客户提出需求，要求分组列表单击一个group其他的group应该关闭，这个group的group标题应该顶头。
我网上大致找了一圈没找到相关的，于是去google group里搜索了下 ，发现有人提出了他的解决方法：
受此启发我想出了自己的方法，重写setOnGroupClickListener方法，使用flag控制：
定义flag记录列表状态
int expandFlag = -1;//控制列表的展开
重写onGroupClick方法
1.ExpandableListView listView = getExpandableListView();
2.
3.listView.setOnGroupClickListener(new OnGroupClickListener() {
4.
5. @Override
6. public boolean onGroupClick(ExpandableListView listView, View v,
7. int groupPosition, long id) {
8.
9. if (expandFlag == -1) {
2. //展开被选的group
3. listView.expandGroup(groupPosition);
4. //设置被选中的group置于顶端
5. listView.setSelectedGroup(groupPosition);
6. expandFlag = groupPosition;
2. } else if (expandFlag == groupPosition) { 3. listView.collapseGroup(expandFlag);
4. expandFlag = -1; 5. } else {
6. listView.collapseGroup(expandFlag);
7. //展开被选的group
8. listView.expandGroup(groupPosition);
9. //设置被选中的group置于顶端
10. listView.setSelectedGroup(groupPosition);
11. expandFlag = groupPosition; 12. }
13.
14. return true;
15. }
16.});

自己修改的：
mApplicationsList.setOnGroupClickListener(new OnGroupClickListener() {
@Override
public boolean onGroupClick(ExpandableListView listView, View v,int groupPosition, long id) {
TGLog.d("__groupPosition__expandFlag_" + groupPosition + "|" + expandFlag);
if(groupPosition == 0){
behDB.addOneBehCount("1806", 3);
}else if(groupPosition == 1){
behDB.addOneBehCount("1801", 3);
}
//实现：分组列表单击一个group其他的group应该关闭，这个group的group标题应该顶头。
if (expandFlag == -1) {
// 展开被选的group
if(mApplicationsList.isGroupExpanded(groupPosition)){
listView.collapseGroup(groupPosition);
}else {
if(groupPosition == 1){
listView.collapseGroup(0);
listView.expandGroup(groupPosition);
}else if(groupPosition == 0){
listView.expandGroup(groupPosition);
listView.collapseGroup(1);
}
}
// 设置被选中的group置于顶端
listView.setSelectedGroup(groupPosition);
expandFlag = groupPosition;
} else if (expandFlag == groupPosition) {
if(mApplicationsList.isGroupExpanded(groupPosition)){
listView.collapseGroup(expandFlag);
}else {
if(groupPosition == 1){
listView.collapseGroup(0);
listView.expandGroup(groupPosition);
}else if(groupPosition == 0){
listView.expandGroup(groupPosition);
listView.collapseGroup(1);
}
}
expandFlag = -1;
} else {
if(mApplicationsList.isGroupExpanded(groupPosition)){
listView.collapseGroup(expandFlag);
}else {
// 展开被选的group
if(groupPosition == 1){
listView.collapseGroup(0);
listView.expandGroup(groupPosition);
}else if(groupPosition == 0){
listView.expandGroup(groupPosition);
listView.collapseGroup(1);
}
}
// 设置被选中的group置于顶端
listView.setSelectedGroup(groupPosition);
expandFlag = groupPosition;
}
return true;
}
});
