我在 Horizontal Recycler View 上的 OnclickListener 没有按预期工作

Question

我在 Horizontal Recycler View 上的 OnclickListener 未按预期工作。 它只会将第一个图标更新为存储在其下的图标。 但是当我单击回收站视图中的其他图标时它没有响应。 这是下面的代码

        }
    }
}

我收到一个关于 static 个位置的错误，我通过添加一个名为

adapterPosition

Answer 1

好像是boolean变量check问题。 第一次点击的时候是false，之后没有改成true，所以不会进入设置onClickListener的部分。
