无法使用动态attr drawable来扩充视图

时间：2015-01-24 21:34:40

标签： android expandablelistview dynamic-attributes

我有自定义适配器的ExpandableListView，在这个列表的groupview中我使用动态attrs为它的imagebutton src drawable，以这样的样式声明：

g_view.xml

... 机器人：？SRC =＆＃34; ATTR / img_add＆＃34; ...

attrs.xml

attr name =＆＃34; img_add＆＃34;格式=＆＃34;参考＆＃34; /＆GT;

的themes.xml

@绘制/ 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 =＆＃34; @ drawable / img_add＆＃34; 时 - 一切都运行正常，但我需要使用动态attr ，但它根本不起作用......

P.S。 This我查了一下，没有任何帮助......

1 个答案:

答案 0 :(得分：1)

经过三天的分析和失败，当希望几乎消失时......我修好了！

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，由于Patrick Arminio

，一切正常
