Question

我有一个包含自定义元素的卡片视图的回收者视图。一切正常，但是当我滚动卡片列表时，卡片视图会改变位置。我该如何控制它。

这是我的适配器类。

public class ProductAdapter extends RecyclerView.Adapter<ProductAdapter.ProductViewHolder> {

ArrayList<Product> Products = new ArrayList<Product>();


public  ProductAdapter(ArrayList<Product> Products)
{

    this.Products = Products;
}


@Override
public ProductViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

    View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.card_view_layout,parent,false);

    ProductViewHolder ProductViewHolder = new ProductViewHolder(view);

    return ProductViewHolder;
}

@Override
public void onBindViewHolder(ProductViewHolder holder, int position) {

        Product product = Products.get(position);

        holder.pic.setImageBitmap(product.getBitmap());
        holder.name.setText(product.getName());
        holder.size.setText(product.getSize());
        holder.price.setText(product.getPrice());



}

@Override
public int getItemCount() {
    return Products.size();
}

public static class ProductViewHolder extends RecyclerView.ViewHolder {

    private ImageView pic;
    private TextView name,size,price;

    public ProductViewHolder(View view)
    {
        super(view);
        pic = (ImageView) view.findViewById(R.id.pic);
        name  = (TextView) view.findViewById(R.id.name);
        size = (TextView) view.findViewById(R.id.size);
        price = (TextView) view.findViewById(R.id.price);

    }
}

}

Answer 1

将LinearLayout的layout_height更改为“wrap_content”。它会起作用。

Answer 2

我认为你需要覆盖这些方法......

@Override
public int getItemViewType(int position) {
    return position;
}

@Override
public long getItemId(int position) {
    return position;
}

Recyclerview中的卡片视图在滚动时更改位置。
