我必须从列表活动调用mapactivity。每当用户点击listview上的项目，地图活动应该fire.But当项目被点击即时获取异常，您的地图活动类别找到。地图活动没有被调用列表项目单击监听器
如果我把简单胡亚蓉insted的地图activity..my代码工作well..i不知道为什么引发异常
这里是我的代码。
XML文件
<?xml version="1.0" encoding="utf-8"?>

如果我把简单的活动，并删除的MapView从XML文件那么我的代码工作好...但是当我在XML文件，然后引发异常它说，找不到（），这是从REFRENCED MAP onListItemClickListener活动
apesa：非常感谢你的朋友....我花了很多时间在这个错误背后...... – 2011-03-29 03:53:43
