What is the difference between TextInput import from "react-native" and "react-native-gesture-handler"?
I too was wondering abou this, but from looking at the source, we can see that the gesture handler version is just a wrapper around the base TextInput. export const TextInput = createNativeWrapper<RNTextInputProps>(RNTextInput);
And online they explain that createNativeWrapper as
"Creates provided component with NativeViewGestureHandler, allowing it to be part of RNGH's gesture system."
So I think if you use the wrapped one, it will give you access to all sorts of gestures, like pinching, panning, long press etc that the base input doesn't have

I am working on a react native android app that needs a search bar. I am using the SearchBar from react-native-paper, and I checked their documentation and couldn't find any sort of way to find if the user pressed the little search button on their keyboard.
Not sure if there is an official name for this input or the button itself as I am unfamiliar with mobile app development, but here is an screenshot from the app in case it is unclear. I am referring to the search button on the keyboard itself, which is in this case blue.
From some digging I found out that TextInputs in react native have an onSubmitEditing={} that triggers whatever return key action you want.
Essentially I was wondering if there was an equivalent prop for the SearchBar in react-native-paper.
If you take a look at the implementation of react-native-paper SearchBar https://github.com/callstack/react-native-paper/blob/master/src/components/Searchbar.tsx it looks like you can pass a onSubmitEditing prop to it and, as react-native-paper uses a TextInput, that input will receive that prop
Ok so it seems that as tintef pointed out, you can just pass onSubmitEditing to the SearchBar since it uses a TextInput. I just tested this and it works perfectly!
Button in react-native has too much limit, So I used TouchableOpacity (with many decorations). But The button made with TouchableOpacity has an delay issue. I also felt it has delay to change screens when it clicked.
So I started to find an replacement, but I couldn't find it. There are Styled components, but I don't know it's performance.
Is Styled components's performance is better than TouchableOpacity, or There is another thing I can use for replacement of TouchableOpacity?
Try see this. it is about my issue.
You can create View component with onStartShouldSetResponder={()=> ... } and do with it everything you want. Especially it very usefull with hitslop.
I'm using react-native-elements Searchbar and want the placeholder on the right, and the text entry on the left.
It appears that you can only use text align to determine where to type, so I attempted to use a state to make the text on the left, placholder on the right. But this solution doesn't work either.
Any ideas?
React Native Elements supports styles similar to the TextInput along with their own props.
Since there is no prop to style the placeholder in react-native's textinputas well assearchbar`, therefore it cannot be done just with the styles.
However I can suggest you to make a separate instance of react-native-element SearchBar and pass your CustomTextInput component that contains the placeholder styles as mentioned in this post
I am trying to implement a custom navigator based on the TabRouter with React Navigation with custom complex animations and behavior, more or less in the fashion of a swipeable CoverFlow.
There are examples out there of how to do that using a StackRouter, but none of them work when changing to a TabRouter.
So far, I have understood that to get a navigator like the TabNavigator I would need a function like:
(routeConfigs, config = {}) => (
createNavigationContainer(
createNavigator(TabRouter(routeConfigs, config))(MyNavigationView)
)
);
with how to implement MyNavigationView being my main interrogation.
The docs are extremely superficial on each component of a navigator, keeping the description to a single sentence most of the time. So, what is precisely, and what is the role of:
a router
a navigation view
the Transitioner (should I use one ?)
Should I (and how) render all the scenes in my _renderScene function ?
How do I hide the scenes not displayed at the moment ?
I think I should use a PanResponder from inside the MyNavigationView to handle the swipe gesture. Should I (and, if yes, how to) update the router's state when the user swiped to a new scene ?
Also, I do not want to use the AnimatedTabView from react-native-tab-view that the TabNavigator is using internally as it doesn't work for me on iOS (conflict between ScrollView and PanResponder which likely won't be fixed for a while)
That is a lot of questions, but I am a little bit lost. I have been looking a lot at the sources of React Navigation, but they still leave me confused.
Even a partial answer would help.
I think this can help: https://github.com/react-navigation/react-navigation/blob/master/examples/NavigationPlayground/js/CustomTabs.js
So maybe you can update your function like this?
createNavigationContainer(
createNavigator(MyNavigationView, TabRouter(routeConfigs, config), {})
)
I'm using React Native 0.14.0 to develop an Android application. Currently I'm using the ToolbarAndroid component to add a toolbar on top of my scene, but it is not kept between scenes. I found that the Navigator has a navigationBar property, which can be set to a Navigator.NavigationBar component, which should include an object dealing with the title and left and right buttons of the navigation bar. See the official example to understand what I mean. As there is little documentation on this part, I have to rely on the example to set the navigationBar properly.
This Navigator.NavigationBar is not as powerful as the ToolbarAndroid, as itdoesn't automatically have space for the logo, for example.
Is there any way to use ToolbarAndroid with the navigationBar property of the Navigator?
Not really. The closest you could probably get is to wrap the ToolbarAndroid in a component and map the navigator left, right methods to the onIconClicked functions. But that defeats the purpose as you are probably most interested in the ToolbarAndroid's UI.
You need to pass a component that will behave something like the Navigator.NavigationBar. If you can drop in a component that will play nice and provide some of the expected props then it'll work.
