I am making an English Reading app. When the user clicks on a word, they will see the translation of that word.
So how to make text is selected when the user clicks and holds for some time? I desire something likes document.onselectchange event in JavaScript for the web.
wrap the Text component with one of the available Touchable components i.e TouchableOpacity. You'll then have access to the onLongPress prop, where you can call a function which allows you to change the background color of the text to give the feel of being selected.

I have a Text component which I would like to make selectable. I provided the Text component the selectable prop, however it isn't working. I am pretty sure that it is because I have it nested in a ScrollView and my pressing it is only registering on the scrollview. Any way to get past this?
Can provide a code example if needed.
I am new to react-native. I want a toggle button with 2 text blocks. How this can be achieved with react native?.
The toggler should animate when clicking buy and sell texts respectively.
Following is the image reference for the design.
You can try this library.
This does not match the design exactly but it's a toggle with two text blocks. If you want something that looks exactly like your image I'm afraid you will have to build it yourself. You could use the mentioned library as a starting point.
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!
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.
Hi is there a way to make an multiline TextInput go fullscreen onFocus and return to its normal size after the user finished editting (for ex: when the user hits the android Back button).
I plan to allow user to type a long paragraph in my App, and I think it would improve the UX if I can make the multiline text go fullscreen when user typing.
I imagine a multiline TextInput like that would be a helpful for many other developers as well, it's shocking that I couldn't find a pre-built component like that.
I think the best way to achieve this is to put a TouchableOpacity with an onPress listener around the TextInput and have it navigate to another screen which has a full-screen text input and receives the onChange listener via params (there will be a warning with react-navigation-5 but in most cases you can safely ignore it).
