Solution found by adding these lines to my theme:

    <item name="editTextStyle">@style/Base.V7.Widget.AppCompat.EditText</item>

Answer 2

You should not change the background. It's better if you create a theme, and use theme colors (colorPrimary, colorAccent are the most important for widgets) to get the desired effect. Assign the theme to your EditText and enjoy. Note: you should use one of the AppCompat theme as base theme.

<style name="AppTheme.Base" parent="Theme.AppCompat.NoActionBar">
    <item name="colorPrimary">@color/primary</item>
    <item name="colorAccent">@color/accent</item>
</style>

and in your colors.xml

<color name="primary">#ff0000</color>
<color name="accent">#00ff00</color>
