这是我的登录界面

package com.example.hb.loginapi;

import java.util.List;

   import retrofit2.Call;
   import retrofit2.http.GET;

  import retrofit2.http.POST;

   import retrofit2.http.Query;

    interface Login {

   @POST("user_login_v1")
   Call<ResObj>  loginInfo(@Query("password") String password, 
   @Query("email") String email);


   @GET("user_login_v1")
   Call<List> getUserDetails();


}

这是我的 ResObj 类

Here's my ResObj class

package com.example.hb.loginapi;

我的 MainActivity.java

My MainActivity.java

public class MainActivity extends AppCompatActivity {

List emList=new ArrayList();

List dataList=new ArrayList();

List userDets=new ArrayList();

ImageView proImg;
TextView userName;
TextView userID;
TextView userEmail;
TextView userStatus;
TextView userPlateNum;
TextView userStateName;
TextView userStateID;
TextView userSearchReportCount;

String img;
String name;
String idUser;
String emailID;
String status;
String plateNum;
String stateName;
String stateID;
String searchReportCount;

String email;

Login login;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    emList.add(email);

    userName=findViewById(R.id.userName);


    email=getIntent().getStringExtra("email");

     login=ApiUtils.getLoginClass();

    getUserData();
}


private void getUserData(){
    Call<List> call=login.getUserDetails();

    call.enqueue(new Callback() {
        @Override
        public void onResponse(Call call, Response response) {
            if(response.isSuccessful()){
                List resObj=(List)response.body();


                for(int i=0;i<resObj.size();i++){
                    Log.e("data",resObj.get(i).toString());
                }
 }
        }


        @Override
        public void onFailure(Call call, Throwable t) {
            Toast.makeText(getApplicationContext(),t.getMessage(),Toast.LENGTH_LONG).show();
        }
    });
}

}

我不知道在 onResponse() 方法中写什么.

I don't know what to write in the onResponse() method.

推荐答案

使用 Android studio 插件GsonFormat"创建 ResObj.class它将为您的 APICall 创建一个完美的 POJO 类，只是通过 Postman 的 API GET 响应.它将创建一个合适的 POJO 类，您可以从中简单地调用

Create ResObj.class using Android studio plugin "GsonFormat" It will create a perfect POJO class for your APICall, just past the API GET response from Postman. It will create a suitable POJO class, from which you can simply call

 private void callApi() {
    Log.e(TAG, "callApi: inside apiCall");
    Call<List> call = 
 login.getUserDetails();

 call.enqueue(new Callback<List>() {
        @Override
        public void onResponse(Call<List> call, @NonNull Response<List>response) {
            List items = response.body();

            items = list.data;
            String user_id = items.getUserID();
        }

        @Override
        public void onFailure(Call<LiveMatches> call, Throwable t) {

        }

在想要获取数据的地方调用 callApi() 方法；如果您复制并粘贴它，则此方法和方法将不起作用，您需要根据您的 POJO 类对其进行更改，但这将提供帮助还要添加您的布局和活动代码以提供上下文

call callApi() method where you want to get data; This method and method will not work if you copy and paste it you need to alter it according to your POJO class but this will provide help Also add your layout and activity code to give us context
