如何在mat-收音机内设置mat-input的焦点

import { Component, ViewChild, ElementRef } from '@angular/core';
import { MatInput } from '@angular/material/input';

@Component({
  selector: 'app-your-component',
  templateUrl: './your-component.component.html',
  styleUrls: ['./your-component.component.css']
})
export class YourComponent {
  @ViewChild('inputElement') inputElement: ElementRef;
}

<mat-form-field>
  <input matInput id="inputElement">
</mat-form-field>

ngAfterViewInit() {
  this.inputElement.nativeElement.focus();
}
