12 | * MultiThemeAttrs是一个Attribute的数组，用来注解MultiTheme支持的主题控件类。
13 | *
14 | * 这些Attribute是具体View的对应Styleable中的值
15 | * 这些值不但是作为MultiTheme中用来索引的Key，也是通过其从XML解析出的Attribute中取出主题元素的值的关键。
16 | *
17 | * 例:
18 | * android:background="?attr/theme_background"
19 | *
20 | * View中都有'android.R.attr.background'的标签，添加其作为View的MultiThemeAttrs，那么MultiTheme
21 | * 就会将'background'标签下的'theme_background'对应attrRes取出，作为主题元素的值来存储。当主题改变
22 | * 的时候，通过'android.R.attr.background'找到attrRes，然后分发到对应的
23 | * {@link io.github.leonhover.theme.widget.ViewWidget}的'applyElementTheme'。
