Question

{
   "success":true,
   "userobject":{
       "username":"user",
       "email":"user@gmail.com",
       "password":"user123"
    }
}

这是我的JSON。我想从中创建POJO类。现在我有这样的事情：

public class LoginResponse
{
    @SerializedName("success")
    @Expose
    private Boolean success;

    @SerializedName("username")
    @Expose
    private String username;

    @SerializedName("email")
    @Expose
    private String email;

    @SerializedName("password")
    @Expose
    private String password;

    public Boolean getSuccess() {
        return success;
    }

    public String getUsername() {
        return username;
    }

    public String getEmail() {
        return email;
    }

    public String getPassword() {
        return password;
    }
}

我希望访问＆＃34;用户名＆＃34;，＆＃34;电子邮件＆＃34;，＆＃34;密码＆＃34;等字段。在Retrofit Callback中：

 final LoginRequest loginRequest = new LoginRequest(email, password);
        Call<LoginResponse> call = service.login(loginRequest);

        call.enqueue(new Callback<LoginResponse>() {
            @Override
            public void onResponse(Call<LoginResponse> call, Response<LoginResponse> response)
            {
                if(response.isSuccessful()) {
                    background.setImageResource(R.drawable.bg_login_screen);
                    progressBar.setVisibility(View.GONE);

                    Toast.makeText(LoginActivity.this, response.body().getEmail(), Toast.LENGTH_SHORT).show();
                }

它不起作用。我可以访问＆＃34;成功＆＃34;当然只有领域。 POJO课程应该如何？

Answer 1

userObject是一个新对象，您应该创建一个新类来访问它：

public class LoginResponse {
    @SerializedName("success")
    @Expose
    private Boolean success;

    private UserObject userobject;


    public Boolean getSuccess() {
        return success;
    }

    public UserObject getUserObject() {
       return userobject;
    }
}

和

public class UserObject {
    @SerializedName("username")
    @Expose
    private String username;

    @SerializedName("email")
    @Expose
    private String email;

    @SerializedName("password")
    @Expose
    private String password;

    public String getUsername() {
        return username;
    }

    public String getEmail() {
        return email;
    }

    public String getPassword() {
        return password;
    }
}

来自JSON的POJO类用于Retrofit2回调
