Solution 1:

The problem is you are trying to convert a string ( the values in OrderDetails) to OrderDetails object

Answer :

databaseReference = FirebaseDatabase.getInstance().getReference().child("Admin Order").
            child(userID);
    databaseReference.addValueEventListener(newValueEventListener() {
        @OverridepublicvoidonDataChange(@NonNull DataSnapshot dataSnapshot) {
            for (DataSnapshot childSnapshot : dataSnapshot.getChildren()) {
                OrderDetails orderDetails = childSnapshot.child("Order Details").getValue(OrderDetails.class);
                Log.w("orderDetails", orderDetails.getConsumer());
                mList.add(details);
                progressBar.setVisibility(View.INVISIBLE);
            }
            adapter = newPreviousOrderAdapter(getContext(), mList);
            recyclerView.setAdapter(adapter);
        }

        @OverridepublicvoidonCancelled(@NonNull DatabaseError databaseError) {
            progressBar.setVisibility(View.INVISIBLE);
        }
    });
