Tutorial Membuat Aplikasi Berita Indonesia dengan Android Studio
Tutorial Membuat Aplikasi Berita Indonesia Android

السَّلاَمُ عَلَيْكُمْ وَرَحْمَةُ اللهِ وَبَرَكَاتُه sobat 48😁. Bagaimana kabarnya? Semoga selalu dalam keadaan sehat ya. Kali ini saya akan membagikan sebuah artikel lagi yang membahas tentang Tutorial Membuat Aplikasi Berita Indonesia dengan Android Studio. Data aplikasi berita ini saya ambil dari API News API. API ini bersifat publik dan gratis (ada kuotanya jika gratis).

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

Fitur :

  • 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

Menurut saya aplikasi ini bisa dijadikan bahan untuk skripsi😄. Jika kalian ingin SOURCE CODE sample aplikasi ini, silahkan download di GITHUB saya DISINI. Tetapi jika kalian ingin tahu cara mengaplikasikannya, silahkan lanjut baca artikel ini sampai selesai.

Untuk kalian yang ingin mencoba tutorial aplikasi ini dengan versi video, berikut saya berikan Videonya:

Jangan lupa subscribe Channel Youtube saya juga ya , 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;

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”)) {

} 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) {
Intent intent = new Intent(MainActivity.this, BusinessActivity.class);
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 :

getMenuInflater().inflate(R.menu.menu_open_news, menu);
return super.onCreateOptionsMenu(menu);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == R.id.share) {//share news
shareUrl(url);
}
return super.onOptionsItemSelected(item);
}

//back pressed
@Override
public void onBackPressed() {
if (mWebView.canGoBack()) {
mWebView.goBack();
} else {
super.onBackPressed();
}
}

//setup toolbar
private void setupToolbar() {
Toolbar toolbar = findViewById(R.id.tbOpenNews);
setSupportActionBar(toolbar);

share.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
share.putExtra(Intent.EXTRA_TEXT, url);
startActivity(Intent.createChooser(share, “Bagikan ke : “));
}
}

 


<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

</LinearLayout>

</RelativeLayout>

</com.google.android.material.card.MaterialCardView>

</LinearLayout>

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 static String GET_CATEGORY_SPORTS = “https://newsapi.org/v2/top-headlines?country=id&category=sports&apiKey=f3aa09e2f1d7494e9fded68f30d4e4c1”;
public static String GET_CATEGORY_TECHNOLOGY = “https://newsapi.org/v2/top-headlines?country=id&category=technology&apiKey=f3aa09e2f1d7494e9fded68f30d4e4c1”;

}

15. Untuk holdernya, buat Class NewsViewHolder.java :


package com.azhar.indonews.holder;

import android.view.View;
import android.widget.ImageView;
import android.widget.TextView;

import androidx.recyclerview.widget.RecyclerView;

import com.azhar.indonews.R;
import com.google.android.material.card.MaterialCardView;

/**
* Created by Azhar Rivaldi on 22-12-2019.
*/
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;

/**
* Created by Azhar Rivaldi on 22-12-2019.
*/
public class ModelNews {

private String title;
private String publishedAt;
private String url;
private String urlToImage;

public void setTitle(String title) {
this.title = title;
}

public void setPublishedAt(String publishedAt) {
this.publishedAt = publishedAt;
}

public void setUrl(String url) {
this.url = url;
}

public void setUrlToImage(String urlToImage) {
this.urlToImage = urlToImage;
}

public String getTitle() {
return title;
}

public String getPublishedAt() {
return publishedAt;
}

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”, “-“)

.split(“-“);

int year_a = Integer.parseInt(date[0]);
int month_a = Integer.parseInt(date[1]);
int day_a = Integer.parseInt(date[2]);
int hour_a = Integer.parseInt(getHour(date[3]));
int minute_a = Integer.parseInt(date[4]);
//calendar a / time a (last time / published at )
Calendar cal_a = Calendar.getInstance();
cal_a.set(year_a, month_a, day_a, hour_a, minute_a);

//calendar b / time b (time now)
Calendar cal_b = Calendar.getInstance();
int year_b = cal_b.get(Calendar.YEAR);
int month_b = cal_b.get(Calendar.MONTH) + 1;
int day_b = cal_b.get(Calendar.DAY_OF_MONTH);
int hour_b = cal_b.get(Calendar.HOUR_OF_DAY);
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);
if (selisih_menit > 0) {
if (selisih_menit > 60 && selisih_menit < 1440) {
int jam = selisih_menit / 60;
timeAgo = jam + ” jam yang lalu”;
} else if (selisih_menit > 1440) {
int hari = selisih_menit / 1440;
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”;
