如何设置Android应用的背景色和操作栏背景

Question

I am trying to modify my app to have a dark blue action bar with a light blue background. So far I have only been able to make the entire app dark blue. How can I modify my code to keep the action bar the color it is now but make the background with the team numbers a light blue? Please note my apps minimum API is 14.

I am currently using the following code in my styles.xml:

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="android:background">@color/teamLightBlue</item>
</style>

<!-- Activity themes -->

<style name="Theme.Base" parent="android:Theme.Light" />

<style name="Theme.Sample" parent="Theme.Base" />


<!-- the theme applied to the application or activity -->
<style name="CustomActionBarTheme"
    parent="AppTheme">
    <item name="android:actionBarStyle">@style/MyActionBarTheme</item>
</style>

<!-- ActionBar styles -->
<style name="MyActionBarTheme" parent="@android:style/Widget.Holo.Light.ActionBar">
    <item name="android:background">@color/teamDarkBlue</item>
</style>

Answer 1

If you choose to use Theme.AppCompat , you can change Action Bar's background color using:

<item name="colorPrimary">#ffffff</item>

but if you choose the Holo one, you can change that color using

<item name="android:colorPrimary">#ffffff</item>

Hope this helps.

As far as I know your code is good instead of Widget.Holo.Light.ActionBar as its not part of AppCompat v7. Use this instead

<style name="CustomActionBarTheme" parent="AppTheme">
    <item name="android:actionBarStyle" tools:ignore="NewApi">@style/MyActionBarTheme</item>
    <item name="actionBarStyle">@style/MyActionBarTheme</item>
</style>
<style name="MyActionBarTheme" parent="@style/Widget.AppCompat.Light.ActionBar.Solid.Inverse">
    <item name="android:background">@color/teamDarkBlue</item>
    <item name="background">@color/teamDarkBlue</item>
</style>

It should work fine!
