I have about 20 images. I have created buttons of each image and one ImageView. When a button clicked, the corresponding image will set to ImageView with enabled zooming and dragging. Then, replace it upon clicking the other button to move to the next/previous image. Now, I have to remove the buttons and replace it by implementing quick slide vertically. When I do quick slide from bottom to top, it will move to the next image. Then quick slide from top to bottom to move to the previous image. Also disable it if they reach first image or last image. Any guidance on the right direction on how to implement the quick slide paging using Android 2.1 is highly appreciated.
