api를 이용하여 영화 정보 가져오기

0. 응용한 기술

- 이미지 또한 api를 가져와서 영화 이미지를 구현해본다.

( 여기서는 대충 아무 인터넷에 있는 자료를 가져와본다. )

1. 구현해야 할 것

2. 제약조건

- api 주소는 아래에 있는 사이트 주소로 이용한다.

3. java 소스코드

( 아래는 MainActivity.java의 코드이다. )

import androidx.appcompat.app.AppCompatActivity;
import androidx.recyclerview.widget.LinearLayoutManager;
import androidx.recyclerview.widget.RecyclerView;

import android.database.sqlite.SQLiteDatabase;

public class MainActivity extends AppCompatActivity {
    EditText ed1;
    Button btn1;

    RequestQueue requestQueue;

    RecyclerView recyclerView;
    MovieAdapter movieAdapter;

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

        ed1 = findViewById(R.id.editText);

        btn1 = findViewById(R.id.button);
        btn1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                String url = ed1.getText().toString();
                makeRequest(url);
            }
        });

        if(requestQueue == null){
            requestQueue = Volley.newRequestQueue(getApplicationContext());
        }

        recyclerView = findViewById(R.id.recyclerView);
        LinearLayoutManager layoutManager = new LinearLayoutManager(this, LinearLayoutManager.VERTICAL,
                false);
        recyclerView.setLayoutManager(layoutManager);

        movieAdapter = new MovieAdapter();
        recyclerView.setAdapter(movieAdapter);
    }

    private void makeRequest(String url) {
        StringRequest request = new StringRequest(Request.Method.GET, url,
                new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {
                        processResponse(response);
                    }
                }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
            }
        });
        request.setShouldCache(false);
        requestQueue.add(request);
    }

    private void processResponse(String response) {
        Gson gson = new Gson();
        MovieList movieList = gson.fromJson(response, MovieList.class);
        int movieSize = movieList.boxOfficeResult.dailyBoxOfficeList.size();

        for(int i=0; i<movieSize; i++){
            Movie movie = movieList.boxOfficeResult.dailyBoxOfficeList.get(i);

            movieAdapter.addItem(movie);
        }

        movieAdapter.notifyDataSetChanged();
    }
}

( 아래는 MovieList, MovieListResult, Movie의 클래스이다. )

( api 주소마다 속성값이 틀리므로, 변수의 이름을 주의해야 한다. )

( 아래는 MovieAdapter.class 이다. )

import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;

import androidx.annotation.NonNull;
import androidx.recyclerview.widget.RecyclerView;

import java.util.ArrayList;

public class MovieAdapter extends RecyclerView.Adapter<MovieAdapter.ViewHolder>{
    ArrayList<Movie> items = new ArrayList<>();

    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        LayoutInflater inflater = LayoutInflater.from(parent.getContext());
        View view = inflater.inflate(R.layout.movie_item, parent, false);

        return new ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
        Movie item = items.get(position);
        holder.setItem(item);
    }

    @Override
    public int getItemCount() {
        return items.size();
    }

    public void addItem(Movie movie) {
        items.add(movie);
    }

    public static class ViewHolder extends RecyclerView.ViewHolder{
        TextView tv1, tv2;

        public ViewHolder(@NonNull View itemView) {
            super(itemView);

            tv1 = itemView.findViewById(R.id.textView);
            tv2 = itemView.findViewById(R.id.textView2);
        }

        public void setItem(Movie item){
            tv1.setText(item.movieNm);
            tv2.setText(item.audiCnt + "명");
        }
    }
}

4. xml 소스코드

( 아래는 activity_main.xml의 코드이다. )

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <EditText
        android:id="@+id/editText"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:ems="10"
        android:inputType="text"
        />

    <Button
        android:id="@+id/button"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="요청하기" />

    <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/recyclerView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginBottom="10dp"/>

</LinearLayout>

                    android:textColor="#FF0000FF"
                    android:textSize="16sp" />
