Answer 1

Put the following styles in your styles.xml

<style name="AppTheme" parent="Theme.AppCompat.Light">
        <item name="colorPrimary">@color/primary_color</item>
        <!--<item name="colorPrimaryDark">@color/primary_color</item>-->
        <item name="colorAccent">@color/primary_color</item>
        <item name="actionBarStyle">@style/AppThemeActionBarStyle</item>
</style>

<style name="AppThemeActionBarStyle" parent="@style/Widget.AppCompat.Light.ActionBar">
        <item name="background">@color/your_background_color</item>
</style>

Hope this helps.
