I have a ScrollView in an activity that contains a WebView and it looks like the ScrollView takes a little bit to load showing a black background until it has loaded. If I try and put a Layout behind the ScrollView with a white background then the fade that indicates that you can scroll turns white too.
I’ve tired putting a background colour on layouts both within and outside the scroll view; one affects the scrolling fade and the other doesn’t load leaving the black space, same with setting the colour on the scroll view itself.
If it takes time for the ScrollView to load, it probably means that you have some processing that can be done in background. You may want to move the processing to a background thread (using AsyncTask) and update the GUI in
onPostExecute.
