自定义可扩展列表视图子视图看起来已禁用

Question

我制作了一个自定义的可扩展列表适配器。但是，我无法阻止我的孩子观看残疾。

在ExpandableListAdapter中，我添加了以下内容，但它没有改变任何内容;

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

关于此的任何线索？

注意：在我的子视图中，我有一个RelativeLayout，其中包含大量文本视图和ImageView

编辑：根据评论，这是整个适配器代码;

public class ExpandableListAdapter extends BaseExpandableListAdapter {

    private Context context;
    private Menu menu;

    public ExpandableListAdapter(Context context, Menu menu) {
        this.context = context;
        this.menu = menu;
    }

    @Override
    public Object getChild(int groupPosition, int childPosititon) {

        return this.menu.groups.get(groupPosition).items.get(childPosititon);
    }

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

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

        MenuItem item = (MenuItem) getChild(groupPosition, childPosition);

        if (convertView == null) {
            LayoutInflater inflater = (LayoutInflater) this.context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            convertView = inflater.inflate(R.layout.menu_list_item, null);
        }

        TextView name = (TextView) convertView.findViewById(R.id.item_name);
        TextView price = (TextView) convertView.findViewById(R.id.item_price);
        TextView description = (TextView) convertView.findViewById(R.id.item_description);
        TextView contents = (TextView) convertView.findViewById(R.id.item_contents);

        name.setText(item.name);
        price.setText(item.price + " TL");
        description.setText(item.description);
        contents.setText(item.contents);

        return convertView;
    }

    @Override
    public int getChildrenCount(int groupPosition) {

        return this.menu.groups.get(groupPosition).items.size();

    }

    @Override
    public Object getGroup(int groupPosition) {

        return this.menu.groups.get(groupPosition);
    }

    @Override
    public int getGroupCount() {

        return this.menu.groups.size();
    }

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

    @Override
    public View getGroupView(int groupPosition, boolean isExpanded,
                             View convertView, ViewGroup parent) {

        MenuGroup group = (MenuGroup) getGroup(groupPosition);

        if (convertView == null) {
            LayoutInflater inflater = (LayoutInflater) this.context
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            convertView = inflater.inflate(R.layout.menu_list_group, null);
        }

        TextView groupText = (TextView) convertView.findViewById(R.id.group);
        groupText.setText(group.name);

        return convertView;
    }

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

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