Je suppose que vous avez ces champs d'édition de texte dans la mise en page srcdest.xml. Si oui, vous initialisez vos textes d'édition de manière incorrecte. Essayez de les initialiser de cette façon:

LayoutInflater factory = LayoutInflater.from(this); 
    final View textEntryView = factory.inflate(R.layout.srcdest, null); 

    final EditText sourceText = (EditText) textEntryView.findViewById(R.id.sourcetext); 
    final EditText destinationText = (EditText) textEntryView.findViewById(R.id.desttext);
