조각이 겹쳐서 조각을 최대화하고 최소화하는 해결책이 필요합니다.

Question

누구나 내게 아래의 문제에 대한 해결책을 말해 줄 수 있습니까? 파편을 사용하여 여러 채팅 창을 열고 싶은 간단한 채팅 응용 프로그램을 만들었습니다. 이 작업을 수행했지만 이제는 문제가 채팅 조각을 분리 할 수 ​​없으므로 모두 서로 겹칩니다. 버튼을 최소화하고 최대화하여 이러한 조각을 개별적으로 만들 수 있도록 솔루션을 제안하십시오. 코드 스 니펫 (snippet)을 제공하면 내가 adroid 개발에 익숙해 져서 도움이 될 것입니다.

감사합니다. & ragards, Anand Jagtap.

나는 탭 리스너를 사용하고 채팅 기록을 정적 변수에 저장하여 수행했습니다.

는 대신에 당신이 별도의 창에서 채팅을위한 활동과 같은 경고 상자를 만들 수 있습니다 최소화하거나 화면을 최대화에 대한 지원이 없습니다.
