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标识订单所属用户的属性，则可以使用查询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，则您只能使用获得当前用户的订单
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);
