A foundational component for inputting text into the app via a keyboard. Props provide configurability for several features, such as auto-correction, auto-capitalization, placeholder text, and different keyboard types, such as a numeric keypad.

The simplest use case is to plop down a TextInput and subscribe to the onChangeText events to read the user input. There are also other events, such as onSubmitEditing and onFocus that can be subscribed to. A simple example:

import React, { Component } from 'react';
import { AppRegistry, TextInput } from 'react-native';

export default class UselessTextInput extends Component {
  constructor(props) {
    super(props);
    this.state = { text: 'Useless Placeholder' };
  }

  render() {
    return (
      <TextInput
        style={{height: 40, borderColor: 'gray', borderWidth: 1}}
        onChangeText={(text) => this.setState({text})}
        value={this.state.text}
      />
    );
  }
}

// skip this line if using Create React Native App
AppRegistry.registerComponent('AwesomeProject', () => UselessTextInput);

Two methods exposed via the native element are .focus() and .blur() that will focus or blur the TextInput programmatically.

Note that some props are only available with multiline={true/false}. Additionally, border styles that apply to only one side of the element (e.g., borderBottomColor, borderLeftWidth, etc.) will not be applied if multiline=false. To achieve the same effect, you can wrap your TextInput in a View:

import React, { Component } from 'react';
import { AppRegistry, View, TextInput } from 'react-native';

class UselessTextInput extends Component {
  render() {
    return (
      <TextInput
        {...this.props} // Inherit any props passed to it; e.g., multiline, numberOfLines below
        editable = {true}
        maxLength = {40}
      />
    );
  }
}

export default class UselessTextInputMultiline extends Component {
  constructor(props) {
    super(props);
    this.state = {
      text: 'Useless Multiline Placeholder',
    };
  }

  // If you type something in the text box that is a color, the background will change to that
  // color.
  render() {
    return (
     <View style={{
       backgroundColor: this.state.text,
       borderBottomColor: '#000000',
       borderBottomWidth: 1 }}
     >
       <UselessTextInput
         multiline = {true}
         numberOfLines = {4}
         onChangeText={(text) => this.setState({text})}
         value={this.state.text}
       />
     </View>
    );
  }
}

// skip these lines if using Create React Native App
AppRegistry.registerComponent(
 'AwesomeProject',
 () => UselessTextInputMultiline
);

TextInput has by default a border at the bottom of its view. This border has its padding set by the background image provided by the system, and it cannot be changed. Solutions to avoid this is to either not set height explicitly, case in which the system will take care of displaying the border in the correct position, or to not display the border by setting underlineColorAndroid to transparent.

Note that on Android performing text selection in input can change app's activity windowSoftInputMode param to adjustResize. This may cause issues with components that have position: 'absolute' while keyboard is active. To avoid this behavior either specify windowSoftInputMode in AndroidManifest.xml ( https://developer.android.com/guide/topics/manifest/activity-element.html ) or control this param programmatically with native code.

Reference

Props

allowFontScaling

Specifies whether fonts should scale to respect Text Size accessibility settings. The default is true.

autoCapitalize

Can tell TextInput to automatically capitalize certain characters. This property is not supported by some keyboard types such as name-phone-pad.

• characters: all characters.
• words: first letter of each word.
• sentences: first letter of each sentence (default).
• none: don't auto capitalize anything.

autoCompleteType

Specifies autocomplete hints for the system, so it can provide autofill. On Android, the system will always attempt to offer autofill by using heuristics to identify the type of content. To disable autocomplete, set autoCompleteType to off.

Possible values for autoCompleteType are:

• off
• username
• password
• email
• name
• tel
• street-address
• postal-code
• cc-number
• cc-csc
• cc-exp
• cc-exp-month
• cc-exp-year

autoCorrect

If false, disables auto-correct. The default value is true.

autoFocus

If true, focuses the input on componentDidMount. The default value is false.

blurOnSubmit

If true, the text field will blur when submitted. The default value is true for single-line fields and false for multiline fields. Note that for multiline fields, setting blurOnSubmit to true means that pressing return will blur the field and trigger the onSubmitEditing event instead of inserting a newline into the field.

caretHidden

If true, caret is hidden. The default value is false.

clearButtonMode

When the clear button should appear on the right side of the text view. This property is supported only for single-line TextInput component. The default value is never.

clearTextOnFocus

If true, clears the text field automatically when editing begins.

contextMenuHidden

If true, context menu is hidden. The default value is false.

dataDetectorTypes

Determines the types of data converted to clickable URLs in the text input. Only valid if multiline={true} and editable={false}. By default no data types are detected.

You can provide one type or an array of many types.

Possible values for dataDetectorTypes are:

• 'phoneNumber'
• 'link'
• 'address'
• 'calendarEvent'
• 'none'
• 'all'

defaultValue

Provides an initial value that will change when the user starts typing. Useful for simple use-cases where you do not want to deal with listening to events and updating the value prop to keep the controlled state in sync.

disableFullscreenUI

When false, if there is a small amount of space available around a text input (e.g. landscape orientation on a phone), the OS may choose to have the user edit the text inside of a full screen text input mode. When true, this feature is disabled and users will always edit the text directly inside of the text input. Defaults to false.

editable

If false, text is not editable. The default value is true.

enablesReturnKeyAutomatically

If true, the keyboard disables the return key when there is no text and automatically enables it when there is text. The default value is false.

importantForAutofill

Say the system whether the individual fields in your app should be included in a view structure for autofill purposes on Android API Level 26+, possible values are auto, no, noExcludeDescendants, yes, yesExcludeDescendants. The default value is auto.

• auto: Let the Android System use its heuristics to determine if the view is important for autofill.
• no: This view isn't important for autofill.
• noExcludeDescendants: This view and its children aren't important for autofill.
• yes: This view is important for autofill.
• yesExcludeDescendants: This view is important for autofill, but its children aren't important for autofill.

inlineImageLeft

If defined, the provided image resource will be rendered on the left. The image resource must be inside /android/app/src/main/res/drawable and referenced like

<TextInput
 inlineImageLeft='search_icon'
/>

inlineImagePadding

Padding between the inline image, if any, and the text input itself.

inputAccessoryViewID

An optional identifier which links a custom InputAccessoryView to this text input. The InputAccessoryView is rendered above the keyboard when this text input is focused.

keyboardAppearance

Determines the color of the keyboard.

keyboardType

Determines which keyboard to open, e.g.numeric.

See screenshots of all the types here.

The following values work across platforms:

• default
• number-pad
• decimal-pad
• numeric
• email-address
• phone-pad

iOS Only

The following values work on iOS only:

• ascii-capable
• numbers-and-punctuation
• url
• name-phone-pad
• twitter
• web-search

Android Only

The following values work on Android only:

• visible-password

maxFontSizeMultiplier

Specifies largest possible scale a font can reach when allowFontScaling is enabled. Possible values:

• null/undefined (default): inherit from the parent node or the global default (0)
• 0: no max, ignore parent/global default
• >= 1: sets the maxFontSizeMultiplier of this node to this value

maxLength

Limits the maximum number of characters that can be entered. Use this instead of implementing the logic in JS to avoid flicker.

multiline

If true, the text input can be multiple lines. The default value is false. It is important to note that this aligns the text to the top on iOS, and centers it on Android. Use with textAlignVertical set to top for the same behavior in both platforms.

numberOfLines

Sets the number of lines for a TextInput. Use it with multiline set to true to be able to fill the lines.

onBlur

Callback that is called when the text input is blurred.

onChange

Callback that is called when the text input's text changes. This will be called with { nativeEvent: { eventCount, target, text} }

onChangeText

Callback that is called when the text input's text changes. Changed text is passed as a single string argument to the callback handler.

onContentSizeChange

Callback that is called when the text input's content size changes. This will be called with { nativeEvent: { contentSize: { width, height } } }.

Only called for multiline text inputs.

onEndEditing

Callback that is called when text input ends.

onFocus

Callback that is called when the text input is focused. This is called with { nativeEvent: { target } }.

onKeyPress

Callback that is called when a key is pressed. This will be called with { nativeEvent: { key: keyValue } } where keyValue is 'Enter' or 'Backspace' for respective keys and the typed-in character otherwise including ' ' for space. Fires before onChange callbacks. Note: on Android only the inputs from soft keyboard are handled, not the hardware keyboard inputs.

onLayout

Invoked on mount and layout changes with { nativeEvent: {layout: {x, y, width, height}, target } }.

onScroll

Invoked on content scroll with { nativeEvent: { contentOffset: { x, y } } }. May also contain other properties from ScrollEvent but on Android contentSize is not provided for performance reasons.

onSelectionChange

Callback that is called when the text input selection is changed. This will be called with { nativeEvent: { selection: { start, end } } }. This prop requires multiline={true} to be set.

onSubmitEditing

Callback that is called when the text input's submit button is pressed with the argument {nativeEvent: {text, eventCount, target}}. Invalid if multiline={true} is specified.

placeholder

The string that will be rendered before text input has been entered.

placeholderTextColor

The text color of the placeholder string.

returnKeyLabel

Sets the return key to the label. Use it instead of returnKeyType.

returnKeyType

Determines how the return key should look. On Android you can also use returnKeyLabel.

Cross platform

The following values work across platforms:

• done
• go
• next
• search
• send

Android Only

The following values work on Android only:

• none
• previous

iOS Only

The following values work on iOS only:

• default
• emergency-call
• google
• join
• route
• yahoo

rejectResponderTermination

iOS Only

If true, allows TextInput to pass touch events to the parent component. This allows components such as SwipeableListView to be swipeable from the TextInput on iOS, as is the case on Android by default. If false, TextInput always asks to handle the input (except when disabled). The default value is true.

scrollEnabled

If false, scrolling of the text view will be disabled. The default value is true. Only works with multiline={true}.

secureTextEntry

If true, the text input obscures the text entered so that sensitive text like passwords stay secure. The default value is false. Does not work with multiline={true}.

selection

The start and end of the text input's selection. Set start and end to the same value to position the cursor.

selectionColor

The highlight and cursor color of the text input.

selectionState

An instance of DocumentSelectionState, this is some state that is responsible for maintaining selection information for a document.

Some functionality that can be performed with this instance is:

• blur()
• focus()
• update()

You can reference DocumentSelectionState in vendor/document/selection/DocumentSelectionState.js

selectTextOnFocus

If true, all text will automatically be selected on focus.

showSoftInputOnFocus

When false, it will prevent the soft keyboard from showing when the field is focused. The default value is true.

spellCheck

If false, disables spell-check style (i.e. red underlines). The default value is inherited from autoCorrect.

textContentType

Give the keyboard and the system information about the expected semantic meaning for the content that users enter.

For iOS 11+ you can set textContentType to username or password to enable autofill of login details from the device keychain.

For iOS 12+ newPassword can be used to indicate a new password input the user may want to save in the keychain, and oneTimeCode can be used to indicate that a field can be autofilled by a code arriving in an SMS.

To disable autofill, set textContentType to none.

Possible values for textContentType are:

• none
• URL
• addressCity
• addressCityAndState
• addressState
• countryName
• creditCardNumber
• emailAddress
• familyName
• fullStreetAddress
• givenName
• jobTitle
• location
• middleName
• name
• namePrefix
• nameSuffix
• nickname
• organizationName
• postalCode
• streetAddressLine1
• streetAddressLine2
• sublocality
• telephoneNumber
• username
• password
• newPassword
• oneTimeCode

style

Note that not all Text styles are supported, an incomplete list of what is not supported includes:

• borderLeftWidth
• borderTopWidth
• borderRightWidth
• borderBottomWidth
• borderTopLeftRadius
• borderTopRightRadius
• borderBottomRightRadius
• borderBottomLeftRadius

see Issue#7070 for more detail.

Styles

textBreakStrategy

Set text break strategy on Android API Level 23+, possible values are simple, highQuality, balanced The default value is simple.

underlineColorAndroid

The color of the TextInput underline.

value

The value to show for the text input. TextInput is a controlled component, which means the native value will be forced to match this value prop if provided. For most uses, this works great, but in some cases this may cause flickering - one common cause is preventing edits by keeping value the same. In addition to simply setting the same value, either set editable={false}, or set/update maxLength to prevent unwanted edits without flicker.

Methods

clear()

clear();

Removes all text from the TextInput.

isFocused()

isFocused();

Returns true if the input is currently focused; false otherwise.

Known issues

• react-native#19096: Doesn't support Android's onKeyPreIme.
• react-native#19366: Calling .focus() after closing Android's keyboard via back button doesn't bring keyboard up again.
