Android/Eclipse应用主题的麻烦

Question

我是Android新手,似乎挂了一点......

我正在尝试构建我的第一个Android应用程序.该应用程序主要是Eclipse为您创建的模板...

我想使用Holo主题的基础和默认的黑色背景.我可以通过在Manifest中硬编码"@android:style/Theme.Holo"来实现它(在模拟器上).但我不能把它从styles.xml中拉出来.

即使我在Manifest中进行硬编码,Eclipse仍然在Activity编辑器中显示白色背景,这使得在白色背景上设计白色文本变得困难......

我确定这是我想念的小事.请看下面......

先谢谢彼得

Answer 1

这是因为你将它放在res/values/styles.xml文件中,这意味着它被应用于每个API版本的应用程序,但最多10个版本不支持Holo主题.所以,这就是你的文件应该是这样的:

RES /值/ styles.xml

<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.Black">
    <!--
        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>

</resources>

RES /值-V11/styles.xml

<resources>

<!--
    Base application theme for API 11+. This theme completely replaces
    AppBaseTheme from res/values/styles.xml on API 11+ devices.
-->
<style name="AppBaseTheme" parent="android:Theme.Holo">
    <!-- API 11 theme customizations can go here. -->
</style>

</resources>

RES /值-V14/styles.xml

<resources>

<!--
    Base application theme for API 14+. This theme completely replaces
    AppBaseTheme from BOTH res/values/styles.xml and
    res/values-v11/styles.xml on API 14+ devices.
-->
<style name="AppBaseTheme" parent="android:Theme.Holo">
    <!-- API 14 theme customizations can go here. -->
</style>

</resources>
