| Tutorial Membuat Aplikasi Berita Indonesia Android |
Pada sampel aplikasi berita ini, saya menyematkan beberapa topik berita antara lain :
- Berita Utama / Headlines
- Berita Olahraga
- Berita Teknologi
- Berita Bisnis
- Berita Kesehatan
- dan Berita Hiburan
- Menggunakan API dari News API https://newsapi.org/
- Menggunakan Fast Android Networking untuk Rest API
- Menggunakan Glide untuk menampilkan gambar
- Menggunakan Webview untuk View Berita
Untuk kalian yang ingin mencoba tutorial aplikasi ini dengan versi video, berikut saya berikan Videonya:
Jangan lupa subscribe Channel Youtube saya juga ya Azhar Rivaldi, karena disana ada banyak tutorial-tutorial untuk membuat aplikasi lainnya. Oke langsung saja tanpa basa-basi lagi kita langsung ke langkah pertama :
1. Buat project baru di Android Studio dengan cara klik File ⇒ Project Baru. Ketika diminta untuk memilih Default Activity, pilih Empty Activity dan klik next. Untuk minSDK, disini saya set API 21 ya.
2. Tambahkan beberapa library di build.gradle :
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'com.google.android.material:material:1.0.0'
implementation 'androidx.cardview:cardview:1.0.0'
implementation 'androidx.recyclerview:recyclerview:1.1.0'
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test:runner:1.2.0'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'
implementation 'com.github.bumptech.glide:glide:4.11.0'
annotationProcessor 'com.github.bumptech.glide:compiler:4.11.0'
implementation 'com.amitshekhar.android:android-networking:1.0.2'
}
3. Ubah AndroidManifest.xml menjadi seperti ini :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.azhar.indonews">
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme"
android:usesCleartextTraffic="true"
tools:ignore="AllowBackup,GoogleAppIndexingWarning,UnusedAttribute">
<activity android:name=".activities.MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".activities.EntertaimentActivity"
android:screenOrientation="portrait" />
<activity
android:name=".activities.HealthActivity"
android:screenOrientation="portrait" />
<activity
android:name=".activities.BusinessActivity"
android:screenOrientation="portrait" />
<activity
android:name=".activities.TechnologyActivity"
android:screenOrientation="portrait" />
<activity
android:name=".activities.HeadLineActivity"
android:screenOrientation="portrait" />
<activity
android:name=".activities.SportsNewsActivity"
android:screenOrientation="portrait" />
<activity
android:name=".activities.OpenNewsActivity"
android:screenOrientation="portrait" />
</application>
</manifest>
4. Ubah MainActivity.java menjadi seperti ini :
package com.azhar.indonews.activities;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
import android.text.format.DateFormat;
import android.view.View;

public class MainActivity extends AppCompatActivity implements View.OnClickListener {
MaterialCardView cvHead, cvSports, cvTechno, cvBusiness, cvHealth, cvEntertaiment;
TextView tvToday;
String hariIni;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
cvHead = findViewById(R.id.cardHeadLine);
cvSports = findViewById(R.id.cardSports);
cvTechno = findViewById(R.id.cardTechno);
cvBusiness = findViewById(R.id.cardBusiness);
cvHealth = findViewById(R.id.cardHealth);
cvEntertaiment = findViewById(R.id.cardEnter);
cvHead.setOnClickListener(this);
cvSports.setOnClickListener(this);
cvTechno.setOnClickListener(this);
cvBusiness.setOnClickListener(this);
cvHealth.setOnClickListener(this);
cvEntertaiment.setOnClickListener(this);
tvToday = findViewById(R.id.tvDate);
Date dateNow = Calendar.getInstance().getTime();
hariIni = (String) DateFormat.format("EEEE", dateNow);
if (hariIni.equalsIgnoreCase("sunday")) {
hariIni = "Minggu";
} else if (hariIni.equalsIgnoreCase("monday")) {
hariIni = "Senin";
} else if (hariIni.equalsIgnoreCase("tuesday")) {
hariIni = "Selasa";
} else if (hariIni.equalsIgnoreCase("wednesday")) {
hariIni = "Rabu";
} else if (hariIni.equalsIgnoreCase("thursday")) {
hariIni = "Kamis";
} else if (hariIni.equalsIgnoreCase("friday")) {
hariIni = "Jumat";
} else if (hariIni.equalsIgnoreCase("saturday")) {
hariIni = "Sabtu";
}
getToday();
}
private void getToday() {
Date date = Calendar.getInstance().getTime();
String tanggal = (String) DateFormat.format("d", date);
String monthNumber = (String) DateFormat.format("M", date);
String year = (String) DateFormat.format("yyyy", date);
int month = Integer.parseInt(monthNumber);
String bulan = null;
if (month == 1) {
bulan = "Januari";
} else if (month == 2) {
bulan = "Februari";
} else if (month == 3) {
bulan = "Maret";
} else if (month == 4) {
bulan = "April";
} else if (month == 5) {
bulan = "Mei";
} else if (month == 6) {
bulan = "Juni";
} else if (month == 7) {
bulan = "Juli";
} else if (month == 8) {
bulan = "Agustus";
} else if (month == 9) {
bulan = "September";
} else if (month == 10) {
bulan = "Oktober";
} else if (month == 11) {
bulan = "November";
} else if (month == 12) {
bulan = "Desember";
}
String formatFix = hariIni + ", " + tanggal + " " + bulan + " " + year;
tvToday.setText(formatFix);
}
@Override
public void onClick(View v) {
if (v.getId() == R.id.cardHeadLine) {
Intent intent = new Intent(MainActivity.this, HeadLineActivity.class);
startActivity(intent);
} else if (v.getId() == R.id.cardSports) {
Intent intent = new Intent(MainActivity.this, SportsNewsActivity.class);
startActivity(intent);
} else if (v.getId() == R.id.cardTechno) {
Intent intent = new Intent(MainActivity.this, TechnologyActivity.class);
startActivity(intent);
} else if (v.getId() == R.id.cardBusiness) {

startActivity(intent);
} else if (v.getId() == R.id.cardHealth) {
Intent intent = new Intent(MainActivity.this, HealthActivity.class);
startActivity(intent);
} else if (v.getId() == R.id.cardEnter) {
Intent intent = new Intent(MainActivity.this, EntertaimentActivity.class);
startActivity(intent);
}
}
}
5. Untuk tampilan menu utama, buat activity_main.xml dan item_main_grid.xml :
<?xml version="1.0" encoding="utf-8"?>

14. Buat Class NewsApi.java untuk API-nya :
package com.azhar.indonews.api;
public class NewsApi {
public static String GET_TOP_HEADLINES = "https://newsapi.org/v2/top-headlines?country=id&apiKey=f3aa09e2f1d7494e9fded68f30d4e4c1";

*/
public class NewsViewHolder extends RecyclerView.ViewHolder {
public ImageView image;
public TextView title;
public TextView publishedAt;
public MaterialCardView cvNews;
public View view;
public NewsViewHolder(View view) {
super(view);
cvNews = view.findViewById(R.id.cvNews);
image = view.findViewById(R.id.image);
title = view.findViewById(R.id.title);
publishedAt = view.findViewById(R.id.publishedAt);
this.view = view;
}
}
16. Untuk modelnya, buat Class ModelNews.java :
package com.azhar.indonews.model;
/**

}
public String getUrl() {
return url;
}
public String getUrlToImage() {
return urlToImage;
}
}
17. Terakhir, buat Class TimeUnits.java untuk konvert waktu berita dari API :
package com.azhar.indonews.utils;
import java.util.Calendar;
public class TimeUnits {
//convert timestamp to time ago
public static String getTimeAgo(String timeStamp) {
String timeAgo = "";
String[] date = timeStamp.replace("T", "-")

int minute_b = cal_b.get(Calendar.MINUTE);
cal_b.set(year_b, month_b, day_b, hour_b, minute_b);
final long MILIDETIK_SATU_MENIT = 60 * 1000;
long wA = cal_a.getTimeInMillis();
long wB = cal_b.getTimeInMillis();
//selisih
long selisih = wB - wA;
int selisih_menit = (int) (selisih / MILIDETIK_SATU_MENIT);

timeAgo = hari + " hari yang lalu";
} else {
timeAgo = selisih_menit + " menit yang lalu";
}
}
return timeAgo;
}
public static String getHour(String hour) {
String result = "";
if (hour.equals("00")) {
result = "07";
