android-listview

问题 I have a simple array of Strings that I was displaying in a horizontal ListView with an ArrayAdapter . What I'm looking to do is: when the user selects an item from the ListView , make that item not clickable and change the background color of that item. Perhaps like a "grayed-out" look to it. I was looking into creating a custom Adapter and overriding the isEnabled(int position) method but I don't know how I would go about this. Any advice, suggestions, or help will be greatly appreciated

问题 I have a ListView that must display 4 items at a time. And I must scroll one item, one by one. After user scrolls the ListView, I must readjust the scroll to fit 4 items. I mean, I can´t show an item by half. Another question, is there any way to get the current ListView scrollY offset? Because the listView.getScrollY() method is from View, but not the Scroller object inside the ListView. 回答1: I've found an excellent solution. It works perfect for me. May be my answer will help someone. class
