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 {
componentWillMount () {
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

Methods
addListener()
Keyboard.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.

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()
Keyboard.removeListener(eventName, callback)

@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.
