you show the dialog before you set the yes/no buttons. You need to put alertDialog.show(); at the end. Also get rid of super.backPressed(). You do not need it since you are override this original functionality.

Outras dicas
Calling super.onBackPressed()
means "treat the back button normally" (i.e., finish the activity).
Not calling it if you want to intercept it and show a dialog (as is the case) should be enough.
