我必须单击以下菜单“文本视图”选项卡（mat-tab-link）两次以使路由器插座变为活动状态并在选项卡下划线。我知道这是因为单选按钮的documents.component.html 内容，它不会变为活动状态，除非我在“文本视图”选项卡上单击两次。然后“选项 4”按钮显示为活动状态，选项卡下划线。

文档-pane.component.html

<nav mat-tab-nav-bar aria-label="documentsTabs">
  <a class="navbar-brand" [routerLink]="['/customApp']">CustomApp</a>
  <a mat-tab-link 
    *ngFor="let link of navLinks"
    [routerLink]="link.path"
    routerLinkActive #rla="routerLinkActive"
    [active]="rla.isActive"
    skipLocationChange>
    {{link.label}}
  </a>
</nav>

<router-outlet></router-outlet>

文档-pane.component.ts

import { Component, OnInit } from '@angular/core';

文档.component.html

<div style='float: left; width: 75%;'>
  <mat-radio-group formControlName="testEntryOption">
    <mat-radio-button class="material-radio" value="opt1">Option 1</mat-radio-button>
    <mat-radio-button class="material-radio" value="opt2">Option 2</mat-radio-button>
    <mat-radio-button class="material-radio" value="opt3">Option 3</mat-radio-button>
    <mat-radio-button class="material-radio" value="opt4" [checked]="true">Option 4</mat-radio-button>
  </mat-radio-group>
</div>

<div style='float: left; width: 25%;'>
  <mat-button-toggle-group name="buttonSelection">
    <mat-button-toggle value="button1">Button 1</mat-button-toggle>
    <mat-button-toggle value="button2">Button 2</mat-button-toggle>
  </mat-button-toggle-group>
</div>
<div>
  documents works!
</div>

我尝试了其他几种代码实现，甚至是引导菜单栏，但都没有成功。非常感谢任何输入。我有哪些选择？
