@capacitor/keyboard

キーボードAPIは、キーボードの表示・非表示の制御、およびキーボードの表示・非表示時のイベントトラッキングを行います。

Install

npm install @capacitor/keyboard
npx cap sync

Example

import { Keyboard } from '@capacitor/keyboard';

Keyboard.addListener('keyboardWillShow', info => {
console.log('keyboard will show with height:', info.keyboardHeight);
});

Keyboard.addListener('keyboardDidShow', info => {
console.log('keyboard did show with height:', info.keyboardHeight);
});

Keyboard.addListener('keyboardWillHide', () => {
console.log('keyboard will hide');
});

Keyboard.addListener('keyboardDidHide', () => {
console.log('keyboard did hide');
});

Configuration

On iOS, the keyboard can be configured with the following options:

PropTypeDescriptionDefaultSince
resizeKeyboardResizeConfigure the way the app is resized when the Keyboard appears. Only available on iOS.native1.0.0
styleKeyboardStyleOverride the keyboard style if your app doesn't support dark/light theme changes. If not set, the keyboard style will depend on the device appearance. Only available on iOS.1.0.0
resizeOnFullScreenbooleanThere is an Android bug that prevents the keyboard from resizing the WebView when the app is in full screen (i.e. if StatusBar plugin is used to overlay the status bar). This setting, if set to true, add a workaround that resizes the WebView even when the app is in full screen. Only available for Android1.1.0

Examples

In capacitor.config.json:

{
"plugins": {
"Keyboard": {
"resize": "body",
"style": "DARK",
"resizeOnFullScreen": true
}
}
}

In capacitor.config.ts:

/// <reference types="@capacitor/keyboard" />

import { CapacitorConfig } from '@capacitor/cli';
import { KeyboardResize, KeyboardStyle } from '@capacitor/keyboard';

const config: CapacitorConfig = {
plugins: {
Keyboard: {
resize: KeyboardResize.Body,
style: KeyboardStyle.Dark,
resizeOnFullScreen: true,
},
},
};

export default config;
