Android自定义视图属性 - 不允许使用“颜色”作为属性名称(Android custom view attributes - 'color' as attribute name disallowed)

 我做了一个简单的自定义视图，一个“ColorSwatch”。 它是圆形的，显示指定的颜色，如果该颜色具有透明度，则在检查器图案上绘制颜色。 视图工作正常。 
 
 我的问题是，当我为swatch定义自定义属性时（在values/attrs_color_swatch_view.xml ），我无法指定名为“color”的属性。 编译器抱怨颜色已经定义，并指向我的colors.xml文件。 作为一种解决方法，我调用了参数swatchColor ，但我更喜欢它只是color 。 
 
 文件： values/attrs_color_swatch_view.xml 
 
<resources>
    <declare-styleable name="ColorSwatchView">
        <attr name="swatchColor" format="color"/><!-- would prefer to simply be 'color', not 'swatchColor' -->
        <attr name="selectionThickness" format="dimension"/>
        <attr name="isSelected" format="boolean"/>
        <attr name="selectionColor" format="color"/>
        <attr name="alphaCheckerSize" format="dimension" />
    </declare-styleable>
</resources>
 
 有没有办法使用属性名称color ？ 或者它是保留的关键字？ 有没有办法以某种方式将它命名为我的视图？ 

I've made a simple custom view, a "ColorSwatch". It's circular, shows the assigned color and if that color has transparency, the color is drawn atop a checker pattern. The view works fine. 
 
My problem is that when I define the custom attributes for the swatch (in values/attrs_color_swatch_view.xml), I can't specify an attribute named "color". The compiler complains that color is already defined, and points me to my colors.xml file. As a workaround, I called the parameter swatchColor, but I'd prefer it to simply be color.
 
The file: values/attrs_color_swatch_view.xml
 
<resources>
    <declare-styleable name="ColorSwatchView">
        <attr name="swatchColor" format="color"/><!-- would prefer to simply be 'color', not 'swatchColor' -->
        <attr name="selectionThickness" format="dimension"/>
        <attr name="isSelected" format="boolean"/>
        <attr name="selectionColor" format="color"/>
        <attr name="alphaCheckerSize" format="dimension" />
    </declare-styleable>
</resources>
 
Is there a way to use the attribute name color? Or is it a reserved keyword? Is there a way to namespace it somehow to my view?
