我正在努力Expandable List View让它旁边有图像和文字。我有这个例子的大部分工作，我在这里找到了
但我不断得到一个Error
01-07 22:42:26.182: E/AndroidRuntime(28475): at gui.ExpandActivity$1.getChildView(ExpandActivity.java:115)
01-07 22:42:26.182: E/AndroidRuntime(28475): at android.widget.ExpandableListConnector.getView(ExpandableListConnector.java:450)
有什么想法吗？谢谢。
