报错：java.lang.IllegalStateException: Required view 'selected_cover' with ID 2131296648 for field 'cover' was not found. If this view is optional add '@Nullable' (fields) or '@Optional' (methods) annotation.

报错代码如下：

public class InnerHolder extends RecyclerView.ViewHolder {

    @BindView(R.id.selected_cover)
    public ImageView cover;


    @BindView(R.id.selected_off_prise)
    public TextView offPriseTv;


    @BindView(R.id.selected_title)
    public TextView title;


    @BindView(R.id.selected_buy_btn)
    public TextView buyBtn;


    @BindView(R.id.selected_original_prise)
    public TextView originalPriseTv;


    public InnerHolder(@NonNull View itemView) {
        super(itemView);
        ButterKnife.bind(this,itemView);

}
