Fragment inside ScrollView gives black background flickering

view story

http://stackoverflow.com – I have a LinearLayout in one of the activities as the main layout. I used Scrollview to encapsulated the LinearLayout. The Layout contains a fragment which displays a google map, but on scrolling it gave black background. I resolved the issue by using a transparent background inside a FrameLayout. The black background has gone, but during scrolling i get flickering black edges around the map. How to remove this? I tried setting the background of Scrollview to white color, but no change visible. The XML of the activity is -- <?xml version="1.0" encoding="utf-8"?> <ScrollView xmlns:a (HowTos)
