Android 是否可以从布局资源访问颜色类的颜色？

我知道如何访问res文件夹中定义的颜色：

//定义

<resources> 
    <color name="white">#ffffff</color>
</resources>

即使是由Android定义的默认颜色：

android:background="@android:color/widget edittext dark"

但是我不知道是否可以从

布局中使用
Color
类中定义的颜色：

Color.MAGENTA

谢谢
 您可以从Color类复制值并将它们放在您自己的颜色资源文件中？
我认为您不能从xml访问它们，但是您可以在运行时从java code
mButton.setBackgroundColor（Color.MAGENTA）更改背景色
或者通过另一种方式，您可以创建一个
xml
文件，然后引用它们

下面是一个示例颜色xml文件：

这不能在xml布局中完成，但仍可以在Java运行时使用以下代码完成：

myLayout.setBackgroundColor(Color.MAGENTA);

OP想知道是否可以使用
Color
类中定义的颜色。他已经知道如何访问res文件夹中定义的颜色。我想他想问的是，是否可以在他的layout.xml中使用类似于
android:background=“Color.MAGENTA”
的东西。我认为这是不可能的。是的，这就是我想知道的：）谢谢Sash_KP，我刚刚修改了我的答案。我想你要问的是，是否可以在你的
布局.xml
中使用类似于
android:background=“Color.MAGENTA”
的东西，我认为这是不可能的。
myLayout.setBackgroundColor(Color.MAGENTA);
