조각이 있는데 조각에 listview를 설정하고 있습니다.안드로이드의 방향 변경 진행률 표시 줄 업데이트
public class AttachmentsFragment extends Fragment {
ListView lstView = null;
@Override
public void onActivityCreated(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onActivityCreated(savedInstanceState);
}
@Override
public void onAttach(Activity activity) {
// TODO Auto-generated method stub
super.onAttach(activity);
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//retains fragment instance across Activity re-creation
setRetainInstance(true);
objects = new ArrayList<AttachModel>();
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = null;
view = inflater.inflate(R.layout.tab_attachment, container, false);
lstView = (ListView) view.findViewById(R.id.listViewAttachment);
adapter = new AttachAdapter(getActivity(), 0, 0, objects);
lstView.setAdapter(adapter);
return view;
}
}

참고 : 이것은 내가하는 방식을 보여주기위한 것입니다. 이것은 단지 엿볼 수 있습니다. 내가 올바른 길을 가고 있는지 아닌지를 알아야합니다.
오리엔테이션이 변경되면 진행률 막대가 방향을 바꿀 위치를 유지하고 진행을 시작할 수 없습니다. 사전
