StartActivityForResult kullanımı ve Kameradan Fotoğraf Alma ve Rehberden Telefon no Alma

By admin Android 0 Comments

Bilindiği gibi intent’leri aktiviteler arası dolaşırken yada herhangi bir intent’i çalıştırıp sonucunda data almak için kullanabiliyoruz. Bu uygulamada Aktivitemizi sonucunda bir data almak üzere çalıştıracağız. Bunu da “StartActivityForResult” ile yapacağız. Resimlerdeki gibi bir ekran görüntümüz olacak .
