Android (Horizontal) ListView zoom in/out
===

Hi I am using the horizontal list view : https://github.com/vieux/Android-Horizontal-ListView/blob/master/HorizontalListView.java

to show several images and I would like to have a gradual zoom while people slide up and down on the screen. I know how to implement the touch event the only thing I don't know how to make the whole list view grow gradually. I don't want to zoom in on one image I want the whole list to zoom in/out gradually.


I have tried creating a new adapter giving each of the images a new hight and changing the adapter of the layout but the problem is the whole adapter is recreated and it produces a lag and doesn't look nice. 

I have tried with animations but the problem is once the animation is finished it goes back to the previous state.

I have tried doing the same thing with gallery but no luck either

Could someone advise me on how i should proceed as I don't know what else to try anymore.

Thank you in advance
