原文：while (cursor.moveToNext()) {
MyGroupInfo myGroupInfo = new MyGroupInfo();
String groupname = cursor.getString(0);
// myGroupInfo.setGroupName(cursor.getString(0));
myGroupInfo.setGroupName(groupname);
myGroupInfos.add(myGroupInfo);
cursor.close();
db.close();
}
看了一下，原来我的sqliteDatabase对象关闭放在了while的里面。以至于报错了。所以解决方法就是把他们放到外面去，记得要关闭，但位置要看清。这篇小博文就作为自己开始真正工作的起点，也方便自己回忆学习。
