我正在使用Wordpress，我想获得自定义字段，但我无法找到任何可以获得它们的内容，或者如果可以的话，我能找到的最接近的答案是{{3}但是我无法理解我如何能够对我有利，我在使用retrofit2时是新手。你能告诉我是否有可能这样做，如果是这样的话怎么样？ 以下是JSON回复我尝试使用

编辑3 How to get JSON ARRAY and JSON object response from retrofit response?
答案 0 :(得分：0)
使用Json to pojo scheme
这将为你的json
创建所有模型类在您的活动中
Call<ServerResponse> call = service.getdata();
call.enqueue(new Callback<ServerResponse>() {
@Override
public void onResponse(Call<ServerResponse> call, Response<ServerResponse> response) {
ServerResponse serverResponse = response.body();
if (serverResponse != null) {
List<Categories> categoriesList = response.getCategory();
}
}
@Override
public void onFailure(Call<ServerResponse> call, Throwable t) { } });
