style.xml和theme.xml android studio之间的区别？

Question

Hey I'm trying to change the background of my action bar but I'm not quiet sure I understand the structure of the style files. So basically I have style.xml which is to pass on some elements a desired style. Then I've Theme.xml which is to have a group of styles in it, correct ? How do you link the two in other words how do I tell the theme I want the specified style in it ? I can't manage to change the background of the action bar so here is my code:

style.xml:

    <!-- Base application theme. -->
    <style name="MyActionBar" parent="Theme.AppCompat.Light.DarkActionBar">
        <item name="android:colorBackground">@color/color_lightBlue</item>
    </style>
</resources>

theme.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
 <style name="MyCustomTheme" parent="Theme.AppCompat.Light">

 </style>

</resources>

and wtf is v11/style ?

Whether you put the attributes in styles.xml or theme.xml , they have the same effect finally if you apply the theme to your app or activity. In your AndroidManifest.xml , in order to let the theme have the effect you want, you should apply your customized theme like following to your app.

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
