Hi! I'm trying to understand the mechanics behind "highlighting" the "selected" list item. I have a list fragment, which might display with a secondary "details fragment" if the screen width allows it. In that case, I want to highlight the selected list item. In order to do so, the listview has defined choice mode of single, and also a defined selector:
listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE); listView.setSelector(R.drawable.listitem_selector); The list uses a custom view for layout, and when the view does not set the "android:background", the listitem_selector works -- it shows on the screen. When the row layout has a background set to a drawable (in my case, it is selector, consisting of colors), the listitem_selector does not work. I tried the methods explained in the stackoverflow post<http://stackoverflow.com/questions/2562051/listview-item-background-via-custom-selector>, but the approach does not work, at least not in my case. I'm obviously missing a part of the puzzle and I would appreciate any insight into this matter. One possible solution I see is modifying the backing adapter implementation and providing a different view based on the state of the item, but that seems like wrong approach -- I would have to update the adapter with information on the selected item and call notifyDataSetChanged, which would (I suppose) result in an unnecessary re-drawing of the whole list.
