使用ActionBar样式生成器的Android ActionBar样式

Question

I am using this ActionBar Style Generator to style the ActionBar . I have copied the style file and the drawables into the respective folders. But when I try to run the app the following error appears.

This is the style.xml file. The error appears after I add this. I am assigning this theme to an activity in AndroidManifest.xml file:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="Theme.Example" parent="@android:style/Theme.Holo.Light">
        <item name="android:actionBarItemBackground">@drawable/selectable_background_example</item>
        <item name="android:popupMenuStyle">@style/PopupMenu.Example</item>
        <item name="android:dropDownListViewStyle">@style/DropDownListView.Example</item>
        <item name="android:actionBarTabStyle">@style/ActionBarTabStyle.Example</item>
        <item name="android:actionDropDownStyle">@style/DropDownNav.Example</item>
        <item name="android:actionBarStyle">@style/ActionBar.Solid.Example</item>
        <item name="android:actionModeBackground">@drawable/cab_background_top_example</item>
        <item name="android:actionModeSplitBackground">@drawable/cab_background_bottom_example</item>
        <item name="android:actionModeCloseButtonStyle">@style/ActionButton.CloseMode.Example</item>
    </style>
    <style name="ActionBar.Solid.Example" parent="@android:style/Widget.Holo.Light.ActionBar.Solid">
        <item name="android:background">@drawable/ab_solid_example</item>
        <item name="android:backgroundStacked">@drawable/ab_stacked_solid_example</item>
        <item name="android:backgroundSplit">@drawable/ab_bottom_solid_example</item>
        <item name="android:progressBarStyle">@style/ProgressBar.Example</item>
    </style>
    <style name="PopupMenu.Example" parent="@android:style/Widget.Holo.Light.ListPopupWindow">
        <item name="android:popupBackground">@drawable/menu_dropdown_panel_example</item>
    </style>
    <style name="DropDownListView.Example" parent="@android:style/Widget.Holo.Light.ListView.DropDown">
        <item name="android:listSelector">@drawable/selectable_background_example</item>
    </style>
    <style name="ActionBarTabStyle.Example" parent="@android:style/Widget.Holo.Light.ActionBar.TabView">
        <item name="android:background">@drawable/tab_indicator_ab_example</item>
    </style>
    <style name="DropDownNav.Example" parent="@android:style/Widget.Holo.Light.Spinner">
        <item name="android:background">@drawable/spinner_background_ab_example</item>
        <item name="android:popupBackground">@drawable/menu_dropdown_panel_example</item>
        <item name="android:dropDownSelector">@drawable/selectable_background_example</item>
    </style>
    <style name="ProgressBar.Example" parent="@android:style/Widget.Holo.Light.ProgressBar.Horizontal">
        <item name="android:progressDrawable">@drawable/progress_horizontal_example</item>
    </style>
    <style name="ActionButton.CloseMode.Example" parent="@android:style/Widget.Holo.Light.ActionButton.CloseMode">
        <item name="android:background">@drawable/btn_cab_done_example</item>
    </style>
</resources>

The error I got is:

Execution failed for task ':app:processDebugManifest'.
> com.android.manifmerger.ManifestMerger2$MergeFailureException: org.xml.sax.SAXException: NAMESPACE_ERR: An attempt is made to create or change an object in a way which is incorrect with regard to namespaces.
org.w3c.dom.DOMException: NAMESPACE_ERR: An attempt is made to create or change an object in a way which is incorrect with regard to namespaces.

Please help me. This issue is driving me nuts!

Wherever you declare the parent tag with @android:style , you need to change it to @style . For example:

parent="@android:style/Widget.Holo.Light.ActionBar.Solid">

Should change to:

parent="@style/Widget.Holo.Light.ActionBar.Solid">

Make the same change as above to other styles that you have declared in your styles.xml file.

Tip : If you are using Eclipse to develop Android, press Ctrl+Left-Click at the same time on a parent tag to show the style's definition. If the style is defined correctly, pressing Ctrl+Left-Click will open the corresponding Android's styles.xml file. If the styles.xml file is not opened after you Ctrl+Left-Click on it, then you know you have a problem with your Android's tag declaration.
