If you are extending ActionBarActivity in your MainActivity, you will have to change the parent theme in values-v11 also. So the style.xml in values-v11 will be -

 <!-- res/values-v11/themes.xml -->
 <?xml version="1.0" encoding="utf-8"?>
 <resources>
    <style name="QueryTheme" parent="@style/Theme.AppCompat">
    <!-- Any customizations for your app running on devices with Theme.Holo here -->
    </style>
 </resources>

in AndroidManifest.xml

 <activity
        ...
        android:theme="@style/Theme.AppCompat" />

Did you define style.xml file ? If yes, You have to check for other folders, that contain styles files as well, that could possibly override your styles. – Hardik Joshi Apr 28 '14 at 05:49
So we need to change in All Style.xml file? – user3562853 Apr 28 '14 at 05:51
Yes, you need to change in all style.xml – Hardik Joshi Apr 28 '14 at 05:52
