我有一个自定义的可扩展列表视图，我正在尝试实现一个功能，这样我就可以通过提示用户键入标记名来向列表视图项添加“标记”。我希望这些标签以文本视图的形式出现在标题旁边。有什么办法吗？每个当前列表项都包含标题和子项。下面是我的自定义适配器代码：

public class CodeListExapandableListAdapter extends BaseExpandableListAdapter {
    private Context _context;
    private List<String> _listDataHeader; // header titles
    private List<String> _listDataHeaderOriginal; // used for search filter
    // child data in format of header title, child title
    private HashMap<String, List<String>> _listDataChild;

    public CodeListExapandableListAdapter(Context context, List<String> listDataHeader,
                                 HashMap<String, List<String>> listChildData) {
        this._context = context;
        this._listDataChild = listChildData;
        this._listDataHeader = listDataHeader;
        this._listDataHeaderOriginal = new ArrayList<>();
        this._listDataHeaderOriginal.addAll(listDataHeader);
    }

    @Override
    public int getGroupCount() {
        return this._listDataHeader.size();
    }

    @Override
    public int getChildrenCount(int groupPosition) {
        return this._listDataChild.get(this._listDataHeader.get(groupPosition))
                .size();
    }

    @Override
    public Object getGroup(int groupPosition) {
        return this._listDataHeader.get(groupPosition);
    }

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

    @Override
    public long getGroupId(int groupPosition) {
        return groupPosition;
    }

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

    @Override
    public boolean hasStableIds() {
        return false;
    }

    @Override
    public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) {
        String headerTitle = (String) getGroup(groupPosition);
        if (convertView == null) {
            LayoutInflater infalInflater = (LayoutInflater) this._context
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            convertView = infalInflater.inflate(R.layout.code_list_title, null);
        }

        TextView lblListHeader = (TextView) convertView
                .findViewById(R.id.codeListTitle);
        lblListHeader.setTypeface(null, Typeface.BOLD);
        lblListHeader.setText(headerTitle);

        if(isExpanded)
        {
            convertView.setBackgroundResource(R.color.blue_angel);
        }else {
            convertView.setBackgroundResource(R.color.app_blue);
        }

        return convertView;
    }

    @Override
    public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {
        final String childText = (String) getChild(groupPosition, childPosition);

        if (convertView == null) {
            LayoutInflater infalInflater = (LayoutInflater) this._context
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            convertView = infalInflater.inflate(R.layout.code_list_item, null);
        }

        TextView txtListChild = (TextView) convertView
                .findViewById(R.id.codeListItem);

        txtListChild.setText(childText);
        return convertView;
    }

    @Override
    public boolean isChildSelectable(int groupPosition, int childPosition) {
        return false;
    }

    //Required as this updates the list after an item delete!
    public void updateListsAfterDelete(List newList)
    {
        this._listDataHeaderOriginal.clear();
        this._listDataHeaderOriginal.addAll(newList);
    }

    //Need this to search inside the expandableListView
    public void filterData(String query){
        query = query.toLowerCase();
        this._listDataHeader.clear();
        if(query.isEmpty())
        {
            this._listDataHeader.addAll(this._listDataHeaderOriginal);
        }else
        {
            for(String str : this._listDataHeaderOriginal)
            {
                if(str.toLowerCase().contains(query))
                {
                    this._listDataHeader.add(str);
                }
            }
        }
        notifyDataSetChanged();
    }
}

代码列表标题的xml:
