이용하는 개념 포스팅 :

안드로이드 스튜디오, JAVA] Retrofit2를 이용하여 데이터 통신하기

 

사용할 영화 API는 다음 페이지에서 가져온다.

https://yts.mx/api

API Documentation - YTS YIFY

먼저 모델을 만든다. 모델은 json으로 만들고 -> 만든 데이터를 확인하고 -> 다음 사이트를 참조하여 모델 클래스를 제작한다.

http://www.jsonschema2pojo.org/

 

먼저 값을 출력할 activity를 생성한다

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="8dp"
    tools:context=".MainActivity">

    <androidx.core.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <TextView
            android:id="@+id/text_view_result"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textColor="#000" />

안드로이드와 인터넷을 연결할 인터페이스를 만든다.

 

YtsPlaceHolderApi.java

package com.mary.retrofit2ex;

import java.util.List;
import java.util.Map;

import retrofit2.Call;
import retrofit2.http.GET;
import retrofit2.http.Query;
import retrofit2.http.QueryMap;

public interface YtsPlaceHolderApi {
    @GET("list_movies.json")
    Call<Yts> getYts(@QueryMap Map<String,String > queryString);
}

 

이 때. GET 뒤 어노테이션 속 값은 자원 url 뒤의 값을 입력한다.

 

마지막으로 소통할 자바 코드를 작성한다.
