Ben bu etkiyi elde etmek için iki yoldan düşünebilirsiniz. 2 aktivitenin kullanılmasını gerektirecektir: biri tam ekran görüntüsü ile ikinci, geri dönüşümlü bir görünüm. Animasyon, etkinlik 1 ile etkinlik iki arasında geçiş arasında otomatik olarak uygulanacaktır. Bu çözüm işe yarayacak ve çok fazla kod gerektirmeyecek, ancak iki aktiviteyi senkronize halde tutma problemine gireceksiniz (RecyclerView'ın tam konumu gibi). Özelleştirme imkansız değildir, ancak çerçeveye sıkı sıkıya bağlı olduğunuzdan zor olabilir.
İkinci yol, aynı etkinlik içinde kalıyor ve geri dönüşümcü öğenizle tam ekran görünümü arasında geçiş yapmak için nesne animatörleri kullanıyor. Hile, RecyclerView öğesinin içinde bulunan görünümü canlandırmak değil, tam ekran görünümünüzü, RecyclerView öğesinin içinde yer alan görünümün sınırlarından hareketlendirmek değildir. Bu şekilde, ebeveynin sınırları tarafından sınırlanmayacaksınız. İleriye gittim ve son derece özelleştirilebilir olduğundan ve tüm animasyonlar üzerinde tam bir kontrol sağladığından ikinci çözümü uyguladım.
Bu örnek uygulama, çeviri ve ölçekleme animatörlerini içerir. Ekranın sol tarafında küçük kare pozisyon görünümünden canlandıracak. Bu davranış kolayca değiştirilebilir.
