我想从API检索用户详细信息，但是当我将文本放在textview中时，它变成空白。

我的对象类

public class Obj {

我想在不同的文本视图中显示详细信息（例如名称，id，车牌号等）。但是它返回一个空字符串，即null。

Here's my API in JSON format

有人可以帮我吗？

答案 0 :(得分：1)

尝试这种接口方法。

   @GET("user_login_v1")
   Call<Obj> getUserDetails(@Query("email") String email,
                                             @Query("password") String password);

和MainActivity中的Call方法是这样的。 

 Call<Obj> call=login.getUserDetails(email,password);//email and password which user enter when he login in your device.
