这里是ApiInterface.java
public interface ApiInterface {

这里是调用方法&响应：
$ b $ pre $ ApiInterface apiService = ApiClient.getClient（）。create（ApiInterface.class）;
呼叫&SponsorsResult> call = apiService.getListOfSponsors（AppConstants.ASSEMBLY_BILL_ID，AppConstants.SESSION，AppConstants.FIELD）;

Log.d（TAG，赞助商数量：+ sponsors.size（））;
}
@Override
public void onFailure（Call< SponsorsResult> call，Throwable t）{
t.printStackTrace（）;
}
}）;
到目前为止，它失败&这里是logcat输出：
com.google.gson.JsonSyntaxException：java.lang.IllegalStateException：预期BEGIN_OBJECT，但是BEGIN_ARRAY在行1列2路径
无法执行响应。指导我解析这个回应。
@FormUrlEncoded

com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was BEGIN_ARRAY at line 1 column 2 path $
It fails to execute response . Guide me to parse this response.
解决方案
Please try to use this one
@FormUrlEncoded
@POST("api/sponsors")
Call<List<SponsorsResult>> getStatesAndDistrict(
@Field("xyz") String field1
);
Call <List<SponsorsResult>> call = service.getSponsorsValue();
call.enqueue(new Callback<List<SponsorsResult>>() {
@Override
public void onResponse(Call<List<SponsorsResult>> call, Response<List<SponsorsResult>> response) {
List<SponsorsResult> rs = response.body();
}
@Override
public void onFailure(Call<List<SponsorsResult>> call, Throwable t) {
}
});
class SponsorsResult {
@SerializedName("sponsors")
private List<SponsorsValue> sponsors;
public List<SponsorsValue> getSponsors() {
return sponsors;
}
}
class SponsorsValue{
@SerializedName("leg_id")
@Expose
private String legId;
@SerializedName("type")
@Expose
private String type;
@SerializedName("name")
@Expose
private String name;
public String getLegId() {
return legId;
}
public void setLegId(String legId) {
this.legId = legId;
}
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
