I am having the same issue where my animations for specific items within a listview are random where they shouldn't be. In my application the user should be able to swipe any listview element from left to right and it would slide off screen. However, when this action is done a random item within the listview does the animation and not the selected one. I am implementing the ViewHolder method of the sample List14.java from the API demos. Does anyone know why this random behavior occurs for animations within listViews and how to overcome it?
