我有一个带有R ecyclerview的活动，该活动使用一个接收ArrayList的自定义适配器，我需要删除一个单击TextView的特定列表项，问题是当我使用notifyItemRemoved（position）删除onBindViewHolder中的一个项时如果删除第一个元素，然后删除最后一个元素，则会收到IndexOutOfBoundsException。但是，如果我删除第一个到最后一个的所有元素，则可以正常工作。
这是我的完整课程代码：
class FichaDeContactoCompactaAdapter (private val context : Context, private val fichasContacto : ArrayList<FichaContacto>) : RecyclerView.Adapter<FichaDeContactoCompactaAdapter.ViewHolder>() {
inner class ViewHolder(v: View) : RecyclerView.ViewHolder(v){
val titulo = v.findViewById<TextView>(R.id.tituloFichaContactoCompactaTV)
val editar = v.findViewById<TextView>(R.id.editarFCCTV)
val eliminar = v.findViewById<TextView>(R.id.eliminarFCCTV)
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int) : ViewHolder{
val v = LayoutInflater.from(parent.context)
.inflate(R.layout.list_item_ficha_contacto_compacta, parent, false)
return ViewHolder(v)
}
override fun onBindViewHolder(holder: ViewHolder, position: Int){
holder.titulo.text = fichasContacto[position].titulo
holder.editar.setOnClickListener{
Toast.makeText(holder.editar.context, "Elementos en lista: " + fichasContacto.size + "IndiceAcutal: " + position , Toast.LENGTH_SHORT).show()
}
holder.eliminar.setOnClickListener{
Toast.makeText(holder.eliminar.context,"Indice eliminado:" + position + "Elementos en la lista: " + fichasContacto.size, Toast.LENGTH_SHORT).show()
fichasContacto.removeAt(position)
notifyItemRemoved(position)
}
}
override fun getItemCount(): Int {
return fichasContacto.size
}
}
启动的异常是：
java.lang.IndexOutOfBoundsException: Index: 3, Size: 3

答案 0 :(得分：0)
也许您需要记录特定阵列列表 Log.e（“ data”，fishcazContacto.toString）
答案 1 :(得分：0)
解决：
holder.eliminar.setOnClickListener{
fichasContacto.removeAt(position)
notifyItemRemoved(position)
notifyItemRangeChanged(position, fichasContacto.size)
}
