Firebase Android FirebaseRecyclerAdapter不适用于两个不同的查询

Question

我正在尝试在同一页面上显示来自两个不同数据库的数据。我使用FirebaseRecyclerAdapter。我的问题是，当我打开该页面时，仅显示第一个数据，当我关闭它并再次打开时，则显示两个数据页面。当我使用相同的数据库时，第一次访问时都会显示两个数据。知道这有什么解决方案吗？我试图查看查询是否错误，但是第一次甚至第二次都没有打印任何东西。

    ordersDatabase.keepSynced(true);
    ordersDoneDatabase.keepSynced(true);

    LinearLayoutManager linearLayoutManager = new LinearLayoutManager(OldOrdersActivity.this);
    LinearLayoutManager linearLayoutManager2 = new LinearLayoutManager(OldOrdersActivity.this);

    linearLayoutManager.setReverseLayout(true);
    linearLayoutManager.setStackFromEnd(true);

    linearLayoutManager2.setReverseLayout(true);
    linearLayoutManager2.setStackFromEnd(true);

    activeOrders.setHasFixedSize(true);
    doneOrders.setHasFixedSize(true);

    activeOrders.setLayoutManager(linearLayoutManager);
    doneOrders.setLayoutManager(linearLayoutManager2);

    final Query orderByUserId = ordersDatabase.orderByChild("curUser").equalTo(current_user_id);
    FirebaseRecyclerAdapter<Order, OldOrdersActivity.OrdersViewHolder> firebaseOrderAdapter = new FirebaseRecyclerAdapter<Order, OldOrdersActivity.OrdersViewHolder>(
            Order.class,
            R.layout.model,
            OldOrdersActivity.OrdersViewHolder.class,
            orderByUserId
    ) {
        @Override
        protected void populateViewHolder(final OldOrdersActivity.OrdersViewHolder ordersViewHolder, final Order order, int i) {

            final String orderKey = getRef(i).getKey();
            DatabaseReference myOrders = rootRef.child("Orders").child(orderKey);

            myOrders.addValueEventListener(new ValueEventListener() {
                @Override
                public void onDataChange(@NonNull DataSnapshot dataSnapshot) {...
                }
                @Override
                public void onCancelled(@NonNull DatabaseError databaseError) {

                }
            });
        }
    };

和第二个Firebase适配器：

        final Query orderByStatusTrue = ordersDoneDatabase.child(firebaseAuth.getUid()).orderByChild("orderStatus").equalTo(true);
    FirebaseRecyclerAdapter<Order, OldOrdersActivity.OrdersViewHolder> firebaseOrderAdapterStatusTrue = new FirebaseRecyclerAdapter<Order, OldOrdersActivity.OrdersViewHolder>(
            Order.class,
            R.layout.model,
            OldOrdersActivity.OrdersViewHolder.class,
            orderByStatusTrue
    ) {
        @Override
        protected void populateViewHolder(final OldOrdersActivity.OrdersViewHolder ordersViewHolder, final Order order, int i) {

            final String orderKey = getRef(i).getKey();
            DatabaseReference myOrders = rootRef.child("Orders_done").child(current_user_id).child(orderKey);


            myOrders.addValueEventListener(new ValueEventListener() {
                @Override
                public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
                    ...
                }

                @Override
                public void onCancelled(@NonNull DatabaseError databaseError) {

                }
            });
        }
    };

    activeOrders.setAdapter(firebaseOrderAdapter);

    doneOrders.setAdapter(firebaseOrderAdapterStatusTrue);
