我實施的改型2接口解析JSON元素（視頻的URL，縮略圖，標題等）Retrofit 2（在Android中）實現後，我的JSON元素在哪裏？
JSONschema2Pojo導致4個POJO類，但主要的/根之一是VideoInfo（從未頭腦實現Parcelable，我我還沒有做任何事情） 缺少@SerializedName("....")影響任何東西，知道這是由jsonschema2pojo自動生成的？更新：生成新的Pojo類，這次與Gson註釋(@SerializedName("") and @Expose)但仍然有相同的問題。
import android.os.Parcel;
import android.os.Parcelable;
import java.util.ArrayList;
import java.util.List;
public class VideoInfo implements Parcelable {
private List<Item> items = new ArrayList<Item>();
private int pageNumber;
private int pageSize;
private int totalCount;
/**
* No args constructor for use in serialization
*
*/
public VideoInfo() {
}
/**
*
* @param totalCount
* @param items
* @param pageSize
* @param pageNumber
*/
public VideoInfo(List<Item> items, int pageNumber, int pageSize, int totalCount) {
this.items = items;
this.pageNumber = pageNumber;
this.pageSize = pageSize;
this.totalCount = totalCount;
}
/**
*
* @return
* The items
*/
public List<Item> getItems() {
return items;
}
/**
*
* @param items
* The items
*/
public void setItems(List<Item> items) {
this.items = items;
}
/**
*
* @return
* The pageNumber
*/
public int getPageNumber() {
return pageNumber;
}
/**
*
* @param pageNumber
* The page_number
*/
public void setPageNumber(int pageNumber) {
this.pageNumber = pageNumber;
}
/**
*
* @return
* The pageSize
*/
public int getPageSize() {
return pageSize;
}
/**
*
* @param pageSize
* The page_size
*/
public void setPageSize(int pageSize) {
this.pageSize = pageSize;
}
/**
*
* @return
* The totalCount
*/
public int getTotalCount() {
return totalCount;
}
/**
*
* @param totalCount
* The total_count
*/
public void setTotalCount(int totalCount) {
this.totalCount = totalCount;
}
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
}
}
UPDATE：在類VideoInfo上面可以看到private List<Item> items = new ArrayList<Item>();這是因爲有這麼具有TIEMS列表另一個POJO類，如下所示：

我已經創建了改進接口VideoInterface.class
import retrofit2.Call; import retrofit2.http.GET;
/**
* retrofit 2 interface
*/
public interface VideoInterface {
String apiURL = ".....";
@GET(apiURL)
public Call<VideosResponse> listVideos();
}
我創建了一個響應/解析類VideosResponse.java
import com.google.gson.Gson;
import com.google.gson.GsonBuilder;
import java.util.ArrayList;
import java.util.List;
/**
*/
public class VideosResponse {
//initalizing the collection
List<VideoInfo> videos;
public VideosResponse() {
videos = new ArrayList<VideoInfo>();
}
//parsing the response
public static VideosResponse parseJSON(String response) {
Gson gson = new GsonBuilder().create();
VideosResponse videosResponse = gson.fromJson(response, VideosResponse.class);
return videosResponse;
}
}
修訂：最後我打電話的API，但沒有能夠得到各個元素 我知道我應該能夠做到像response.body().getItem().getID().getRendition().getUrl()例如，但我沒有看到它在自動完成，如果我寫它，我會得到錯誤。 此代碼是我onResume()方法，就是我註釋掉public static下面是因爲它不是onResume()
// Creating a simple REST adapter which points the API
// public static
final String BASE_URL = "http://api......";
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.build();
// Creating an instance of our API interface.
VideoInterface service = retrofit.create(VideoInterface.class);
Call<VideosResponse> call = service.listVideos();
call.enqueue(new Callback<VideosResponse>() {
@Override
public void onResponse(Call<VideosResponse> call, Response<VideosResponse> response) {
VideosResponse videoResponse = response.body();
}
@Override
public void onFailure(Call<VideosResponse> call, Throwable t) {
}});
一切到最後一步，似乎是正常的（沒有錯誤）內允許的原因，以下日誌給我：
Log.d("Videos ", response.message()); //OK
Log.d("Videos ", String.valueOf(response.isSuccess())); //TRUE
Log.d("Videos ", String.valueOf(response.code())); //200
但我仍然無法獲得我需要的字符串。當我打印響應的日誌顯示響應VideosResponse videoResponse = response.body();我得到：VideosResponse @ 3b8bfaa4，這是正常的嗎？我怎麼用這個？ 是否使用parcelable建議？它會改變什麼嗎？
你沒有在任何地方使用這個'VideosResponse videoResponse = response.body（）;'？ –
只是爲了記錄，不做任何事情 – ninjayoto
那麼你是如何讀取響應？ –
