나는 단지 startet 코딩 및 현재 안드로이드에 대한 내 채팅 클라이언트 작업이 문제 가지고 있어요 :
ViewRootImpl$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views.
내가 주변에 검색 한을하지만 그럴수는이 문제를 해결 아무것도 찾을 수가 . 짧은 용어로 원하는 내용 :
이 문제의 해결 방법 및 해결 방법에 대해 설명합니다. 왜 발생합니까?
내 코드를 수정하거나 해결책을 찾도록하십시오. 어떤 클래스가 액세스 할 수 있고 액세스 할 수 없는지에 대해서는 약간 분명한 것을 읽었지만 좋은 해결책을 찾지 못했습니다.
