How to reference a color in a android xml resource that is defined in a lib?
问题
I have an android fragment app/src/main/res/layout/fragment_main.xml that references a color bg_line defined in app/src/main/res/values/colors.xml
res/values/colors.xml :
<resources>
<color name="bg_line">#E7E7E7</color>
...
</resources>
fragment_main.xml :
<RelativeLayout android:background="@color/bg_line" ... >...
I want to refactor my existing working code and move color bg_line into a different android library module mylib/src/main/res/values/colors.xml that uses
mylib/src/main/manifest.xml :
<manifest package="de.k3b.mylib" ...>
My Question: how can i reference the color bg_line in fragment_main.xml if bg_line is defined in module mylib
In https://developer.android.com/guide/topics/resources/color-list-resource i found
> resource reference:
> In Java: R.color.filename
> In XML: @[package:]color/filename
I found no example use for [package:]
i tried
android:background="@android:color/bg_line"android:background="@app:color/bg_line"android:background="@mylib:color/bg_line"android:background="@de.k3b.mylib:color/bg_line"

- I found no example use for [package:]
i tried
- android:background="@android:color/bg_line"
- android:background="@app:color/bg_line"
- android:background="@mylib:color/bg_line"
- android:background="@de.k3b.mylib:color/bg_line"

包含布局片段 main.xml 的模块必须实现（Gradle）包含颜色定义的模块（:mylib）。因此，它只是将颜色引用为 "before"（android:background="@color/bg_line"）。
英文:
the module that contains the layout fragment main.xml must implement (gradle) the module (:mylib) where the color definition is found. So it's just referencing the color as "before" (android:background="@color/bg_line").
