英文:
When parsing JSONArray comes last in the list of Retrofit?
问题
I get json request through GET
{ "data": [
"Черногория",
"Чехия",
"Чили"
]}
How to parse it if you need to display each country in a separate item. I'm using Pojo.
@SerializedName("data")
@Expose
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
public void onResponse(Call<Countries> call, Response<Countries> response) {
if (response.code() == 200) {
Countries countries = response.body();
if (countries != null) {
for (int x = 0; x < countries.getData().size(); x++) {
arrayList.add(countries);
viewAdapterCountry.notifyDataSetChanged();
}
}
}
}
this adapter
private ArrayList<Countries> countryModels;
Countries countryModel = countryModels.get(i);
List<String> country = countryModel.getData();
for (int x = 0; x < country.size(); x++) {
viewHolder.button.setText(country.get(x));
}

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