Question

大家好，我试图显示jsonarray中的jsonarray的项目，但是如屏幕截图所示，它仅显示第一个数组，而不是全部，在我调试应用程序后，它会从所有数组中获取所有项目，但仅显示第一个请帮助！！！！

Json

{"results": [
{
  "name": "Bulbasaur",
  "number": "001",
  "info": [
    {
      "infoOne": "Grass",
      "infoTwo": "grass"
    },
    {
      "infoOne": "Poison",
      "infoTwo": "poison"
    }
  ]
},
{
  "name": "Ivysaur",
  "number": "002",
  "info": [
    {

适配器

class PokedexTypeAdapter(private val context: Context, private val pokemonDataLists: ArrayList<PokedexTypes>) :
RecyclerView.Adapter<PokedexTypeAdapter.TypeHolder>() {
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): TypeHolder {
    return PokedexTypeAdapter.TypeHolder(
        LayoutInflater.from(parent.context).inflate(
            R.layout.pokedex_type_card,
            parent,
            false
        )
    )
}

override fun getItemCount(): Int = pokemonDataLists.size

override fun onBindViewHolder(kantoHolder: TypeHolder, position: Int) {

    kantoHolder.displayHolder(pokemonDataLists[position])
}

class TypeHolder(itemView: View) :
    RecyclerView.ViewHolder(itemView) {

    var typeText: TextView? = null
    var typeImage: ImageView? = null;


    fun displayHolder(pokemonDataList: PokedexTypes) {

        typeText = itemView.findViewById(R.id.pokedex_info_two)
        typeImage = itemView.findViewById(R.id.pokedex_info_one)

        typeText?.text = pokemonDataList.typeText
        Picasso.get().load("http://www.gstyles.net/pokemonApp/pokemonDetails/${pokemonDataList.typeImage}.png").into(typeImage)
    }
}
}

AsyncTask

class PokedexTypeTask(
private val context: Context,
private val recyclerView: RecyclerView
) :
AsyncTask<String, Int, String>() {

private val httpRequest = HttpRequest()

override fun doInBackground(vararg strings: String): String? {
    return httpRequest.Request(strings[0])
}

override fun onPostExecute(s: String) {

    val mainObject: JSONObject
    val array: JSONArray
    var typeArray: JSONArray? = null
    val index = 2

    val pokemonTypeArrayList = ArrayList<PokedexTypes>()

    try {
        mainObject = JSONObject(s)
        array = mainObject.getJSONArray("results")

        for (i in 0 until array.length()) {
            val typeObject = array.getJSONObject(i)

            typeArray = typeObject.getJSONArray("info")

            for (t in 0 until typeArray.length()) {
                val infoObject = typeArray.getJSONObject(t)
                val infoOne = infoObject.getString("infoOne")
                val infoTwo = infoObject.getString("infoTwo")
                pokemonTypeArrayList.add(PokedexTypes(infoOne, infoTwo))
            }
        }

    } catch (e: JSONException) {
        e.printStackTrace()
    }

    when {
        typeArray!!.length() != 2 -> 1
    }

    recyclerView.layoutManager = GridLayoutManager(context, index)
    recyclerView.setHasFixedSize(true)
    recyclerView.adapter = PokedexTypeAdapter(context, pokemonTypeArrayList)
}
}

PokedexClass

class KantoDex : Fragment() {

override fun onCreateView(
    inflater: LayoutInflater, container: ViewGroup?,
    savedInstanceState: Bundle?
): View? {
    // Inflate the layout for this fragment
    val view: View = inflater.inflate(R.layout.fragment_dex, container, false)

    val mainJsonString = "http://www.gstyles.net/pokemonApp/pokedexJson/pokemonKantoJson.json"

    val dexRecycler: RecyclerView = view.findViewById(R.id.dex_list)

    PokedexTask(context!!, dexRecycler).execute(mainJsonString)

    val dexTitle = view.findViewById<TextView>(R.id.dex_title)
    val dexImage = view.findViewById<ImageView>(R.id.dex_img)

    dexTitle.text = context?.resources?.getString(R.string.kanto_items)
    dexImage.setImageResource(R.drawable.kanto)

    return view
 }
 }

RecyclerView仅显示JsonArray的第一项
