如何覆盖具有自己活动的库的样式 [英] How to override styles of a library which has its own Activity

问题描述

我有一个图书馆，图书馆有自己的带有colorPrimary和colorPrimaryDark属性的活动.在使用该库的应用程序中，这些颜色属性具有不同的值.

I have a library which has its own Activities with colorPrimary and colorPrimaryDark attributes. In the application which is using this library, there are different values for these color attributes.

有没有一种方法可以使库使用调用者应用程序提供的样式?

Is there a way to make the library use the style provided by the caller application?

最后，如果应用程序具有绿色工具栏，则库中的活动将具有绿色工具栏，而不是库主题中定义的工具栏.

So that in the end, if the app has a green toolbar, the activities in the library would have a green toolbar, not the one defined in library theme.

这是图书馆的主题:

<style name="LibraryTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="colorPrimary">@color/red</item>
    <item name="colorPrimaryDark">@color/dark_red</item>
</style>

这是示例应用程序的主题:

And this is the sample app's main theme:

<style name="SampleAppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="colorPrimary">@color/green</item>
    <item name="colorPrimaryDark">@color/dark_green</item>
    <item name="colorAccent">@color/accent_color</item>
</style>

推荐答案

如果"colorPrimary"将使用相同的值-@color/primaryColor，则示例应用程序中的库primaryColor的值将被primaryColor覆盖.

If "colorPrimary" will use the same value - @color/primaryColor, then value of library primaryColor will be overridden by primaryColor in sample app.

如果您在库和应用程序中对"colorPrimary"使用不同的值，例如-@color/libPrimaryColor和@color/appPrimaryColor，则颜色将不同

If you will use different values for "colorPrimary" in library and app, for example - @color/libPrimaryColor and @color/appPrimaryColor then colors will be different
