我需要改变我的应用程序的颜色主题根据一个参数,这应该是一个非常简单的操作。在我的应用程序中,我使用了熔丝角度材质主题。当我尝试从主要主题切换到次要主题时,对话框组件的强调色不会改变,而其他组件(例如导航栏)会改变。
_theme.scss
@import '~@angular/material/theming';
@import './component-themes';
$primary: mat-palette($mat-fusedark);
$accent: mat-palette($mat-light-blue, 600, 400, 700);
$warn: mat-palette($mat-red);
$white: mat-palette($mat-white);
$black: mat-palette($mat-black);
$first-theme: mat-light-theme($primary, $accent, $warn);
$background: map-get($first-theme, background);
$foreground: map-get($first-theme, foreground);
@include angular-material-theme($first-theme);
@include component-themes($first-theme);
$second-primary: mat-palette($mat-fusedark);
$second-accent: mat-palette($mat-green, 600, 400, 700);
$second-warn: mat-palette($mat-red);
$second-theme: mat-light-theme($second-primary, $second-accent, $second-warn);
.second-theme {
@include angular-material-theme($second-theme);
@include component-themes($second-theme);
}component-theme.scss
@import "../partials/navigation";
@import "../partials/dialog";
@mixin component-themes($theme) {
@include navigation-theme($theme);
@include dialog-theme($theme);
}_dialog.scss
@import '~@angular/material/theming';
@mixin dialog-theme($theme) {
$accent: map-get($theme, accent);
.dialog-wrapper {
.mat-dialog-container {
padding: 0;
overflow: hidden;
}
.mat-dialog-title {
display: flex;
flex: 1 1 auto;
justify-content: space-between;
margin: 0;
padding: 24px;
}
.mat-toolbar {
background-color: mat-color($accent) !important;
}
.mat-dialog-content {
padding: 16px 32px 0px;
margin: 0;
}
.mat-dialog-actions {
display: flex;
flex: 1 1 auto;
margin: 1px 0 0 0;
padding: 0px 32px 16px;
}
}
}如果我在_dialog.scss中更改了值
background-color: mat-color($accent) !important;转到
background-color: green !important;它工作正常。看起来mat-color($accent)不起作用,但只适用于该组件的scss。

对于谁遇到这个问题,我终于找到了解决方案。我无法更改某些组件的主题,因为它们是嵌套的,覆盖容器会阻止主题传播。为了修复它,我导入了overlayContainer,并在ngOnInit方法中将主题类添加到overlayContainer中。
import {OverlayContainer} from '@angular/cdk/overlay';
constructor(
private overlayContainer: OverlayContainer
) {}
ngOnInit() {
if (this.data.theme === 'second-theme') {
this.overlayContainer.getContainerElement().classList.add(this.data.theme);
}
}非常简单的解决方案当您知道问题是什么时,最困难的部分是找出它:)
