我正在申请一种甲状腺,其中我有五个项目被列入清单。 每个项目的点击数据均来自陶尔,然后由我储存在地方数据库中。 现在我想在每一项目之前删除 but子,以便用户能够删除他选择的项目。 这就是如何从数据库中删除具体数值。 我曾尝试过激动,提出了一些办法,但并没有奏效。

Can anyone guide me how to accomplish this task?

最佳回答

您需要将该项目从职位上删除,然后再安排改编者,以便更新清单。

listofitems.remove(tempPosition);

setListAdapter(customAdapter );

删除数据库。 利用该职位获得补贴。

c.moveToPosition(position);
         id= c.getInt(c.getColumnIndex("_id"));

删除

myDataBase.delete(tablename, "_id=?", new String[] {Integer.toString(id)});
问题回答

您可以为改编者的项目安排立点听器,在座标上,您可以删除案文概览,并使用上述方法从数据库中删除。
