Kotlin 为什么我的子模型不能转换为java.util.ArrayList,kotlin,android-recyclerview,Kotlin,Android Recyclerview,我正在使用多级数据创建一个recyclerview，将数据输入子适配器时出现问题。出现如下错误“模型无法转换为java.util.ArrayList android” 我的json [{ "header" : "buah air", "sub" : { "warna" : "merah", "jenis" : "air" } },{ "header" : "bua

我正在使用多级数据创建一个recyclerview，将数据输入子适配器时出现问题。出现如下错误“模型无法转换为java.util.ArrayList android”

我的json

[{
    "header" : "buah air",
    "sub"    : {
                "warna" : "merah",
                "jenis" : "air"
               }
     },{
    "header" : "buah serat",
    "sub"    : {
                "warna" : "hijau",
                "jenis" : "serat"
               }

}]

我的模型

data class mTOP (
    val header : String,
    @SerializedName("sub") val sub : mSubTOP
)

data class mSubTOP(
    val warna : String,
    val jenis : String
)

我的主要活动

val adapter =  adapter_top(response!!.body() as ArrayList<mTOP>)
rv.adapter = adapter

val adapter=adapter\u top（响应！！.body（）作为ArrayList）
rv.适配器=适配器

我的适配器\u top（此处发生错误）

覆盖BindViewHolder（holder:adapter\u top.ViewHolder，位置：Int）{
holder.tvHeader？.text=Datane[position]。header
holder.rvList？.layoutManager=LinearLayoutManager（holder.rvList.context，LinearLayout.VERTICAL，false）
var adapterSub=适配器（Datane[position].sub作为ArrayList）
保持架.rvList？.adapter=adapterSub
}

我的适配器

class adapter_sub(val Datane: ArrayList<mSubTOP>): RecyclerView.Adapter<adapter_sub.ViewHolder>() {

}

class adapter_sub(val Datane: ArrayList<mSubTOP>): RecyclerView.Adapter<adapter_sub.ViewHolder>() {

    override fun onBindViewHolder(holder: adapter_sub.ViewHolder, position: Int) {
        val location = Datane[position]
        holder.tvName?.text = location.warna
        holder.tvHobi?.text = location.jenis

    }

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): adapter_sub.ViewHolder {
        val v = LayoutInflater.from(parent.context).inflate(R.layout.layout_sub, parent, false)
        return ViewHolder(v)
    }

    override fun getItemCount(): Int {
        return Datane.size
    }

    class ViewHolder(itemView: View): RecyclerView.ViewHolder(itemView) {
        val tvName = itemView.findViewById<TextView>(R.id.tvJenis)
        val tvHobi = itemView.findViewById<TextView>(R.id.tvWarna)
    }
}

class adapter\u sub（val-Datane:ArrayList）：RecyclerView.adapter（）{
}

因为它根本不是

数组列表：）您必须创建一个包含一个元素的列表：
adapter_sub(arrayListOf(Datane[position].sub))

这就完成了我的适配器
class adapter_sub(val Datane: ArrayList<mSubTOP>): RecyclerView.Adapter<adapter_sub.ViewHolder>() {

}

class adapter_sub(val Datane: ArrayList<mSubTOP>): RecyclerView.Adapter<adapter_sub.ViewHolder>() {

    override fun onBindViewHolder(holder: adapter_sub.ViewHolder, position: Int) {
        val location = Datane[position]
        holder.tvName?.text = location.warna
        holder.tvHobi?.text = location.jenis

    }

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): adapter_sub.ViewHolder {
        val v = LayoutInflater.from(parent.context).inflate(R.layout.layout_sub, parent, false)
        return ViewHolder(v)
    }

    override fun getItemCount(): Int {
        return Datane.size
    }

    class ViewHolder(itemView: View): RecyclerView.ViewHolder(itemView) {
        val tvName = itemView.findViewById<TextView>(R.id.tvJenis)
        val tvHobi = itemView.findViewById<TextView>(R.id.tvWarna)
    }
}

class adapter\u sub（val-Datane:ArrayList）：RecyclerView.adapter（）{
覆盖BindViewHolder（支架：适配器\子视图支架，位置：Int）{
val位置=数据元[位置]
holder.tvName？.text=location.warna
holder.tvHobi？.text=location.jenis
}
override fun onCreateViewHolder（父级：ViewGroup，viewType:Int）：适配器\子组件ViewHolder{
val v=LayoutFlater.from（parent.context）。充气（R.layout.layout_sub，parent，false）
返回视窗支架（v）
}
重写getItemCount（）：Int{
返回Datane.size
}
类ViewHolder（itemView:View）：RecyclerView.ViewHolder（itemView）{
val tvName=itemView.findviewbyd（R.id.tvJenis）
val tvHobi=itemView.findviewbyd（R.id.tvWarna）
}
}

好的，谢谢，你的建议消除了错误。但是如果您想看到“二进制XML文件行#14：二进制XML文件行#14：错误膨胀类文本视图”，请执行一个新错误。您可以将布局附加到问题上吗？布局看起来正常。你能附上你的错误的堆栈跟踪吗？这真的很奇怪。从我的观点来看，一切看起来都不错。您可以尝试从layout_sub.xml
中的第一个TextView
中删除一些属性，以找出导致崩溃的确切原因。你是对的。我删除了第一个文本视图，一切正常。非常感谢你的帮助。
