在expandablelistview中设置页脚

Question

我创建了可扩展的listview.That列表视图包含父和子。我想在子布局中添加页脚。页脚在！st parent中正确设置。如果展开第二个父页脚页位置改变了。如何为所有父母设置页脚底部。

public class ExpandListAdapter extends BaseExpandableListAdapter {

    public static ArrayList<Child> ch_list= new ArrayList<Child>();

    private Context context;
    private ArrayList<Group> groups;
    Button button;
    CheckinAdapter adapter;
    String status;
    private ArrayList<Child> movielist = new ArrayList<Child>();
    public  ViewHolder viewHolder;

    public ExpandListAdapter(Context context, ArrayList<Group> groups) {
        this.context = context;
        this.groups = groups;
    }

    @Override
    public Object getChild(int groupPosition, int childPosition) {
        ArrayList<Child> chList = groups.get(groupPosition).getItems();
        return chList.get(childPosition);
    }

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



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



        final Child child = (Child) getChild(groupPosition, childPosition);

        if (convertView == null) {



            LayoutInflater infalInflater = (LayoutInflater) context
                    .getSystemService(context.LAYOUT_INFLATER_SERVICE);


//            if(childPosition ==0)
//            {
//                convertView = infalInflater.inflate(R.layout.footer_view, null);
//            }
//
//            //Here is the ListView of the ChildView
//            if(childPosition>0 && childPosition<getChildrenCount(groupPosition)-1)
//            {


                convertView = infalInflater.inflate(R.layout.child_item, null);
