I'm beginning in React Native development.
I've spend many hours on something but I'm still blocked.
I have a "header" view and under the view, a Stack navigator and inside a tab navigator.
When I open the stack navigator (with the Login Button), I would like to put the new view above the "header", without hiding him to avoid ugly effect when the new view appears.
Here an example when I put a negative margin top on the stacknavigator, but it stays behind the header
Is there any other way to do this properly ?
Thanks.
For information, I've started from the React Native boilerplate "Pepperoni App Kit", added my custom header before the AppNavigator, and hidden the headers on the Tab navigator.
Instead of having header under View, you should have use headerMode:'screen' option with StackNavigator. You can control the visibility of header under each sub navigator using the navigation options.
Here is sample snippet
export const Root = StackNavigator(
{
Tabs: {
screen: HOViewPager,
navigationOptions: {
title: "Title",
header: <Header />,
},
},
login: {
screen: Login,
navigationOptions: {
headerMode: "none",
header: null,
},
},
imageoverlay: {
screen: HOImageOverlay,
navigationOptions: {
headerMode: "none",
header: null,
},
},
},
{
mode: "modal",
headerMode: "screen",
}
);

I am using navigation drawer in react native & on dashboard initial route i have javascript graph & when i navigate to other pages & come back i want to optional refresh it. It depends from which page user is coming from for example if user navigates to detail page & come back graph should not refresh & incase user navigates to come other screen like help screen & come back it should not refresh.
I found a way to not the refresh routes were to put unmountInactiveroutes in drawer options, but then all routes where not refresh which was hard to maintain.
Another option i tried using memo to remember dashboard component state but it is not working.
Any clue will be appreciated.
const Drawer = createDrawerNavigator({
Home: {
screen: Home
},
.....
SearchResultPage :{
screen: SearchResultPage
}
}, {
initialRouteName: AppConstants.NAV_HOME,
//unmountInactiveRoutes: true,
navigationOptions: {
headerVisible: false
},
headerMode: AppConstants.NONE,
contentComponent: props => <Sidebar {...props}/>
})
const AppNavigator = createStackNavigator({
Drawer: {
screen: Drawer,
navigationOptions: {
header: null
}
}
}, {
initialRouteName: AppConstants.NAV_DRAWER,
//unmountInactiveRoutes: true,
headerMode: AppConstants.NONE
})
let AppContainer = createAppContainer(AppNavigator);
In my React Native app, there is a drawer navigator nested inside a stack navigator. I want to hide stack navigator header inside all drawer navigator screens, but visible in other screens.( Therefore, setting headerMode: none for all screens is not a solution )
This is what I tried, but is not working.
DrawerNav: {
screen: DrawerNavigator,
navigationOptions: {
headerMode:'none'
}
}
Pass header: null as navigationOtpions as shown below.
const DrawerNavigator = createDrawerNavigator(
{
Home: {
screen: YourScreen,
},
},
{
navigationOptions: {
header: null,
},
},
);
I am trying to replicate Popup behaviour(Modal) using react-navigation. I am able to replicate some parts of it but I am not able to generate the complete result. I have to put the tabBar in the Background of the screen. I don't want to hide it. I am using Navigation it gives me some significant advantages over Modal.
I have tried using tabBarVisible: false but it hides the tabBar completely. I am using mode: 'modal' to have the modal behaviour and using TouchableHighlight to close the Modal if pressed on the empty part of the screen. I am not able to overlap the tabBar like the images I have attached below.
This is my code:
const SpaceTabNavigator = createStackNavigator({
Spaces: {
screen: SpacesTab
},
applianceList: AppliancesList,
applianceConfig: ApplianceConfig
},
{
initialRouteName: 'Spaces',
headerMode: 'none',
navigationOptions: {
headerVisible: false,
},
mode: 'modal',
transparentCard: true,
cardStyle: {
opacity: 1
},
})
const TabNavigator = createBottomTabNavigator({
Dashboard: {
screen: HomeTab,
},
Spaces: SpaceTabNavigator,
Moods: MoodStackNavigator,
},
{
swipeEnabled: true,
animationEnabled: true
})
const DrawerNavigator = createDrawerNavigator(
{
TabNav: TabNavigator
},
{
contentComponent: Drawer
}
);
Can you please suggest a way around it?
Here is the result I have achieved yet: The achieved Result
Here is the result I want: This is the result I want
Step - 1 : Make the modal transparent by using the 'transparent' prop from the modal.
Step - 2 : Give the modal margin bottom lets say 50 to render it above the tab bar.
This shall do it
I am new to React Native development, so sorry if this seems obvious.
I have a new app that uses React Navigation Drawer as its main method of navigation. How can I have an onPress function within a page that navigates to a component that is not in my Navigation Drawer?
this.props.navigation.navigate('example') only seems to work for pages defined in the drawer.
My Drawer config:
const MyApp = createDrawerNavigator({
Interactive: {
screen: (props) => <Interactive {...props}
list={[
{ name: "First" },
{ name: "Second" },
{ name: "Third" },
{ name: "Fourth" },
{ name: "Fifth" },
{ name: "Sixth" },
{ name: "Seventh" },
{ name: "Eighth" },
]} />,
},
Settings: {
screen: SettingsScreen,
},
},
I am pressing a button within "Interactive" that should navigate to a component that is not include in the config above.
You can have multiple navigators inside your application (and usually this is the case), and actually every screen you want to navigate to should be defined inside a navigator. Every key in a navigator can be a single Screen or another navigator (Stack-, Drawer-, Tab- or SwitchNavigator).
const DrawerRoutes = createDrawerNavigator({
// your drawer navigator implementation ...
});
const MyApp = createSwitchNavigator(
{
Drawer: DrawerRoutes,
Example: YourScreen, // this would be the screen you want to navigator to
},
{
initialRouteName: 'Drawer'
}
);
And now you can navigate to YourScreen by simply calling this.props.navigation.navigate('Example') from within your Drawer.
In a react-navigation application it is not unusual to have a large combination of nested navigators, but there is always one root navigator.
Using the React Navigation tab navigator https://reactnavigation.org/docs/navigators/tab how do I make one of the tab buttons push the screen up as a full screen modal? I see the stack navigator has a mode=modal option. how do I get that mode to be used when clicking on the TakePhoto tab button? Clicking on it currently still shows the tab bar on the bottom.
const MyApp = TabNavigator({
Home: {
screen: MyHomeScreen,
},
TakePhoto: {
screen: PhotoPickerScreen, // how can I have this screen show up as a full screen modal?
},
});
Actually, there is no support in react-navigation to change the way of presentation on the fly from default to modal (see the discussion about this here). I ran into the same issue and solved it by using a very top StackNavigator with headerMode set to none and mode set to modal:
const MainTabNavigator = TabNavigator(
{
Tab1Home: { screen: Tab1Screen },
Tab2Home: { screen: Tab2Screen }
}
);
const LoginRegisterStackNavigator = StackNavigator({
Login: { screen: LoginScreen }
});
const ModalStackNavigator = StackNavigator({
MainTabNavigator: { screen: MainTabNavigator },
LoginScreenStackNavigator: { screen: LoginRegisterStackNavigator }
}, {
headerMode: 'none',
mode: 'modal'
});
This allows me to do the following (using redux) in Tab1Screen and Tab2Screen to bring up the modal view from wherever I want:
this.props.navigation.navigate('LoginScreenStackNavigator');
Not sure if this is still relevant for you, but i've managed to find away to achieve this.
So i've managed to get it working by using the tabBarComponent inside the tabNavigatorConifg, you can stop the tab navigation from navigating depending on the index.
tabBarComponent: ({jumpToIndex, ...props, navigation}) => (
<TabBarBottom
{...props}
jumpToIndex={index => {
if (index === 2) {
navigation.navigate('camera')
}
else {
jumpToIndex(index)
}
}}
/>
)
Once you've done this, my method of showing the view modally on top of the tab views was to put the tabnavigator inside of a stacknavigatior and then just navigate to a new screen inside of the stacknavigator.
react-navigation's bottomTabNavigator has a tabBarOnPress navigation option you can use to override tab presses:
https://reactnavigation.org/docs/en/bottom-tab-navigator.html#tabbaronpress
const AppContainer = createStackNavigator(
{
default: createBottomTabNavigator(
{
TAB_0: Stack0,
TAB_1: Stack1,
TAB_2: Stack2,
TAB_3: View // plain rn-view, or any old unused screen
},
{
defaultNavigationOptions: {
// other tab navigation options...
tabBarOnPress: ({ navigation, defaultHandler }) => {
if (navigation.state.key === 'TAB_3') {
navigation.navigate('tabToOpenAsModal');
} else {
defaultHandler();
}
}
}
}
),
tabToOpenAsModal: {
screen: TabToOpenAsModalScreen
}
},
{
mode: 'modal',
headerMode: 'none'
}
);
If you nest your tab navigator within a stack navigator with a modal, you can open this when the tab bar button is pressed. Since the modal was opened and not the tab, when the modal is closed the app returns to the screen that was visible before the modal tab was pressed.
One way to make the tab bar go away is to hide the tabBar with visible: false:
const MyApp = TabNavigator({
Home: {
screen: MyHomeScreen,
},
TakePhoto: {
screen: PhotoPickerScreen,
navigationOptions: {
tabBar: {
visible: false,
},
},
},
});
However, that does not seem to trigger any transition to fullscreen, which I guess is desired?
Another option could be to wrap PhotoPickerScreen inside a new StackNavigator and set that navigator to mode='modal'.
You might have to trigger the navigation to that modal from onPress on the tabItem somehow (eg. navigation.navigate('TakePhoto').)
Note, I'm trying to wrap my head around how best to structure navigation myself, so …
Third option, implementing a StackNavigator as parent, then adding the MyApp TabNavigator as the first route inside of it, could be the most flexible solution. Then the TakePhoto screen would be on the same level as the TabNavigator, allowing you to route to it from wherever.
Interested to hear what you come up with!
I suggest two solution
First one is about hide it
For seconde one please read that: https://reactnavigation.org/docs/hiding-tabbar-in-screens
<Tab.Screen
name={Routes.CREATE_ANNOUNCEMENT_SCREEN}
// name={Routes.TEST_SCREEN}
options={{
.
.
.
tabBarVisible: false, <----- solution 1
tabBarButton: (props) => ( <----- or solution 2
<TouchableOpacity
{...props}
onPress={() => {
navigation.navigate(Routes.DETAILS_SCREEN);
}}
/>
),
}}
component={CreateAnnouncementScreen}
/>
Docs are patchy in some areas, but here it is:
export default class HomeScene extends Component {
static navigationOptions = {
title: 'foo',
header:{
visible: true
}
}
....
}
