How do I add controlled scrolling in Android views

Question

I am trying to scroll a webview based on volume click button I added following code first,

    myWebView.scrollBy(0, 250);

this does scroll but then the scrolling is not smooth, view quickly alters, which is annoying. I tried adding a loop and a time delay, something like this

for(int i=-250;i<250;i++)
{
Thread.sleep(Math.abs(i/20));
myWebView.scroll(0,1)
}

For some strange reason this is not smooth either, the program waits for some delay and scrolling happens after that and that also is not controlled.

I tried scroller

    Scroller sc= new Scroller(myWebView.getContext());
    sc.startScroll(0, 0, 0, 250,250);

this didnt even scroll.

Is there any other way to get make it work? Or can there be some improvement in above code?
