推荐答案

使用 setOnItemClickListener 在列表视图那么你将获得所选项目的ID（项目编号从0开始，但数据库_id列是从1开始，所以你应该送的id + 1 ，请证实）。

Use setOnItemClickListener on your Listview then you will get the id of the selected item (item id start from 0 but Database _id column is start from 1 so you should send id+1, please confirm this).

和使用意图发送的ID。

And send the id using intents.
