Backgroundcolor of ExpandableListView while scrolling

Question

I have a problem with an ExpandableListView in my Android application. I've set a custom background color but while scrolling the list the color changes to black untill the scrolling has stopped. Is that normal or can you change the "onScrollColor"?

Answer 1

我遇到了此类问题，并在列表XML android:cacheColorHint = "#00000000"使用此属性解决了该问题

Make sure you use a ViewHolder for reuse of your Views inside your getView Method

like in this example: http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/List14.html

the background to this is that Android trys to reuse the Views while scrolling and if you dont obey the Caching Rules (eg Using a ViewHolder like in the example) you have that described problem.
