Android中ExpandableListView，每次只展示一个分组

// 只允许打开一个分组

        expandListView.setOnGroupExpandListener(new OnGroupExpandListener() {



            @Override

            public void onGroupExpand(int groupPosition) {

                for (int i = 0, count = expandTreeViewAdapter.getGroupCount(); i < count; i++) {

                    if (i != groupPosition) {

                        expandListView.collapseGroup(i);

                    }

                }

            }

        });
