Keyboard

Keyboard module to control keyboard events.

Usage

The Keyboard module allows you to listen for native events and react to them, as well as make changes to the keyboard, like dismissing it.

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

class Example extends Component {
  componentDidMount() {
    this.keyboardDidShowListener = Keyboard.addListener(
      'keyboardDidShow',
      this._keyboardDidShow
    );
    this.keyboardDidHideListener = Keyboard.addListener(
      'keyboardDidHide',
      this._keyboardDidHide
    );
  }

  componentWillUnmount() {
    this.keyboardDidShowListener.remove();
    this.keyboardDidHideListener.remove();
  }

  _keyboardDidShow() {
    alert('Keyboard Shown');
  }

  _keyboardDidHide() {
    alert('Keyboard Hidden');
  }

  render() {
    return <TextInput onSubmitEditing={Keyboard.dismiss} />;
  }
}

Methods

addListener()

static addListener(eventName, callback)

The addListener function connects a JavaScript function to an identified native keyboard notification event.

This function then returns the reference to the listener.

@param {string} eventName The nativeEvent is the string that identifies the event you're listening for. This can be any of the following:

• keyboardWillShow
• keyboardDidShow
• keyboardWillHide
• keyboardDidHide
• keyboardWillChangeFrame
• keyboardDidChangeFrame

Note that if you set android:windowSoftInputMode to adjustResize or adjustNothing, only keyboardDidShow and keyboardDidHide events will be available on Android. keyboardWillShow as well as keyboardWillHide are generally not available on Android since there is no native corresponding event.

@param {function} callback function to be called when the event fires.

---

removeListener()

static removeListener(eventName, callback)

Removes a specific listener.

@param {string} eventName The nativeEvent is the string that identifies the event you're listening for. @param {function} callback function to be called when the event fires.

---

removeAllListeners()

static removeAllListeners(eventName)

Removes all listeners for a specific event type.

@param {string} eventType The native event string listeners are watching which will be removed.
