android - ViewPager and OnItemClickListener in ListView

Question

I'm working on creating a swipe-to-dismiss list view adapter. My basic methodology is to wrap the list item's view as the second view in a ViewPager and provide the necessary callbacks in the item change listener of the ViewPager. Through much pain I've got the View recycler working as intended, as well as ViewHolder and ViewBinder patterns implemented. I even managed to keep the ListView from taking over the touch events while the ViewPager is being scrolled without having to make a custom subclass of ListView (I can do it all from the Adapter).

Where I'm running into trouble is getting the selector and the OnItemClickListener to work. After looking at ListView's source it seemed that by overriding the ViewPager's hasFocusable() method to always return false (later on I'll pull this value from the child view) these things should have been reenabled. Unfortunately this is not the case. I've tried the setDecendantFocusability() workaround and I'm still stuck.

I'd like to avoid having to extend ListView if possible to provide the greatest amount of modularity. For similar reasons I don't want to add the selector to the ViewPager's background (if the dev changes the ListView's selector this wouldn't be reflected). Essentially I'm looking to make the ViewPager code transparent between the ListView and child View. Any ideas?

You are saying that you are making each list item a view pager, so that you can implement swiping to delete? If so... no no, this is not what view pager is for. First sorry it is just not intended to be used as an item in a list. Second it is for switching between views, not swiping to delete.

Unfortunately we don't have a sample code to show how to do this, but you can look at the platform's implementation of the notification pane or recent apps to get some ideas.
