更改颜色导航栏标题 Ionic 2 [英] Change colour navbar header Ionic 2

问题描述

我有这个问题...我现在的颜色是白色的，我的代码是这样的:

<离子导航栏><离子标题>你好</ion-title></ion-navbar></ion-header>

使用此选项更改颜色很容易(主要、次要、危险、浅色、深色)

<离子导航栏危险><离子标题>你好</ion-title></ion-navbar></ion-header>

但我的问题是当我想使用自定义颜色时.有人知道我该如何解决吗?提前致谢.

最好的问候.

解决方案

有两种方法可以做到这一点，基于是只想在单个页面中更改颜色，还是想在所有页面中更改颜色您应用中的页面:

1) 在单个页面/视图中更改它

就像您可以在此处

看到一样<块引用>

要更改主题，只需调整您的 $colors 地图src/theme/variables.scss 文件:

$colors: (//...新颜色:#55acee)

然后在视图中使用

 <ion-navbar color="newcolor"><离子标题>你好</ion-title></ion-navbar></ion-header>

2) 在所有页面/视图中更改它

在这种情况下，您需要在 variables.scss 文件中添加以下内容以覆盖 Ionic 的默认值:

$toolbar-ios-background: #55acee;$toolbar-md-background: #55acee;$toolbar-wp-background: #55acee;

如何在 app/theme/app.variables.scss 中添加渐变?

您可以在 src/theme/variables.scss 中添加要使用的颜色:

$header-first-color: #AAAAAA;$header-last-color: #000000;

然后设置一个规则来使用它(在你的 app.scss 文件中，如果你想将它应用到每个页面，或者在 page-name.scss如果要将其应用于单个页面):

ion-header {.toolbar-background {背景:线性渐变(135deg，$header-first-color 0%，$header-last-color 100%)；}}

I have this problem... My colour is white right now, my code is like this:

<ion-header >
  <ion-navbar>
    <ion-title>
      HELLO
    </ion-title>
  </ion-navbar>
</ion-header>

Change color with this opcion is easy (primary, secondary, danger, light, dark)

<ion-header >
      <ion-navbar danger>
        <ion-title>
          HELLO
        </ion-title>
      </ion-navbar>
 </ion-header>

but my problem is when I want to use custom colors. Somebody know how can I resolve it? Thanks inadvance.

Best regards.

解决方案

There're two ways of doing this, based on if you want to change the color only in a single page, or if you want to change it in all the pages from your app:

1) Change it in a single page/view

Just like you can see here

To change the theme, just tweak the $colors map in your src/theme/variables.scss file:

$colors: (
  // ...
  newcolor:    #55acee

)

And then use it in the view

 <ion-header>
      <ion-navbar color="newcolor">
        <ion-title>
          HELLO
        </ion-title>
      </ion-navbar>
 </ion-header>

2) Change it in all the pages/views

In this case, you'd need to add the following in your variables.scss file to override Ionic's defaults:

$toolbar-ios-background: #55acee;
$toolbar-md-background: #55acee;
$toolbar-wp-background: #55acee;

Hi, how can I add gradient in app/theme/app.variables.scss?

You could add the colors that you're going to use in the src/theme/variables.scss:

$header-first-color: #AAAAAA;
$header-last-color: #000000;

And then set a rule to use it (in your app.scss file if you want to apply it to every page, or in the page-name.scss file if you want to apply it to a single page):

ion-header {
    .toolbar-background {
        background: linear-gradient(135deg, $header-first-color 0%, $header-last-color 100%);
    }
}
