在回收视图中过滤产品列表- android

// 假设有一个ProductAdapter类继承自RecyclerView.Adapter
public class ProductAdapter extends RecyclerView.Adapter<ProductAdapter.ProductViewHolder> {
    private List<Product> productList;

    public ProductAdapter(List<Product> productList) {
        this.productList = productList;
    }

    // 更新数据集并通知RecyclerView
    public void updateData(List<Product> filteredList) {
        this.productList = filteredList;
        notifyDataSetChanged();
    }
}

// 在Activity或Fragment中进行过滤操作
private void filterProducts(String query) {
    List<Product> filteredList = new ArrayList<>();
    for (Product product : originalProductList) {
        if (product.getName().toLowerCase().contains(query.toLowerCase())) {
            filteredList.add(product);
        }
    }
    productAdapter.updateData(filteredList);
}
