I am using gridlayout manager in recyclerview after selecting the date from datepicker i am passing some parameters through firebase cloud function.The response which i am getting from cloud function is string.
I will populate all the strings in grid if any of the string is like("") i should disable(grid cell in grey color) that grid cell and the other grid cell should be active(grid cell color is light blue).Now my issue is when i select the grid cell which is active i have to highlight that cell.
Here i can able to select only active grid cells and it should be single select.when selecting active grid other active grid cells should be in someother color selected grid cell should be in different color.
Also if the user again selects the date from datepicker i have to refresh the grid and i have to follow the same process.
Please help me how to achieve this i am messing up with selecting the grid cells.
