It is necessary "cordova-plugin-ionic-keyboard" plugin installed.

• https://github.com/ionic-team/cordova-plugin-ionic-keyboard

Tested in versions:

Ionic: @^4

Keyboard Plugin: cordova-plugin-ionic-keyboard@^2.2.0

Android: 9

Installation

To install the library:

npm install ionic-keyboard-assist --save

Add the service to your app.module.ts as a provider and set scrollPadding and scrollAssist to false:

import { IonicKeyboardAssist } from 'ionic-keyboard-assist';

@NgModule({
  ...
  IonicModule.forRoot({
    scrollPadding: false,
    scrollAssist: false
  }),
  ...
  providers: [ IonicKeyboardAssist ],
  ...
})
export class AppModule { }

Set KeyboardResize plugin preference to false on config.xml (for iOS): Read more

<preference name="KeyboardResize" value="false" />

Then, import and inject into the app.component.ts constructor and start the service:

import { IonicKeyboardAssist } from 'ionic-keyboard-assist';

constructor(private keyboardAssist: IonicKeyboardAssist ) { 
  this.keyboardAssist.init();
}

Preferences

scrollPadding

Boolean (true by default)

Possible values

• true: Add a padding-bottom to the screen the same size as the keyboard.
• false: Does not change the screen padding.

(Depending on the device, the cordova-plugin-ionic-keyboard calculates the wrong height)

scrollAssist

Boolean (true by default)

Possible values

• true: Position the active/focused field in the center of the screen.
• false: Does not give assistance to scroll.

Set the configs

...
  this.keyboardAssist.init({scrollPadding: true, scrollAssist: true});
...
or
...
  this.keyboardAssist.setOptions({scrollPadding: true, scrollAssist: true});
