Selam Hasan,
Takip ettiğin eğitimde kodarı indir diye bir bölüm var sol tarafta oradan kodları indirip çalışan uygulamayı da görebilirsin.
Hatana gelecek olursa log da "com.example.test.MyListAdapter.getView(MyListAdapter.java:42) 01-09 09:31:29.019: " şu satıda hata olduğu görünüyor. Oğuz'unda dediği gibi resource bulamıyor. Yani main activity'nin xml'inin içine hem listview ı hemde textview ı koymuşsun böyle çalıştıramazsın. Listview'ı mainactivity'ine list in row una gelecek layout u da ayrı yapmalısın. Bunu örnek kodları indirince sende göreceksin.
Kolay gelsin.
Resources$NotFoundException Hatası almışsınız , yani bir yerde findViewById(R.id.xxxx) methodunda gerek id'yi vermemişsiniz bu methodları kontrol edin Layout'daki id'lerden.
