İlginiz için Teşekkürler.
Bahsettiğim kod bir başka cihazda (Galaxy Gio) hatasız çalışmakta. Fakat note 2 ve S4 te hala bahsi geçen hatayı veriyor.
Kodu satır satır çalıştırdığımda "yeniNot içinde ki 'Kaydet' " butonuna bastıldığı an uygulama çöküyor.
Sizin istediğiniz kısımları tam olarak anlamadığımdan kodların tamamını paylaşıyorum, kusura bakmayın.

Merhaba,
ListView içeren Layout dosyanızı ve verileri ListView'a inflate ettiğiniz Activity dosyanızı paylaşmanız mümkün mü?
