Listede gezinirken zamanlayıcı titreder Benim app, liste görünümünde her öğe için geri sayım sayacı göstermek zorunda. Bunu CountDownTimer kullanarak yapabildim. Ancak, liste görünümü yukarı veya aşağı kaydırıldığında, zamanlayıcı titremeye başlar. Çok arandı ama bir çözüm bulamadı.ListView with Coundown zamanlayıcısı. Timer

Bir sorun, bunun bir kısmını özlediyseniz, if (mAuctionModel! = Null) { – Amsheer
@Amsheer Kodumu uyarladım ve yalnızca alakalı olanı gösterdim. Ayrıca, zamanlayıcı sadece bu model mevcutsa görünecektir – Nitish
bunu birden fazla cihazda/Android sürümlerinde test ettiniz mi? – bernlim
