dikey
Ben android ile oynamak ediyorum ve şimdiye kadar öğrendiklerinizi test etmek için basit twitter uygulaması oluşturma ediyorum yatay. Ama anlamadığım bir sorunla karşılaştım. Tweet'leri getirmek için bir iş parçacığı oluşturdum, orada sorun yok, ancak daha sonra bu iş parçacığının ne zaman çalıştığını göstermek için bir ProgressDialog ekledim. Bunu yapmak çok sıradışı bir davranışa neden oldu. Kullanıcı Dikey yönden yatay yönlendirmeye dönerse, program beklendiği gibi davranır, sorun olmaz, ancak eğer geri dönerse, program bir pencerenin sızdırıldığını söyleyerek çöker.Android: rotasyonuna Crash
Sorun, yalnızca yataydan dikey düzen anahtarına gerçekleşir. İletişim kutusu çalışırken döndürmeyi denediğinizde sorunların farkındayım, ancak iletişim kutusunun dönmeden önce çalışıp bitirdiğinden emin olduk ve hala çökecek. İşte kodum: heres
