how center a selected picture in the gallery?

how to center an image from开发者_StackOverflow中文版 gallery? If i use setSelection()

the gallery didn't are center, she move sometime in left sometime in right. She move in center only if the image was in extremities or if the selected image was in center.

If i do a second clique the picture go in center, i don't understand why. I use a setOnItemClickListener to change the image.
