html - Angular 4 Material - mat-button 样式未应用于 mat-dialog 组件

Question

我想创建一个带有默认样式 mat-button 的 mat-dialog 来关闭对话框。除了按钮缺少 Angular Material 应用的 Material Design 风格外，一切正常。

如何让样式显示出来？据我所知，我已经按要求导入了所有模块，并且 properly set up each part of Angular Material including the themes .

my-dialog.component.ts:

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

@Component({
  selector: 'app-my-dialog',
  templateUrl: './my-dialog.component.html',
  styleUrls: ['./my-dialog.component.css']
})
export class MyDialogComponent implements OnInit {

  constructor() { }

  ngOnInit() {
  }

}

my-dialog.component.html:

<h1 mat-dialog-title>Lorem Ipsum</h1>
<div mat-dialog-content>
  ...
</div>
<button mat-button mat-dialog-close>Close</button>

app.module.ts:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';

import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { MatCardModule, MatDialogModule, MatButtonModule } from '@angular/material'

import { AppComponent } from './app.component';
import { MyDialogComponent } from './my-dialog/my-dialog.component';

@NgModule({
  declarations: [
    AppComponent,
    MyDialogComponent
  ],
  imports: [
    BrowserModule,
    BrowserAnimationsModule,
    MatCardModule,
    MatDialogModule 
  ],
  providers: [],
  bootstrap: [AppComponent],
  entryComponents: [
    MyDialogComponent
  ]
})
export class AppModule { }

新导入的模块需要添加到imports:

import { MatButtonModule } from '@angular/material/button'

@NgModule{
  ...
  imports: [
    BrowserModule,
    BrowserAnimationsModule,
    MatCardModule,
    MatDialogModule,
    MatButtonModule
  ],
  ...
})
