I'm a little confused why you are putting a WebViewWebView into a ScrollViewScrollView in the first place. A WebViewWebView has it's own built-in scrolling system.
Regarding your actual question, if you want the scrollbarScrollbar to show up on top, you can use view.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY) or android:scrollbarStyle="insideOverlay"
view.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY) or android:scrollbarStyle="insideOverlay"
