Hocam tarih ve saati verdi ama şöyle garip bir durum var; 10 saniye öncesinin zamanını falan veriyor. Sanırım veri okunduğu zaman değil telefon uygulamayı açtığı zamanı gösteriyor. :)
İlgilendiğiniz için çok teşekkür ederim. Ben direkt reader run kısmına koydum şimdi de fonksiyon olarak yazayım. Duruma göre geri dönüş sağlarım olumlu veya olumsuz. Umarım olumlu olur. :D

}Basit bir fonksiyon yazdım. Bu fonksiyonu uygulamanda şu şekilde kullanabilirsin.
String date = changeDateFormat(System.currentTimeMillis());
txtResult.setText(qrcodes.valueAt(0).displayValue + date);Ayrıca aldığın hata farklı birşey de olabilir. Tam olarak hatayı paylaşırsan çözüm bulabiliriz.

}Ekledim fakat uygulama duruyor. Hala daha bir çözüm bulamadım. Yabancı kaynaklardı bu tarzda bir örnek yok. Yardımcı olunursa teşekkür ederim. Gerçekten işime yarayacak çünkü
Çok teşekkür ederim, bir deneyeyim. Umarım olur, çok işime yarar. :)
Merhabalar,
Öncelikle QR Code kullanmadım projelerimde ancak şöyle yapılabilir diye düşünüyorum. Kod okuması yaptığın fonksiyon içerisinde,
SimpleDateFormat s = new SimpleDateFormat("ddMMyyyyhhmmss");
String format = s.format(new Date());
bu şekilde tarih formatı oluşturup istediğin verinin yanına bu formatı bastırabilirsin. Tekrar belirtmek isterim daha önce QR Code kullanmadım. Umarım işine yarar. Kolay gelsin.
