Hey all,
First of all, i want to thank you Alessandro for this lovely component. I have also tested the dev-smart's HorizontalListView, and i am getting much better results with your view.
Unfortunately though, I am suffering from one main problem - while i can scroll nice and smooth, i can't catch onItemClicked events. I have followed the example you've provided in the demo activity. More frustrating is the fact that when i test the same views and layouts i am using, with android's native ListView, and dev-smart's HLV it actually works. I made sure i was using the correct classed, but still can't get it to work.
Would appreciate if you guys could take a look at my code, and see whether i am doing something terribly catastrophic. After looking at it for the entire day, i am positive i am missing something very fundamental
The element view:

ChannelSlideThumbnailsAdapter adapter = new ChannelSlideThumbnailsAdapter(getActivity(), channelSlideThumbnailsData);
mRecommendedSlide.setOverScrollMode( HorizontalVariableListView.OVER_SCROLL_ALWAYS );
mRecommendedSlide.setAdapter(adapter);
// Click event for single list row
mRecommendedSlide.setOnItemClickedListener( new OnItemClickedListener() {
@Override
public boolean onItemClick( AdapterView<?> parent, View view, int position, long id ) {
Log.e( TAG_LOG, "onItemClick: " + position );
return true;
}
});
Would appreciate any help with this.
Thanks,
