如何在Android中更改操作栏的背景颜色？

Question

I was working hard to achieve this but I had no luck. What I tried to do is to change the background color from the style that I attached in my main style tag. This is my code:

<resources>

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

<style name="MyActionBar" parent="@android:style/Widget.Holo.Light.ActionBar">
    <item name="android:background">#2E495E</item>
</style>

Still nothing changed. I get this in my application:

Answer 1

I had the same issue and it's probably the same problem you were having. Notice the docs say the following:

each style property that you declare must be declared twice..

So my issue was I declared it for 2.1 and up, but not for 3.0 and greater so my Galaxy S4 of course could not see any changes to the colours I was making.

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light">
    <item name="android:actionBarStyle">@style/MyActionBar</item>

    <!--Support Library compatibility-->
    <item name="actionBarStyle">@style/MyActionBar</item>
</style>

<!-- ActionBar styles -->
<style name="MyActionBar"
    parent="@style/Widget.AppCompat.Light.ActionBar">

    <item name="android:background">@color/green</item>

    <!--Support Library compatibility-->
    <item name="background">@color/green</item>
</style>

<style name="NoActionBar" parent="Theme.AppCompat.Light">
    <item name="android:windowNoTitle">true</item>
</style>

Answer 2

ActionBar bar = getActionBar();
bar.setBackgroundDrawable(new ColorDrawable("COLOR"));

Answer 3

Is this the only style.xml you have? Else check if you are modifying for the right API
