如何在Android中将以前的数据保存在复选框中

Background -这是一个场景，我的应用程序是一个物联网应用程序.现在的情况是我必须在房间部分创建一组物联网设备.但条件总是相同类型的设备必须在该组中 Select ，如果在房间里有4个设备，其中2支持RGB和其他支持温暖和冷白色，然后该组时，我会创建它将显示所有设备与复选框与不同的类别.如果我在任何设备上打勾，那么其他设备类别将被禁用(不是同一个).因为我想让用户创建相同类别的组.

Problem-现在，正如我提到的问题，如果我不在小组中做出任何改变，它也无法挽救它.

private fun createSelectedDevices() {
        val selectedNodes = JsonArray()
        val disSelectedNodes = JsonArray()
        val distinctDevices = devices.distinctBy { it.nodeId } as ArrayList<Device>

        if (selectedDevices.isNullOrEmpty()) {
            //Error happening when we edit the Group Name or not
            alertErrorManagement(
                "Please select devices",
                "",
                ErrorObject.EXCEPTION,
                R.drawable.ic_error_background
            )
            return
        } else {
            for (device in selectedDevices) {
                if (device.selectedState == 1) {
                    selectedNodes.add(device.nodeId)
                } else {
                    disSelectedNodes.add(device.nodeId)
                }
            }

            if (selectedNodes.isEmpty && disSelectedNodes.isEmpty) {
                alertErrorManagement(
                    "Please select devices",
                    "",
                    ErrorObject.EXCEPTION,
                    R.drawable.ic_error_background
                )
                return
            }
        }

        if (!disSelectedNodes.isEmpty) {
            updateGroupRemove(disSelectedNodes, selectedNodes)
        } else {
            updateGroupAdd(selectedNodes)
        }

    }

现在在这段代码alertErrorManagement是一个弹出消息，将显示当用户没有 Select 任何设备(而编辑组我给用户的权限来更改它的组名太).现在假设您创建了一个包含1个设备的组.如果您try 单击组中的编辑按钮，而不更改组名称或设备 Select 等任何内容，则直接单击保存按钮.它将显示弹出消息Please Select Devices，这是错误的，因为已经 Select 了1个 node 或设备.在代码中，它提到了上面的if-condition.但如果我 Select 相同的设备并取消勾选复选框.之后，如果我点击同一设备并勾选复选框.它将显示Group Updated Successfully的弹出消息.

我try 查看SelectedDevice.kt类文件，但没有看到任何错误.

作为一名Android新手，我不太清楚我应该go 哪里看.
