Question

OnItemClickListener中的position和id有什么区别

public void onItemClick(AdapterView<?> parent, View view, int position, long id)调试时候发现position与是一样的。

Answer 1

Parametersparent: The AdapterView where the click happened. view: The view within the AdapterView that was clicked (this will be a view provided by the adapter) position: The position of the view in the adapter. id: The row id of the item that was clicked. 上面是api文档里参数的解释。position是你点击的view在adapter的位置，id表示是你点击的第几行item至于说值一样应该是他们的位置一样 查看原帖>>

Answer 2

position 相当于 index，在 adapter 里的次序id 一个身份标识，如果是用 CursorAdapter，则为 Cursor 里的 _ID 字段值 查看原帖>>
