当我尝试从Firebase实时数据库将数据获取到回收者视图时出现此错误

Question

这是我在执行应用程序时遇到的异常

com.google.firebase.database.DatabaseException: Class com.example.gcsmdealer.orders does not define a no-argument constructor. If you are using ProGuard, make sure these constructors are not stripped.

这是我用于获取数据的代码。我通过使用快照获取值，并用于初始化我的订单（这是我的订单模型类）类，我使用该类并将其添加到我的订单数组列表中，并在创建Adapter对象之后，然后使用了i set到recyclerview的适配器

reference= FirebaseDatabase.getInstance().getReference().child("orders");
        reference.addValueEventListener(new ValueEventListener() {
            @Override
            public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
                for (DataSnapshot snapshot:dataSnapshot.getChildren()){
                    orders orders=snapshot.getValue(orders.class);
                    ordersArrayList.add(orders);
                }
                orderAdapter=new OrderAdapter(CustomerOrders.this,ordersArrayList);
                recyclerView.setAdapter(orderAdapter);
            }

            @Override
            public void onCancelled(@NonNull DatabaseError databaseError) {
                Toast.makeText(CustomerOrders.this, "Something Went Wrong! Try Again Later", Toast.LENGTH_SHORT).show();
            }
        });
