我正在尝试使用ExpandableListView构建基本的Android应用程序.将数据放入视图后,我只看到组,如果我点击它们不扩展的组.

适配器

    public class PhraseAdapter extends BaseExpandableListAdapter {

        private LayoutInflater inflater;

        private List data;

        public PhraseAdapter(Context context) {
            inflater = LayoutInflater.from(context);

        }

        public void setData(List data) {
            this.data = data;
        }

        public View inflate(int viewId) {
            View view = inflater.inflate(viewId, null);
            return view;
        }

        public void updateView(List categories) {
            setData(categories);
            notifyDataSetChanged();
        }

        static class ViewHolder {
            TextView name;
        }

        static class ViewChildHolder {
            TextView phonetix;
            TextView orginal;
        }

        @Override
        public Object getChild(int groupPosition, int childPosition) {
            return data.get(groupPosition);
        } …
