Android 如何在ExpandableListView中处理各种类型的行

我有4种不同类型的行，每种行都有自己的xml布局。我如何管理它们

我一直只得到第一排的类型，从来没有其他的。然后我想我还得处理回收工作。但是我不知道怎么做。我写下了一些代码，但我确实遗漏了一些东西。谢谢

代码如下：

public class ExpandableListAdapter extends BaseExpandableListAdapter {

    private Context _context;
    private List<String> _listDataHeader; // header titles

    // child data in format of header title, child title
    private HashMap<String, List<String>> _listDataChild;


    public ExpandableListAdapter(Context context, List<String> listDataHeader,
            HashMap<String, List<String>> listChildData) {
        this._context = context;
        this._listDataHeader = listDataHeader;
        this._listDataChild = listChildData;
    }

    @Override
    public Object getChild(int groupPosition, int childPosititon) {
        return this._listDataChild.get(this._listDataHeader.get(groupPosition))
                .get(childPosititon);
    }

    @Override
    public long getChildId(int groupPosition, int childPosition) {
        return childPosition;
    }

    @Override
    public int getChildTypeCount() {
        // TODO Auto-generated method stub
        Log.i("getChildTypeCount()", "getChildTypeCount()");
        return (4);
    }

    @Override
    public int getGroupTypeCount() {
        // TODO Auto-generated method stub
        return super.getGroupTypeCount();
    }

    @Override
    public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {

        String childText = (String) getChild(groupPosition, childPosition);
        int itemType = getChildType(groupPosition,childPosition);
