I'm trying to right align my header title in my react native app but can't seem to do so. In react navigation, you can set headerTitleAlign prop only to center and left. I try to use headerRight and remove headerTitle but the default title kicks in which is the name of the screen.
Had a search online but no answers has cropped up.
Wrap your header inside a view. And pass this style ={{alignItems: 'flex-end', alignContents: 'flex-end'}}

I use react native navigation and Expo in my project. Everything works as expected but the header on the web is not fixed. How can I keep it on top even by scrolling the page?
I tried many thing like cardStyle: { flex: 1 } in screenOptions but nothing works.
"expo": "^47.0.6",
React native navigation V6
The header can be styled as desirder through Screen -> options -> headerStyle
There's more info in the docs: https://reactnavigation.org/docs/headers/#adjusting-header-styles
I set up an Expo Snack with React Navigation v6, with a ScrollView including a few squares, so you can scroll: https://snack.expo.dev/#p-syche/header-styles
I resolved this specific problem separating in different files the navigation components, with this way the component doesn't rerender anymore
First of all: i'm using React Native. I have a TabNavigator nested into a DrawerNavigator
i'm trying to change the color of the drawer header based on a specific screen into the Material Top Tab Navigator.
I tried to do it with screenListeners of the TabNavigator with a boolean state but when i made a setState the TabNavigator is rerendered and jump to the Home screen again.
PD: The App have a top header from the drawer and the bottom tab from the tabNavigator. I need that both of them change the color when X screen is focus.
To do this for the bottom tab i used route.name but i can't access to this property from the parent navigator.
....
screenOptions={({route}) => ({
tabBarStyle: {
backgroundColor:
route.name === '[targetScreen]' ? '#6600A1' : theme.PRIMARY_COLOR,
},
...
There are various options to provide a state in both directions, Redux, Recoil, Context Provider. If you are not already using one of them I think the Context Provider is the easiest. Basically it is a container around your outer navigator and inside you can access and change the state.
I am working on a react-native app using react navigation.
I want to add a partial modal that covers 30% of screen when pressing on one of the tabs in the bottom-tab, similar to the "+" tab in the YouTube app:
Youtube modal
I've tried to use react-native Modal component, but
I have problems with activating it from bottom tab
it covers whole screen
Any suggestions?
Thanks..
To answer your question 100% correct I'd need to know more details about your project but, I can try to explain how can be your logic to do this withou any libs.
You can create another component called "Start" where you're gonna put your Modal with absolute position above your navigator.
You can create a Modal that will be above your navigator:
export const Start(){
return(
<View style={{flex:1}}>
<Modal>
<View/>
</Modal>
<NavigatorComponent/>
</View>
)
}
This is going to work because when you put a component with absolute position above the other, this component stay in front of the below component. In your case, will stay in front of everything including the TabBar.
To the modal has just 30% of the height you just need to put in its styles the attribute height: '30%'.
In the initial component of your App (usually the index.js file), you just return the new Start component.
I hope you like my answer. Please, if you have more questions you can ask. Waiting for your feedback :).
I have a materialTopTabNavigator in my app and one of the screens needs to have the swiping between tabs gesture enabled on only part of the screen (for example, from the bottom of the screen to 200 from bottom). I think I should be able to do this with gestureHandlerProps prop of the materialTopTabNavigator, but it doesn't seem to work. This prop allows you to pass props to the underlying PanGestureHandler. Here is what I am passing as gestureHandlerProps and the link to the PanGestureHandler docs:
gestureHandlerProps={{
maxPointers:1,
failOffsetY:height-200,
hitSlop: {left:0, right:0, top:0, bottom:200}
}}
//height is height of screen
Link to PanGestureHandler Docs: https://docs.swmansion.com/react-native-gesture-handler/docs/handler-pan
I figured out how to do this using the common handler props listed in the react-native-gesture-handler docs. I used the hitSlop prop and passed it an object with height and top properties as follows. This was passed to my material top tabs navigator gestureHandlerProps prop.
gestureHandlerProps={{
maxPointers: 1,
hitSlop: {height: 100, top: 0}
}}
This allows the underlying PanGestureHandler of the material top tabs navigator to only be activated from 100 points from the bottom of the screen.

I made my own Header component in TabNavigator (react-navigation).
When I'm swiping between tabs, every component is swiping as well.
Is it possible to make fixed Header during swiping between different tabs?
Add headerMode :float in navigation options of TabNavigator, as mentioned in this link react-navigation
Wrap the Navigator in a root view then provide header inside the view
Pseudo code wll look like
<View>
<Header/>
<TabNavigator/>
</View>
Header will remain constant while the tab navigator works as indented
