Nar*_*rxx 28 angular-material2 angular
我正在使用角度材料2构建angular2应用程序.我试图将我的应用程序的背景设置为"正确的方法",但我无法弄清楚如何.
我找到了一个可以在我的<body>元素上使用的类:mat-app-background我可以添加,它给了我一个默认颜色(取决于我是使用浅色还是暗色主题).
我希望定义这种背景颜色以使用我的品牌颜色,但我无法弄清楚如何做到这一点.
在_theming.scss它中定义如下:
// Mixin that renders all of the core styles that depend on the theme.
@mixin mat-core-theme($theme) {
@include mat-ripple-theme($theme);
@include mat-option-theme($theme);
@include mat-pseudo-checkbox-theme($theme);
// Wrapper element that provides the theme background when the
// user's content isn't inside of a `md-sidenav-container`.
.mat-app-background {
$background: map-get($theme, background);
background-color: mat-color($background, background);
}
...
}
所以我认为尝试将背景颜色添加到我的自定义主题是有意义的,不知何故,但我无法理解如何这样做.
在Material2 主题文档中,它只说:
"在Angular Material中,主题是通过组合多个调色板创建的.特别是,主题包括:
如何将我的背景添加到主题中,或以其他任何方式执行此操作？

如果要以干净的方式更改整个应用程序的主题背景颜色,可以使用以下内容覆盖主题.
// Set custom background color
$custom-background-color: map_get($mat-blue-grey, 50);
// -or- Can set colour by hex value too
$custom-background-color: #628cc9;
$background: map-get($theme, background);
$background: map_merge($background, (background: $custom-background-color));
$theme: map_merge($theme, (background: $background));
这假设您已经设置了$theme使用mat-light-theme或mat-dark-theme.当然,您可以替换$mat-blue-grey您选择的颜色映射.
这是我如何使用它的完整示例.我在一个名为的文件中有以下内容theme.scss,它包含在我的angular.json"样式"条目中:
// Include the common styles for Angular Material. We include this here so that you only
// have to load a single css file for Angular Material in your app.
// Be sure that you only ever include this mixin once!
@include mat-core;
// Define the palettes for your theme using the Material Design palettes available in palette.scss
// (imported above). For each palette, you can optionally specify a default, lighter, and darker
// hue.
$primary: mat-palette($mat-red, 600, 400, 900);
$accent: mat-palette($mat-blue-grey, 500, 200, 700);
$background-color: map_get($mat-blue-grey, 50);
// The warn palette is optional (defaults to red).
$warn: mat-palette($mat-blue);
// Create the theme object (a Sass map containing all of the palettes).
$theme: mat-light-theme($primary, $accent, $warn);
// Insert custom background color
$background: map-get($theme, background);
$background: map_merge($background, (background: $background-color));
$theme: map_merge($theme, (background: $background));
// Include theme styles for core and each component used in your app.
// Alternatively, you can import and @include the theme mixins for each component
// that you are using.
@include angular-material-theme($theme);
@include my-app-theme($theme);

// For example Orange palette
$orange-palette: mat.define-palette(mat.$orange-palette);
// Define theme
$theme: mat.define-dark-theme((
color: (
primary: $orange-palette,
accent: $orange-palette
)
));
// Get color param from our theme
$palette-color : map-get($theme, color);
// Get background param from color param
$background: map-get($palette-color, background);
// $background also has background param contains color, set it to red (for example)
$background: map_merge($background, (background: red));
// Set background param for palette
$palette-color: map_merge($palette-color, (background: $background));
// Set palette for theme
$theme: map_merge($theme, (color: $palette-color));
@include mat.all-component-themes($theme);
或者使用函数：
@function mat-set-background($theme, $backgroundColor) {
$palette-color : map-get($theme, color);
$background: map-get($palette-color, background);
$background: map_merge($background, (background: $backgroundColor));
$palette-color: map_merge($palette-color, (background: $background));
@return map_merge($theme, (color: $palette-color));
}
$orange-palette: mat.define-palette(mat.$orange-palette);
$theme: mat.define-dark-theme((
color: (
primary: $orange-palette,
accent: $orange-palette
)
));
$theme: mat-set-background($theme, #FF0000);
@include mat.all-component-themes($theme);

如果要设置背景颜色,您可能希望通过使用自己的替换模拟mat-light-theme或mat-dark-theme功能来自定义整个背景和前景调色板.您的替换品将包括您自己的调色板,而不是mat-light-theme-foreground和background palettes.
示例:https://stackblitz.com/edit/angular-material-custom-background？file = theme.scss
我不知道这种方法是推荐还是官方支持.

不能完全回答您的问题，但是我想很多人最终都会在这里搜索“如何设置应用程序背景色”。
在您project/index.html的身体类别中mat-app-background
<body class="mat-app-background">
<app-root></app-root>
</body>
并确保project/angular.json您拥有：
"styles": [
"./node_modules/@angular/material/prebuilt-themes/YOUR_STYLE.css",
...
],

最近，从 Material 10.x 开始，主题方法正在得到改进。使用新方法mat-light-theme或mat-dark-theme仅接受颜色的配置对象。这是我在评论中发现的：
以前在 Angular Material 中，主题对象直接包含颜色配置。随着最近对主题系统进行重构以允许密度和版式配置，这种情况已不再是这样。
目前，这些方法也支持遗留方法，但我希望很快这将被宣布为一项重大变更。由于我们无法像以前一样将新背景合并到主题对象，因此接受的答案可能不再有效。
我所做的不是那样，而是$mat-light-theme-background在创建新主题之前用我的自定义背景更新了调色板，这完成了工作。
$app-primary: mat-palette($md-light);
$app-accent: mat-palette($mat-pink, A200, A100, A400);
$app-warn: mat-palette($mat-red);
$custom-background-color: map_get($md-light, 50);
$mat-light-theme-background: map_merge($mat-light-theme-background, (background: $custom-background-color));
$light-theme: mat-light-theme((
color: (
primary: $app-primary,
accent: $app-accent,
warn: $app-warn
)
));
注意：$md-light是我为我的应用程序定义的自定义托盘，您可以使用任何其他值。我还尝试过传递“背景”以及其他颜色属性，但由于某种原因不起作用。
包含主题的方式也略有改变。现在有一种新方法需要angular-material-color包含主题。
@include angular-material-color($light-theme);
