我如何获取json数据并在微调框中显示？我想在微调器中显示状态名称和代码这是我的活动

下面是我正在获得州名和州代码的邮递员图像所以现在我如何获得并在微调器中显示请帮助我

String country_id = "in";

    Call<ResponseBody> call = SignupClient
            .getInstance()
            .getApi()
            .users(country_id);

    call.enqueue(new Callback<ResponseBody>() {
        @Override
        public void onResponse(Call<ResponseBody> call, Response<ResponseBody> response) {



        }

        @Override
        public void onFailure(Call<ResponseBody> call, Throwable t) {
            Toast.makeText(SignupActivity.this, t.getMessage(), Toast.LENGTH_SHORT).show();
        }
    });

这是我的Java类

public class SignupClient {

private static final String BASE_URL = "http://74.207.233.160/";
private static SignupClient mInstance;
private Retrofit retrofit;

private SignupClient() {
    retrofit = new Retrofit.Builder()
            .baseUrl(BASE_URL)
            .addConverterFactory(GsonConverterFactory.create())
            .build();
}

public static synchronized SignupClient getInstance() {
    if (mInstance == null)
    {
        mInstance = new SignupClient();
    }
    return mInstance;
}

public SignupApi getApi() {
    return retrofit.create(SignupApi.class);
}
}

这是我的Api

public interface SignupApi {

@FormUrlEncoded
@POST("find_states")
Call<ResponseBody> users(
        @Field("country_id") String country_id
);
}

尝试以下操作：（用您的Pojo类名称替换“ FilterTable”）

class CustomArrayAdapterForSpinner(private val filterValues: List<FilterTable>) : BaseAdapter() {
private val inflater: LayoutInflater
var name: String? = null

val count: Int
    @Override
    get() = filterValues.size()

init {
    inflater = getContext()
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE) as LayoutInflater
}

@Override
fun getItem(position: Int): Object {
    return filterValues[position]
}

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

@Override
fun getView(position: Int, view: View, parent: ViewGroup): View {
    val holder: Holder
    var convertView = view
    if (convertView !=null) {
        holder = convertView.getTag()
    } else {
        holder = Holder()
        convertView = inflater.inflate(R.layout.row_filter, null)
        holder.chkTextView = convertView.findViewById(R.id.checkTxt)
        convertView.setTag(holder)
    }
    holder.chkTextView!!.setText(filterValues[position].getName())
    holder.chkTextView!!.setTag(if (filterValues[position].isSelection()) "unChecked" else "checked")
    return convertView
}

fun setSelection(str: String) {
    for (model in filterValues)
        model.setSelection(model.getName().equals(str))
}

internal inner class Holder {
    var chkTextView: CheckedTextView? = null
}

}
