Hide keyboard in react-native

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 correct answer should be that from Eric Kim below. The ScrollView answer (set scrollable to false) isn't ideal, if you have multiple text inputs it doesn't let you hop from text input to text input without the keyboard being dismissed.
For those who want a solution for the entire app see @Scottmas's answer below.(link: stackoverflow.com/a/49825223/1138273)
keyboard.dismiss() is what you are looking for.

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 is great, the only comment I have is that you could have used the official Keyboard api in RN, and called Keyboard.dismiss() instead of calling some RN internal utility dismissKeyboard(). But both work fine currently.
@PavleLekic Sorry for the delay, I updated the answer along with the HOC method
This works great. I had to change the syntax a little for the definition of the arrow function, to remove an unexpected token error in RN: const DismissKeyboardHOC = (Comp) => {
I can't get onPress for TouchableWithoutFeedback to fire no matter what I try
This solution works, but please keep in mind that you can not use swipe gestures in children of a Touchable component.

This just got updated and documented! No more hidden tricks.

import { Keyboard } from 'react-native'

// Hide that keyboard!
Keyboard.dismiss()

Thanks for adding this. I hope your answer bubbles up to the top. I almost missed it and used an outdated solution.
Pinging @MrMuetze to change this as the correct answer
This shouldn't be the selected as the best answer. The question asks how to dismiss the keyboard when tapping outside of it. This answer simply provides an API for doing so, whilst the actual best answer provides a workable implementation.
you can use the next library : KeyboardAwareScrollView
@jehna1 this is not the correct answer according to the question

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.

i have a keyboard that is hanging around since i did a reload while focused on an input field. in this case Keyboard.dismiss() does nothing since its implementation is dependent on being focused on an input, which I no longer am.
@pstanton What did you have to do to dismiss the keyboard, then?
There was no way I could find, so I force closed!

David Schumann

use this for custom dismissal

var dismissKeyboard = require('dismissKeyboard');

var TestView = React.createClass({
    render: function(){
        return (
            <TouchableWithoutFeedback 
                onPress={dismissKeyboard}>
                <View />
            </TouchableWithoutFeedback>
        )
    }
})

It's not documented, but the samples in react-native github repo does use it few times.
Interesting, for those curious where this comes from, it's a Utility library in React Native. Here's the source: github.com/facebook/react-native/blob/master/Libraries/…
For some reason it didn't work, when I tried with react-native-search-bar
This is the exact equivalent of Keyboard.dismiss, which is preferable since is documented. github.com/facebook/react-native/blob/…

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.


It works with scrollview but still there are some cases i'm experiencing where I can click button to change the view using navigator and keyboard still sticks at the bottom and have to manually click return key to close it :(
Keyboard hides when you tap outside the TextInput, but if (instead of tapping outside) you tap into another TextInput, and finally tap outside, the keyboard does not hide. Tested on 0.6.0.
I'm seeing different behavior now. Tapping outside the TextInput hides the keyboard, even if I tap directly onto another TextInput--which is a problem because you have to tap twice on another TextInput to be able to type into it! Sigh. (with RN 0.19)
You can set scrollable to true and use keyboardShouldPersistTaps={'handled'} and keyboardDismissMode={'on-drag'} to achieve the same effect
only scrollview worked for me I don't know why,the accepted answer when i input a number keyboard dismisses

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 did not need static dismiss(). I just added Keyboard.dismiss() to my onSubmit method (where onSubmitEditing={() => {this.onSubmit()}})

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.


It definitely works. But as you said, Im curious as well if this is the right way. Hope they solve it soon (github.com/facebook/react-native/issues/113 )
Great this worked for me. My scroll view was not working with the touchable methods! Thanks!

David Schumann

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>

According to the documentation, the keyboardShouldPersistTaps attribute defaults to false when using a ScrollView. I just updated my react-native to the latest version and the problem with switching to a second TextInput still persists. The keyboard then is not dismissible. Have you found a solution for this specific problem?
The docs were incorrect, but have now been updated, see this PR: github.com/facebook/react-native/issues/2150
What does keyboardShouldPersistTaps do? Why is it relevant here? Thanks
Warning: 'keyboardShouldPersistTaps={false}' is deprecated. Use 'keyboardShouldPersistTaps="never"' instead

Karthikeyan

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>
  }

Thanks for your answer @Scottmas. I ended up using it instead of TouchableWithoutFeedback, because of your "weird scroll behavior and other issues" comment. But if I wasn't blindly trusting your words, can you elaborate on your comment? :)

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.

https://i.stack.imgur.com/3juyl.png

Now wrap the entire view with TouchableWithoutFeedback and onPress function is keyboard.dismiss()

https://i.stack.imgur.com/ZWS5g.png

In this way if user tap on anywhere of the screen excluding textInput field, keyboard will be dismissed.

Idan

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>

Guys, the question is still actual but question is 4 years old(end of 2019 now). RN now is soo simple and easy to use. We have to review all abilities with help of we can achieve solution for this question. Let upvote this comment!

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.


It appears that 0.40 updates keyboardShouldPersistTaps from a boolean to an enum with a possible value of 'handled` which is suppose to fix this.

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()


This is the exact equivalent of Keyboard.dismiss, which is preferable since is documented. github.com/facebook/react-native/blob/…
At the time I gave this answer, this was not documented. Thanks for mentioning it. I'll update my answer.

Jonathan Huang

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.


I was debugging the "onEndEditing" callback, but it never triggered before; I'm going to look into this with the newer version of react native, thanks for your suggestion
c
christopherdro

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.


Would you be able to point out which part of their code/doc does that? I'm running into the same issue, and I really appreciate it pointing me the direction :)
Confirmed that this is still an issue as of RN 0.19 (the latest).
Still an issue with RN 0.28

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>

Keyboard module is used to control keyboard events.

import { Keyboard } from 'react-native'

Add below code in render method. render() { return ; }

You can use -

Keyboard.dismiss()

static dismiss() Dismisses the active keyboard and removes focus as per react native documents.


B
Baum mit Augen

https://facebook.github.io/react-native/docs/keyboard.html

Use

Keyboard.dismiss(0);

to hide the keyboard.


A
Andrew

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>
  )  
}

More context would be nice.

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.


S
Samuel

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.


This worked for me! (however I had to add it inside my 3rd party library react-native-keyboard-aware-scroll-view).
c
clemens

in ScrollView use

keyboardShouldPersistTaps="handled" 

This will do your job.


What to do if I want to restrict keyboard (don't want to close ) keyboard on an event ?
S
Sarmad Shah

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}


B
Bruce Lin

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.


A
Artem Shevtsov

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>
   );
}

Cyrus Zei

use this package react-native-keyboard-aware-scroll-view

use that component as your root component

since this package react-native-keyboard-aware-scroll-view also have an scrollView you need to add this to it:

<KeyboardAwareScrollView keyboardShouldPersistTaps="handled"> <ScrollView keyboardShouldPersistTaps="handled"></ScrollView> </KeyboardAwareScrollView>
