ExpandableListView常见问题

pressureListView.setGroupIndicator(null);  设置去掉默认的右侧的箭头

pressureListView.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() {
            @Override
            public boolean onGroupClick(ExpandableListView parent, View v, int groupPosition, long id) {
                return true; //设置父项不可点击
            }
        });

ExpandableListView中包含多个group，想要展开一个group时，其他group都关闭:

1. pressureListView.setOnGroupExpandListener(new OnGroupExpandListener() {    
2.     
3.         @Override    
4.         public void onGroupExpand(int groupPosition) {    
5.             for (int i = 0; i < getData().size(); i++) {    
6.                 if (groupPosition != i) {    
7.                     pressureListView.collapseGroup(i);    
8.                 }    
9.             }    
10.     
11.         }    
12.     
13.     }); 

expandablelistview的Group点击事件，onGroupClick的返回值false展开，true不展开

1.    pressureListView.setOnGroupClickListener(new OnGroupClickListener() {  
2.               
3.             @Override  
4.             public boolean onGroupClick(ExpandableListView parent, View v,  
5.                     int groupPosition, long id) {  
6.                 IsFlag=true;  
7.   
8.                 if(adapter.getGroupData().get(groupPosition).getList().size()==1){  
9.                     Bundle b=new Bundle();  
10.                     b.putInt("saveIndex", 0);  
11. //                  b.putString("mac", mac);  
12. //                  b.putString("deviceId", mDeviceId);  
13.                     b.putSerializable("datalist", adapter.getGroupData().get(groupPosition).getList());  
14.                     Intent i=new Intent(WappushBindingActivity.this,VideoPlayerActivity.class);  
15.                     i.putExtras(b);   
16.                     startActivity(i);  
17.                 }  
18. //              int groupCount = tt_list.getCount();     
19. //              for (int i=0; i<groupCount; i++){     
20. //                  if(i!=GroupPosition)  
21. //                      tt_list.collapseGroup(i);    
22. //               };   
23. //              Log.v("xulongheng*WappushBind*tt_list", "onGroupClick:"+previousX+"/"+previousY);  
24.                 return true;   //默认为false，设为true时，点击事件不会展开Group  
25.             }  
26.         });
