推荐答案

在您的适配器，在那里你吹你的排布置，可以设置一个标记（与 setTag（）法）为每个删除按钮。该标签可以是该行的位置，这个删除按钮对应。

In your adapter, where you inflate your row layout, you can set a tag (with the setTag () method) to each delete button. The tag can be the row position that this delete button corresponds to.

后来，当有人点击该按钮，在 onClickListener ，你得到的按钮标记（与 v.getTag（）），解析为整数，并删除该行的那个位置。

Later, when someone clicks the button, in the onClickListener, you get the button tag (with v.getTag ()), parse it to integer and delete the row at that position.
