This is themable; look at the windowContentOverlay attribute. In particular, you can create a new theme:

<style name="Theme.Foo" parent="android:style/Theme.Light">
    <item name="android:windowContentOverlay">@null</item>
</style>

And then declare that your activity should use this theme:

<activity android:name=".FooActivity"
          android:theme="@style/Theme.Foo"> ...

Although a better option is to set this theme for all activities in the application, for consistency:

<application android:theme="@style/Theme.Foo"> ...
