问题 I'm writing a DialogFragment for browsing the filesystem, which works really nice by now. I just got one Problem. The files are shown in an ListView, and when the user selects a file, this event is send to the Activity that has called the Fragment over an OnFileSelectedListener-Interface. This is fine for files, but it feels wrong to send out the directory names to the activity, then destroying and recreating the Fragment, when all that should happen is that the Fragment should show a new
