OnCheckedChangeListener가 체크 박스로 작동하지 않습니다.

Question

내 작업 표시 줄에 체크 표시를하고 있습니다. 이 확인란은 내 listactivity의 모든 항목을 선택하는 데 사용됩니다. butsetOnCheckedChangeListener가이 체크 박스에서 작동하지 않습니다. 내 작업 표시 줄에 대한 별도의 레이아웃을 만들고 Java 코드를 통해 동적으로 확장합니다 (oncreate()). 아래 ListActivity에 대한 내 코드는 다음과 같습니다. 또한 webservice를 액션 버튼의 사용자 정의 레이아웃에서 보내기 버튼 클릭으로 호출해야합니다. 누구든지 가지고 있다면 해결책을주십시오. 난 그냥이 문제를 충족

여기 내 사용자 지정 레이아웃입니다. 이 방법으로 CheckBox의 뷰를 가져올 수 없습니다. 내가 당신을 위해 일할 수 있기를 바랍니다

View mCustomView=getActionBar().getCustomView(); 
selectAll = (CheckBox)mCustomView.findViewById(R.id.selectAll); 

:

LayoutInflater mInflater = LayoutInflater.from(this); 
View mCustomView = mInflater.inflate(R.layout.custom_app_share_action_bar, null); 
selectAll = (CheckBox)mCustomView.findViewById(R.id.selectAll); 

당신은 그것으로 변경해야합니다.
