Answer 1

您当前正在将 /Order 的所有子节点加载到此处的回收器适配器中：

FirebaseRecyclerOptions<PesanHelperClass> options =
        new FirebaseRecyclerOptions.Builder<PesanHelperClass>()
                .setQuery(FirebaseDatabase.getInstance().getReference().child("Order"), PesanHelperClass.class)
                .build();
prosesAdapter = new ProsesAdapter(options);

如果每个子节点都有一个属性来标识订单所属的用户，您可以使用查询来仅获取特定用户的订单。

因此，例如，如果您使用 Firebase 身份验证并将用户的 UID 存储在每个订单的属性 uid 中，您只能通过以下方式获取当前用户的订单：

if (FirebaseAuth.getInstance().getCurrentUser() != null) {

    //  Determine the UID of the current user
    String uid = FirebaseAuth.getInstance().getCurrentUser().getUid();

    //  Use a query to get only orders for that UID
    DatabaseReference ordersRef = FirebaseDatabase.getInstance().getReference().child("Order");
    Query query = ordersRef.orderByChild("uid").equalTo(uid);

    //  Use the query in the adapter
    FirebaseRecyclerOptions<PesanHelperClass> options =
            new FirebaseRecyclerOptions.Builder<PesanHelperClass>()
                    .setQuery(query, PesanHelperClass.class)
                    .build();
    prosesAdapter = new ProsesAdapter(options);
