Android 如何动态控制gridview特殊项的视图

我想在gridview项目中控制（删除（使其消失）、添加（使其可见）、设置数据）视图，例如，当用户点击gridview项目中的下载按钮时，网格项目的progressBar在完成下载后运行其进度；dowload按钮消失，open按钮变为可见，可能还有更多操作，如更改delete按钮的背景，在点击下载按钮后匹配我的代码，我的订单正常运行，但当用户浏览gridview时，一些项目会得到与我订购的最后一个网格项目类似的效果[Visibling open button等]我在网格中看到了一些相同的项目，有人能帮我解决这个问题吗？或者提供使用recyclerview替代

这是我的适配器类
