Android:如何为不同的android版本使用不同的主题？

Question

MinSDKVersion = 7 TargetSDKVersion = 17

如果用户有 SDKVersion 11 或更高版本，我喜欢将主题设置为 Theme.Holo.Light。 它在这里对我不起作用。当我在 3.1 设备上启动应用程序时，它只使用 Theme.Light:

当我在低于 3.1 版本的设备上运行这个应用程序时也是如此

我的文件夹结构:

list :

    <application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/MyTheme" >

值-v11:

<resources>

<!--
    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="@android:style/Theme.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="@android:style/Theme.Light">
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>


<style name="MyTheme" parent="@android:style/Theme.Holo.Light">
    <!-- Any customizations for your app running on devices with Theme.Holo here -->
</style>

其他值文件夹:

<resources>

<!--
    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="@android:style/Theme.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="@android:style/Theme.Light">
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>

    <style name="MyTheme" parent="@android:style/Theme.Light">
    <!-- Any customizations for your app running on devices with Theme.Holo here -->
</style>

如何正确使用它？

为什么您的主题在 styles.xml 文件中有两次？

<style name="AppTheme" parent="@android:style/Theme.Light">
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>


<style name="MyTheme" parent="@android:style/Theme.Holo.Light">
    <!-- Any customizations for your app running on devices with Theme.Holo here -->
</style>

删除你不需要的(在本例中是 Theme.Light 主题):

值-v11:

<style name="MyTheme" parent="@android:style/Theme.Holo.Light">
    <!-- Any customizations for your app running on devices with Theme.Holo here -->
</style>

值(value)观:

<style name="MyTheme" parent="@android:style/Theme.Light">
    <!-- Any customizations for your app running on devices with Theme.Holo here -->
</style>
