            This sample shows you how to use ActionBarCompat to create a basic Activity which
            displays action items. It covers inflating items from a menu resource, as well as adding
            an item in code. Items that are not shown as action items on the Action Bar are
            displayed in the action bar overflow.


        ]]>
    </string>

</resources>

Create ids.xml under values folder and include following code:

ids.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>


<item name="menu_location" type="id"/>

</resources>

Styles.xml:

template-dimens.xml:

<resources>

    

    <dimen name="margin_tiny">4dp</dimen>
    <dimen name="margin_small">8dp</dimen>
    <dimen name="margin_medium">16dp</dimen>
    <dimen name="margin_large">32dp</dimen>
    <dimen name="margin_huge">64dp</dimen>

    

    <dimen name="horizontal_page_margin">@dimen/margin_medium</dimen>
    <dimen name="vertical_page_margin">@dimen/margin_medium</dimen>

</resources>

template-styles.xml:

<resources>

    

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

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

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

    <style name="Widget" />

    <style name="Widget.SampleMessage">
        <item name="android:textAppearance">?android:textAppearanceMedium</item>
        <item name="android:lineSpacingMultiplier">1.1</item>
    </style>

    <style name="Widget.SampleMessageTile">
        <item name="android:background">@drawable/tile</item>
        <item name="android:shadowColor">#7F000000</item>
        <item name="android:shadowDy">-3.5</item>
        <item name="android:shadowRadius">2</item>
    </style>

</resources>

Create menu folder under res folder and create main.xml under menu folder and include following code:

main.xml:

<?xml version="1.0" encoding="utf-8"?>

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:support="http://schemas.android.com/apk/res-auto" >

    
    <item
        android:id="@+id/menu_refresh"
        android:icon="@drawable/ic_action_refresh"
        android:title="@string/menu_refresh"
        support:showAsAction="ifRoom"/>

    

    
    <item
        android:id="@+id/menu_settings"
        android:icon="@drawable/ic_action_settings"
        android:title="@string/menu_settings"
        support:showAsAction="never"/>

</menu>

layout folder files:

activity_main.xml:

sample_main.xml:

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:padding="16dp"
    android:text="@string/intro_message" />
