Listview Adapter problems with whitespace

I am creating a listView with adpater and I have a problem, I needed to add an image in the middle of the list to be in the direct corner, this image is just an arrow. how can I solve it, it takes up all the screen space even though I define the size of the image and that is for it to be in the direct corner.

segue XML  lista:
