Expendable Listview与Android Child中的复选框没有获取值

Question

您好我尝试了这段代码，但是父级已全部设置且子级未获取任何值，并且父级点击甚至无法正常工作，并进一步展开列表以显示子级。

public class CategoryBaseAdapter extends BaseExpandableListAdapter {
    private Context mContext;
    private HashMap<Integer, List<ProfessionChildEntity>> mListDataChild;
    private ArrayList<ProfessionEntity> mListDataGroup;
    private HashMap<Integer, boolean[]> mChildCheckStates;
    private ChildViewHolder childViewHolder;
    private GroupViewHolder groupViewHolder;
    private String groupText;
    private String childText;
    public CategoryBaseAdapter(Activity context,
            ArrayList<ProfessionEntity> listDataGroup, HashMap<Integer, List<ProfessionChildEntity>> listDataChild) {
        mContext = context;
        mListDataGroup = listDataGroup;
        mListDataChild = listDataChild;
        mChildCheckStates = new HashMap<Integer, boolean[]>();
    }

    @Override
    public boolean areAllItemsEnabled() {
        return true;
    }

    @Override
    public int getGroupCount() {
        Log.d("--grpcount--",String.valueOf(mListDataGroup.size()));
        return mListDataGroup.size();
    }
    @Override
    public ProfessionEntity getGroup(int groupPosition) {
        return mListDataGroup.get(groupPosition);
    }

    @Override
    public long getGroupId(int groupPosition) {
        Log.d("---poisit",String.valueOf(groupPosition));
        return groupPosition;

    }

    @Override
    public View getGroupView(int groupPosition, boolean isExpanded,
            View convertView, ViewGroup parent) {
        groupText = getGroup(groupPosition).getDecription();

        return i;
    }
