Hide tabs on keyboard open

Question

I want to hide my tabs when the keyboard is open, and show the tabs again when the keyboard is closed.

I know that I can go just for "AdjustSpan", and thats it, but the problem is that if I do that, the keyboard also hides an input that I have for a chat, because its a footer.

Whats the best way to hide the tabs?

I already tried with [ngClass] in , I tried with Keyboard.disableScroll, and also in app.module.ts using the parameters scrollAssist and autoFocusAssist with false value...

Nothing seems to work.

Any idea of how should I hide the tabs??

Thank you in advance!!

You have to add an eventlistener for keyboard-interaction to add (or remove) some css class to the body-tag. In ionic1 the class "hide-on-keyboard-open" was added by default from the framework. In ionic2 you have to walk the "custom-implementation-path". So, here is what you are looking for:

1) Install keyboard-plugin and node_modules as described in ionic2 docs:

ionic plugin add ionic-plugin-keyboard
npm install --save @ionic-native/keyboard

https://ionicframework.com/docs/native/keyboard/

2) Add the plugin to your app.modules.ts

3) Add the desired eventlister withiin the device-ready event in your app.component.ts:

this.platform.ready().then(() => {

        // Okay, so the platform is ready and our plugins are available.
        // Here you can do any higher level native things you might need.
        this.statusBar.styleDefault();

        this.keyboard.onKeyboardShow().subscribe(() => {
            document.body.classList.add('keyboard-is-open');
        });

        this.keyboard.onKeyboardHide().subscribe(() => {
            document.body.classList.remove('keyboard-is-open');
        });
})

4) Add the class defintion to your app.scss with a additional class-attribute (hideElementOnKeyboardShown)

body.keyboard-is-open .hideElementOnKeyboardShown{
    display: none;        
}

5) Add the class to the desired element, eg an footer, div or sth else:

<ion-footer class="hideElementOnKeyboardShown">
    <button round ion-button (click)="onLogin()"  block>
        <ion-icon name="logo-facebook" padding></ion-icon>
            Login
    </button>
</ion-footer>

6) in this case, put the ion-footer tag within the content-tag, otherwise the calculated viewheight isnt correct when keyboard is shown.

have a nice day!

Answer 2

just add the following lines to your config.xml..

 <platform name="android">

<preference name="android- 
      manifest/application/activity/@android:windowSoftInputMode" 
   value="adjustPan" />

....
</platform>

What this does is modify the default value that Cordova writes to your AndroidManifest.xml to control the global keyboard input behaviour for your app.
