ChipGroup - setOnCheckedStateChangeListener语言 - not triggerrin

Question

我试图在一个项目中使用ChipGroup。我正在手动添加芯片项目。它工作得很好。但当我试图点击它时，setOnCheckedStateChangeListener没有触发。我做错了什么?如何解决这个问题?

setContentView(binding.root)
val chipList : ArrayList<String> = arrayListOf()
chipList.add("A")
chipList.add("B")
chipList.add("C")

chipList.forEachIndexed { index, s ->
val chip = Chip(this)
chip.text = s
chip.id = index
binding.chipGroup.addView(chip)

binding.apply {
chipGroup.setOnCheckedStateChangeListener { group, checkedIds ->

Answer 1

添加到checkGroup时应该设置芯片Checkable。
使用这一行

chip.isCheckable = true
