我正在处理可扩展列表视图。但我收到错误“无法实例化类型 ExpandableListAdapter”。我的代码是---
public class Calculator_new_Pop extends Dialog implements View.OnClickListener{
ExpandableListAdapter listAdapter;
public Calculator_new_Pop(Activity parent) {
// TODO Auto-generated constructor stub
super(parent);
this._act = parent;}
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.calculator);
listAdapter = new ExpandableListAdapter(_act, listDataHeader, listDataChild);
//
}}
谁能帮我吗???
