Cara Membuat Aplikasi Android Pemesanan Travel Menggunakan Android Studio Dengan Database SQLite
maswijaba.my.id - Assalamualaikum wr.wb. Puji syukur kita bisa dipertemukan lagi di kesempatan kali ini, semoga semuanya sehat-sehat ya. Pada kesempatan kali ini saya akan membahas bagaimana Cara Membuat Aplikasi Android Pemesanan Travel Menggunakan Android Studio Dengan Database SQLite.
Tutorial sederhana ini dirasa bisa membantu kalian untuk membuat
aplikasi Android, walaupun tidak sempurna dan bisa dikatakan sederhana
mudah-mudahan bermanfaat untuk kalian yang ingin belajar tentang
Android.
Aplikasi ini di desain dengan sedemikian rupa dan pastinya untuk pemula sangat mudah untuk mempelajarinya. Aplikasi ini dibangun secara offline karena untuk datanya saya menggunakan database SQLite bukan menggunakan API seperti tutorial sebelumnya.
Aplikasi ini sangat disarankan untuk membuat tugas Android sebagai referensi kalian untuk tugas-tugas mobile, buat tugas akhir atau skripsi juga tidak apa-apa asalkan kalian memperbaharuinya (tambahkan yang belum ada).
Langsung saja kita masuk ke cara pengaplikasiannya dengan mengikuti step-step di bawah ini.
1. Buat Project Baru di Android Studio
Klik File - Project Baru. Ketika diminta untuk memilih Default Activity, kita memilih Empty Activity dan klik Next. (Untuk minSDK, saya set API 21)
2. Buat menu Login
Buat activity_login.xml dan LoginActivity.java dan isi scriptnya seperti dibawah ini
activity_login.xml

5. Buat menu untuk mem-Booking.
Sebagai contoh saya hanya menambahkan menu booking satu, jika kalian ingin menambahkan lebih dari satu tidak apa-apa. Buat activity_book_kereta.xml dan BookKeretaActivity.java lalu masukan skripnya.
activity_book_kereta.xml

7. Buat menu Profil
Untuk menampilkan profil yang akan memesan travel. Buat activity_profile.xml dan ProfileActivity.java
activity_profile.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="@drawable/bg_home_wave"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" />
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@+id/tbProfile">
<LinearLayout

</LinearLayout>
</ScrollView>
</RelativeLayout>
ProfileActivity.java
package com.wijaba.travel.activity;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;
import android.os.Bundle;
import android.view.MenuItem;
import android.widget.TextView;
import androidx.appcompat.app.AppCompatActivity;
import androidx.appcompat.widget.Toolbar;
import com.wijaba.travel.R;
import com.wijaba.travel.database.DatabaseHelper;
import com.wijaba.travel.session.SessionManager;
import java.util.HashMap;
public class ProfileActivity extends AppCompatActivity {
protected Cursor cursor;
DatabaseHelper dbHelper;
SQLiteDatabase db;
SessionManager session;
String name, email;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_profile);
dbHelper = new DatabaseHelper(this);
session = new SessionManager(getApplicationContext());
HashMap<String, String> user = session.getUserDetails();
email = user.get(SessionManager.KEY_EMAIL);
db = dbHelper.getReadableDatabase();
cursor = db.rawQuery("SELECT * FROM TB_USER WHERE username = '" + email + "'", null);
cursor.moveToFirst();
if (cursor.getCount() > 0) {
cursor.moveToPosition(0);
name = cursor.getString(2);
}
TextView lblName = findViewById(R.id.lblName);
TextView lblEmail = findViewById(R.id.lblEmail);
lblName.setText(name);
lblEmail.setText(email);
setupToolbar();
}
private void setupToolbar() {
Toolbar toolbar = findViewById(R.id.tbProfile);
toolbar.setTitle("Identitas Penyewa");
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == android.R.id.home) {
finish();
return true;
}
return super.onOptionsItemSelected(item);
}
}
8. Buat AlertDialogManager.java
Untuk membuat custom alert dialog.
package com.wijaba.travel.adapter;
import android.app.AlertDialog;
import android.content.Context;
import android.content.DialogInterface;
import com.wijaba.travel.R;
public class AlertDialogManager {
public void showAlertDialog(Context context, String title, String message, Boolean status) {
AlertDialog alertDialog = new AlertDialog.Builder(context).create();
alertDialog.setTitle(title);
alertDialog.setMessage(message);
if (status != null)
alertDialog.setIcon((status) ? R.drawable.ic_success : R.drawable.ic_fail);
alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
}
});
alertDialog.show();
}
}
9. Buat SessionManager.java
Berguna agar user tidak logout jika sudah menutup aplikasinya.
package com.wijaba.travel.session;
import android.annotation.SuppressLint;
import android.content.Context;
import android.content.Intent;
import android.content.SharedPreferences;
import com.wijaba.travel.activity.LoginActivity;
import java.util.HashMap;
public class SessionManager {
SharedPreferences pref;
SharedPreferences.Editor editor;
Context context;
int PRIVATE_MODE = 0;
private static final String PREF_NAME = "AzharPref";
private static final String IS_LOGIN = "IsLoggedIn";
public static final String KEY_NAME = "name";
public static final String KEY_EMAIL = "email";
@SuppressLint("CommitPrefEdits")
public SessionManager(Context context) {
this.context = context;
pref = context.getSharedPreferences(PREF_NAME, PRIVATE_MODE);
editor = pref.edit();
}
public void createLoginSession(String email) {
editor.putBoolean(IS_LOGIN, true);
editor.putString(KEY_EMAIL, email);
editor.commit();
}
public void checkLogin() {
if (!this.isLoggedIn()) {
Intent i = new Intent(context, LoginActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
}
}
public HashMap<String, String> getUserDetails() {
HashMap<String, String> user = new HashMap<>();
user.put(KEY_NAME, pref.getString(KEY_NAME, null));
user.put(KEY_EMAIL, pref.getString(KEY_EMAIL, null));
return user;
}
public void logoutUser() {
editor.clear();
editor.commit();
Intent i = new Intent(context, LoginActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
}
public boolean isLoggedIn() {
return pref.getBoolean(IS_LOGIN, false);
}
}
10. Buat DatabaseHelper.java
Fungsinya menyimpan hasil infput dari form menu Booking.
package com.wijaba.travel.database;
import android.annotation.SuppressLint;
import android.content.Context;
import android.database.Cursor;
import android.database.SQLException;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
public class DatabaseHelper extends SQLiteOpenHelper {
public static final String DATABASE_NAME = "db_travel";
public static final String TABLE_USER = "tb_user";
public static final String COL_USERNAME = "username";
public static final String COL_PASSWORD = "password";
public static final String COL_NAME = "name";
public static final String TABLE_BOOK = "tb_book";
public static final String COL_ID_BOOK = "id_book";
public static final String COL_ASAL = "asal";
public static final String COL_TUJUAN = "tujuan";
public static final String COL_TANGGAL = "tanggal";
public static final String COL_DEWASA = "dewasa";
public static final String COL_ANAK = "anak";
public static final String TABLE_HARGA = "tb_harga";
public static final String COL_HARGA_DEWASA = "harga_dewasa";
public static final String COL_HARGA_ANAK = "harga_anak";
public static final String COL_HARGA_TOTAL = "harga_total";
private SQLiteDatabase db;
public DatabaseHelper(Context context) {
super(context, DATABASE_NAME, null, 1);
}
@Override
public void onCreate(SQLiteDatabase db) {
db.execSQL("PRAGMA foreign_keys=ON");
db.execSQL("create table " + TABLE_USER + " (" + COL_USERNAME + " TEXT PRIMARY KEY, " + COL_PASSWORD +
" TEXT, " + COL_NAME + " TEXT)");
db.execSQL("create table " + TABLE_BOOK + " (" + COL_ID_BOOK + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
COL_ASAL + " TEXT, " + COL_TUJUAN + " TEXT" + ", " + COL_TANGGAL + " TEXT, " + COL_DEWASA + " TEXT, "
+ COL_ANAK + " TEXT)");
db.execSQL("create table " + TABLE_HARGA + " (" + COL_USERNAME + " TEXT, " + COL_ID_BOOK + " INTEGER, " +
COL_HARGA_DEWASA + " TEXT, " + COL_HARGA_ANAK + " TEXT, " + COL_HARGA_TOTAL +
" TEXT, FOREIGN KEY(" + COL_USERNAME + ") REFERENCES " + TABLE_USER
+ ", FOREIGN KEY(" + COL_ID_BOOK + ") REFERENCES " + TABLE_BOOK + ")");
db.execSQL("insert into " + TABLE_USER + " values ('azhar@gmail.com','azhar','Azhar Rivaldi');");
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL("DROP TABLE IF EXISTS " + TABLE_USER);
onCreate(db);
}
public void open() throws SQLException {
db = this.getWritableDatabase();
}
public boolean Register(String username, String password, String name) throws SQLException {
@SuppressLint("Recycle") Cursor mCursor = db.rawQuery("INSERT INTO " + TABLE_USER + "(" + COL_USERNAME + ", " + COL_PASSWORD + ", " + COL_NAME + ") VALUES (?,?,?)", new String[]{username, password, name});
if (mCursor != null) {
return mCursor.getCount() > 0;
}
return false;
}
public boolean Login(String username, String password) throws SQLException {
@SuppressLint("Recycle") Cursor mCursor = db.rawQuery("SELECT * FROM " + TABLE_USER + " WHERE " + COL_USERNAME + "=? AND " + COL_PASSWORD + "=?", new String[]{username, password});
if (mCursor != null) {
return mCursor.getCount() > 0;
}
return false;
}
}
11. Buat HistoryAdapter.java dan HistoryModel.java
Untuk mengambil list data dan mengimplementasikan apa saja yang akan tampil dan disimpan ke database.
HistoryAdapter.java
package com.wijaba.travel.adapter;
import android.annotation.SuppressLint;
import android.app.Activity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ImageView;
import android.widget.TextView;
import com.wijaba.travel.R;
import com.wijaba.travel.model.HistoryModel;
import java.util.ArrayList;
public class HistoryAdapter extends ArrayAdapter<HistoryModel> {
public HistoryAdapter(Activity context, ArrayList<HistoryModel> notification) {
super(context, 0, notification);
}
@SuppressLint("SetTextI18n")
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View listItemView = convertView;
if (listItemView == null) {
listItemView = LayoutInflater.from(getContext()).inflate(
R.layout.list_item_booking, parent, false);
}
HistoryModel current = getItem(position);
TextView idBook = listItemView.findViewById(R.id.id_booking);
idBook.setText("ID : " + current.getIdBook());
TextView tanggal = listItemView.findViewById(R.id.tanggal);
tanggal.setText(current.getTanggal());
TextView riwayat = listItemView.findViewById(R.id.riwayat);
riwayat.setText(current.getRiwayat());
TextView tvTotal = listItemView.findViewById(R.id.tv_total);
tvTotal.setText("Total :");
TextView total = listItemView.findViewById(R.id.total);
total.setText("Rp. " + current.getTotal());
ImageView imageIcon = listItemView.findViewById(R.id.image);
if (current.hasImage()) {
imageIcon.setImageResource(current.getImageResourceId());
imageIcon.setVisibility(View.VISIBLE);
} else {
imageIcon.setVisibility(View.GONE);
}
return listItemView;
}
}
HistoryModel.java
package com.wijaba.travel.model;
public class HistoryModel {
private String mIdBook;
private String mTanggal;
private String mRiwayat;
private String mTotal;
private int mImageResourceId;
private static final int NO_IMAGE_PROVIDED = -1;
public HistoryModel(String idBook, String tanggal, String riwayat, String total, int imageResourceId) {
mIdBook = idBook;
mTanggal = tanggal;
mRiwayat = riwayat;
mTotal = total;
mImageResourceId = imageResourceId;
}
public String getIdBook() {
return mIdBook;
}
public String getTanggal() {
return mTanggal;
}
public String getRiwayat() {
return mRiwayat;
}
public String getTotal() {
return mTotal;
}
public int getImageResourceId() {
return mImageResourceId;
}
public boolean hasImage() {
return mImageResourceId != NO_IMAGE_PROVIDED;
}
}
