推荐答案
如果 Glendon Trullinger 的使用 onLongClickListener 的建议对你来说还不够，试试 GridView#pointToPosition(int x, int y)，您可以从 View.OnTouchListener，使用 MotionEvent 的 x 和 y 坐标.使用该位置，您可以使用 获取该位置的子视图这个答案，和/或您可以使用 AdapterView#getItemAtPosition(int)
If Glendon Trullinger's suggestion of using onLongClickListener isn't sufficient for you, try GridView#pointToPosition(int x, int y), which you can call from a View.OnTouchListener, using the MotionEvent's x and y coordinates. With that position, you can get the child view at that position using this answer, and/or you can get the adapter item itself using AdapterView#getItemAtPosition(int)
