OnCreateViewholder -如果满足某些条件，如何返回"null“

@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    // 根据 viewType 创建不同类型的 ViewHolder
    if (viewType == TYPE_A) {
        // 创建 ViewHolderA
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_type_a, parent, false);
        return new ViewHolderA(view);
    } else if (viewType == TYPE_B) {
        // 创建 ViewHolderB
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_type_b, parent, false);
        return new ViewHolderB(view);
    } else {
        // 不满足条件，返回 null
        return null;
    }
}
