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]

public class MyExpandAdapter extends BaseExpandableListAdapter{

private Context context;

private String[] roomName= new String[]{"房间1","房间2","房间3","房间4","房间5"};

private String[] peoNum = new String[]{"1323人","6654人","86554人","6565人","7967人"};

private String[] startTime = new String[]{"马上开始","1分钟","2分钟","3分钟","4分钟"};

private HandleClick handleClick;

public interface HandleClick

{
