Android 서비스에서 백그라운드 서비스의 진행률 백분율을 채우는 방법. 각 하위 항목에 다운로드 아이콘이있는 확장 가능한 목록보기가 있습니다. 해당 아이콘을 클릭하면 해당 항목과 관련하여 미디어를 다운로드해야합니다. 사용자가 다운로드 아이콘을 클릭하고 즉시 응용 프로그램을 닫으면 자원을 다운로드하고 다운로드 한 후에 알림을 표시해야합니다. 백그라운드 서비스에서 진행률 표시 줄을 채우는 방법을 알아낼 수 없었습니다. 제발 도와주세요. 서비스에 대한Android - 백그라운드 서비스에서 진행률 표시 줄 채우기 방법

super.onCreate(savedInstanceState);
setContentView(R.layout.android_listview);
expandableListView = (ExpandableListView) findViewById(R.id.expandableListView);
expandableListDetail = ExpandableListDataPump.getData();
expandableListTitle = new ArrayList<String>(expandableListDetail.keySet());
expandableListAdapter = new CustomExpandableListAdapter(this, expandableListTitle, expandableListDetail);
expandableListView.setAdapter(expandableListAdapter);
expandableListView.setOnGroupExpandListener(new ExpandableListView.OnGroupExpandListener() {
@Override
public void onGroupExpand(int groupPosition) {
