推荐答案

有一个不错的样式和主题指南" .基本上你需要做的是

There's a nice Styles and Themes guide on the android developers site. Basically what you need to do is

1. 定义样式(或继承内置样式一).定义样式

1. Define a style (or inherit a built-in one). To define a style

将XML文件保存在项目的 res/values/目录中.这XML文件的名称是任意的，但必须使用 .xml 扩展名并保存在 res/values/文件夹中.

save an XML file in the res/values/ directory of your project. The name of the XML file is arbitrary, but it must use the .xml extension and be saved in the res/values/ folder.

XML文件的根节点必须是< resources> .

The root node of the XML file must be <resources>.

对于要创建的每种样式，在文件中添加一个元素带有唯一标识样式的名称(此属性为必填).

For each style you want to create, add a element to the file with a name that uniquely identifies the style (this attribute is required).

即

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="Theme.MyGreenTheme" parent="Theme.Light">
        <item name="android:windowBackground">#11aa22</item>
    </style>
</resources>

将资源文件命名为 themes.xml 很有用，因此更容易识别这些样式的用途.

It's useful to name the resource file themes.xml so it's easier to recognize what those styles are used for.
