Aplikasi Movie & TV Show Menggunakan API TMDB (Part 2: Implementasi)

Tutorial ini adalah bagian ke-2 dari Aplikasi Movie & TV Shows Menggunakan API TMDB. Bagi Anda yang ingin mengikuti tutorial ini namun belum melihat tutorial bagian 1, silahkan untuk terlebih dahulu melihatnya, Klik Disini. Tutorial tersebut mengenai langkah-langkah mendapatkan API Key TMDB.

Sekarang mari kita buat sebuah project baru dengan minimum SDK 5.0 (21) dan layout  empty activity. Pada tutorial ini, aplikasi diberi nama Movie Tracker dengan nama package com.gwnbs.movietracker

Aplikasi ini akan memiliki fitur yakni menampilkan Most Popular Movies, Now Playing Movies, Upcoming Movies, Top Rated Movies, Most Popular TV Shows, Top Rated TV Shows, On The Air TV Shows, rincian dari movie / tv show, dan pencarian movie / tv show. Berikut video singkat penampakan dari aplikasi.



Disini kita menggunakan Java 8 atau 1.8, sehingga pada build.gradle(app) kita perlu melakukan konfigurasi tambahan. Baik, setelah project Anda sudah dibuat, pertama-tama buka file build.gradle(app) untuk melakukan konfigurasi dan menambahkan beberapa library yang dibutuhkan seperti : Retrofit, Picasso dan RoundedImageView. Pastikan file gradle Anda seperti dibawah ini :

build.gradle(:app) :
plugins {
id 'com.android.application'
}

android {
compileSdkVersion 30
buildToolsVersion "29.0.3"

defaultConfig {
applicationId "com.gwnbs.movietracker"
minSdkVersion 21
targetSdkVersion 30
versionCode 1
versionName "1.0"

testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}

buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}

dependencies {

//Library bawaan
implementation 'androidx.appcompat:appcompat:1.2.0'
implementation 'com.google.android.material:material:1.3.0'
implementation 'androidx.constraintlayout:constraintlayout:2.0.4'
testImplementation 'junit:junit:4.13.2'
androidTestImplementation 'androidx.test.ext:junit:1.1.2'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'

//Library tambahan yang dibutuhkan
implementation 'com.squareup.retrofit2:retrofit:2.9.0'
implementation 'com.squareup.retrofit2:converter-gson:2.9.0'
implementation 'com.squareup.picasso:picasso:2.71828'
implementation 'io.reactivex.rxjava2:rxandroid:2.0.1'
implementation 'com.makeramen:roundedimageview:2.3.0'
}




Setelah itu lakukan sync gradle untuk mulai mengunduh library. Berikutnya resouce value yaitu strings.xml, colors.xml dan themes.xml. Saya harap Anda sudah menggunakan Android Studio versi terbaru saat ini yaitu 4.1.2 agar terhindar dari kendala-kendala, karena cukup banyak perubahan pada versi terbaru ini.

Untuk versi lama, resource value themes.xml adalah styles.xml. Pada Android Studio terbaru saat Anda membuat sebuah project baru, themes.xml ada 2 tipe yaitu night dan light. Silahkan hapus saja yang tipe night karena disini kita tidak menggunakannya. Berikut ketiga resource value tersebut.

colors.xml :
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="purple_200">#FFBB86FC</color>
<color name="purple_500">#FF6200EE</color>
<color name="purple_700">#FF3700B3</color>
<color name="teal_200">#FF03DAC5</color>
<color name="teal_700">#FF018786</color>
<color name="black">#FF000000</color>
<color name="white">#FFFFFFFF</color>
<color name="color_actionbar">#E6E4E4</color>
</resources>

strings.xml :
<resources>
<string name="app_name">Movie Tracker | gwnbs.com</string>
<string name="movies">Movies</string>
<string name="most_popular_movies">Most Popular Movies</string>
<string name="now_playing_movies">Now Playing Movies</string>
<string name="upcoming_movies">Upcoming Movies</string>
<string name="top_rated_movies">Top Rated Movies</string>
<string name="tv_shows">TV Shows</string>
<string name="most_popular_tv_shows">Most Popular TV Shows</string>
<string name="top_rated_tv_shows">Top Rated TV Shows</string>
<string name="on_the_air_tv_shows">On The Air TV Shows</string>
<string name="text_info">Aplikasi ini sepenuhnya menggunakan API dari TMDB (www.themoviedb.org), namun tidak didukung oleh TMDB.</string>
<string name="enter_keyword">Enter query</string>
<string name="no_results">No results</string>
<string name="something_wrong">Something wrong with connection</string>
<string name="search_movie_or_tv_show">Search Movie or TV Show</string>
</resources>

themes.xml :
<resources xmlns:tools="http://schemas.android.com/tools">
<!-- Base application theme. -->
<style name="Theme.MovieTracker" parent="Theme.MaterialComponents.Light.NoActionBar">
<!-- Primary brand color. -->
<item name="colorPrimary">#454545</item>
<item name="colorPrimaryVariant">#4A4141</item>
<item name="colorOnPrimary">@color/white</item>
<!-- Secondary brand color. -->
<item name="colorSecondary">@color/teal_200</item>
<item name="colorSecondaryVariant">@color/teal_700</item>
<item name="colorOnSecondary">@color/black</item>
<!-- Status bar color. -->
<item name="android:statusBarColor" tools:targetApi="l">?attr/colorPrimaryVariant</item>
<item name="android:fontFamily">@font/alegreya_medium</item>
<!-- Customize your theme here. -->
</style>
</resources>


Pada themes.xml diatas, untuk item fontFamily, saya mengunduhnya dari fonts.google.com. Silahkan untuk memilih font Anda sendiri, atau Anda bisa menghapus item fontFamily pada themes.xml diatas jika Anda belum mau terlalu ribet.

Berikutnya icon drawable dan background drawable. Untuk background drawable kita memilik 5 files xml dan vector drawable kita memilik 3 icon xml. Berikut file nya.

bg_actionbar.xml :
<?xml version="1.0" encoding="utf-8"?>

Tahap selanjutnya, buatlah 2 buah files java, sebuah java class dan sebuah java interface yang digunakan untuk mengirim permintaan API dari TMDB. Beri nama ApiClient.java dan ApiService.java. Berikut isinya.

ApiClient.java :
package com.gwnbs.movietracker;

import retrofit2.Retrofit;
import retrofit2.converter.gson.GsonConverterFactory;

public class ApiClient {

private static Retrofit retrofit;

public static Retrofit getClient() {
if (retrofit == null) {
retrofit = new Retrofit.Builder()
.baseUrl("https://api.themoviedb.org/3/")
.addConverterFactory(GsonConverterFactory.create())
.build();
}
return retrofit;
}

}

ApiService.java :
package com.gwnbs.movietracker;

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

public interface ApiService {

//Permintaan untuk menampilkan Most Popular Movies
@GET("movie/popular")
Call<MovieRespon> getPopularMovies(@Query("api_key") String apiKey, @Query("language") String language,
@Query("page") int page);

//Permintaan untuk menampilkan Now Playing Movies
@GET("movie/now_playing")
Call<MovieRespon> getNowPlayingMovies(@Query("api_key") String apiKey, @Query("language") String language,
@Query("page") int page);

//Permintaan untuk menampilkan Upcoming Movies
@GET("movie/upcoming")
Call<MovieRespon> getUpcomingMovies(@Query("api_key") String apiKey, @Query("language") String language,
@Query("page") int page);

//Permintaan untuk menampilkan Top Rated Movies
@GET("movie/top_rated")
Call<MovieRespon> getTopRatedMovies(@Query("api_key") String apiKey, @Query("language") String language,
@Query("page") int page);

//Permintaan untuk pencarian Movie
@GET("search/movie")
Call<MovieRespon> searchMovie(@Query("api_key") String apiKey, @Query("language") String language,
@Query("query") String query, @Query("page") int page);

//Permintaan untuk menampilkan rincian / details movie
@GET("movie/{movie_id}")
Call<MovieDetails> getMovieDetails(@Path("movie_id") String id, @Query("api_key") String apiKey);

//Permintaan untuk menampilkan Most Popular TV Shows
@GET("tv/popular")
Call<TVRespon> getTvPopular(@Query("api_key") String apiKey, @Query("language") String language,
@Query("page") int page);

//Permintaan untuk menampilkan Top Rated TV Shows
@GET("tv/top_rated")
Call<TVRespon> getTvTopRated(@Query("api_key") String apiKey, @Query("language") String language,
@Query("page") int page);

//Permintaan untuk menampilkan On Air TV Shows
@GET("tv/on_the_air")
Call<TVRespon> getTvOnAir(@Query("api_key") String apiKey, @Query("language") String language,
@Query("page") int page);

//Permintaan untuk menampilkan rincian TV Show
@GET("tv/{tv_id}")
Call<TVDetails> getTvDetails(@Path("tv_id") String id, @Query("api_key") String apiKey);

//Permintaan untuk pencarian TV Shows
@GET("search/tv")
Call<TVRespon> searchTv(@Query("api_key") String apiKey, @Query("language") String language,
@Query("query") String query, @Query("page") int page);

}


Metode call-call diatas akan ditandai dengan error karena kita belum membuat class-class nya. Berikutnya buatlah beberapa java class, pertama buatlah sebuah class dengan nama ImageAdapter.java. Class ini berisi 2 metode static, digunakan untuk memuat poster dan backdrop gambar dari database TMDB ke aplikasi.

ImageAdapter.java :
package com.gwnbs.movietracker;

import android.widget.ImageView;

import com.squareup.picasso.Callback;
import com.squareup.picasso.Picasso;

public class ImageAdapter {

public static final String IMAGEBASE_URL = "https://image.tmdb.org/t/p/w220_and_h330_face";
public static final String BACKDROPIMAGE_BASE_URL = "https://image.tmdb.org/t/p/original";

public static void setPosterURL(ImageView imageView, String path) {
try {
imageView.setAlpha(0f);
Picasso.get().load(IMAGEBASE_URL + path).noFade().into(imageView, new Callback() {
@Override
public void onSuccess() {
imageView.animate().setDuration(500).alpha(1f).start();
}
@Override
public void onError(Exception e) {
}
});
} catch (Exception ignored) {
}
}

public static void setBackdropURL(ImageView imageView, String path) {
try {
imageView.setAlpha(0f);
Picasso.get().load(BACKDROPIMAGE_BASE_URL + path).noFade().into(imageView, new Callback() {
@Override
public void onSuccess() {
imageView.animate().setDuration(500).alpha(1f).start();
}
@Override
public void onError(Exception e) {
}
});
} catch (Exception ignored) {
}
}
}


Nah, sekarang buatlah 6 buah java files dengan nama : MovieRespon.java, MovieResult.java, MovieDetails.java, TVRespon.java, TVResult.java dan TVDetails.java. Class-class ini digunakan untuk getter (mendapatkan) nilai-nilai yang kita butuhkan dari database TMDB. Karena kita memuat data dengan streaming maka kita membutuhkan anotasi Serialize.

MovieRespon.java :
package com.gwnbs.movietracker;

import com.google.gson.annotations.SerializedName;

Tentu disini kita akan menggunakan RecyclerView untuk memuat item-item yang kita request dalam daftar. Disini kita akan membutuhkan 4 buah java class adapter yaitu untuk daftar movie, daftar tv show, pencarian movie dan pencarian tv show. Namun sebelumnya buatlah terlebih dahulu 2 buah layout resouce file sebagai container dari item. Beri nama item_container.xml dan item_container_search.xml. Berikut kedua files ini.

item_container.xml :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_height="wrap_content"
android:layout_margin="5dp"
android:background="@drawable/bg_item"
android:gravity="center"
android:orientation="vertical"
android:padding="3dp">

Sekarang 4 buah file java adapter. Beri nama MovieAdapter.java, MovieSearchAdapter.java, TVAdapter.java dan TVSearchAdapter.java. Ke-4 adapter ini adalah adapter RecyclerView karena memang disini kita hanya memakai RecyclerView. Untuk class list, RecyclerView adalah yang terbaik saat ini.

MovieAdapter.java :
package com.gwnbs.movietracker;

import android.content.Context;
import android.content.Intent;
import android.text.TextUtils;
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 com.makeramen.roundedimageview.RoundedImageView;

import java.util.List;

public class MovieAdapter extends RecyclerView.Adapter<MovieAdapter.MovieViewHolder> {

private final List<MovieResult> movieResults;
private final Context context;

public MovieAdapter(List<MovieResult> movieResults, Context context) {
this.movieResults = movieResults;
this.context = context;
}

@NonNull
@Override
public MovieAdapter.MovieViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
return new MovieViewHolder(LayoutInflater.from(parent.getContext())
.inflate(R.layout.item_container, parent, false));
}

@Override
public void onBindViewHolder(@NonNull MovieAdapter.MovieViewHolder holder, int position) {
holder.bindItem(movieResults.get(position), context);
}

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

static class MovieViewHolder extends RecyclerView.ViewHolder {

private final RoundedImageView imageItemPoster;
private final TextView textItemName;

MovieViewHolder(@NonNull View itemView) {
super(itemView);

imageItemPoster = itemView.findViewById(R.id.imageItemPoster);
textItemName = itemView.findViewById(R.id.textItemName);
}

void bindItem(MovieResult movieResult, Context context) {
if (!TextUtils.isEmpty(movieResult.getPosterPath())) {
ImageAdapter.setPosterURL(imageItemPoster, movieResult.getPosterPath());
} else {
imageItemPoster.setImageResource(R.drawable.ic_android);
}
textItemName.setText(movieResult.getTitle());

itemView.setOnClickListener(v -> {
Intent i = new Intent(context, DetailsActivity.class);
i.putExtra("tipe", "movie");
i.putExtra("id", movieResult.getId());
context.startActivity(i);
});
}
}
}

MovieSearchAdapter.java :
package com.gwnbs.movietracker;

import android.content.Context;
import android.content.Intent;
import android.text.TextUtils;
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 com.makeramen.roundedimageview.RoundedImageView;

private final Context context;

public MovieSearchAdapter(List<MovieResult> movieResults, Context context) {
this.movieResults = movieResults;
this.context = context;
}

@NonNull
@Override
public MovieSearchAdapter.MovieViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
return new MovieViewHolder(LayoutInflater.from(parent.getContext())
.inflate(R.layout.item_container_search, parent, false));
}

Anda akan mendapatkan error untuk class DetailsActivity.java karena activity nya belum kita buat, silahkan diabaikan saja. Selanjutnya kita akan implementasi di MainActivity, tentunya pertama-tama dengan mendesain layout activity_main.xml terlebih dahulu. Supaya view di activity_main.xml tidak terlalu banyak, xml untuk movie dan tv kita pisahkan dalam resource berbeda yang nantinya kita include ke activity_main.xml.

Baik, buatlah terlebih dahulu 2 layout resource files, berikan nama layout_movie.xml dan layout_tv.xml dan berikut isinya :

layout_movie.xml :
