更改firebase中listviewitems的布尔值

public class Item {
    private String id;
    private String name;
    private boolean isSelected;

    public Item() {
        // Default constructor required for calls to DataSnapshot.getValue(Item.class)
    }

    public Item(String id, String name, boolean isSelected) {
        this.id = id;
        this.name = name;
        this.isSelected = isSelected;
    }

    // Getters and setters
    public String getId() { return id; }
    public void setId(String id) { this.id = id; }

    public String getName() { return name; }
    public void setName(String name) { this.name = name; }

    public boolean isSelected() { return isSelected; }
    public void setSelected(boolean selected) { isSelected = selected; }
}

DatabaseReference databaseReference = FirebaseDatabase.getInstance().getReference("items");

List<Item> itemList = new ArrayList<>();
ArrayAdapter<Item> adapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, itemList);
ListView listView = findViewById(R.id.listView);

        itemList.clear();
        for (DataSnapshot snapshot : dataSnapshot.getChildren()) {
            Item item = snapshot.getValue(Item.class);
            itemList.add(item);
        }
        adapter.notifyDataSetChanged();
    }

    @Override
    public void onCancelled(@NonNull DatabaseError databaseError) {
        // Handle possible errors.
    }

// 假设您有一个方法来处理 ListView 的点击事件
public void onItemClick(int position) {
    Item item = itemList.get(position);
    item.setSelected(!item.isSelected());
    databaseReference.child(item.getId()).setValue(item);
