There's a nice Styles and Themes guideon the android developers site. Basically what you need to do is
android 开发人员站点上有一个很好的样式和主题指南。基本上你需要做的是
- Define a style(or inherit a built-in one). To define a style
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.xmlextension and be saved in theres/values/folder.The root node of the XML file must be
<resources>.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).
在
res/values/项目目录中保存一个 XML 文件。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。XML 文件的根节点必须是
<resources>.对于您要创建的每个样式，向文件中添加一个元素，其名称可以唯一标识该样式（此属性是必需的）。
i.e.
IE
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="Theme.MyGreenTheme" parent="Theme.Light">
<item name="android:windowBackground">#11aa22</item>
</style>
</resources>
It's useful to name the resource file themes.xmlso it's easier to recognize what those styles are used for.
命名资源文件很有用，themes.xml这样可以更容易地识别这些样式的用途。
Applythe defined style to the activity or view that you want stylized. You can either
- set the Activity/Application theme in the manifest file:
<activity android:theme="@style/Theme.MyGreenTheme"/>- or set it dynamically - use the corresponding setter of the Activity class - setTheme().
- 在清单文件中设置活动/应用程序主题：
<activity android:theme="@style/Theme.MyGreenTheme"/>- 或者动态设置它 - 使用 Activity 类的相应设置器 - setTheme()。

Create Custome Views:
创建客户视图：
public class CustomTextView extends AppCompatTextView {
公共类 CustomTextView 扩展 AppCompatTextView {
public CustomTextView(Context context) {
super(context);
setCommonChanges(DefaultTheme.getInstance().textColor, true, context);
}
public CustomTextView(Context context, AttributeSet attrs) {
super(context, attrs);
setDefaultValues(context, attrs);
}
public CustomTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
setDefaultValues(context, attrs);
}
private void setDefaultValues(Context context, AttributeSet attrs) {
TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.CustomTextView);
final int N = a.getIndexCount();
int color = DefaultTheme.getInstance().textColor;
boolean isCustomFont = a.getBoolean(R.styleable.CustomTextView_isCustomFont, true);
for (int i = 0; i < N; ++i) {
int colorIndex = a.getInteger(R.styleable.CustomTextView_tvBackground, 2);
switch (colorIndex) {
case 1:
color = DefaultTheme.getInstance().headingTextColor;
break;
case 2:
color = DefaultTheme.getInstance().textColor;
break;
case 3:
color = DefaultTheme.getInstance().textHintColor;
break;
case 4:
color = DesignUtils.getColorIdFromHexCode("#FFFFFF");
break;
case 5:
color = DefaultTheme.getInstance().iconColor;
break;
case 6:
color = DefaultTheme.getInstance().menuHeaderTextColor;
break;
case 7:
color = DefaultTheme.getInstance().menuTextColor;
break;
case 8:
color = DefaultTheme.getInstance().keyboardtextcolor;
break;
case 9:
color = DesignUtils.getColorIdFromHexCode("#BEBEBE");
break;
}
}
a.recycle();
setCommonChanges(color, isCustomFont, context);
}
private void setCommonChanges(int color, boolean isCustomFont, Context context) {
if (isCustomFont) {
Typeface typeface = DefaultTheme.getInstance().getTVFont(context);
setTypeface(typeface, getTypeface().getStyle());
}
setTextColor(color);
}
public void updateTypeFace(int style){
Typeface typeface = DefaultTheme.getInstance().getTVFont(getContext());
setTypeface(typeface, style);
}
