如何避免向后兼容android应用程序中的样式重复

我有一个基于appcompat兼容性库构建的应用程序。我在values/styles.xml中为我的应用程序定制了一些样式，如按钮、UI等。我有values-11/styles.xml values-16/stylex.xml values-21/styles.xml

我的问题是：我不想在每个styles.xml文件中重复自定义样式代码。我希望较新的版本继承自main syles.xml，只编写新的样式，但此方法不起作用，并且我收到错误，说我没有为我的活动设置主题

以下是我的风格： values/styles.xml：

<resources>
<style name="Holo.Demo" parent="Theme.AppCompat" />
<style name="Holo.Demo.Theme.Light.DarkActionBar" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="mycustomstyle">@drawable/ic_menu_add_user_holo_light</item>

<resources>
<style name="Holo.Demo.Theme.Light.DarkActionBar" parent="Holo.Demo.Theme.Light.DarkActionBar">

</style>

<!--
    Base application theme, dependent on API level. This theme is replaced
    by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
-->
<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
    <!--
        Theme customizations available in newer API levels can go in
        res/values-vXX/styles.xml, while customizations related to
        backward-compatibility can go here.
    -->
</style>

<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>

values-v11/styles.xml：

<resources>
<style name="Holo.Demo" parent="Theme.AppCompat" />
<style name="Holo.Demo.Theme.Light.DarkActionBar" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="mycustomstyle">@drawable/ic_menu_add_user_holo_light</item>

<resources>
<style name="Holo.Demo.Theme.Light.DarkActionBar" parent="Holo.Demo.Theme.Light.DarkActionBar">

</style>

<!--
    Base application theme, dependent on API level. This theme is replaced
    by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
-->
<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
    <!--
        Theme customizations available in newer API levels can go in
        res/values-vXX/styles.xml, while customizations related to
        backward-compatibility can go here.
    -->
</style>

<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>

在我的andoirdmanifest文件中，我已将我的活动主题引用到

Holo.Demo.Theme.Light.DarkActionBar

在Eclipse中创建新项目时，将在values/styles.xml中生成两种样式：

<resources>
<style name="Holo.Demo" parent="Theme.AppCompat" />
<style name="Holo.Demo.Theme.Light.DarkActionBar" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="mycustomstyle">@drawable/ic_menu_add_user_holo_light</item>

<resources>
<style name="Holo.Demo.Theme.Light.DarkActionBar" parent="Holo.Demo.Theme.Light.DarkActionBar">

</style>

<!--
    Base application theme, dependent on API level. This theme is replaced
    by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
-->
<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
    <!--
        Theme customizations available in newer API levels can go in
        res/values-vXX/styles.xml, while customizations related to
        backward-compatibility can go here.
    -->
</style>

<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>

阅读评论，它们很有用。首先，如果您仍在使用AppCompat，请始终使用它。否则：第二，您可能会在“全局”AppTheme中为样式按钮或textview编写一些行，假设它们都存在于所有版本/API中。如果您想更改API 14中引入的smth，则在Eclipse中创建新项目时，将在values/styles.xml中生成两种样式，即在v14样式中编写适当的行AppBASETheme
