In getView(), if you are going to manage colors yourself, you need to *always* set the *right color*. *You* know what the right color is; Android does not. That being said, I question the entire approach that you are taking. If your ListView is being shown in conjunction with other widgets (e.g., managed by a fragment), where the content of those other widgets is determined by what the user tapped on in the ListView, then the notion of maintaining a highlight is appropriate. This UI pattern -- what Google refers to as the "master-detail pattern", is particularly useful on landscape large-screen devices. On Android 3.0+, Android has an "activated" style that you can use to manage the color for you. On older devices (e.g., you want master-detail on a Kindle Fire), then you might need to manage this more yourself, using the techniques that you are trying. In any other circumstance, I counsel you against doing what you are doing. For example, it may interfere with those using your app with a D-pad, trackball, arrow keys, or some other pointing device, as they need to distinguish which row is selected by the pointing device, so they know which row will be "clicked" when they, say, press down on the trackball or on the center D-pad button. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://github.com/commonsguy http://commonsware.com/blog | http://twitter.com/commonsguy _The Busy Coder's Guide to Android Development_ Version 4.1 Available! -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
