我有带有自定义适配器的 ExpandableListView，在这个列表的 groupview 中，我使用动态属性作为它的 imagebutton src drawable，以这种风格声明：

g_view.xml

... android:src="?attr/img_add" ...

attrs.xml

attr name="img_add" format="reference" />

主题.xml

@drawable/ic_action_add_fdark

充气代码：*

LayoutInflater inflater = (LayoutInflater)
 mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                     convertView = inflater.inflate(R.layout.g_view, null);

当我在 g_view.xml 中使用src ="@drawable/img_add"时- 一切正常，但我需要使用动态 attr，但它根本不起作用......

经过三天的分析和失败，当希望几乎失去时..我修复了它！

我的适配器初始化代码是：

 adapter = new _sManagerExpAdapter(getApplicationContext(), cats, groups);

它必须是：

  adapter = new _sManagerExpAdapter(this, cats, groups);

现在，一切正常，感谢Patrick Arminio
