오류가 발생하는 Compview 클래스입니다.

벌금과 데이터베이스의 모든 데이터를 검색 할 수 노력하고 있지만, 때 내 compview 위해 같은 방법을 사용하고이 내 welcome1 클래스 클래스가 작동하지 않는 데이터에 액세스합니다. !! 당신이 String[] 배열을 만들 곳에서 adapter

adapter = new SimpleCursorAdapter(
    this, 
    R.layout.cmpinfo, 
    cursor, 
    new String[] {" Cname", "Cpost", "Ccriteria", "Cemail","Ccontact","Ccutoff"},

봐 ...

new String[] {" Cname", "Cpost", "Ccriteria", "Cemail","Ccontact","Ccutoff"}

문제는 from 매개 변수입니다 ... 당신은 space 전에이 Cname.

logact 출력이 도시 ... 잘 작동 내 welcome1 그 클래스에 대한 방법과 동일한 방법을 사용하여

column ' Cname' does not exist
