hence the LandingScreen inside your HomeStack will shown as your Initial screen
Register: { screen: RegisterScreen },
Login: { screen: LoginScreen}});
//Sample Tab Navigator
const Tabs = createBottomTabNavigator(
{
Home: HomeStack,
Settings: SettingsStack,
},
{
/* Other configuration remains unchanged */
}
);
const HomeStack = createStackNavigator({
LandingScreen: LandingScreen,
Details: DetailsScreen,
});
const SettingsStack = createStackNavigator({
Settings: SettingsScreen,
Details: DetailsScreen,
});
You can get your navigation Prop by using below
//LandingScreen Component
export default LandingScreen extends Component{
static navigationOptions = ({navigation}) => ({ //you can able to destructure your navigation prop here
headerTitle: 'Langing Page'
})
render(){
return(
//your logic here
)
}
}
I'm using React Navigation in my react native app, and I'm looking to render both the drawer navigation and tab navigation components simultaneously.
At first, I tried to render both in the root app component, but that threw an error that appears in their documentation here. I then attempted the solution listed below, which produced the following for me:
const TabNavigator = createBottomTabNavigator({
Settings: {
screen: SettingsScreen
}
});
const AppNavigator = createDrawerNavigator({
Home: {
screen: HomeScreen
},
Products: {
screen: ProductsScreen
},
TabNav: TabNavigator
});
export default class App extends React.Component {
render() {
return <AppNavigator />;
}
}
The tab navigation only shows when I select the TabNav link in the drawer navigation. I want it on every screen. I also don't want the TabNav label to show in the drawer navigation.
Am I missing something in the documentation, or is this the intended functionality?
For the first question, move the TabNav to first in the navigator like this
TabNav: TabNavigator,
Home: {
screen: HomeScreen
},
Products: {
screen: ProductsScreen
}
or else you change the initialRouteName to "TabNav"
For the Second question,
If you want the TabNavigation to show inside the HomeScreen and ProductsScreen you need to include TabNavigation in both
or they need to have a parent TabNavigation which contains those. I can add a sample code if you post what the TabNav contains.
And for the Third question,
You can use contentComponent in DrawerNavigator example like this
contentComponent: props => (
<AppDrawerContent {...props} navigation={props.navigation} />
),
Edited:
If you want TabNavigator to show on each one. I think you should change the way you Structure your navigator.
export default class App extends React.Component {
render() {
return < TabNavigator />;
}
}
const TabNavigator = createBottomTabNavigator({
Drawer: {
screen: AppNavigator
}
});
const AppNavigator = createDrawerNavigator({
Home: {
screen: HomeScreen
},
Products: {
screen: ProductsScreen
}
});
or else if you want TabNavigator inside each screen individually then
const AppNavigator = createDrawerNavigator({
HomeNavigator: {
screen: HomeScreenNavigator
},
Products: {
screen: ProductsScreen
}
});
const HomeScreenNavigator = createBottomTabNavigator({
Home: {
screen: HomeScreen
},
Settings: {
screen: SettingsScreen
}
});
export default class App extends React.Component {
render() {
return <AppNavigator />;
}
}
Like wise for Products screen also.
What you have actually done is you included the TabNav as Drawer Screen so it does appear in the Drawer side bar.
Even if this structure doesn't work you need to check on restructuring it. Or you may give a images how you want to show it. May be I could help you with better understanding.
I'm looking to use DrawerNavigator along with StackNavigator so I can display a header for my screens, everything is working fine but I messed up with the router logic, my issue is that the drawer do not render items but only the first one.
const Router = StackNavigator({
Home: {screen: Screen1},
Other: {screen: Screen2}
}, {
navigationOptions: {
headerStyle: {backgroundColor: '#333333'},
headerTintColor: '#fff'
}
});
const Drawer = DrawerNavigator({
App: {screen: Router},
});
export default Drawer;
Can someone please explain why I'm only seeing the first item in drawer? When trying to fix that I added a second item to drawer config router like that
const Drawer = DrawerNavigator({
App: {screen: Router},
App: {screen: Router},
});
It add a second item to the drawer but with the wrong title, it use title for screen one but the link is correct, it redirect to the second screen. so how can I fix those labels?
Better way of doing this is by creating drawernavigator with custom "contentComponent". This way you will have more control of what titles you want to display in the drawer, on click of title which screen it has to navigate to, background color of the drawernavigator.
So the DrawerNavigator is instantiated like this (from the docs):
const MyApp = DrawerNavigator({
Home: {
screen: MyHomeScreen,
},
Notifications: {
screen: MyNotificationsScreen,
},
});
Therefore by doing what you did the first time:
const Drawer = DrawerNavigator({
App: {screen: Router},
});
, you're telling DrawerNavigator that there is only one element to be added to the drawer menu, regardless of what that screen "Router" contains, for DrawerNavigator it is just one element.
So in order to correctly add your screens to the drawer:
const HomeRoute = StackNavigator({
Home: {screen: Screen1},
}, {
navigationOptions: { ... }
});
const OtherRoute = StackNavigator({
Other: {screen: Screen2},
}, {
navigationOptions: { ... }
});
const Drawer = DrawerNavigator({
Home: { screen: HomeRoute },
Other: { screen: OtherRoute }
});
export default Drawer;
I hope i'm able to explain this properly, and that there isn't already an answer out there. It seems there is still a few design decisions up in the air for apps that have a StackNavigator nested inside DrawerNavigator.
What I'm trying to achieve: I have a link to a "Settings" screen in my DrawerNavigator, similar to a lot of apps. I will use Google Play Music as an example for what I want. Clicking on "Settings" sends you to a new screen with only a "back" / "done" button. The Drawer Menu is not accessible.
Question: How can I add a link in the DrawerNavigator that links to a new card/modal view? I'm guessing it can be achieved my some nested navigator stack, but I haven't been able to get anything that works.
Sample code:
const DashboardNavigator = StackNavigator({
Home: { screen: HomeScreen }
})
const SettingsNavigator = StackNavigator({
Settings: {screen: SettingsScreen}
// I thought adding 'mode': 'modal would give me the functionality
// I'm looking for my it doesn't
}, { mode: 'modal', initialRoute: 'Settings' })
const DrawerNavigation = DrawerNavigator({
Home: {
screen: DashboardNavigator
},
Settings: {
screen: SettingsNavigator
}
})
There is a pull request to allow disabling the Drawer Menu on specific screens so i'm not really worried about that right now, but just navigating to a screen where navigation.goBack() takes me back to the last screen I was on (with the card slide animation).
Was able to get it with this, although I still can access the Drawer menu... Hopefully they add the ability to disable the Drawer soon.
const DrawerComponent = ({ navigation }) => {
return (
<View>
<Button onPress={() => navigation.navigate("SettingsView")} title="settings" />
</View>
)
}
const DashboardNavigator = StackNavigator({
Home: { screen: HomeScreen },
SettingsView: { screen: SettingsScreen }
})
const DrawerNavigation = DrawerNavigator({
Home: {
screen: DashboardNavigator
}
}, { contentComponent: DrawerComponent })
const RootNavigator = StackNavigator({
Root: {
screen: DrawerNavigation
}
})
