Bir uygulama geliştiriyorum. İçinde bir liste görünümü kullanıyorum. Liste öğesini tıkladığımda, sonraki aktiviteye, yani ProfileActivity2.java'ya gitmelidir. İyi çalışıyor, ancak bu ProfileActivty2'de altta bir düğme var ve bu düğmeyi tıkladığımda benim app çöktü ve liste görünümünde durdu. Ve java.lang.Throwable hatası gösterir: setSoutLocked liste görünümü düzen dosyasında i.e setContentView. Bu hatayı nasıl çözebilirim?java.lang.Throwable gibi hatayı nasıl çözebilirim: setStateLocked?

kullanmak iç hata bu çizgide olduğunu düşünüyorum. –
