Android : Android : Calling DialogFragment from Fragment (not FragmentActivity)?

Here's my problem : I do have a FragmentActivity wich contains a Fragment list (with methods to navigate between them) In one of thoose Fragments i need to call a DialogFragment to display a "zoom" on a Picture contained in that fragment.

But it seems that you can't call a DialogFragment directly from a Fragment.

Is there any way to get somekind of "callback" to the FragmentActivity to make this display the DialogFragment over the fragment.

Or simply a "glitch" to call it directly from the Fragment.

If it's the case do you guyz knows a good tutorial about it ?

Best regards,
