Android - ListView items maintaining style when scrolling

Question

I know that similar questions have already been asked but I do not understand what would be the correct approach of solving the issue, yet.

I would like to change the background color of a ListView row when the user clicks it. However due to Android reusing the row layouts when scrolling, the background color gets repeated for other rows. I am wondering what would be the correct approach of maintaining the original layout for all rows except the one changed programmaticaly and also maintain the changed layout information for that row for scrolling back. I am using a SimpleAdapter which is passed the rows layout's XML.

Regards

Your rows' capabilities within your ListView largely depend on the kind of Adapter you are using. In any Adapter where you manually construct or inflate the View per item, you can change the layout properties per item, as long as you do so within the Adapter. Simply add your background color code to when the item's View is built, and it will work like a charm. If you are not able to do so with the current Adapter, consider extending the current one or using a different adapter.

Note: I haven't placed code directly within this answer because where you add it depends upon your own implementation. For instance, I would add .setBackgroundDrawable() to bindView() in an extended CursorAdapter .

Hope this helps,
