Various methods have been proposed to manage the action of going back using the hardware button in Ionic. One common approach is shown below:
platform.ready().then(() => {
platform.registerBackButtonAction(() => {
However, I am interested in finding a solution to handle the back button that is displayed in the Navbar, as it does not seem to trigger when pressed on Android devices. Most solutions available only address handling hardware buttons specifically.
I successfully implemented this in Ionic 3 using the following code snippet.
import { Navbar } from 'ionic-angular';
export class CustomNavigation {
@ViewChild(Navbar) navBar: Navbar;
...
ionViewDidLoad() {
this.overrideBackButtonAction()
}
//Method to customize the back button behavior
overrideBackButtonAction(){
this.navBar.backButtonClick = () => {
//Add your custom logic here
this.navCtrl.pop()
}
}
If you want to customize the behavior of the back button in the Ionic navbar, you can do so by overriding the backButtonClick() function like demonstrated below:
backButtonClick() {
console.log('// dos omething')
}
ionViewDidEnter() {
this.navBar.backButtonClick = this.backButtonClick;
}
