So, where is Geneva put what you want.

Inside onClick PositiveButton:

    db.collection("Adresse").whereEqualTo("Adresse", "Geneva").addSnapshotListener(new EventListener<QuerySnapshot>() {
        @Override
        public void onEvent(@Nullable QuerySnapshot queryDocumentSnapshots, @Nullable FirebaseFirestoreException e) {

            if (e != null) {
                Log.w(TAG, "listen:error", e);
                return;
            }

            for (DocumentChange dc : queryDocumentSnapshots.getDocumentChanges()) {

                String docid = dc.getDocument().getId();
                Toast.makeText(getApplicationContext(), docid, Toast.LENGTH_SHORT).show();
            }

        }
    });
