角度材质标签动画不起作用 [英] Angular material tab animation doesn't work

问题描述

我有角度材料导航选项卡，如下面的示例所示。标签本身可以正常工作，导航也可以。我的问题是动画不起作用。当我单击一个标签时，而不是动画，我会在几秒钟内得到三倍尺寸的标签。我在app.module.ts中的导入中有 BrowserAnimationsModule 和 MatTabsModule 。可能是什么问题？如何修复动画？

I have angular material navigation tabs like in sample below. Tabs itself works fine and navigation works too. My issue is animation doesn't work. When I click a tab, instead of animation I get tab of triple size for couple of seconds. I have BrowserAnimationsModule and MatTabsModule in my imports in my app.module.ts. What might be the issue? How to fix animation?

<nav mat-tab-nav-bar>
  <a mat-tab-link [routerLink]="'/'" routerLinkActive #rla="routerLinkActive" [active]="rla.isActive">
    Home
  </a>
  <a mat-tab-link [routerLink]="'/projects'" routerLinkActive #rla="routerLinkActive" [active]="rla.isActive">
    Projects
  </a>
  <a mat-tab-link [routerLink]="'/about'" routerLinkActive #rla="routerLinkActive"   [active]="rla.isActive">
    About
  </a>
</nav>

推荐答案

动画不起作用，因为我忘记添加到 styles.css 默认主题中。没有动画，除了动画之外，其他所有东西都起作用。因此，只需添加您的样式

Animation didn't work because I forgot to add to styles.css default theme. Without it everything worked except animation. So just add to your styles

@import "~@angular/material/prebuilt-themes/indigo-pink.css";

如果您遇到类似的问题，则在向项目添加材料时只需阅读手册两次，您可能会错过一些东西。

If you encountered similar problems just read manual twice when adding material to your project, you might missed something. https://material.angular.io/guide/getting-started
