To apply the theme to all activities, change the style.xml like this:

要将主题应用于所有活动,请像这样更改 style.xml:

<style name="AppTheme" parent="android:Theme.Holo.Light">
    <item name="android:actionBarStyle">@style/ActionBarTheme</item>
</style>

<style name="ActionBarTheme" parent="android:Widget.Holo.Light.ActionBar.Solid.Inverse">
    <item name="android:background">@color/action_bar</item>
</style>

And in colours.xml, use:

在 colours.xml 中,使用:

<color name="action_bar">#BA0000</color>

And in the manifest:

在清单中:

<application
    android:theme="@style/AppTheme" >
