My Archive Uygulaması

06 Nisan 2026 16:36, Pazartesi 116 0

 

 

## 1. Uygulama Özellikleri

 

My Archive; kullanıcıların medya, okuma, istek listesi ve seyahat gibi farklı kategorilerde kişisel koleksiyonlarını yönetmelerine olanak tanır. Veriler cihaz üzerinde SQLite veritabanında saklanır. Uygulama çok dilli (Türkçe/İngilizce) ve gece/gündüz tema desteğine sahiptir.

 

- Kullanıcı kaydı ve oturum açma (SHA-256 ile şifrelenmiş, cihaz yerel)- 4 farklı raf: Medya, Okuma, İstek Listesi, Seyahat- Her rafa özel kategori türleri (oyun, kitap, ürün, şehir vb.)- 1–10 arası puan verme (SeekBar ile)- Not/yorum ekleme- Kayıt güncelleme ve silme- RecyclerView ile liste görünümü- Türkçe / İngilizce dil desteği (çalışma anında değiştirilebilir)- Gece / Gündüz tema desteği (Material3)- Tüm veriler cihazda SQLite ile saklanır, internet bağlantısı gerekmez

## 2. Kullanılan Temel Kavramlar


**SQLiteOpenHelper:** Android'de yerel veritabanı oluşturmak ve yönetmek için kullanılan temel sınıf. onCreate ile tablo oluşturulur, onUpgrade ile şema güncellenir.

 

**SharedPreferences:** Küçük anahtar-değer çiftlerini kalıcı olarak saklamak için kullanılır. Bu uygulamada oturum durumu ve dil tercihi burada tutulur.

 

**Activity:** Android'de her ekran bir Activity'dir. Uygulama; Dashboard, Login, Settings, Main (form), Goster (liste), ShelfBrowse ve ShelfEntry olmak üzere 7 Activity içerir.

 

**Intent:** Activity'ler arası geçiş ve veri taşıma için kullanılır. putExtra ile veri gönderilir, getStringExtra / getLongExtra ile alınır.

 

**RecyclerView + Adapter:** Büyük listeleri verimli şekilde göstermek için kullanılır. EntryListAdapter, her koleksiyon kaydını bir kart olarak render eder.

 

**BaseActivity:** Tüm ekranların miras aldığı ortak sınıf. Dil uygulama (attachBaseContext) ve oturum kontrolü (requiresLogin) burada merkezi olarak yönetilir.

 

**MaterialCardView / MaterialButton:** Google'ın Material Design 3 bileşenleri. Modern görünüm için kullanılır.

 

**SHA-256 Hash + Salt:** Şifreleri düz metin olarak saklamak yerine, rastgele bir salt ile birleştirip SHA-256 ile hash'leyerek güvenli biçimde saklamak için kullanılır.

 

**Locale / Configuration:** Uygulama dilini çalışma anında değiştirmek için Configuration nesnesi yeniden oluşturulur ve createConfigurationContext ile uygulanır.

## 3. Proje Mantığı

 
  • Uygulama açıldığında DashboardActivity başlar. BaseActivity.onCreate içinde oturum kontrolü yapılır;
  • kullanıcı giriş yapmamışsa LoginActivity'ye yönlendirilir.Dashboard'da 4 raf kartı bulunur.

  • Medya rafına tıklanınca goster.java (liste ekranı) açılır; diğer raflara tıklanınca ShelfBrowseActivity açılır.

  • Her iki liste ekranı da aynı activity_goster.xml layout'unu kullanır.
  • Yeni kayıt eklemek için form ekranı açılır: Medya rafı için MainActivity.java,

    diğer raflar için ShelfEntryActivity.java.

  • Her ikisi de activity_main.xml layout'unu paylaşır.

  • Form doldurulup kaydedilince veriler bizimdb.java üzerinden SQLite'a yazılır. Liste ekranı onResume'da her seferinde veritabanından taze veri çeker.
  • Dil değişikliği LocaleHelper üzerinden SharedPreferences'a kaydedilir. BaseActivity.attachBaseContext her Activity başlarken bu tercihi okuyarak doğru dili uygular.

---


## 4. Oturum Açma


  • LoginActivity, kullanıcı adı ve şifre alır.
  • "Giriş Yap" butonuna basılınca AuthDb.verifyUser çağrılır: veritabanından kullanıcının salt ve hash değeri okunur, girilen şifre aynı yöntemle hash'lenerek karşılaştırılır. 
  • Eşleşirse AuthManager.setLoggedIn ile oturum SharedPreferences'a kaydedilir ve DashboardActivity'ye geçilir.
  • "Hesap Oluştur" butonuna basılınca AuthDb.createUser çağrılır: rastgele 16 byte salt üretilir, salt:şifre birleşimi SHA-256 ile hash'lenir ve veritabanına yazılır.
  • BaseActivity.requiresLogin() varsayılan olarak true döner.
  • LoginActivity ve SettingsActivity bu metodu false döndürecek şekilde override eder, böylece bu ekranlara giriş yapılmadan erişilebilir.

---


## 5. Ayarlar: Dil ve Tema

 
  • SettingsActivity iki bölüm içerir:Dil: RadioGroup ile İngilizce veya Türkçe seçilir.
  • "Uygula" butonuna basılınca LocaleHelper.setPreferredLanguage ile tercih kaydedilir ve DashboardActivity FLAG_ACTIVITY_NEW_TASK | FLAG_ACTIVITY_CLEAR_TASK flag'leriyle yeniden başlatılır.
  • Böylece tüm Activity stack temizlenir ve yeni dil tüm ekranlara uygulanır.
  • LocaleHelper.wrap(context) metodu BaseActivity.attachBaseContext'ten çağrılır.
  • Her Activity oluşturulurken kaydedilmiş dil tercihi okunur, Locale ve Configuration nesneleri güncellenerek createConfigurationContext ile yeni bir context döndürülür.
  • Tema: Gece/gündüz teması Android sisteminin karanlık mod ayarına göre otomatik uygulanır. values/themes.xml gündüz, values-night/themes.xml gece temasını tanımlar.
  • Oturum: Ayarlar ekranında oturum durumu gösterilir.
  • Giriş yapılmışsa "Çıkış Yap", yapılmamışsa "Giriş Yap" butonu görünür.

## 6. Ekleme, Silme, Güncelleme ve Listeleme

 

İşlevleri


Ekleme (ekle):
  • Form ekranında başlık, tür, puan ve yorum girilir.
  • Kaydet butonuna basılınca veriler Intent ile liste ekranına taşınır.
  • Liste ekranı onCreate'de bu Intent verilerini okuyarak bizimdb.ekle() metodunu çağırır.
  • Bu metot ContentValues ile SQLite'a INSERT yapar ve tarihi otomatik olarak dd/MM/yyyy formatında ekler.

 

**Listeleme (getItems):**

  • bizimdb.getItems(shelf) metodu, belirtilen rafa ait tüm kayıtları ORDER BY id DESC (en yeni önce) sırasıyla çeker ve List<bizimdb.Item> döndürür.
  • EntryListAdapter.setItems() bu listeyi alarak RecyclerView'ı günceller.
  • Liste ekranı her onResume'da refreshList() çağırarak veriyi tazeler.

 

**Güncelleme (guncelle):**

  • Liste ekranındaki "Güncelle" butonuna basılınca kayıt ID'si Intent ile form ekranına gönderilir.
  • Form ekranı getItem(id) ile mevcut veriyi okur ve alanları doldurur.
  • Kullanıcı değişiklik yapıp kaydettiğinde bizimdb.guncelle() metodu UPDATE SQL komutu çalıştırır.

 

Silme (tumunuSil):

  • Liste ekranındaki "Arşivi Temizle" butonu bizimdb.tumunuSil(shelf) metodunu çağırır.
  • Bu metot ilgili rafa ait tüm kayıtları DELETE ile siler. Silme işlemi raf bazında toplu yapılır.

 

**Veri Modeli (bizimdb.Item):**

  • Her kayıt şu alanları içerir: id (long), shelf (raf adı), baslik (başlık), tur (tür anahtarı), puan (1-10), yorum (not), tarih (ekleme tarihi).
