效果图：
直接上代码
[java]
public class MyActivity extends Activity implements HandleClick{
private ExpandableListView listView;
private int lastClick = -1;//上一次点击的group的position
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
listView = (ExpandableListView)findViewById(R.id.listView);
//去掉前面的箭头图标
listView.setGroupIndicator(null);
MyExpandAdapter adapter = new MyExpandAdapter(this);
adapter.setHnadleClick(this);
listView.setAdapter(adapter);
listView.setOnGroupClickListener(new OnGroupClickListener() {
public boolean onGroupClick(ExpandableListView parent, View v,
int groupPosition, long id) {
if(lastClick == -1)
{
listView.expandGroup(groupPosition);
}
if(lastClick != -1 && lastClick != groupPosition)
{
listView.collapseGroup(lastClick);
listView.expandGroup(groupPosition);
}
else if(lastClick == groupPosition)
{
if(listView.isGroupExpanded(groupPosition))
listView.collapseGroup(groupPosition);
else if(!listView.isGroupExpanded(groupPosition))
listView.expandGroup(groupPosition);
}
lastClick = groupPosition;
return true;
}
});
}
public void handleClick(int type) {
Toast.makeText(MyActivity.this, "...点了一下...", Toast.LENGTH_SHORT).show();
}
}
适配器：
[java]
