Getting route param as null in angular 7

I am unable to retrive the route param as null. I am using angular7. Please find the code below

HeaderComponent ts file

    import {Router, ActivatedRoute} from '@angular/router';
    constructor(private httpService: HttpClient, private router: Router, private activatedRoute: ActivatedRoute) {
             this.getNewsSelectedFromRouteParam();
        }
    getNewsSelectedFromRouteParam() {
            alert();
            let id = this.activatedRoute.snapshot.paramMap.get('typeId');
            alert(id);
        }
getNewsByCountry(newsTypeSelected: any) {
        this.router.navigate(['/news',newsTypeSelected]);
        this.getNewsSelectedFromRouteParam();
    }

Header html

<div class=" dropdown-toggle" data-toggle="dropdown">
                XXX
            </div>
            <div class="dropdown-menu">
                <div *ngFor="let cr of country" class="dropdown-item"
                    (click)="getNewsByCountry(cr.value)" >{{cr.name}}</div>
            </div>

app routing ts file

 const routes: Routes = [
        { path: 'news/:typeId', component: XxxComponent },
    { path: '**', component: XxxComponent }
    ];

I am trying to get that Params in "HeaderComponent ts" where it should call from "XxxComponent". I added that route param code in XxxComponent ts file now working as expected. I am able to get the route params.
