从datepicker中选择日期后，我在recyclerview中使用gridlayout管理器，我通过Firebase云函数传递了一些参数。我从云函数得到的响应是字符串。
如果任何字符串都像（“”）我应该禁用（灰色网格单元）网格单元和其他网格单元应处于活动状态（网格单元颜色为浅蓝色），我将填充网格中的所有字符串）。现在我的问题是，当我选择处于活动状态的网格单元格时，我必须突出显示该单元格。
这里我只能选择活动网格单元，应该是单选。当选择活动网格时，其他活动网格单元应为其他颜色，所选网格单元应为不同颜色。
另外，如果用户再次从日期选择器中选择日期，则我必须刷新网格，并且必须遵循相同的过程。
请帮助我如何实现这一目标，我在选择网格单元时会感到困惑。
