android控件expandablelistview

1、首次加载全部展开：

1
2
3
4

mDownloadListView.setAdapter(mDownloadAdapter);
        for (int i = 0; i < downloadGroup.size(); i++) {
            mDownloadListView.expandGroup(i);
        }

提醒：加载前别忘了判断adapter是否为空和有没有Group数据哦、

2、不能点击收缩：

mDownloadListView.setOnGroupClickListener(new OnGroupClickListener() {

            
            public boolean (ExpandableListView parent, View v,
                    int groupPosition, long id) {
                
                return true;
            }
        });
