I want to be able to swipe between the screens, and on the third screen the swipe to the next screen must be disabled and it should happen through a click on a button.
So far I was unable to remove the header from the screen which must happen first.
const loginNavigation = createMaterialTopTabNavigator({
firstLogin: LoginFirstScreen,
secondLogin: LoginSecondScreen,
thirdLogin: LoginThirdScreen,
fourthLogin: startingNavigation
},{
headerMode: 'none',
navigationOptions: {
headershown: false,
}
})
the answer to this is the following.
const loginNavigation = createMaterialTopTabNavigator({
firstLogin: LoginFirstScreen,
secondLogin: LoginSecondScreen,
thirdLogin: LoginThirdScreen,
fourthLogin: startingNavigation
},{
swipeEnabled: true,
tabBarOptions: {
style: {display: "none"}
}
})
Add headerMode null instead of none
Try to use this option header: null in place headerMode: 'none'

I am using React Native and React Native Navigation to build out my application. Currently, I have three bottom tabs: Home, Upload Video and Messages. Upon selection of the Upload Video tab, I want to render the Upload Video component and hide the bottom tabs on just that screen, and display a header with 'Cancel' (takes them back to the HomeView) and 'Post' buttons (this has already been done). I've had an extremely difficult time hiding the tab bar on this specific screen.
I tried following the code here (How can I hide the bottom tab bar on a specific screen (react-navigation 3.x)); however, that ended up being unsuccessful and I was not able to hide the bottom tabs on any of the screens this way.
Currently, I have this as my bottom navigator:
const BottomTabNavigator = createBottomTabNavigator({
HomeView: {
screen: HomeView,
},
VideoView: {
screen: VideoSelectionView
},
Messages: {
screen: SearchView
}
});
Any insight would be extremely helpful, thanks.
I've traversed the internet like never before to find a solution for this problem as the provided solution by the docs did not work in the slightest.
I had the following navigational Set-Up:
Bottom Tabs
A (NativeStack)
1 (Screen)
2 (Screen)
3 (Screen)
B (NativeStack)
C (NativeStack)
I wanted to hide the bottom bar in Screen 1. What finally did the trick was the following snippet in the corresponding screen:
useEffect(() => {
navigation.getParent()?.setOptions({
tabBarStyle: {
display: "none"
}
});
return () => navigation.getParent()?.setOptions({
tabBarStyle: undefined
});
}, [navigation]);
The effect is run when the navigation prop updates and with that implicitly after the screen is being opened. With getParent() I get the bottom tabs navigator and can set the options with setOptions(...). To bring the bottom tabs back one has to manually set the options. I solved this by returning the method that resets the tabBarStyle in the call of useEffect(). This call is being made when it's time to clean-up, meaning that it will run as soon as the screen is being unmounted.
May this save same of you of the desperation I had to go through.
You need to specify for each TabBar screen or stack for which you need to hide tabbar,
const BottomTabNavigator = createBottomTabNavigator({
HomeView: {
screen: HomeView,
navigationOptions:()=>{
return {
tabBarVisible:false,
};
}
},
VideoView: {
screen: VideoSelectionView
},
Messages: {
screen: SearchView
}
});
on v5 you can modify options using a function and default arg navigation.:
<BottomTab.Screen
name="Explore"
component={Explore}
options={({ navigation }) => {
const { routes, index } = navigation.dangerouslyGetState();
const { state: exploreState } = routes[index];
let tabBarVisible = true;
if (exploreState) {
const { routes: exploreRoutes, index: exploreIndex } = exploreState;
const exploreActiveRoute = exploreRoutes[exploreIndex];
if (exploreActiveRoute.name === "RewardDetail") tabBarVisible = false;
}
return {
tabBarVisible,
title: "Explore",
tabBarLabel: "Explore",
tabBarIcon: ({ color, size }) => (
<AntDesign name="search1" color={color} size={size} />
),
};
}}
/>

Since react-navigation 5 is now being used, the above solution doesn't work anymore.
For React-Navigation 5, refer to this link.
In React Navigation V6 add display: none in options under tabBarStyle.
Add tabBarButton: () => null, to disable icon in Tab.
<Stack.Screen
name="Add Product"
component={AddProduct}
options={() => ({
tabBarStyle: {
display: "none",
},
tabBarButton: () => null,
})}
/>
Just setting the tabBarStyle to none doesn't work for me, I needed to use the property tabBarVisible too, if using hooks you can do something like that:
export function useHideBottomBar() {
const navigation = useNavigation();
useEffect(() => {
navigation.getParent()?.setOptions({ tabBarStyle: { display: 'none' }, tabBarVisible: false });
return () =>
navigation.getParent()?.setOptions({ tabBarStyle: undefined, tabBarVisible: undefined });
}, [navigation]);
}
In React navigation 5+ I used the following approach to hide a tab bar on a specific screen which was inside a stack navigator of a tab screen. In my tab navigator containing file I made a function, and then set the options property using the function which will trigger dynamically.
function getIsTabBarShown(route) {
const routeName = getFocusedRouteNameFromRoute(route) ?? routes.DASHBOARD;
switch (routeName) {
case routes.MEMBERDETAILS:
return false;
default:
return true;
}
}
This function will return false when user would go to MemberDetails Page which is inside MemberNavigator Stack.
<Tab.Screen
name="MemberTab"
component={MemberNavigator}
options={({ route }) => ({
title: 'Members',
tabBarVisible: getIsTabBarShown(route),
tabBarIcon: ({ color, size }) =>
<MaterialCommunityIcons name="account-group" color={color}
size={size} />
})} />

After searching and trying a lot of methods I changed the top element View to Modal then hid bottombar, because modal can be upper bottom bar. It's not the best but still useful.
<View>
//code block
</View>
to->
<Modal animationType='fade' transparent={false} visible={true}>
/code block
</Modal>
In Version 6 this worked for me:
To hide the bottom tab navigator from the screen:
navigation.getParent()?.setOptions({tabBarStyle: {display: 'none'}});
To show the bottom tab navigator from the screen:
navigation.getParent()?.setOptions({tabBarStyle: {display: 'flex'}});
just on the Screen you want to hide the bar, set tabBarVisible: false.
<Tab.Screen
name="SignIn"
component={SignInScreen}
options={{
tabBarVisible: false, //like this
tabBarButton: (props) => null, //this is additional if you want to hide the tab element from the bottom nav
}}
/>
I have a loader in place but in loads under the header. What i need is too hide or make the header transparent when the loader is loading and again reshow or unhide the header when the loader is ended !
How to implement that ?
As of now am using this,
static navigationOptions = ({ navigation }) => {
return {
title: navigation.getParam('from'),
headerStyle: {
backgroundColor: '#673AB7',
},
headerTitleStyle: {
color: '#fff'
},
headerTitleAlign: 'center',
headerTintColor: '#fff'
}
};
Can this be changed dynamically ? if so how is it ? please guide !
Am using react navigation 4x
You can use:
const loading = <Some state to be received as a prop whether the loader is loading>
stackName: {
screen:ComponentScreenName,
navigationOptions: {
headerShown: !loading
}
}
there is a static navigationOptions you can use for screens prior to version 5.
you can update these props based on state
static navigationOptions = {
headerShown: !isLoading,
};
after react-navigation v5 you use setOptions for same functionality.
I'm trying to set up a MaterialBottomTabNavigator in my app with custom icons using react-native-vector-icons, but the icons are not showing up. Am I doing something wrong in the NavigatorConfig?
At first I thought it was because my icons aren't loading in correctly, but placing them in a View on another screen (anywhere but inside the MaterialBottomTab) makes them show up no problem. Even the standard MaterialIcons provided with vector-icons aren't showing up in the bottomTab, but any other place is no problem.
I've tried shifting the configs around, placing the tabBarIcon in both the screen config, aswell as the navigator config, but still no result.
I've also tried the showIcon option, but also no results.
Here's my code right now:
export const userNavigation = createMaterialBottomTabNavigator({Bars, Settings}, {
Bars: {
screen: Bars,
navigationOptions: {
tabBarIcon: ({focused}) => <Icon name="bars" size={20} color={focused ? '#FFF' : '#DACE91'}/>,
},
},
shifting: false,
labeled: true,
activeColor: '#FFF',
inactiveColor: '#DACE91',
});
I expect the icons to show up in the bottomTab, but I get no error messages or any other feedback as to why they aren't showing.
You are putting in the tab configs the route configs.
createMaterialBottomTabNavigator({
Bars:{
screen: Bars,
navigationOptions:{
tabBarIcon: ({focused}) =><Icon name="bars" size={20} color={focused ? '#FFF' : '#DACE91'}/>,
}
}
},{
shifting: false,
labeled: true,
activeColor: '#FFF',
inactiveColor: '#DACE91',
})
Hopefully this will help!
to fix then icon
add these in bootom navigation
shifting: false,
labeled: true,
How can I give a custom navigation to the header back arrow in ReactNavigation? I want the back arrow in the header to navigate to the screen I define and not to the previous screen.
Thanks.
You could try 2 things:
a) use headerMode: 'none' in your sub-StackRouters instead of your root router (named RouterComponent). Ideally you shouldn't have to do anything more then and the headers of the sub-StackRouters would be displayed in your root router's header. I think I remember something similarly worked a while back for me, but I haven't tested it in a while now and I think it's unlikely that it will still work like this but you can test nevertheless.
b) and this is what I'm currently using in a different situation. To manually include the back button:
import { HeaderBackButton } from '#react-navigation/stack';
const navigationOptions = ({ navigation }) => ({
headerLeft: <HeaderBackButton onPress={() => navigation.goBack(null)} />,
})
const RouterComponent = StackNavigator({
Tabs: {
screen: Tabs
},
Profile: {
screen: ProfileStack,
navigationOptions
}
},{
mode: 'modal',
headerMode: 'none',
});
If above solution doesn't work,
Try to add navigationOptions directly to the ProfileStack definition.
const ProfileStack = StackNavigator({
ProfileHome: {
screen: ProfileHome,
navigationOptions: ({navigation}) => ({ //don't forget parentheses around the object notation
title: 'Profile',
headerLeft: <HeaderBackButton onPress={() => navigation.goBack(null)} />
})
},
ProfileEdit: { screen: ProfileEdit }
}
Hi who ever is using react-navigation 5.x you might not be able to make navigation using navigationOptions. The option is been replaced with options.
Say your in screen -1 and navigated to screen-2 and then to screen-3. By default using react-navigation you can navigate from screen-3 to screen-2. But if you want customised navigation i.e., Say from above example if you want to navigate from screen-3 to screen-1.
If you would like to retain the view of back button and only override the onPress method, you can import { HeaderBackButton } from '#react-navigation/stack' and assign that component to the headerLeft option.
Example:
<RootStack.Screen
name="dashboard"
component={Dashboard}
options={({navigation, route}) => ({
headerLeft: (props) => (
<HeaderBackButton
{...props}
onPress={() => navigation.navigate('Home')}
/>
),
})}
/>
In above example on click of back button in Dashboard screen takes you to Home screen.
Enjoy & Thanks

How to implement the count inside the tab navigator in react native.Below is the example image. I have asked react communities but nobody seems to have an answer for this.
Please Help.
You have two options here:
1.Use redux or something else so that your tab component knows its own count, regardless of the route.
2.You can have a param like badgeCount, which is visible because tabBar or any other navigation option can be defined as a function of the navigation prop:
static navigationOptions = {
tabBar: (navigation) => ({
label: 'Home',
icon: ({ tintColor, focused }) =>
<IconBadge
MainElement={
<Ionicons
name={focused ? 'ios-home' : 'ios-home-outline'}
size={26}
style={{ color: tintColor }}
/>
}
badgeNumber={navigation.state.params.badgeCount}
/>,
}),
}
Then you can change the param by calling navigation.setParams({ badgeCount: 123 }).
This has been addressed in this Github issue
In your Past Page:
static navigationOptions = ({navigation}) => ({
title: 'yourTitle',
tabBarLabel: 'Past${navigation.state.params.count}'
})
and it will display new count after you change the count by setParams method:
navigation.setParams({count: list.length})
