            //Here: get the selected item object (or id)
        }

推荐答案

您应该能够做到：

items.moveToPosition(which)
String text = items.getString(THE_COLUMN_NUMBER)

的这参数是被点击的按钮，或选择该项目的位置（在列表中的情况下）。文档是这里。

The which parameter is either the button that was clicked, or the position of the item that was selected (in the case of a list). Docs are here.
