角度材质选项卡动画不起作用 [英] Angular material tab animation doesn't work

问题描述

我有角材料导航选项卡，如下面的示例所示.标签本身工作正常，导航也工作正常.我的问题是动画不起作用.当我单击一个选项卡时，我会在几秒钟内获得三倍大小的选项卡，而不是动画.我在 app.module.ts 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.没有它，除了动画，一切都正常.所以只需添加到您的样式

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";

如果您在向项目添加材料时遇到类似问题，只需阅读手册两遍，您可能会错过一些内容.https://material.angular.io/guide/getting-started

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
