Android Horizontal Images slider

Question

Hi I need to achieve a horizontal image scroller in which the images towards the centre will be zoomed more.

I could achieve somewhat close with horizontal listview and Circular drawable. Now I nedd means to give a focus to items in centre by applying a zoom How can this be achieved ?

This is what I have done so far

Thank You

Sorry that time by mistake half answer got posted, i am not sure with values but logic is proper , just calculate the mid element in onscroll listener and get the view and apply the animation.
This should be implemented in your onScrollListener of your listview.

 @Override
            public void onScroll(AbsListView view, int firstVisibleItem,
                    int visibleItemCount, int totalItemCount) {
                        int start = firstVisibleItem ;
                        int end = start + visibleItemCount ;
                       // calculate the mid element
                        int midElement = start + visibleItemCount/2;
                        View imageView = getchildAt(midElement - start);
                       //apply animation
                    }
        }
