I have a view, in which there is a redux form field linked to a text input.
First of all, is there a way to show that keypad on initial rendering without the sliding in animation?
Second, on finished editing, is there a way to still keep the keypad up there?
I have tried to set blurOnSubmit to false in TextInput, it seems to stop me from losing the focus by clicking outside.
Lastly, there is also a button on that page which will start a request with the input value, on resolved, a modal will slide up from the bottom to show a success screen. This modal is implemented using react-navigation. The modal is a relatively small rectangle shape with the rest part transparent. So users can see the original page even when the success modal is up. In this case, is there a way to always show the keypad in the original screen even when the modal is up?

No. React Native doesn't support a way to disable the slide animation.

If the TextInput is being rendered inside a ScrollView, add keyboardShouldPersistTaps=handled. https://facebook.github.io/react-native/docs/scrollview#keyboardshouldpersisttaps. It will hold the focus.

I have a screen with WebView (react-native-webview) which has scrollable content. If user continues scrolling after reaching the end of WebView, I want to take user to a different screen with a swipe up animation. With WebView's onScroll function property, I am able to determine if the user has reached end of content or not. But I am not able to take user to a different screen with an animation effect.
Since WebView acts different for android and ios platform (you can continue scrolling even after reaching end of content on ios), I had to use PanGestureHandler to identify if the user is performing swipe up action after reaching end of web content. But when I manually try to navigate user to a different screen, I am unable to create swipe up effect similar to one in GIF below.
I am using react-navigation v5 in my app.
I have already tried using react-native-swiper. It does not work well in Android because it internally uses Scrollable and WebView stop scrolling inside a Scrollable component.
I am using custom HTML content here, so replacing WebView is not really a choice. Is there a way to utilize Stack Navigator to create such an effect?
Thank you.
So I have a react-native app which is using react-native-navigation.
Whenever I click a card in my app, it pushes me the card screen.
What I want to achieve is the following: when swiping down from that screen, as you swipe down the screen gets smaller and the other one is in the background, but I haven't found anything that can help me with that, any packages? Also, I'd have to pop the current screen to have the other one the background, but if I pop it, the current screen can't stay and get smaller as i swipe down.
So basically I need to animate a component pop.
If you haven't figured it out yet, you could show the card screen as an overlay or modal and add a swipe-down gesture to the Container component of the screen and when it reaches the bottom, you could dismissOverlay or dismissModal with no animation.
I have used text input in creating a search bar on the 'HomeScreen'. Whenever I click on the search bar, it takes me to the 'SearchScreen' where text input is focussed.
In both screens, I have placeholder "Search" in the text input. The problem I am facing is that the placeholder flickers whenever screens are changed. This happens all the time if/when text input is re-rendered.
I want the placeholder to remain static there for smooth transition between screens. Please let me know if you have any idea on how to erect it or if you have any suggested workaround.
Take a look at this library Fluid Transitions. This library helps to create smooth transitions between screens and shared components. Thus, you can go from screen A to screen B maintaining you search bar input intact or at least keep it with a smooth transition.
Another idea is... Do you really need to move to another screen when focusing the search bar? Is it possible if you just create an SearchList component that "shows/hides" a FlatList (for example), when the user focus the search bar, it will change to another screen when the user clicks on a specific result.
I am using react-native-router-flux and here's some observation, previously I was using .replace() for switching scenes, this time I used .push(), customizing it to not show any animation and now search does not flicker when popping the search screen, however, it does flicker on pushing search screen onto the stack, seems like the re-render is causing flickering (as pop does not trigger a render but push does).
It's best to avoid using the placeholder as for now until the problem is sorted in react-native itself.
I'm attempting to create a custom NavBar on a screen that renders a ScrollView. Inside the NavBar, there's a button, that when pressed, causes the NavBar to translate downwards, thereby giving the appearance that the NavBar is expanding (This is done using Animated.spring() with the useNativeDriver option). Everything is working great, except if the ScrollView is still scrolling at the time the button is tapped (ie: when "momentum" scroll is taking place). In this scenario, the onPress handler that kicks off the NavBar animation is invoked as expected, but calls to Animated.spring() do not cause any animation to take place. Is it possible to either have the NavBar "expansion" animation to occur during the scroll, or pause the scroll to allow animation to proceed?
Like it's explained in RN docs the animation type you using are stoped by gesture events like scrolling, better use Animated.event() with onScrollprops combined with an interpolation animation to animate you footer.
In a react-native form, when switching from one TextInput to the next one, the second grabs focus for an instant and then suddenly RN dismisses the keyboard.
I have onSubmitEditing coded to move to next input, but the user needs to click on enter in the keyboard, I can also override onEndEditing however that forces you to move to the next input and maybe you didn't touch that one.
I found out that the problem is related to having TextInputs within a ScrollView, focus between inputs in this component doesn't work as expected.
keyboardShouldPersistTaps={true} is deprecated so need to use keyboardShouldPersistTaps="always"
