为ExpandableListView自定义Item

02-20 16:28:22.920: E/AndroidRuntime(8523): java.lang.ClassCastException: android.widget.GridView cannot be cast to android.widget.TextView
02-20 16:28:22.920: E/AndroidRuntime(8523): at android.widget.SimpleExpandableListAdapter.bindView(SimpleExpandableListAdapter.java:247)

由于SimpleExpandableListAdapter  bindView方法217行使用的textview导致

解决方法是自定义adapter，继承BaseExpandableListAdapter
