Flatlist not working inside TouchableWithoutFeedback - react-native

I have a component that dismisses the keyboard. I then wrap my entire component with this one so whenever I tap outside of the TextInput the keyboard gets dismissed . But the problem is that in my other component I have a Flatlist and it does not scroll at all with TouchableWithoutFeedback. Any recommendations will be appreciated because I have not found a solution yet for hours! Thank you!
export const DismissKeyboard: React.FC<{
isKeyboardOpen?: boolean
style?: ViewStyle
}> = ({ children, style }) => (
<TouchableWithoutFeedback onPress={Keyboard.dismiss}>
<View style={style}>{children}</View>
</TouchableWithoutFeedback>
)
<DissmissKeyboard>
<FlatList
...flatlist data
/>
</DissmissKeyboard>

Wrap the FlatList renderItem component into a TouchableWithoutFeedback or a TouchableOpacity

How to implement a FlatList inside of a Pressable without scrolling getting disabled?

Basically, I want the FlatList to have a onPress functionality (to explain simply) as well as the default scrolling functionality. Right now, if I have a FlatList inside a Pressable, then I am not able to scroll through the FlatList.
I have also tried to put Pressable inside the FlatList's RenderItem component, but I have a lot of items I'll be displaying, so it's going to inefficient.
Instead of Pressable wrapping the FlatList, I learnt that we can use React Native's Gesture Responder System on a simple View to get the behavior that I require.
<View
onStartShouldSetResponder={() => true}
onResponderRelease={doSomethingFunction}
>
<FlatList
data={someData}
renderItem={renderItemComponent}
/>
</View>
Try touch handling on FlatList item parent container like below so the scrolling issue would never come again and you can easily handle the touch on each item separately
<FlatList
style={{...}}
data={[...]}
keyExtractor={(item, index) => index.toString()}
renderItem={({ item }) => (
<TouchableWithoutFeedback onPress={() => {...}}>
<View>
....
</View>
</TouchableWithoutFeedback>
)}
/>

React Native - Flat list scrolling is not working in Pan Responder

React Native, Using PanResponder View as a parent and having flatlist as a child of the view, without PanResponder, flatlist scrolling is working fine but with PanResponder, flatlist scrolling is not working.
I dont find proper solution, but workaround is wrap the flatlist items in TouchableOpacity , it will make flatlist scrollable.
If you don't like TouchableOpacity's opacity then you can set activeOpacity to 1.
Example:
<View {...this.gestureHandlers.panHandlers} style={styles.container}>
<FlatList
horizontal={true}
data={this.state.FlatlistData}
renderItem={({ item }) => {
return (
<TouchableOpacity activeOpacity={1} style={styles.itemsStyle}>
{/* Your core view here */}
</TouchableOpacity>
)
}}
/>
</View>

Is that possible to force keyboard gone immediately in React Native? [duplicate]

If I tap onto a textinput, I want to be able to tap somewhere else in order to dismiss the keyboard again (not the return key though). I haven't found the slightest piece of information concerning this in all the tutorials and blog posts that I read.
This basic example is still not working for me with react-native 0.4.2 in the Simulator. Couldn't try it on my iPhone yet.
<View style={styles.container}>
<Text style={styles.welcome}>
Welcome to React Native!
</Text>
<Text style={styles.instructions}>
To get started, edit index.ios.js
</Text>
<Text style={styles.instructions}>
Press Cmd+R to reload,{'\n'}
Cmd+D or shake for dev menu
</Text>
<TextInput
style={{height: 40, borderColor: 'gray', borderWidth: 1}}
onEndEditing={this.clearFocus}
/>
</View>
The problem with keyboard not dismissing gets more severe if you have keyboardType='numeric', as there is no way to dismiss it.
Replacing View with ScrollView is not a correct solution, as if you have multiple textInputs or buttons, tapping on them while the keyboard is up will only dismiss the keyboard.
Correct way is to encapsulate View with TouchableWithoutFeedback and calling Keyboard.dismiss()
EDIT: You can now use ScrollView with keyboardShouldPersistTaps='handled' to only dismiss the keyboard when the tap is not handled by the children (ie. tapping on other textInputs or buttons)
If you have
<View style={{flex: 1}}>
<TextInput keyboardType='numeric'/>
</View>
Change it to
<ScrollView contentContainerStyle={{flexGrow: 1}}
keyboardShouldPersistTaps='handled'
>
<TextInput keyboardType='numeric'/>
</ScrollView>
or
import {Keyboard} from 'react-native'
<TouchableWithoutFeedback onPress={Keyboard.dismiss} accessible={false}>
<View style={{flex: 1}}>
<TextInput keyboardType='numeric'/>
</View>
</TouchableWithoutFeedback>
EDIT: You can also create a Higher Order Component to dismiss the keyboard.
import React from 'react';
import { TouchableWithoutFeedback, Keyboard, View } from 'react-native';
const DismissKeyboardHOC = (Comp) => {
return ({ children, ...props }) => (
<TouchableWithoutFeedback onPress={Keyboard.dismiss} accessible={false}>
<Comp {...props}>
{children}
</Comp>
</TouchableWithoutFeedback>
);
};
const DismissKeyboardView = DismissKeyboardHOC(View)
Simply use it like this
...
render() {
<DismissKeyboardView>
<TextInput keyboardType='numeric'/>
</DismissKeyboardView>
}
NOTE: the accessible={false} is required to make the input form continue to be accessible through VoiceOver. Visually impaired people will thank you!
This just got updated and documented! No more hidden tricks.
import { Keyboard } from 'react-native'
// Hide that keyboard!
Keyboard.dismiss()
Github link
Use React Native's Keyboard.dismiss()
Updated Answer
React Native exposed the static dismiss() method on the Keyboard, so the updated method is:
import { Keyboard } from 'react-native';
Keyboard.dismiss()
Original Answer
Use React Native's dismissKeyboard Library.
I had a very similar problem and felt like I was the only one that didn't get it.
ScrollViews
If you have a ScrollView, or anything that inherits from it like a ListView, you can add a prop that will automatically dismiss the keyboard based on press or dragging events.
The prop is keyboardDismissMode and can have a value of none, interactive or on-drag. You can read more on that here.
Regular Views
If you have something other than a ScrollView and you'd like any presses to dismiss the keyboard, you can use a simple TouchableWithoutFeedback and have the onPress use React Native's utility library dismissKeyboard to dismiss the keyboard for you.
In your example, you could do something like this:
var DismissKeyboard = require('dismissKeyboard'); // Require React Native's utility library.
// Wrap your view with a TouchableWithoutFeedback component like so.
<View style={styles.container}>
<TouchableWithoutFeedback onPress={ () => { DismissKeyboard() } }>
<View>
<Text style={styles.welcome}>
Welcome to React Native!
</Text>
<Text style={styles.instructions}>
To get started, edit index.ios.js
</Text>
<Text style={styles.instructions}>
Press Cmd+R to reload,{'\n'}
Cmd+D or shake for dev menu
</Text>
<TextInput style={{height: 40, borderColor: 'gray', borderWidth: 1}} />
</View>
</TouchableWithoutFeedback>
</View>
Note: TouchableWithoutFeedback can only have a single child so you need to wrap everything below it in a single View as shown above.
use this for custom dismissal
var dismissKeyboard = require('dismissKeyboard');
var TestView = React.createClass({
render: function(){
return (
<TouchableWithoutFeedback
onPress={dismissKeyboard}>
<View />
</TouchableWithoutFeedback>
)
}
})
The simple answer is to use a ScrollView instead of View and set the scrollable property to false (might need to adjust some styling though).
This way, the keyboard gets dismissed the moment I tap somewhere else. This might be an issue with react-native, but tap events only seem to be handled with ScrollViews which leads to the described behaviour.
Edit: Thanks to jllodra. Please note that if you tap directly into another Textinput and then outside, the keyboard still won't hide.
You can import keyboard from react-native like below:
import { Keyboard } from 'react-native';
and in your code could be something like this:
render() {
return (
<TextInput
onSubmit={Keyboard.dismiss}
/>
);
}
static dismiss()
Dismisses the active keyboard and removes focus.
I'm brand new to React, and ran into the exact same issue while making a demo app. If you use the onStartShouldSetResponder prop (described here), you can grab touches on a plain old React.View. Curious to hear more experienced React-ers' thoughts on this strategy / if there's a better one, but this is what worked for me:
containerTouched(event) {
this.refs.textInput.blur();
return false;
}
render() {
<View onStartShouldSetResponder={this.containerTouched.bind(this)}>
<TextInput ref='textInput' />
</View>
}
2 things to note here. First, as discussed here, there's not yet a way to end editing of all subviews, so we have to refer to the TextInput directly to blur it. Second, the onStartShouldSetResponder is intercepted by other touchable controls on top of it. So clicking on a TouchableHighlight etc (including another TextInput) within the container view will not trigger the event. However, clicking on an Image within the container view will still dismiss the keyboard.
Use ScrollView instead of View and set the keyboardShouldPersistTaps attribute to false.
<ScrollView style={styles.container} keyboardShouldPersistTaps={false}>
<TextInput
placeholder="Post Title"
onChange={(event) => this.updateTitle(event.nativeEvent.text)}
style={styles.default}/>
</ScrollView>
Wrapping your components in a TouchableWithoutFeedback can cause some weird scroll behavior and other issues. I prefer to wrap my topmost app in a View with the onStartShouldSetResponder property filled in. This will allow me to handle all unhandled touches and then dismiss the keyboard. Importantly, since the handler function returns false the touch event is propagated up like normal.
handleUnhandledTouches(){
Keyboard.dismiss
return false;
}
render(){
<View style={{ flex: 1 }} onStartShouldSetResponder={this.handleUnhandledTouches}>
<MyApp>
</View>
}
The simplest way to do this
import {Keyboard} from 'react-native'
and then use the function Keyboard.dismiss()
That's all.
Here is a screenshot of my code so you can understand faster.
Now wrap the entire view with TouchableWithoutFeedback and onPress function is keyboard.dismiss()
Here is the example
In this way if user tap on anywhere of the screen excluding textInput field, keyboard will be dismissed.
There are a few ways,
if you control of event like onPress you can use:
import { Keyboard } from 'react-native'
onClickFunction = () => {
Keyboard.dismiss()
}
if you want to close the keyboard when the use scrolling:
<ScrollView keyboardDismissMode={'on-drag'}>
//content
</ScrollView>
More option is when the user clicks outside the keyboard:
<KeyboardAvoidingView behavior='padding' style={{ flex: 1}}>
//inputs and other content
</KeyboardAvoidingView>
If any one needs a working example of how to dismiss a multiline text input here ya go! Hope this helps some folks out there, the docs do not describe a way to dismiss a multiline input at all, at least there was no specific reference on how to do it. Still a noob to actually posting here on the stack, if anyone thinks this should be a reference to the actual post this snippet was written for let me know.
import React, { Component } from 'react'
import {
Keyboard,
TextInput,
TouchableOpacity,
View,
KeyboardAvoidingView,
} from 'react-native'
class App extends Component {
constructor(props) {
super(props)
this.state = {
behavior: 'position',
}
this._keyboardDismiss = this._keyboardDismiss.bind(this)
}
componentWillMount() {
this.keyboardDidHideListener = Keyboard.addListener('keyboardDidHide', this._keyboardDidHide);
}
componentWillUnmount() {
this.keyboardDidHideListener.remove()
}
_keyboardDidHide() {
Keyboard.dismiss()
}
render() {
return (
<KeyboardAvoidingView
style={{ flex: 1 }}
behavior={this.state.behavior}
>
<TouchableOpacity onPress={this._keyboardDidHide}>
<View>
<TextInput
style={{
color: '#000000',
paddingLeft: 15,
paddingTop: 10,
fontSize: 18,
}}
multiline={true}
textStyle={{ fontSize: '20', fontFamily: 'Montserrat-Medium' }}
placeholder="Share your Success..."
value={this.state.text}
underlineColorAndroid="transparent"
returnKeyType={'default'}
/>
</View>
</TouchableOpacity>
</KeyboardAvoidingView>
)
}
}
Updated usage of ScrollView for React Native 0.39
<ScrollView scrollEnabled={false} contentContainerStyle={{flex: 1}} />
Although, there is still a problem with two TextInput boxes. eg. A username and password form would now dismiss the keyboard when switching between inputs. Would love to get some suggestions to keep keyboard alive when switching between TextInputs while using a ScrollView.
const dismissKeyboard = require('dismissKeyboard');
dismissKeyboard(); //dismisses it
Approach No# 2;
Thanks to user #ricardo-stuven for pointing this out, there is another better way to dismiss the keyboard which you can see in the example in the react native docs.
Simple import Keyboard and call it's method dismiss()
I just tested this using the latest React Native version (0.4.2), and the keyboard is dismissed when you tap elsewhere.
And FYI: you can set a callback function to be executed when you dismiss the keyboard by assigning it to the "onEndEditing" prop.
If i'm not mistaken the latest version of React Native has solved this issue of being able to dismiss the keyboard by tapping out.
How about placing a touchable component around/beside the TextInput?
var INPUTREF = 'MyTextInput';
class TestKb extends Component {
constructor(props) {
super(props);
}
render() {
return (
<View style={{ flex: 1, flexDirection: 'column', backgroundColor: 'blue' }}>
<View>
<TextInput ref={'MyTextInput'}
style={{
height: 40,
borderWidth: 1,
backgroundColor: 'grey'
}} ></TextInput>
</View>
<TouchableWithoutFeedback onPress={() => this.refs[INPUTREF].blur()}>
<View
style={{
flex: 1,
flexDirection: 'column',
backgroundColor: 'green'
}}
/>
</TouchableWithoutFeedback>
</View>
)
}
}
Wrap your whole component with:
import { TouchableWithoutFeedback, Keyboard } from 'react-native'
<TouchableWithoutFeedback onPress={() => Keyboard.dismiss()}>
...
</TouchableWithoutFeedback>
Worked for me
Using KeyBoard API from react-native does the trick.
import { Keyboard } from 'react-native'
// Hide the keyboard whenever you want using !
Keyboard.dismiss()
Keyboard module is used to control keyboard events.
import { Keyboard } from 'react-native'
Add below code in render method.
render() {
return <TextInput onSubmitEditing={Keyboard.dismiss} />;
}
You can use -
Keyboard.dismiss()
static dismiss() Dismisses the active keyboard and removes focus as per react native documents.
https://facebook.github.io/react-native/docs/keyboard.html
Use
Keyboard.dismiss(0);
to hide the keyboard.
Using keyboardShouldPersistTaps in the ScrollView you can pass in "handled", which deals with the issues that people are saying comes with using the ScrollView. This is what the documentation says about using 'handled': the keyboard will not dismiss automatically when the tap was handled by a children, (or captured by an ancestor). Here is where it's referenced.
First import Keyboard
import { Keyboard } from 'react-native'
Then inside your TextInput you add Keyboard.dismiss to the onSubmitEditing prop. You should have something that looks like this:
render(){
return(
<View>
<TextInput
onSubmitEditing={Keyboard.dismiss}
/>
</View>
)
}
We can use keyboard and tochablewithoutfeedback from react-native
const DismissKeyboard = ({ children }) => (
<TouchableWithoutFeedback
onPress={() => Keyboard.dismiss()}
>
{children}
</TouchableWithoutFeedback>
);
And use it in this way:
const App = () => (
<DismissKeyboard>
<View style={styles.container}>
<TextInput
style={styles.input}
placeholder="username"
keyboardType="numeric"
/>
<TextInput
style={styles.input}
placeholder="password"
/>
</View>
</DismissKeyboard>
);
I also explained here with source code.
Use Keyboard.dismiss() to dismiss keyboard at any time.
Wrap the View component that is the parent of the TextInput in a Pressable component and then pass Keyboard. dismiss to the onPress prop. So, if the user taps anywhere outside the TextInput field, it will trigger Keyboard. dismiss, resulting in the TextInput field losing focus and the keyboard being hidden.
<Pressable onPress={Keyboard.dismiss}>
<View>
<TextInput
multiline={true}
onChangeText={onChangeText}
value={text}
placeholder={...}
/>
</View>
</Pressable>
in ScrollView use
keyboardShouldPersistTaps="handled"
This will do your job.
There are many ways you could handle this, the answers above don't include returnType as it was not included in react-native that time.
1: You can solve it by wrapping your components inside ScrollView, by default ScrollView closes the keyboard if we press somewhere. But incase you want to use ScrollView but disable this effect. you can use pointerEvent prop to scrollView
pointerEvents = 'none'.
2: If you want to close the keyboard on a button press, You can just use Keyboard from react-native
import { Keyboard } from 'react-native'
and inside onPress of that button, you can useKeyboard.dismiss()'.
3: You can also close the keyboard when you click the return key on the keyboard,
NOTE: if your keyboard type is numeric, you won't have a return key.
So, you can enable it by giving it a prop, returnKeyType to done.
or you could use onSubmitEditing={Keyboard.dismiss},It gets called whenever we press the return key. And if you want to dismiss the keyboard when losing focus, you can use onBlur prop, onBlur = {Keyboard.dismiss}
Keyboard.dismiss() will do it. But sometimes it may lose the focus and Keyboard will be unable to find the ref. The most consistent way to do is put a ref=_ref to the textInput, and do _ref.blur() when you need to dismiss, and _ref.focus() when you need to bring back the keyboard.
Here is my solution for Keyboard dismissing and scrolling to tapped TextInput (I am using ScrollView with keyboardDismissMode prop):
import React from 'react';
import {
Platform,
KeyboardAvoidingView,
ScrollView
} from 'react-native';
const DismissKeyboard = ({ children }) => {
const isAndroid = Platform.OS === 'android';
const behavior = isAndroid ? false : 'padding';
return (
<KeyboardAvoidingView
enabled
behavior={ behavior }
style={{ flex: 1}}
>
<ScrollView
keyboardShouldPersistTaps={'always'}
keyboardDismissMode={'on-drag'}
>
{ children }
</ScrollView>
</KeyboardAvoidingView>
);
};
export default DismissKeyboard;
usage:
render(){
return(
<DismissKeyboard>
<TextInput
style={{height: 40, borderColor: 'gray', borderWidth: 1}}
onChangeText={(text) => this.setState({text})}
value={this.state.text}
/>
</DismissKeyboard>
);
}

react native: style props on TouchableOpacity component

In react native docs(https://facebook.github.io/react-native/docs/touchableopacity), there is no explanation about style props. But I already know using style props on TouchableOpacity component is okay.
for example
<TouchableOpacity style={styles.button}>
...
</TouchableOpacity>
How is it possible?
I don't get you but TouchableOpacity can set props "activeOpacity" for changing the opacity when clicking to the button.

React Native Touchable is disabling ScrollView

I'm new to React Native, so am probably asking something very obvious, but please help.
I have a view wrapped in a touchable, so that the whole area responds to tapping. Then have a ScrollView nested inside the view. The overall structure is something like this:
<TouchableWithoutFeedback onPress={this.handlePress.bind(this)}>
<View>
<ScrollView>
<Text>Hello, here is a very long text that needs scrolling.</Text>
<ScrollView>
</View>
</TouchableWithoutFeedback>
When this compiles and runs, the tapping is detected, but the scroll view doesn't scroll at all. I made the above code short and simple, but each component has the proper styling and I can see everything rendering fine and the long text is cutoff at the bottom of the ScrollView. Please help.
Thank you!
This is what worked for me:
<TouchableWithoutFeedback onPress={...}>
<View>
<ScrollView>
<View onStartShouldSetResponder={() => true}>
// Scrollable content
</View>
</ScrollView>
</View>
</TouchableWithoutFeedback>
The onStartShouldSetResponder prop stops the touch event propagation towards the TouchableWithoutFeedback element.
I'm using this structure it's working for me:
<TouchableWithoutFeedback onPress={() => {}}>
{other content}
<View onStartShouldSetResponder={() => true}>
<ScrollView>
{scrollable content}
</ScrollView>
</View>
</TouchableWithoutFeedback>
You can have a scrollView or FlatList inside a TouchableWithoutFeedback. Tho you shouldn't but some times you have no other choice to go. Taking a good look at this questions and answer validates that.
close react native modal by clicking on overlay,
how to dismiss modal by tapping screen in react native.
For the Question, The only way you can make it work (atleast that i know of), or the simplest way is to add a TouchableOpacity around Text in your code like this,
<TouchableWithoutFeedback onPress={this.handlePress.bind(this)}>
<View>
<ScrollView>
<TouchableOpacity>
<Text>Hello, here is a very long text that needs scrolling.</Text>
</TouchableOpacity>
<ScrollView>
</View>
</TouchableWithoutFeedback>
Note: TouchableOpacity is a wrapper for making Views respond properly to touches so automatically you can style it the way you would have styled your View Component then set some of its special props to whatever you want e.g activeOpacity etc. Moreso you can use TouchableHighlight it works, but it receives one child element i.e you enclose all your component inside a parent one.
I'm using this structure it's working for me:
<TouchableOpacity>
{other content}
<ScrollView>
<TouchableOpacity activeOpacity={1}>
{scrollable content}
</TouchableOpacity>
</ScrollView>
I found that for my situation the other examples did not work as they disabled the ability to click or disabled the ability to scroll. I instead used:
<FlatList
data={[{key: text1 }, { key: text2 } ...]}
renderItem={({ item }) => (
<TouchableWithoutFeedback onPress={this.onPressContent}>
<Text style={styles.text}>{item.key}</Text>
</TouchableWithoutFeedback>
)}
/>
I happend to need to multiple chunks but you could use single element in the data array for one piece of text.
This let the press event to fire as well as let the text scroll.
Trying to use a ScrollView component inside a TouchableWithoutFeedback component can cause some unexpected behavior because the TouchableWithoutFeedback component is designed to capture user gestures and trigger an action, but the ScrollView component is designed to allow users to scroll through content.Here is what the official docs say
Do not use unless you have a very good reason. All elements that
respond to press should have a visual feedback when touched.
TouchableWithoutFeedback supports only one child. If you wish to have
several child components, wrap them in a View. Importantly,
TouchableWithoutFeedback works by cloning its child and applying
responder props to it. It is therefore required that any intermediary
components pass through those props to the underlying React Native
component.
Thats write , you cannot have a scroll view inside the TouchableWithoutFeedback, it the property of react native that it will disable it, you can instead have your scroll view outside the TouchableWithoutFeedback tab and add the other contents that you want upon the click inside a view tag.
You can also use the Touchable Highlights instead, if the TouchableWithoutFeedback does not works.
