Lisview inisde recyclerview仅显示第一个元素

Question

对不起，当我尝试将数据加载到Recyclerview内的Listview中时，我遇到了一些问题。

我获得了数据，并且已经将它们传递到Listview中，但是它只是显示了结果数据的第一个元素。

这是我的recyclerview的CostumViewholder

@Suppress("PLUGIN_WARNING")
class PengaduanViewHolder(val view: View, var aduan: Pengaduan? = null) : 
RecyclerView.ViewHolder(view), KomentarView {

private lateinit var presenter: KomentarPresenter
private var komentarList: MutableList<KomentarModel> = mutableListOf()
private lateinit var adapter: MyListAdapter

@RequiresApi(Build.VERSION_CODES.O)
@SuppressLint("SetTextI18n")
fun bindItem(aduan: Pengaduan) {
    val generator = ColorGenerator.MATERIAL
    Glide.with(view.context.applicationContext)
        .load(BuildConfig.BASE_URL + "assets/lapor/image/${aduan.lapor_image_1}")
        .into(view.iv_aduan_gambar)
    val jam = aduan.lapor_jam
    val tanggal = aduan.lapor_tanggal?.toDate()?.formatTo("EEEE, dd MMMM yyyy")
    view.tv_aduan_waktu.text = "$tanggal - $jam"
    view.tv_aduan_status.text = aduan.lapor_proses
    view.tv_aduan_lokasi.text = aduan.lapor_lokasi
    view.tv_aduan_lokasi.setOnClickListener {
        val browserIntent = Intent(Intent.ACTION_VIEW)
        browserIntent.data = Uri.parse("https://maps.google.com/?q=${aduan.lapor_lat},${aduan.lapor_long}")
        view.context.startActivity(browserIntent)
    }
    view.tv_aduan_deskripsi.text = aduan.lapor_deskripsi

    aduan.warga_namadepan?.let {
        it == "Unknown"
    }
    val letter = aduan.warga_namadepan?.substring(0, 1)
    Log.d("NAMA", letter)

    val color = generator.getColor(aduan.warga_id)
    var drawable: TextDrawable? = null
    val laporAnonim: String? = aduan.lapor_anonim
    when (laporAnonim) {
        null -> {
            drawable = TextDrawable.builder().buildRound("A", R.color.divider)
            view.tv_aduan_warga_nama.text = aduan.warga_namadepan
        }
        "Tidak" -> {
            drawable = TextDrawable.builder().buildRound(letter, color)
            view.tv_aduan_warga_nama.text = "${aduan.warga_namadepan} ${aduan.warga_namabelakang}"
        }
        "Ya" -> {

            view.tv_aduan_warga_nama.text = "Anonim"
        }
    }
    view.aduan_profil_image.setImageDrawable(drawable)
}

companion object {
    const val EXTRA_ADUAN_DETAIL = "EXTRA_ADUAN_DETAIL"
}

init {
    view.view_click.setOnClickListener {
        val intent = Intent(view.context, AduanDetailActivity::class.java)
        intent.putExtra(EXTRA_ADUAN_DETAIL, aduan)
        view.context.startActivity(intent)
    }

    view.ic_expand_less.setOnClickListener {

        view.progress_horizontal.visibility = View.VISIBLE
        view.ic_expand_less.visibility = View.GONE

        view.showComent.visibility = View.GONE
        view.hideComent.visibility = View.VISIBLE
        view.commentList.visibility = View.VISIBLE

        presenter = KomentarPresenter(this)
        val token = SharedPreferenceHelper(view.context).deviceToken

        Log.d("PENGADUAN_ADAPTER", token)
        adapter = MyListAdapter(view.context, komentarList)
        view.commentList.adapter = adapter
        adapter.notifyDataSetChanged()

        if (komentarList.size >= 1) {
            view.progress_horizontal.visibility = View.GONE
        } else {
            presenter.getKomentar(token, aduan?.lapor_id!!)
        }


    }
    view.ic_expand_more.setOnClickListener {
        view.progress_horizontal.visibility = View.GONE
        view.ic_expand_less.visibility = View.VISIBLE
        view.ic_expand_more.visibility = View.GONE

    }
}


override fun showData(response: KomentarResponse) {
    super.showData(response)
    if (response.success!!) {
        view.progress_horizontal.visibility = View.GONE
        komentarList.clear()
        komentarList.addAll(response.data!!)
        adapter.notifyDataSetChanged()
    }
}
}

这是我的ListAdapter外观

class MyListAdapter(private var context: Context?, private var item: List<KomentarModel>) : BaseAdapter() {


@SuppressLint("InflateParams")
override fun getView(position: Int, convertView: View?, parent: ViewGroup?): View {
    var crView = convertView
    val holder: ComentViewHolder
    if (crView == null) {
        holder = ComentViewHolder()
        val inflater = context?.getSystemService((Context.LAYOUT_INFLATER_SERVICE)) as LayoutInflater
        crView = inflater.inflate(R.layout.row_comment,null)
        crView.setPadding(0,10,0,10)
        holder.nama = crView?.findViewById(R.id.tv_nama_komentar) as TextView
        holder.isi = crView.findViewById(R.id.tv_isi_komentar) as TextView
        holder.tgl = crView.findViewById(R.id.tv_tgl_komentar) as TextView
        crView.tag = holder
    } else {
        holder = convertView?.tag as ComentViewHolder
    }
    val commnt = item[position]
    holder.nama?.text = commnt.nama
    holder.isi?.text = commnt.komentar
    holder.tgl?.text = commnt.komentar_waktu
    return crView

}

override fun getItem(position: Int): Any {
    return item[position]
}

override fun getItemId(position: Int): Long {
    return position.toLong()
}

override fun getCount(): Int {
    return item.size

private inner class ComentViewHolder {

recyclerview_list.xml在我的设计编辑器中是这样的

当我尝试运行我的应用时， 输出，就像这张图片：

任何人都可以帮助我，对不起我的英语不好。

Answer 1

您不必这样做。只需创建一个回收器视图，然后在其中创建一个方向为“垂直”而不是listView的LinearLayout。现在，在recyclerView的OnBindViewHolder中，只需运行一个循环，直到list.size（）并使用addView（）不断扩大linearLayout中的视图。在for循环之前，只需removeAllView（）。这将起作用，并且不会使滚动体验变差。
