【问题描述】：

我在 RecyclerView onBindViewHolder 中附加了一个 onClick 侦听器，我正在切换复选框选中状态，但它抛出以下错误报废或附加的视图可能无法回收

ViewHolder中只有一个复选框

override fun onBindViewHolder(holder: BookingSlotListItemViewHolder, position: Int) { 
    holder.timeSlot.setOnClickListener {  view: View? -> 
    holder.timeSlot.toggle()
  }
}

它抛出了这个错误

【问题讨论】：

你的布局文件中的 RecyclerView 上是否有android:animateLayoutChanges=true？
不，没有属性 android:animateLayoutChanges，我在可绘制的 android:stateListAnimator 中制作动画
如果想要切换而不是 seOnClickListener，只需使用 setCheckedChangeListener

标签： android android-recyclerview

【解决方案1】：

尝试使用

override fun onBindViewHolder(holder: BookingSlotListItemViewHolder, position: Int) { 
    holder.timeSlot.setOnClickListener {  view: View? -> 
        if (view is CheckBox) {
            view.toggle()
        }
    }
}

改为。

【解决方案2】：

使用setOnCheckListener 而不是setOnClickListener。

或者试试这个

mGridLayoutManager.setItemPrefetchEnabled(false);

【解决方案3】：

尝试在 ViewHolder 的 init 函数中设置 OnClickListener。
