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：

http://groups.google.com/group/Android-developers/browse_thread/thread/638f7ae1cb75b710/0154a631a2f38717?lnk=gst&q=setOnGroupClickListener#0154a631a2f38717

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;
							}
						});
