응용 프로그램 클래스를 확장하는 경우 [add android : name]을 수정해야합니다. 귀하의 경우에는, 당신은 명단에 추가해야합니다

<application 
     android:name=".app.AppData"

안녕하세요 고마워. 이전에 추가했지만 구문이 잘못되었습니다. – Prax

다시 한번 감사드립니다 :) – Prax

입니다. 온라인에

AppData appData = (AppData) getApplication();

onItemClick 방법 중 하나입니다. getApplication 메서드는 AppData 클래스로 캐스팅하려고 시도하는 com.android.Application을 반환하지만 AppData 인스턴스는 아닙니다.

모든 인스턴스가 Application 인 경우에도 마찬가지입니다. 반대로 Application의 인스턴스는 자동으로 해당 서브 클래스의 인스턴스가 아닙니다.
