Scroll gridview so a position is at the exact center

Question

I am making an android app and it uses a GridView. I made a search button so people can go to a specefic position in the GridView. I am currently using:

gridview.smoothScrollToPosition(index);

But in that doesn't center the position to the middle of the GridView.
This is what I want in an illustration:
enter image description here

Actually the problem is that the GridView stops scrolling from the moment the correct item is visible. Which means it will have a different place when scrolling up or down.

Have you tried using setSelection(), I've had some issues with smoothScrollToPosition() in the past — AndroidEnthusiast, Jan 15 '15 at 14:52

I have similar issues, so I manual compute it. v is the View to be centered:

   Rect rect = new Rect();
   mMediaGridView.getGlobalVisibleRect(rect);

   mMediaGridView.smoothScrollBy(v.getBottom()  - mMediaGridView.getScrollY()-rect.centerY()+v.getHeight()/2, 200);

This might be a duplicate of this problem: android: smoothScrollToPosition() not working correctly

I've experienced an issue like this before with listviews, I used setSelection() to solve it.

Not fixed, when I start scrolling from the bottom my item is on the top, when I start scrolling from the top my item is on the bottom. – Emiel Vandenbussche Jan 15 '15 at 15:08
