Eclipse Layout sorunu

Kodda görsel objelerin tanımlamalarını yaparken yanlış id çağırmışsın muhtemelen. Logcat'te söylediğine göre onCreate metodunun içerisinde 31. satırda oluyor bu işlem. Buton tanımlamışsın ama AutoCompleteTextView'in idsini çağırmışsın.

AutoCompleteTextView 'i Button olarak görüyor kodunuzu relativelayoutta tasarlarken en üstte ne kullanıyorsanız koddada onu üste almanız faydalı olabilir
