PopUp Penceresi veritabanını güncelleştirmiyor - Android

Question

Android Studio kullanarak bir tür oyun oluşturmaya çalışıyorum. Şimdiye kadar bir veritabanında saklanan oyuncuları gösteren bir gridview yaptım. GridView.setOnItemClickListener ile bazı sorunlar yaşadım, bunu gridView'ın Adparter.class içine koydum, bunu gridView'ın aktivitesine nasıl yapabildiğimi bilirseniz bunu bana söyleyin.

Sorunum şu ki, bir oyuncuya tıkladığınızda oyuncunun adını veya türünü değiştirebileceğiniz bir açılır pencere görüntülenir. Onayla düğmesine tıkladığınızda, veritabanı otomatik olarak güncellenecektir, ancak çalışmaz. Bu parçayı çalıştırıp çalıştırmadığınızı öğrenmek için Toast'ı kullanarak adım adım yapmaya çalışıyorum, sorun bağlam olabilir, ama belki de deliyim.

Size bazı resimler ve bununla ilgili kodu bıraktım.

Answer 1

size PopUp window class bir intent den id elde etmeye çalışmak olmasıdır.

Intent i = getIntent(); 
i.getIntExtra("Id", id); 

öyle olmalı: Sen bir şey yanlış yaptık

Intent i = getIntent(); 
id = i.getIntExtra("Id", id); //forgott id = here 

ve örneğin id=-1 için id için varsayılan bir değer vermelidir. Sorun şu ki, database numaralı telefonu güncelleştirerek, non value integer numaralı telefonu verdiniz ve bu nedenle tablonuzu güncellemek mümkün değil.
