When parsing JSONArray comes last in the list of Retrofit?

问题

I get json request through GET

  1. { "data": [
  2.     "Черногория",
  3.     "Чехия",
  4.     "Чили"
  5. ]}

How to parse it if you need to display each country in a separate item. I'm using Pojo.

  1. @SerializedName("data")
  2. @Expose
  3. private ArrayList<String> data = null;

this is an activity in which I use retrofit to connect, everything comes, but displays only the last field in the lists

  1. public void onResponse(Call<Countries> call, Response<Countries> response) {
  2.     if (response.code() == 200) {
  3.         Countries countries = response.body();
  4.         if (countries != null) {
  5.             for (int x = 0; x < countries.getData().size(); x++) {
  6.                 arrayList.add(countries);
  7.                 viewAdapterCountry.notifyDataSetChanged();
  8.             }
  9.         }
  10.     }
  11. }

this adapter

  1. private ArrayList<Countries> countryModels;
  2. Countries countryModel = countryModels.get(i);
  3. List<String> country = countryModel.getData();
  4. for (int x = 0; x < country.size(); x++) {
  5.     viewHolder.button.setText(country.get(x));
  6. }

得分: 1

我认为你一次性添加了所有数据，而不是逐个添加
arrayList.add(countries);你应该这样做 arrayList.add(countries.getData().get(x)); 然后在循环外部你应该写 viewAdapterCountry.notifyDataSetChanged();

在适配器的 bindViewHolder 方法中：

  1. override fun onBindViewHolder(holder: MyViewHolder, position: Int) {
  2.     val item = list?.get(position)
  4.     holder.button.setText(item)
  5. }
英文:

I think you are adding all the data at once instead of one by one
arrayList.add(countries);you should do arrayList.add(countries.getData().get(x)); then outside the loop you should write viewAdapterCountry.notifyDataSetChanged();

in bindivewholder of adapter

  1.     override fun onBindViewHolder(holder: MyViewHolder, position: Int) {
  2.         val item = list?.get(position)
  4.         holder.button.setText(item)
  5.      
  6.     }
