我的改造电话有问题。我想获取一些数据，仅用于测试目的，看是否有任何东西，但是如您所见，什么也没有。我正在获取0、0.0，null之类的数据。

接口调用
@GET("3/discover/movie?api_key=APIKEY&with_genres=27")
Call<model> getABC();
改造电话
String url = "https://api.themoviedb.org/";
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(url)
.addConverterFactory(GsonConverterFactory.create())
.build();
apiCall api = retrofit.create(apiCall.class);
Call<model> call = api.getABC();
call.enqueue(new Callback<model>() {
@Override
public void onResponse(Call<model> call, Response<model> response) {
if (!response.isSuccessful()){
}
List<model> list = Collections.singletonList(response.body());
for (model model : list) {
String content = "";
content += model.getVote_count() + "\n";
content += model.getVote_average() + "\n";
content += model.getOverview() + "\n\n\n";
System.out.println(content);
}
}
@Override
public void onFailure(Call<model> call, Throwable t) {
}
});
}
POJO
public class model {
@SerializedName("vote_count")
private int vote_count;
@SerializedName("vote_average")
private double vote_average;
@SerializedName("overview")
private String overview;
public int getVote_count() {
return vote_count;
}
public double getVote_average() {
return vote_average;
}
public String getOverview() {
return overview;
}
我应该更改代码中的什么？我将不胜感激。我从通话中收到的代码是200-通话已成功完成，我的pojo类是否有东西？
*编辑的POJO
public class model {
@SerializedName("results")
@Expose
private List<movies> results;
public List<movies> getResults() {
return results;
}
class movies {
@SerializedName("vote_count")
@Expose
private Integer voteCount;
@SerializedName("vote_average")
@Expose
private Double voteAverage;
@SerializedName("overview")
@Expose
private String overview;
}
}
修改后的改装电话
public void onResponse(Call<model> call, Response<model> response) {
if (!response.isSuccessful()){
}
List<model> list = Collections.singletonList(response.body());
for (model model : list) {
System.out.println(model.getResults());
}
}
这是我收到的部分。
com.example.x.model$movies@5f6763b,
com.example.x.model$movies@e988158,
com.example.x.model$movies@6812b1,
为什么没有正确命名？
答案 0 :(得分：0)
您的Model类应如下所示：
public class Model {
@SerializedName("page")
private int page;
@SerializedName("results")
private List<Result> results;
@SerializedName("total_results")
private int total;
@SerializedName("total_pages")
private int totalPages;
//.......getter setter methods
}
public class Result{
@SerializedName("vote_count")
private int voteCount;
@SerializedName("vote_average")
private double voteAverage;
@SerializedName("overview")
private String overView;
//.....other fields
//......getter setter methods
}
然后，改造呼叫应如下所示：
Call<model> call = api.getABC();
call.enqueue(new Callback<Model>() {
@Override
public void onResponse(Call<Model> call, Response<Model> response) {
if (response.isSuccessful()) {
List<Result> results=response.body().getResults();
for(Result result:results){
Log.d(TAG,"Result: "+result.getVoteCount())
}
}
}
@Override
public void onFailure(Call<Model> call, Throwable t) {
}
});
快乐的编码。...：）

使用this网站在Java中生成正确的响应类
响应类如下所示：
public class BasicResponse implements Serializable
{
@SerializedName("page")
@Expose
private long page;
@SerializedName("total_results")
@Expose
private long totalResults;
@SerializedName("total_pages")
@Expose
private long totalPages;
@SerializedName("results")
@Expose
private List<Result> results = null;
private final static long serialVersionUID = 8749582078961182468L;
public long getPage() {
return page;
}
public void setPage(long page) {
this.page = page;
}
public long getTotalResults() {
return totalResults;

public void setTotalResults(long totalResults) {
this.totalResults = totalResults;

public List<Result> getResults() {

}
public void setResults(List<Result> results) {

您应检查的所有步骤：
java
public static UsersPOJO getOUsersPOJOJs(String value) {
Gson gson = new Gson();
JsonReader reader = new JsonReader(new StringReader(value));
reader.setLenient(true);
UsersPOJO data = new UsersPOJO.User();
try {
data = gson.fromJson(reader,UsersPOJOr.class);
}catch ( JsonSyntaxException e){
e.printStackTrace();
}
return data;
}
kotlin
fun getUsersPOJO getOUsersPOJOListJs(value: String) : UsersPOJO {
val gson = Gson()
val reader = JsonReader(StringReader(value))
reader.isLenient = true
var data = UsersPOJO()
try {
data = gson.fromJson<Options>(reader, UsersPOJO::class.java)
}catch (e: JsonSyntaxException){
e.printStackTrace()
}
return data
}
5.in onResponse 中的改装请求回调块，如果您期望得到json Array ，则称此方法
java
public static List<UserPOJO> getUserPOJOList(String value) {
Gson gson = new Gson();
Type listType = new TypeToken<List<UserPOJO>>() {}.getType();
List<UserPOJO> data = new ArrayList<UserPOJO>();
try {
data =new ArrayList<UserPOJO>(gson.fromJson(value,listType));
}catch ( JsonSyntaxException e){
e.printStackTrace();
}
return data;
}
kotlin
fun getUserPOJOList(value: String) : List<UserPOJO>{
val gson = Gson()
val listType = object : TypeToken<List<UserPOJO>>() {}.type
var data = ArrayList<UserPOJO>()
try {
data = gson.fromJson<List<UserPOJO>>(value, listType) as ArrayList<UserPOJO>
}catch (e: JsonSyntaxException){
e.printStackTrace()
}
return data
}
