How to retrieve value from firebase without getting the unique key

Question

I am trying to retrieve an url from Firebase in Android. However, my problem is that I can't retrieve the url without also getting the unique key of the child.

The value I am trying to retrieve is the following:

Down below is the code I use to retrieve the data from firebase.

 final FirebaseDatabase database = FirebaseDatabase.getInstance();
    myRef = database.getReference().child("LoadItems");

    myRef.addValueEventListener(new ValueEventListener() {
        @Override
        public void onDataChange(DataSnapshot dataSnapshot) {
            for(DataSnapshot child : dataSnapshot.getChildren() ){
                String key;
                key = child.getKey();

                Log.d(TAG, "onDataChange: " + key);
                Log.d(TAG, "onDataChange: " + child.getValue());
            }
        }

        @Override
        public void onCancelled(DatabaseError databaseError) { }
    });

So what I am trying to get is what the url alone.
