Dialog fragment embedding depends on device

问题

In my app user picks phone number either from contacts or call log. Picking contacts is quite simple and works nice both on phones and tablets - i. e. on phones new fullscreen activity is popped up and on tables I see nice popup dialog with list of contacts.

It seems that there is no way to pick phone number from call log, so I had to implement my own activity (via ListFragment). I would like to achive same behavior as with contacts - on tablets I want to see popup dialog with list view, and on phones I want to see fullscreen activity.

It is possible to achive what is drawn on this pic without having code like: "if this is tabled then show popup else start new activity", and use only styles / layouts which are picked automatically depends on device?

It seems that simpiest solution - I use ListFragment and don't want to sacrifice it to DialogFragment - is to create different themes depends on resolution (and platform).

For example:

AndroidManifest.xml

<activity
    android:name="CallLogActivity"
    android:theme="@style/dialog_or_activity">
</activity>

\values-xlarge-v11\styles.xml

<resources>
    <style name="dialog_or_activity" parent="android:Theme.Holo.Light.Dialog">                 
    </style>
</resources>

\values\styles.xml

<style name="dialog_or_activity" parent="android:Theme">        
</style>
