*I'd like to use a color from an hexa string such as `"#FFFF0000"` to (say) change the background color of a Layout.* **我想使用六角形字符串中的颜色，例如`"#FFFF0000"`来（例如）更改布局的背景颜色。** *`Color.HSVToColor` looks like a winner but it takes a `float[]` as a parameter.* **`Color.HSVToColor`看起来像赢家，但它需要一个`float[]`作为参数。**

*Am I any close to the solution at all?* **我是否接近解决方案？**

*XML file saved at res/values/colors.xml:* **保存在res / values / colors.xml的XML文件：**

<?xml version="1.0" encoding="utf-8"?>
    <resources>
       <color name="opaque_red">#f00</color>
       <color name="translucent_red">#80ff0000</color>
    </resources>

*This application code retrieves the color resource:* **此应用程序代码检索颜色资源：**

Resources res = getResources();
    int color = res.getColor(R.color.opaque_red);

*This layout XML applies the color to an attribute:* **此布局XML将颜色应用于属性：**

*If you define a color in your XML and want to use it to change background color or something this API is the one your are looking for:* **如果您在XML中定义颜色并希望使用它来更改背景颜色或某些内容，则此API就是您要查找的颜色：**

((TextView) view).setBackgroundResource(R.drawable.your_color_here);

*In my sample I used it for TestView* **在我的示例中，我将它用于TestView**
