In my react native project, I want bottom tabBar to be shown on screen, as you scroll upwards with your finger, say 200 offset y, the tabBar hides with animation, and when you scroll down, again, say 200 offset y, it shows the tabBar again.
I am using createBottomTabNavigator. I am able to show/hide bottom bar without animation.
I have tried

Below is my code
navigationOptions: ({ navigation }) => {
const params = navigation.state.params;
return {
tabBarVisible: params && params.tabBarVisible,
animationEnabled: true,
}
},
How can I animate the bottom bar as user scrolls the list?
Thanks in advance.
If you want a bottom navigation with animation, you can use the createMaterialTopTabNavigator and simply set the tabBarPosition.

Bottom navigation tabs don't hide without animation. Whenever I use the text input in react native bottom navigation tab is pushed up by the keyboard. That was somewhat solved by using:
screenOptions={{
tabBarHideOnKeyboard: true,
}}
However, even after trying that bottom tab is seen for a moment. Is there a way to not see that bottom tab or turn off that bottom tab appearing and disappearing animation? I'm using react-navigation bottom tabs.
If I open a modal (on iOS), and this modal navigates to another modal, I don't get a "right to left" navigation. I have a bottom to top navigation everytime the target is modal, but I just want this behavior on the first openned modal, then, the rest right to left.
How can I make this navigation? It feels weird openning twice from bottom to top.

Or you can use transitionConfig for each screen you want.
transitionConfig: () => ({
screenInterpolator: CardStackStyleInterpolator.forHorizontal,
}),
I am using react navigation library and I would like root stack view to be able to push some screens using right to left animation and some screens bottom to top. The main problem I have encountered is pan gesture for dismissing screens remains the same for all screens.
My routes:
const MODAL_ROUTES = [
SceneKeys.EditProfileNavigator,
SceneKeys.PicturePreview
]
const navigator = createStackNavigator(
{
[SceneKeys.Main]: { // MAIN TAB BAR SCREEN
screen: Main,
},
// Profile edit - comes from bottom, should not be dismissable by gestures
[SceneKeys.EditProfileNavigator]: {
screen: EditProfileNavigator,
navigationOptions: {
gesturesEnabled: false,
}
},
// Picture preview - comes from bottom, should be dismissible with gesture top to bottom
[SceneKeys.PicturePreview]: {
screen: PicturePreview,
},
// comes from right, should be dismissible by swiping from the left
[SceneKeys.Conversation]: {
screen: Conversation
}
},
{
headerMode: 'none',
transitionConfig: (transitionProps, prevTransitionProps) => {
const isModal = MODAL_ROUTES.some(
screenName =>
screenName === transitionProps.scene.route.routeName ||
(prevTransitionProps && screenName === prevTransitionProps.scene.route.routeName)
)
return StackViewTransitionConfigs.defaultTransitionConfig(
transitionProps,
prevTransitionProps,
isModal
)
}
},
)
Animations and transitions all work fine, however the main problem is that PicturePreview screen can be dismissed using left to right pan gesture - I want top to bottom pan gesture dismissal for this screen in particular.
Setting whole stack mode to modal makes Conversation screen transition from bottom, when I want right to left transition
Not the answer that I was looking for, but I found solution to my problem.
Basically i wrapped my navigator to another modal navigator.
My Routes now look like this:
> Modal Stack navigator
> Stack navigator
> Tab Bar
> Conversation
> Edit profile
> Picture preview
Honestly if anyone wants to suggest how to fix my problem in other ways - please do
I have tab based navigation in one of my react native component. I'm using React Navigation v1. React Navigation shows tab indicator only for the current active tab.
However, I want every tabs to show tab indicator (bottom border on tab) by default but with different colors of course. And when active, each tab will show slightly different shade of the color.
I have tried with React Navigation v1, v2, Native Base. Couldn't find a way around.
I want the tab bar exactly like this image.
In React Navigation, we have something like this :
TabNavigator(
{
Tab1: { screen: Tab1Component },
Tab2: { screen: Tab2Component }
},
{
tabBarComponent: TabBarTop,
tabBarPosition: 'top',
tabBarOptions: {
indicatorStyle: {
borderBottomColor: '#6495ed',
borderBottomWidth: 2
}
}
}
)
But this adds the style to the entire tabs. I want some ability to be applied on each tab basis. Same with Native Base's tabBarUnderlineStyle.
You should use this props in your tabBarOptions inside TabNavigatorConfig
activeTintColor - Label and icon color of the active tab.
activeBackgroundColor - Background color of the active tab.
inactiveTintColor - Label and icon color of the inactive tab.
inactiveBackgroundColor - Background color of the inactive tab.
I've created a ReactNative app that uses StackNavigator. Whenever the app navigates from one screen to another, it animates the navigation. Is there a way to remove the animation or customize it? StackNavigator also adds a title to each of my screen. Is there a way to remove the screen title? I tried setting the 'title' property of navigationOptions to an empty screen and the screen was rendered without a title. However, navigating from this screen to another one will cause an exception.
e.g. the "welcome" title in these sample screens
To remove the header from a stackNavigator screen, set headerMode in StackNavigatorConfig to none. So, your stackNavigator should look like so:
import HomeScreen from 'path/to/screen';
const stack = StackNavigator({
Home: {
screen: HomeScreen
}
}, {
headerMode: 'none' // <= here
});
There is an active proposal to allow the customization of animation in react navigation. You can follow this open issue
