我正在尝试更改由 eclipse 自动创建的顶部栏的背景。我已经阅读了一些教程，他们建议我更改“styles.xml”文件。这是我到目前为止所做的......
<style name="AppTheme" parent="AppBaseTheme">

<item name="android:windowTitleBackgroundStyle">@style/WindowTitleBackground</item>
</style>
<style name="WindowTitleBackground">

但这不起作用。你能看看它并告诉我这段代码有什么问题吗？因为它没有任何效果。

Make sure you reference this theme in your manifest
确保在清单中引用此主题
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
Then make sure your style is created correctly, previously you referenced a theme parent that wasn't in your code sample.
然后确保您的样式创建正确，之前您引用了不在代码示例中的父主题。
<style name="AppTheme" parent="@android:style/Theme.DeviceDefault">
<item name="android:textColor">#008</item>
<item name="android:windowTitleBackgroundStyle">@style/WindowTitleBackground</item>
</style>
<style name="WindowTitleBackground">
<item name="android:background">#0000FF</item>
</style>
