React Native External Keyboard

React Native library for enhanced external keyboard support.

  • ⚡️ The New Architecture is supported
  • ⚡️ Bridgeless

Note

React Native 0.80.0 includes a fix for TextInput focus on Android. TextInput: Can now focus TextInput with keyboard (e00028f6bb by @joevilches)

This means that there is no need to use the workaround with KeyboardExtendedInput, and it is recommended to use the default TextInput instead. Additionally, because of changes in TextInput, focusType="press" for KeyboardExtendedInput no longer works on Android.

New Release: Focus Lock and Focus Order

Improved keyboard focus control with features like focus order, ordered links, and focus lock.

Android iOS
Android Focus Order Example iOS Focus Order Example
More Information

Advanced focus order functionality for Android and iOS, plus focus lock!

It can be really challenging to manage focus in React Native, but fortunately, there are tools available to simplify the process.

Link Focus Order

Linking components could be the most logical way to define focus order. By using properties such as orderId and orderBackward, orderForward, orderLeft, orderRight, orderUp, and orderDown, you can customize the focus order according to your needs.

<View>
  <Pressable
    onPress={onPress}
    orderId="0_0"
    orderForward="0_2"
  >
    <Text>1</Text>
  </Pressable>
  <Pressable
    onPress={onPress}
    orderId="0_2"
    orderBackward="0_1"
  >
    <Text>3</Text>
  </Pressable>
  <Pressable
    onPress={onPress}
    orderId="0_1"
    orderForward="0_2"
    orderBackward="0_0"
  >
    <Text>2</Text>
  </Pressable>
</View>

You can find more examples here: Focus Link Order, DPad Order

Props Description Type
orderId? A unique ID used for link target identification. string
orderBackward? ID of the target for backward navigation with "Tab + Shift". string
orderForward? ID of the target for forward navigation with "Tab". string
orderLeft? ID of the target for navigation to the left. string
orderRight? ID of the target for navigation to the right. string
orderUp? ID of the target for navigation upward. string
orderDown? ID of the target for navigation downward. string

Indexes Focus Order

Linking is one of the best ways to set up focus order. However, there may be cases where you need to define the order of multiple elements, such as groups. As an alternative solution, you can use Indexes.

<KeyboardOrderFocusGroup>
  <View>
    <Pressable
      onPress={onPress}
      orderIndex={0}
    >
      <Text>First</Text>
    </Pressable>
    <Pressable
      onPress={onPress}
      orderIndex={2}
    >
      <Text>Third</Text>
    </Pressable>
    <Pressable
      onPress={onPress}
      orderIndex={1}
    >
      <Text>Second</Text>
    </Pressable>
  </View>
</KeyboardOrderFocusGroup>

Indexing requres orderGroup param for proper order set, you can use KeyboardOrderFocusGroup or provide orderGroup to the component.

 <Pressable
      orderGroup="main"
      onPress={onPress}
      orderIndex={2}
    >
      <Text>Back</Text>
  </Pressable>
Props Description Type
orderGroup? The name of the group containing ordered elements. string
orderIndex? The order index of the element within the group. number

You can find more examples here: Focus Order via indexes

Focus Lock

Finally, you can lock focus to specific directions.

 <Pressable
  lockFocus={['down', 'right']}
>
  <Text>Lock Example</Text>
</Pressable>
Props Description Type
lockFocus? An array of directions to lock focus. Array of 'left'

[!NOTE]
first and last are specific to iOS. When focus is blocked for forward and backward on iOS, it checks for the last and first elements to focus.

iOS Android

Features

  • Keyboard focus management and autofocus capabilities.
  • Key press event handling.
  • Focus management for TextInput and Pressable components.
  • Customization of the Halo Effect and tintColor for iOS.
  • Keyboard focus order.

Installation

npm install react-native-external-keyboard

iOS:

cd ios && pod install && cd ..

Usage

withKeyboardFocus - For Pressable, Touchable, and more

The withKeyboardFocus HOC is a helper for integrating keyboard focus functionality. It significantly simplifies integration by wrapping the provided component in KeyboardFocusView and extending it with additional features, such as focus and blur events.

const KeybardedPressable = withKeyboardFocus(Pressable);
const KeybardedTouchable = withKeyboardFocus(TouchableOpacity);
const KeybardedButton = withKeyboardFocus(Button);

...

<TouchableOpacity
  ref={ref}
  onPress={...}
  onLongPress={...}
  onFocus={...}
  onBlur={...}
  style={styles.pressable}
  containerStyle={styles.pressableContainer}
  autoFocus
>
  <Text>TouchableOpacity</Text>
</TouchableOpacity>

After wrapping a Pressable or Touchable with withKeyboardFocus, you will be able to handle focus and blur events, control the tint color, apply focus and container focus styles, focus the component using a ref, or configure autoFocus.

Props Description Type

Note

You may discover that long press on spacebar does not trigger a long press event on iOS. This is because iOS use a Full Keyboard Access system that provides commands for interacting with the system. Rather than holding down the spacebar, you can use Tab+M (the default action for opening the context menu). You can change Commands in: Full Keyboard Access -> Commands

Keyboard

Keyboard module to support soft keyboard dismissal.

import { Keyboard } from 'react-native-external-keyboard';

...
  Keyboard.dismiss();
...

This is needed for hiding the soft keyboard using a hardware keyboard. Additionally, the soft keyboard can be hidden from the settings or by pressing Alt + K.

Focus order features

Link Focus Order

Linking components could be the most logical way to define focus order. By using properties such as orderId and orderBackward, orderForward, orderLeft, orderRight, orderUp, and orderDown, you can customize the focus order according to your needs.

<View>
  <Pressable
    onPress={onPress}
    orderId="0_0"
    orderForward="0_2"
  >
    <Text>1</Text>
  </Pressable>
  <Pressable
    onPress={onPress}
    orderId="0_2"
    orderBackward="0_1"
  >
    <Text>3</Text>
  </Pressable>
  <Pressable
    onPress={onPress}
    orderId="0_1"
    orderForward="0_2"
    orderBackward="0_0"
  >
    <Text>2</Text>
  </Pressable>
</View>

You can find more examples here: Focus Link Order, DPad Order

Props Description Type
orderId? A unique ID used for link target identification. string
orderBackward? ID of the target for backward navigation with "Tab + Shift". string
orderForward? ID of the target for forward navigation with "Tab". string
orderLeft? ID of the target for navigation to the left. string
orderRight? ID of the target for navigation to the right. string
orderUp? ID of the target for navigation upward. string
orderDown? ID of the target for navigation downward. string

Indexes Focus Order

Linking is one of the best ways to set up focus order. However, there may be cases where you need to define the order of multiple elements, such as groups. As an alternative solution, you can use Indexes.

<KeyboardOrderFocusGroup>
  <View>
    <Pressable
      onPress={onPress}
      orderIndex={0}
    >
      <Text>First</Text>
    </Pressable>
    <Pressable
      onPress={onPress}
      orderIndex={2}
    >
      <Text>Third</Text>
    </Pressable>
    <Pressable
      onPress={onPress}
      orderIndex={1}
    >
      <Text>Second</Text>
    </Pressable>
  </View>
</KeyboardOrderFocusGroup>

Indexing requres orderGroup param for proper order set, you can use KeyboardOrderFocusGroup or provide orderGroup to the component.

 <Pressable
      orderGroup="main"
      onPress={onPress}
      orderIndex={2}
    >
      <Text>Back</Text>
  </Pressable>
Props Description Type
orderGroup? The name of the group containing ordered elements. string
orderIndex? The order index of the element within the group. number

You can find more examples here: Focus Order via indexes

Focus Lock

Finally, you can lock focus to specific directions.

 <Pressable
  lockFocus={['down', 'right']}
>
  <Text>Lock Example</Text>
</Pressable>
Props Description Type
lockFocus? An array of directions to lock focus. Array of 'left' | 'right' | 'up' | 'down' | 'forward' | 'backward' | 'first' | 'last'

Note

first and last are specific to iOS. When focus is blocked for forward and backward on iOS, it checks for the last and first elements to focus.

Migration 0.3.x to 0.4.0

Module (A11yModule, KeyboardExtendedModule)

Functions in the A11yModule (KeyboardExtendedModule) have been deprecated. They appeared appropriate at the time, but with the new architecture and to improve usability, they have been replaced with ref actions.

Previous:

import { KeyboardExtendedModule } from 'react-native-external-keyboard';

KeyboardExtendedModule.setKeyboardFocus(ref); //or A11yModule.setKeyboardFocus(ref);

Updated:

import { KeyboardExtendedPressable, type KeyboardFocus } from 'react-native-external-keyboard';
...

const ref = useRef<KeyboardFocus>(null);

...

const onPressForFocus = () => {
  ref.current.focus()
}

<TouchableOpacity
  ref={ref}
>
  <Text>TouchableOpacity</Text>
</TouchableOpacity>

The specific method for iOS, setPreferredKeyboardFocus, has not been added so far because we now have the new feature autoFocus, which does not fit well with the new API and its approach. It is better to use autoFocus for focusing views on both Android and iOS.

If you truly need this method, please create a new issue, and we will consider how to return it.

Pressable

Pressable changes

Unfortunately, the previous version of Pressable had many issues. For iOS, we cloned the entire Pressable component from React Native's source code, while for Android, we simply wrapped the component.

This led to two main problems:

  1. Difficulty in updating Pressable for iOS.
  2. Challenges in controlling styles.

For these reasons, we replaced Pressable with withKeyboardFocus(Pressable), as it was the only viable path forward to introduce new features.

Component aliases

It is believed that good naming can simplify usage and development. Based on this principle and for compatibility with 0.2.x, aliases were added. You can still use the old naming convention, and it will be maintained in future releases.

The map of aliases is provided below:
A11yModule -> KeyboardExtendedModule
Pressable -> KeyboardExtendedPressable
KeyboardFocusView -> KeyboardExtendedView
ExternalKeyboardView -> KeyboardExtendedBaseView

API

ToDo

export type OnKeyPress = NativeSyntheticEvent<{
  keyCode: number;
  unicode: number;
  unicodeChar: string;
  isLongPress: boolean;
  isAltPressed: boolean;
  isShiftPressed: boolean;
  isCtrlPressed: boolean;
  isCapsLockOn: boolean;
  hasNoModifiers: boolean;
}>;

Roadmap

  • Refactor and Performance optimization
  • Update focusGroupIdentifier and implement KeyboardNavigationCluster functionality
  • Update onPress and onLongPress for withKeyboardFocus
  • Add functionality to control keyboard focus order.
  • Verify and update focusable and disabled states for iOS and Android.
  • Update Readme.md.
  • Create the documentation.
