Android - Return 一本书的 ID 使用 Google BooksAPI

Android - Return a book's ID using Google BooksAPI

我正在使用 Google 书籍 API 通过搜索术语、查询来显示各种书籍的列表....

到目前为止一切正常,但有一个问题,我需要通过它的 id 得到一本书,我相信问题出在我的 BookResponse class

UPDATE 我想我应该在 BookItems class 中添加一个序列化 ID,但我不知道从那里去哪里

PS。下面你会发现每个 class 和一张显示 JSON 结构的图片

在 MainActivity 中搜索

ApiInterface apiService =
            RetrofitInstance.getRetrofitInstance().create(ApiInterface.class);

    retrofit2.Call<BookResponce> call = apiService.getBooksById("zyTCAlFPjgYC", BOOKS_API_KEY);
    call.enqueue(new Callback<BookResponce>() {
        @Override
        public void onResponse(retrofit2.Call<BookResponce> call, Response<BookResponce> response) {
            bookResp = response.body();
            for (int i = 0; i == 0; i++){
                bookList.add(i, bookResp.getBooks().get(i).getBookData());
            }

            cAdapter.notifyDataSetChanged();
        }

        @Override
        public void onFailure(retrofit2.Call<BookResponce> call, Throwable t) {
            Toast.makeText(this, "failed", Toast.LENGTH_LONG).show();
        }
    });

图书回复class

public class BookResponce {
    @SerializedName(value="items")
    ArrayList<BookItems> bookItems;

    @SerializedName(value="totalItems")
    int totalItems;

    public int getTotalItems() { return totalItems; }
    public ArrayList<BookItems> getBooks() { return bookItems; }
}

BookItems class

public class BookItems {
    //This is what I added
    @SerializedName(value = "id")
    String id;

    @SerializedName(value="volumeInfo")
    Book bookData;

    //and this...
    public String getId() {
        return id;
    }

    public Book getBookData(){return bookData; }
}

API 接口 class

public interface ApiInterface {

    @GET("volumes/{id}")
    Call<BookResponce> getBooksById(@Path("id") String bookId, 
        @Query("API_KEY") String apiKey);

    @GET("volumes")
    Call<BookResponce> getBooksByQuery(@Query("q") String query, 
        @Query("API_KEY") String apiKey, @Query("maxResults") int maxResults);
}

当您执行搜索时,在 bookList 中添加项目后只需添加:

bookList.get(i).setBookId(bookResp.getBooks().get(i).getId());

这是您案例中的完整示例:

ApiInterface apiService =
        RetrofitInstance.getRetrofitInstance().create(ApiInterface.class);

retrofit2.Call<BookResponce> call = apiService.getBooksById("zyTCAlFPjgYC", BOOKS_API_KEY);
call.enqueue(new Callback<BookResponce>() {
    @Override
    public void onResponse(retrofit2.Call<BookResponce> call, Response<BookResponce> response) {
        bookResp = response.body();
        for (int i = 0; i == 0; i++){
            bookList.add(i, bookResp.getBooks().get(i).getBookData());

            //This is what you must add
            bookList.get(i).setBookId(bookResp.getBooks().get(i).getId());
        }

        cAdapter.notifyDataSetChanged();
    }

    @Override
    public void onFailure(retrofit2.Call<BookResponce> call, Throwable t) {
        Toast.makeText(this, "failed", Toast.LENGTH_LONG).show();
    }
});
