표면보기 및 선형 레이아웃 및 onClick 이벤트

Question

선형 레이아웃에 표면 뷰를 추가하는 데 문제가 있습니다. 이미 사용 가능한 답변을 시도했지만 아직 파악할 수 없습니다. 내 목표는 다음 버튼을 클릭 할 때 로그인 화면의 맨 아래에 애니메이션을 렌더링하는 것입니다. 선형 레이아웃을 화면에 추가 한 다음 내 gameView 객체를 추가하려고했습니다.

이것은 loginActivity 및 게임보기 클래스입니다. xml도 추가했습니다.

Answer 1

이전에 setContentView (R.layout.main)에서 설정 한 활동 주 레이아웃에 myLayout을 첨부하지 않았습니다.

대신에 :

LinearLayout myLayout = new LinearLayout(this); 
myLayout.findViewById(R.id.gameLayoutView); 
myLayout.addView(gameView); 

이 작성해야 :

LinearLayout myLayout = (LinearLayout) findViewById(R.id.gameLayoutView); 
myLayout.addView(gameView);
